What is Rapid Prototyping of pogo pin connector?
Rapid prototyping is a process of rapidly manufacturing housing prototypes using CAD data through 3D printing or CNC machining. For the design of pogo pin connectors, using rapid prototyping can quickly obtain physical models for functional testing and dimensional verification. Through this process, engineers can identify potential issues in the design and make improvements before investing significant resources.
How to achieve rapid prototyping of pogo pin connector through 3D printing or CNC technology?
3D printing: Engineers can quickly manufacture prototypes of pogo pin connectors, accurately simulating connector shape, structure, and dimensions. 3D printing allows for the rapid production of complex shapes and rapid iteration, making design validation and optimization more convenient.
CNC machining: For pogo pin connectors that require high precision and durability, CNC machining provides a more precise solution. CNC technology can accurately cut complex-shaped components from metal or plastic materials, making it suitable for manufacturing functional and high-precision prototypes.

Design of low impedance high-frequency testing interface, What is Rapid Prototyping?
Nonlinear contact impedance: The thickness of ≥50μm gold plating layer and the curvature radius of the 0.05~0.1mm plunger jointly affect the impedance stability under skin effect. Johoty measured that the impedance jump of a regular pogo pin reaches ±25% at 6GHz.
High frequency crosstalk suppression: When the distance between adjacent pins is ≤1.5mm, the crosstalk (XTalk) needs to be suppressed to below -50dB through a grounding shielding ring design.
Mechanical durability: After 10,000 connections, the attenuation of contact pressure leads to an increase in impedance, requiring copper beryllium alloy with a three body spring structure and stainless steel to compensate for wear.

DFM checklist and FMEA and solutions, What is Rapid Prototyping？
DFM：
Contact force balance: It is recommended that the contact force of a single pogo pin be between 50-150gf. The pogo pin connector should ensure that the force distribution of each pogo pin is uniform, with a deviation of <15%,
Travel matching: The compression stroke of the pogo pin should be designed at 70-80% of the total stroke, with 20% redundancy reserved to prevent overvoltage,
Coplanarity control: The coplanarity of multiple pogo pin components should be ≤0.1mm, and Johoty often uses a laser micrometer for detection.
Beryllium copper alloy C17200 is preferred as the spring material, with an industrial standard gold plating thickness of ≥ 0.8μm. Use PPS or LCP materials with a temperature resistance of >200℃ for housing. Pass salt spray test for 48 hours and the plug-in life test for ≥10,000 times.
Failure Mode Effective Analysis:
Unstable contact resistance, surface oxidation/pollutant accumulation, using self-cleaning coating technology. When the strain amplitude exceeds 0.3% due to fatigue fracture of the spring, the service life sharply decreases. Johoty’s three-level heat treatment process increases fatigue life by 300%.
