Compliant PCB Connection Works with Your Tolerances
Conventional board-to-board connector depends on two rigid mating halves reaching a narrowly controlled position. When the enclosure or PCB thickness introduces variation, the connector may be exposed to incomplete mating. Also, standoff, mounting screw or assembly process may meet excessive insertion force or mechanical stress.
Board-to-board pogo pin connector uses spring loaded pogo pins to maintain force against soldering pad or target area. Working stroke of each pogo pin can absorb part of axial tolerance while maintaining a repeatable electrical path. This is helpful when your design at the following conditions.
Control an uncertain PCB stack height：
Johoty can design free/working height and total stroke based on actual minimum and maximum distance between your PCBs. We select a right working compression from complete tolerance stack instead of a board spacing alone.
Compensate for assembly variation：
Spring travel of board-to-board pogo pin connector can accommodate axial variation. Johoty can manage lateral, angular and rotational misalignment well by guide posts, lead-in chamfers, floating housings and enlarged target areas.
Connect replaceable modules without a fragile socket：
A pogo pin array can connect a replaceable daughterboard, sensor module, battery module or control board. It doesn’t require a conventional male contact to enter a delicate female socket.
Combine power, signal and ground in one board-to-board connector：
Board-to-board connector can use different pin diameters, spring forces, tip and pin assignments in the same housing. Johoty can integrate power contacts, signal contacts, ground contacts and presence-detection contacts into a single board-level interface.
Simplify assembly and field service：
A compression-mated interface can minimize manually inserting or unplugging a conventional connector during production, maintenance or module replacement.
Start with Design Challenge, Not Catalog Part Number
Johoty customizes board-to-board pogo pin connector by electrical, mechanical, environmental, production conditions, because it’ll remain stable in real device.
PCB relationship and orientation:
Johoty need to know whether 2 PCBs are parallel, vertical, coplanar, or mounted at an offset. We will evaluate vertical, horizontal, right-angle, and interposer-style accordingly.
Minimum and maximum board spacing:
Johoty always designs board-to-board pogo pin connector around the complete stack-up range. For us, it’s critical sizes for PCB thickness, enclosure dimensions, standoffs, screws. And it’s also important for adhesives, gaskets, warpage and assembly tolerances.
Contact count and pin assignment:
Johoty can provide the required number of power, signal, ground, detection and reserved contacts. A sketch can help Johoty separate high-current paths, sensitive signals and return paths before finalizing the housing.
Electrical load:
Johoty needs continuous current, peak current, duty cycle, operating voltage in your application. And knowing switching condition, acceptable voltage drop and maximum temperature rise. For a reliable design, current rating is very important.
Signal requirements:
For high-speed or noise-sensitive signals, Johoty needs to know the protocol, data rate, differential impedance. Rise time, allowable insertion loss and crosstalk limits are also the key parameters. Johoty can evaluate differential-pair placement, ground shielding and specialized contact structures then.
Mating frequency:
Johoty needs to know board-to-board pogo pin connector is assembled once, serviced occasionally or mated up to 500k times. We will design plating thickness, tip geometry, target-pad finish, spring force and working stroke based on your life cycles.
Operating environment:
Temperature range, humidity, dust will affect the performance of board-to-board pogo pin connector. Also, it’s also determined by vibration, shock, salt exposure, cleaning chemicals and sealing. A board-to-board pogo pin connector isn’t automatically waterproof. Johoty need to design ingress protection well through the complete housing and sealing.
Production process:
Johoty needs to know you will mount board-to-board pogo pin connector by SMT reflow, through-hole soldering, press-fit installation. Also, it’s helpful to know your selective soldering, insert molding, overmolding or mechanical retention.

How to Ensure Reliability of Board-to-Board Pogo Pin Connector?
Compression must be designed from the full tolerance stack:
Johoty selects a pogo pin based on its free height fitting the nominal board spacing. We calculates the connector condition at the minimum and maximum possible PCB distance.
At maximum board spacing, the connector must retain enough compression to maintain the required contact force. At minimum board spacing, the plunger must remain safely within its available travel. Johoty needs to ensure not to bottom out or create excessive force on the PCB.
