How to check the air tightness of relay?

The relays used on the PCB board are small in size and have crowded internal space, and most of them use welding technology to connect to the PCB board.If traditional immersion is used,

Difficult to detect with the naked eye.At this time, you need to use HairisAir tightness testing equipment！

First, connect the Hairis air tightness detector to the corresponding mold.Set the parameters of the instrument pressure value and leakage value, and put the relay into the mold.

The final instrument test results may appear in the following situations:

  1.The pressure value is low and the leakage value is up to standard.———&-The relay has a big leak and is a defective product with a big leak.

  2.The pressure value is up to standard, but the leakage value is on the high side.———&-The relay has very small leakage and is a defective product with slight leakage.

  3.The pressure value and leakage value both meet the standards.———&-The relay has no leakage and reaches the IPX7 waterproof level standard. It is a good product.

What principle does Hairis air tightness testing equipment use to detect the sealing function of relays?
    The principle of relay seal detection is to use gas to simulate the underwater environment of the relay.The relay is sealed with a mold and then filled with a certain amount of gas.if there is

If there is a leak, the air pressure will change, and then the leakage value will be obtained through a series of complex calculations by the Hairis air tightness detector. According to the leakage value, the relay can be determined.

The sealing performance of the relay can be known based on the sealing performance and IP waterproof level.

The detection accuracy of Hairis air tightness tester is as high as 0.1PA, and the detection pressure range ranges from -80 to 1000kpa.Very suitable for waterproof sealing test of circuit breaker.
