Question :The dripping board of IPX12 drier can accept 1000mm size, meaning that the length and width of the rain board are 1000mm. In such a big plate, why is the needle board spliced by 4 small needle plates?
Answer :The pinhole spacing of the IPX12 drier is 20*20mm, that is to say, such rain board has a little rainfall. A dripping rain board may not bear the weight of water and cause danger. So when we make dripping boards, we use 4 stitching plates to splice together. A safety shield is also made under the dripping board, which will not affect the test results while ensuring the safety of the tester.
