What are some detection methods for touch button switch test? How do we do the details below to give you a detailed introduction?
Every product we use today needs to be processed, and then tested to be qualified before going out of the factory, so how about the main performance tests of the touch button switch? Let's learn about them together with the knitting.
1. Welding resistance test:
1. Weldability test:
Method: The welding feet were soaked into the tin pool about 2 mm deep, and the test temperature was about 230 5 C. The holding time was 3 0.5 seconds.
Result: More than 80% of the welded feet will be covered with tin.
2. Welding resistance test:
Method: The temperature of solder in the furnace is controlled at 260. 5 seconds, and 350. 30 seconds. The time is 3. 5 seconds, but the abnormal pressure on the welding foot can not be exerted.
Result: The light touch button switch has no distortion and can satisfy the electrical performance. The result of applying abnormal pressure is invalid.
2. Cold resistance test:
Method: Place it in a temperature environment of minus 20 3 for 4 days, then put it in a normal environment, and test it 30 minutes later.
Result: Contact resistance and insulation resistance are all within the standard range, and there is no sign that the performance of the switch is damaged.
3. High temperature resistance test:
Method: The product is stored for 2-3 minutes at 280 +30C, and the handle and resistance of the product are tested after heat dissipation. Result: Resistance, springback of acrylic force, shape, etc. showed no signs of damage. The performance of light touch button switch is still non-destructive, such as Junior Four, moisture resistance test:
Method: Place it in 40 + 2C90 - 95% RH environment for 4 days, then put it in normal environment, and test it 30 minutes later.
Result: Contact resistance and insulation resistance were all within the standard range, and there was no sign that the performance of the switch was damaged.
IV. Temperature Alternating Test
At different temperatures, the test was carried out after five cycles and then placed in normal environment for 30 minutes.
Several main performance tests of touch button switch are introduced here. Electric focus on button switch, micro switch and other switches. Friends in need can contact us.
