When we detect whether the mobile phone shrapnel is qualified, we should first check whether the appearance of the mobile phone shrapnel is dirty, scratched, crushed, and whether the middle point is deviated.
Then the load tester is used to test whether the strength and springback of the shrapnel are within the specified tolerance range, and whether the stroke and height of the shrapnel are within the specified tolerance range. Then the life tester is used to test whether the life of the mobile phone antenna shrapnel meets the requirements of the product.
