Why is it difficult to tin the High frequency PCB
Why are some High frequency PCB pads not easy to be tinned? Here, we will analyze the possible reasons for you.
The first reason is: we need to consider whether it is a customer design problem, and we need to check whether there is a connection between the pad and the copper sheet that will cause insufficient heating of the pad.
The second reason is: whether there is a problem with customer operation. If the welding method is not correct, it will affect the insufficient heating power, insufficient temperature, and insufficient contact time.
The third reason is: the problem of improper storage.
1. Under normal circumstances, the sprayed tin surface will be completely oxidized in about a week or even shorter.
2. OSP surface treatment process can be stored for about 3 months
3. Long-term preservation of immersion gold plate
