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.
