Reliability And Performance Assurance

Shielding capability throughout the product's entire production cycle is guaranteed through reliability testing; shielding effectiveness (SE) is backed by data from performance verification laboratories.


Plug and unplug lifespan test

Thermal shock test

Vibration/Drop Test

Shielding effectiveness test

Contact impedance test


Repeatedly plugging and unplugging at a frequency of 10-25 times per minute, the mechanical wear and contact stability of the shrapnel after rated (over 100000 times) cycles


Verify the soldering strength between the shielding cover, shrapnel, terminals, and PCB


After vibration at specific frequencies and accelerations, the shielding cover shows no damage or detachment in appearance, and there is no significant decrease in shielding effectiveness


To measure the shielding effectiveness of the shielding cover in a specific frequency band (such as 30MHz-6GHz), it is usually required to reach 30dB or more, and the high-frequency band can reach 60dB or more


Use a milliohmmeter or four wire method to measure the contact resistance between the shielding cover, spring plate, and PCB ground, with a requirement of less than 10m Ω to ensure good grounding effect
