Several main performance tests of touch button switch indicate:
1. Soldering resistance test:
1. Weldability test:
Method: The welding feet were soaked in the tin pool about 2 mm deep, the test temperature was about 230
Results: over 80% of the weld foot will be covered by tin.
2. Soldering resistance test:
Mode: The temperature of soldering furnace is controlled at 260
The temperature is controlled at 350
Results: the touch button switch has no deformation and can meet the electrical performance. The application of abnormal pressure is invalid.
Two. Cold tolerance test:
Method: Place it in a temperature environment of minus 20 65507
Results: The contact resistance and insulation resistance were within the standard range, and there was no sign of switch performance damage.
Three. High temperature resistance test:
Method: The product is stored at 280
Results: resistance, acrylic rebound, shape and so on, all showed no signs of damage. Touch button switch performance is still undamaged.
Four. Humidity test:
METHODS: Place it in 90-95% RH environment at 40 6550
Results: The contact resistance and insulation resistance were within the standard range, and there was no sign of switch performance damage.
Five. Temperature alternating test
In different temperature environment, cycle five times, and then placed in the normal environment for 30 minutes after the test.
The above is the test method of touch button switch, please know more about it.