We always review PCB thickness and flatness, enclosure and standoff tolerances, screw or clip position, adhesive and gasket thickness. And housing dimensional tolerance, solder-joint height, thermal expansion, and expected PCB deflection. Johoty review a force-travel curve and the dimensional stack before approving the final working height.
Current is rated by temperature rise, not by diameter alone:
Johoty always clearly states a reliable current specification by the ambient temperature, continuous or intermittent load. It‘s also indispensable for duty cycle, acceptable temperature rise and number of adjacent loaded contacts.
When several power contacts operate together, mutual heating can reduce the safe current of each contact. Johoty can evaluate larger contact diameters and parallel power contacts together. We also look into shorter current paths, lower-resistance materials and dedicated PCB copper areas.
For mixed power-and-signal connectors, Johoty always separates power contacts from sensitive signal contacts. We can also support them by dedicated ground or return contacts.
Complete pin field determines high-speed performance:
When placed in an uncontrolled high-speed layout, a pogo pin may be suitable mechanically but not electrically. We always design high-speed board-to-board pogo pin connector carefully:
Johoty follows the procedure of signal-to-ground arrangement, differential-pair symmetry, and contact length. We must pay attention to return-path continuity, pitch and spacing, and housing dielectric properties. We also focus on stub length, crosstalk, and connector-to-PCB transition geometry.
Johoty can design ground-signal-ground arrangements, differential contact patterns or coaxial-style spring contact when clients’ project requires controlled signal integrity.
Cycle life and environment with matched plating:
Johoty can define gold plating or composite plating to improve corrosion resistance as well as maintain low contact resistance. An appropriate gold thickness can achieve expected mating cycles, contact force. Also, including wiping action, target finish and contamination level.
When we design a low-cycle internal module, its gold plating is different from frequently serviced industrial interface. Johoty always defines a right plating specification after reviewing the actual usage. We won’t apply one plating thickness to every project.
Target pad as part of board-to-board pogo pin connector
Johoty always proposes the opposing PCB pad together with the pogo pin. We can ensure its diameter, shape, surface finish and position tolerance to enhance alignment margin, anti-wear and electrical stability.
For high life cycles, Johoty can offer dedicated target contact for high wear resistance instead of basic PCB pad. For blind-mating, we can also enlarge or combined target area with mechanical guiding features.
Johoty can propose the target pad in the approved connector drawing or application note.
Mechanical misalignment management:
Spring travel primarily compensates for axial variation. However, many clients don’t know this and try to solve unlimited lateral or angular error. If so, Johoty suggestion is to use our ball point pogo pin instead of any types of pogo pins.
Johoty can integratedly design guide posts, guide holes and polarization features. During design, we always think about lead-in chamfers, floating connector plates, and enlarged target pads. Also, we never forget rounded or crown-style contact tips, mechanical stops, and housing features that prevent side loading.
We must ensure guide the PCBs into a controlled mating condition before the contacts are exposed to damaging side force.
Sealing around the complete assembly:
Standard spring loaded pin isn’t inherently waterproof due to its moving plunger. However, sealed board-to-board pogo pin connector requires a housing, gasket, O-ring, injection molding or enclosure interface. It can effectively prevent water and contaminants from reaching the moving contact area.
Johoty can review the required IP level, pressure condition, cleaning method and enclosure geometry before recommending a sealing architecture. In brief, we can design various perfect waterproof board-to-board pogo pin connectors for you.
Total connector force must not overload the PCB:
The spring force of one pogo pin may appear low. But, total compression load is the force per pin multiplied by the number of pogo pins.
Obviously, a 60 pin connector array requires a different PCB-support from a 4 pin connector. Johoty can evaluate the total load, mounting-point location, housing support and PCB deflection risk. Sure, we need to finalize the pogo pin count and spring force in advance.
Custom Configurations of Board-to-Board Pogo Pin Connector
Low-profile board-to-board pogo pin connector
For compact wearables, handheld electronics, sensors and slim modules, Johoty can reduce free height, working height and housing thickness. And, Johoty can maintain a controlled compression stroke.
Johoty always studies how to achieve the required stroke, spring force and current within the available Z-height. We won’t reduce height at the expense of reliability.
