Development of electromagnetic shielding under the requirement of resistance and pressure synchronization

As shown in the figure below, the customer has the resistance requirement at the same time as the pressure is required. At this time, the relationship between the spring force and the resistance needs to be balanced. The best way is to rely on scientific test results to assist engineers in selecting materials or changing the design structure to improve the requirements! For this we have developed a pressure and resistance tester!

1. Independent research and development of pressure resistance tester. Specially designed test equipment for conductive foam compression resistance and pressure. The tester's resistance is 0.001Ω, the pressure measurement accuracy is 0.1g, and the resistance and pressure values of three different compression heights can be measured each time. The data is recorded after the compression height is maintained for 15 seconds, and then the measurement of the next compression height is performed.


2. Scientific verification of products using testing equipment. Improve the rebound force: first replace the different material verification, reduce the rebound force, the resistance also becomes larger, then change the conductive cloth stacking method, reduce the rebound force while ensuring the resistance is unchanged.
