Drilling is an important process in PCB process. It looks simple, but actually it is very critical process.
and many reasons can cause the defective drilling, machine,human,drill bit, backup board,entry etc....
Today,we will Analysis the factors cause the burr
Problem |
Reason |
solutions |
|---|---|---|
| burr | Parameter seeting error | Seeting the correct parameters according to drill bit |
| burr | The drill bit is badly worn | control the drilling bit grinding times ,normally drill bits don't grinding |
| burr | density of the backup board problemtest | Test the density of the backup board.use high density backup board |
| burr |
There are sundries between the board |
When nailing board, clean the debris between the board |
| burr | The base plate bending | The plate should be pressed |
| burr | Without entry |
The entry is for protection and guide drilling. Therefore, when drilling, aluminum entry must be added |
| burr | Special plate material | When setting the parameters of drilling special plate, the parameters should be selected according to the quality, and the feed should not be too fast |
From this form ,we know you should chose the suitable drill bit, backup board, Al entry and use the right way to make sure
your drilling preocess running smoothly .