High-current board-to-board pogo pin connector
Johoty can design power pogo pins by larger diameters, low-resistance. Including specialized internal structures or parallel pin arrangements. We can also integrate signal and sensing pogo pins into the same housing.
Sure, we need to evaluate current density, temperature rise, adjacent-pin heating and PCB copper capacity before confirming the rating.
High-density spring-loaded PCB connector
Johoty can provide multi-row pogo pin arrays with a compact interface for modular control boards. And for diagnostic equipment and replaceable electronic assemblies.
We design high-density with careful management of connector flatness and total spring force. And, PCB support, pin-position tolerance, electrical isolation and signal return paths.
Blind-mate board-to-board pogo pin connector
Johoty can design a blind-mate by guide features, lead-in geometry, enlarged targets and controlled float. We need to ensure two modules connect well when operator can’t see the contact interface directly.
We design and ensure 2 connectors mechanical guide engages before pogo pins experience significant compression or side load.
Right-angle board-to-board pogo pin connector
A right-angle spring-loaded connector can link perpendicular or offset PCBs. However, a vertical connector may interfere with the enclosure, display, battery or mechanical structure.
Johoty can review and check SMT, through-hole and mechanically retained right-angle configurations.
Double-ended pogo pin connector
With reliable housing holding in client’s device, Johoty can design double-ended spring loaded connectors for two target PCBs. Then, you won’t need to permanently solder a conventional connector to both PCBs.
Johoty can support you to simplify module replacement, test access and compression-mounted assemblies by it. For precondition, we need to know a controlled board spacing, parallelism and mechanical retention.
Mixed power-and-signal connector
Johoty can combine different contact sizes and assignments in one housing. We design it to transmit power, ground, communication signals and identification signals.
Johoty can also design first-mate or last-break contact sequencing through controlled pogo pin height. Our segmented connection solution is suitable for an intentional connection order.
Sealed spring-loaded board connector
For outdoor equipment, industrial sensors and exposed modules, Johoty can integrate spring loaded pins into a custom sealed housing.
Johoty needs to review and test the complete connector, gasket, enclosure and assembly method. Then, we can ensure the ingress protection for a sealed spring-loaded board connector.
Validation Plan Before Clients Approving Board-to-Board Pogo Pin Connector
Johoty doesn’t treat a laboratory result from one geometry as a universal rating for every custom connector. We associate each critical performance value with the tested part number, drawing revision and test condition. We can provide our clients with clear, relevant and repeatable test conditions before manufacturing a prototype, sample, mass production.

FAQs of Board-to-Board Pogo Pin Connector
What information does Johoty need to design a custom board-to-board pogo pin connector?
Johoty needs your PCB orientation, available connector area, minimum and maximum board spacing. It’s important for us to know contact count, pin assignment, continuous and peak current. Also critical for signal type, required mating cycles, operating environment and assembly process as well.
Your STEP model, PCB drawing or marked PDF allows us to identify mechanical conflicts and tolerance risks earlier. When complete information isn’t yet available, Johoty can provide a design-input checklist to help your team define the missing requirements.
How should I choose the working height and stroke?
Johoty designs working height based on the full minimum-to-maximum PCB spacing rather than the nominal distance alone.
We need to keep pogo pin retain adequate compression at the largest spacing. Also, we must guarantee sufficient overtravel at the smallest spacing. Before Johoty finalizes the free height, working height and stroke, we need to study many specs and parameters. This includes PCB thickness, housing tolerance, standoffs, and screws. Also, we double check solder height, gaskets, warpage and thermal expansion.
What compression should a board-to-board pogo pin use?
Johoty defines correct compression depends on the force-travel curve and the tolerance stack. In our designs, we place the working point within the 60%~70% of the available travel. We don’t place it near the uncompressed or bottomed-out position.
We design the final compression for adequate minimum contact force without producing excessive total load on the PCB.
Can a pogo pin connector compensate for PCB misalignment?
In board-to-board pogo pin connector, spring travel mainly compensates for axial or Z-direction variation. It is only a standard pogo pin connector, you should control the lateral, angular and rotational errors. Because they are related to guide posts, lead-in chamfers, enlarged target pads, floating housings or other mechanical alignment. For example, the lateral force, perfect solution should be ball point pogo pins instead of standard pogo pins.
