Simulated Environmental Change Testing
The ICT spring test probe can be used to simulate different temperatures and humidities to test PCBA stability in various environments. A circuit board is like a plant, and changes may affect its health in the environment. ICT test probe is like a simulator for climate change, it can help engineers detect whether circuit boards can still function properly in cold, humid, or hot, ensuring good performance in any environment.
Spring Test Probe Advantages:
Improve Testing Efficiency
The ICT spring test probe can improve the testing speed, allowing test engineers to complete more testing work in a shorter time. It’s like when you’re working on a project, if the tools are complete and efficient, you can finish it faster.
Reduce Physical Damage
The ICT spring test probe designs can help reduce physical damage to circuit boards. It’s like carefully holding something and not letting it fall off. When using Johoty’s test probes, it will not cause significant scratches or damage to the circuit board, thereby improving the reliability of the product.
Reliable Contact Force
Johoty’s spring test probe can maintain stable contact force for a long time. This means you can ignore the usage times it is used, its contact effect will not deteriorate. You can imagine the test probe as a very powerful suction cup, always firmly holding onto the object without loosening.
Accurate Measurement of Voltage and Current
The ICT spring test probe can accurately measure voltage and current in circuits. It is like an electronic thermometer that can help TE engineers ensure that the circuit is working properly and there are no issues with high or low voltage.
FAQ
The spring test probe can provide constant contact force and ensure a stable connection with the tested board. The test probe tip aligns with the test point and establishes a physical connection through spring compression and release. They can enable the stable transfer and measurement of signals or currents.
When you select a spring test probe to use in ICT or FCT, you need to think about its size, stroke, and probe pitch first. and others, including contact resistance, rating current, required contact force, and your testing environment. We need to know the specific requirements and testing conditions of the tested board (UUT), this helps define test probe tips.
Lower contact impedance results in higher signal quality. A good test probe can minimize contact impedance, enhancing test accuracy and reliability.
