Release time:2018-10-16    Clicks: Click

 
There are four ways to test the performance of the light touch switch. Today we will give you a detailed introduction, so that you can clearly understand the parameters and performance before using the light touch switch.
This article will introduce four kinds of common methods about the performance test of light touch switch in detail.

Test method of touch switch performance, humidity test
METHODS: Place it in 90-95% RH environment at 40 6550
Test standard: Contact resistance, insulation resistance are within the standard range, and there is no sign of switch performance damage.
Performance test method of touch switch two, cold resistance test
Method: Place it in a temperature environment of minus 20 65507
Test standard: Contact resistance, insulation resistance are within the standard range, and there is no sign of switch performance damage.
Test method of touch switch performance three, high temperature resistance test
Method: The product is stored at 280
Test standard: resistance, acrylic springback, shape, etc. there are no signs of damage. Switch performance is still undamaged.
Test method of touch switch performance four. Soldering resistance test
1. Weldability test:
Methods: The welding feet were soaked in the tin pool about 2 mm deep, the test temperature was about 230 5, and the holding time was 3.5 seconds.
Test standard: over 80% of the foam foot will be covered by tin.
2. Soldering resistance test:
Method: The temperature of soldering furnace is controlled at 260 65507
Test standard: the switch has no deformation and can meet the electrical performance. The application of abnormal pressure is invalid.
