The main test touch switch resistance welding, resistance to cold, heat resistance and moisture resistance
A, soldering resistance test:
1, solderability test:
Method: the welding feet into the tin bath is about 2mm deep, the test temperature is about **0 ± 5 ℃, holding time was 3 ± 0.5 seconds.
Results: the bubble leg section *0% above will be covered tin.
2, soldering resistance test:
Methods: reflow solder temperature control in 5 ℃ at **0 ±, a furnace welding is maintained in time 5 ± 1 second to (substrate)
Temperature control at **0 ± *0 ℃ when hand soldering, time was 3 ± 0.5 seconds but not on the welding foot applied pressure.
Results: the switch without deformation, able to meet the electrical properties. Applying the results of abnormal pressure.
Two, cold resistant test:
Methods: for 4 days at - *0 ± 3 ℃ temperature environment, and then placed in a normal environment, *0 minutes after the test.
Results: the contact resistance, insulation resistance is in the standard range, without any signs of damage to the switch performance.
Three, high temperature resistance test:
Methods: the temperature at **0 ± *0 ℃ environment, product for 2 - 3 minutes out, to be cooling after the handle, resistance test.
Results: the resistance, resilience, chocolate shape; all without any signs of damage display. Still intact after switch performance
Four, moisture resistance test:
Methods: 4 days at *0 ± 2 ℃ *0 *5%RH environment, and then placed in a normal environment, *0 minutes after the test.
Results: insulation resistance is in the standard range, contact resistance, and without any signs of damage to the switch performance.
Five, the temperature cycling test
In different temperature environment, test after *0 minutes after five cycles and then placed in a normal environment.
