CNC Drilling Machine for PCB hole precision analysis
As we know, a good hole location accuracy is always convenient for following process and customer use.So in some extent, it even makes up the drawback of following process management and control. But the picky on accuracy may cause lower work efficiency, hurt company and staff members’ interests.
Therefore we then quote a concept “CPK“(Complex Process Capability Index). It’s the indicator to evaluate modern enterprise manufacturing capability. Normally we require CPK≥1.33, this means production capability is steady and match the requirement. If CPK≥1.66, this means production capability is over requirement, need to adjust input and output.
We list some elements that may affect hole location accuracy.
The first element is equipment.For this reason,regular check and maintenance is necessary,because you can detect and wipe out the problems as early as possible which is vital for keeping work accuracy.
The second element is technics parameters. Therefore you should analysis the below factors:
1.pile height 2.rotation speed 3.feed in and withdraw 4.working life 5.backup board material and hardness 6. cover board material and hardness 7.workpiece material and hardness.
The third element is specific tool status, for example tool grinding and control, pressure foot status, pin situation and vacuum pressure
The last one is operators skill level. in this case,it is also very important part in the whole process.
In brief,drilling precision is a very sophisticated and highly technological process.So we rely on scientific, reasonable, precisely, correct thoughts to guide us, never just behave by feelings.
