Multilayer Rigid PCB Drilling
Drilling takes up the longest time of the whole PCB process and around 90 percent of it is performed by mechanical CNC drilling machines. Which machine sits in that station decides both the final product quality and the cost per panel.

Industry Pain Points
- Higher density smaller hole size and more layers push the hole diameter below what an older machine can hold
- Hole location accuracy that drifts outside the CPK window the customer audits
- Drilling time dominating the process cycle so the whole plant waits on one station
- Tool changes and tool checks stopping the machine between hole size groups
- A spindle speed range that covers small diameters without giving up hole quality
- Tool capacity large enough to run a mixed hole size programme without operator intervention
- Broken tool detection that reacts before a whole stack is scrapped
- A machine base that does not move with temperature or vibration
Typical Application Scenarios
Small diameter through holes
D2X D3X and D4X drill from φ0.15mm to φ6.35mm at 160-200krpm with drilling accuracy of ±1mil.
Mixed hole size programmes
220pcs tool capacity with automatic tool length and diameter check lets one programme run through many diameters.
High panel throughput
D3X and D4X reach 80m/min on the XY axes which is the practical route to shortening the drilling cycle.
Stack drilling
Pile height is one of the technics parameters listed as affecting hole location accuracy and is set against the material and the hole diameter.

Solution Process
Confirm the hole map
Send the drill file the smallest diameter the panel format and the stack you plan to run.
Match the series
Ball screw drive on D1X and D2X or linear motor drive on D3X and D4X depending on the feed rate you need.
Set the tooling
Drill bit specification pressure foot and vacuum pressure are confirmed together with the machine.
Install and hand over
Installation training and the daily weekly and monthly maintenance schedule are handed over with the machine.

Multilayer Rigid PCB Drilling FAQ
What drilling accuracy can I expect
Drilling accuracy is ±1mil on the D2X D3X and D4X series with positioning accuracy of ±0.01mm and repeatability of ±0.005mm.
How is hole location accuracy actually controlled
Equipment condition technics parameters tool status and operator skill are the four groups of factors. Regular check and maintenance sits at the top of that list.
What is CPK and what value should I hold
CPK is the complex process capability index used to evaluate manufacturing capability. A value of 1.33 or above means production capability is steady and matches the requirement.
Which series should a high layer count shop choose
The series is chosen by feed rate and hole size. For the smallest diameters and the fastest cycles the linear motor driven D3X and D4X are the correct starting point.