Johoty can evaluate a misalignment-tolerant board-to-board pogo pin connector. In usual, we define the allowable offset in the approved design rather than assumed.
Can Johoty combine power, signal and ground contacts in one pogo pin connector?
Yes. Johoty can flexibly design power-and-signal connector by different pogo pin diameters, spring forces, positions and assignments in one housing.
We can effectively separate power contacts from sensitive signals. We can also provide appropriate ground returns and use multiple contacts in parallel. For temperature rise, voltage drop, crosstalk and total compression force, we can finalize the final layout.
How much current can Johoty board-to-board pogo pin connector carry?
Johoty can define the current based on contact diameter, internal structure, materials, and working stroke. We also refer to contact resistance, ambient temperature, duty cycle, PCB copper and adjacent pogo pin quantity.
Yes, we can design high current up to continuous 50A per pin. But we advise confirming the final rating through a defined temperature-rise and voltage-drop test. Johoty can achieve higher total current through specialized contacts or parallel power pogo pins.
Can Johoty pogo pins handle high-speed signals?
Yes, we can design high speed pogo pins and high speed pogo pin connector. However, Johoty hints we shouldn’t treat a standard pogo pin layout automatically as a controlled high-speed interconnect.
High speed pogo pin connector requires low contact resistance, low profile, even coaxial pogo pins. For us, Johoty need to design its layout carefully based on the protocol, data rate, and nearby ground contacts. According to many validations from clients’ project, we can design <12Gbps high-speed board-to-board pogo pin connector.
How many mating cycles can the board-to-board pogo pin connector achieve?
Cycle life is influenced by working stroke, contact force, plunger tip, plating thickness. At the same time, target-pad finish, contamination, alignment and cleaning method can also impact to it.
Johoty can customize up to 500,000 mating cycles if it’s possible to get the right dimensions, materials, and pricing enough. For your specified cycle life, we should verify it by the approved connector, target surface and working compression.
What contact materials and plating are available?
We design contact components based on brass, beryllium copper or other copper alloys, with gold over nickel plating. Springs are often made of stainless spring steel or SUS631, music wire SWP-B, beryllium copper or another spring alloy.
Johoty selects the material and plating thickness according to clients’ required conductivity and spring force. As well as wear, corrosion exposure, cycle life and cost. We state the final material and plating specification in the approved drawing. We always get a alignment with our clients on the finalized materials and gold plating thickness.
Are SMT, through-hole and right-angle available in board-to-board pogo pin connector?
Yes. The 3 types are the pupular board-to-board pogo pin connector. Johoty can evaluate SMT board-to-board pogo pin connectors, through-hole connectors, right-angle connectors. Also, we can offer press-fit contacts, double-ended contacts and mechanically retained assemblies.
We always select the mounting method according to your PCB space, reflow temperature. And, we think about mechanical load, serviceability and production process.
Can a board-to-board pogo pin connector be IP67, IP68 waterproof?
Certainly. Johoty can make IP67, IP68 waterproof. However, we should not assume the spring loaded pogo pin to be waterproof. Because we design a waterproof or dust-resistant based on a complete sealing system around the connector. That is, it needs special inner structure and goes through the process of injection molding.
Johoty can design a sealed housing by gaskets, O-rings, overmolding/injection molding, enclosure-level seals. We test the final IP performance on the completely assembled product underwater.
How long does a custom board-to-board pogo pin connector project take?
Johoty customizes board-to-board pogo pin connector with CNC housing in 2 weeks. And custom housing or injection molding in 4 weeks. So, the lead time depends on the pin number, pitch, and housing materials. And, the lead time will be longer, If you have high housing complexity, electrical requirements and validation scope.
For many custom designs, Johoty can target first engineering samples in two weeks after approving the drawing. For high-density, high-speed, high-current, and small or sealing, we hope to get additional engineering and manufacturing time.
A project schedule for board-to-board pogo pin connector, we should identify the DFM review, drawing approval, prototype. EVT/DVT validation, design revision and production-release are our considerations.
