Technical Support

Technical consulting services to optimize your production processes

Global Technology provides qualified technical support for the drilling and routing departments of printed circuit board (PCB) manufacturers, aiming to improve efficiency, reduce defects, and ensure production continuity.

DRILLING

The number of hits a drill can perform depends on several factors, including:

  • the diameter of the drill bit,

  • whether a new or reground drill is used,

  • the type of material being drilled.

The available parameters are calculated for new drill bits, considering a cutting speed of 150 m/min.

How to calculate the number of hits

To correctly determine the number of hits:
✅ Take the value corresponding to the drill bit diameter and the type of material to be drilled.
✅ Convert this value to millimeters.
✅ Divide it by the thickness of the material to be drilled.

Note: Reground drill bits should perform approximately 20% fewer hits than new drill bits to maintain drilling quality and prevent defect formation.

Technical training and documentation available

Global Technology offers dedicated technical documentation to support technicians and operators in drilling and routing departments:

✅ “Drilling” and “Mechanical Drilling” Files
These training materials are ideal for personnel being introduced to the PCB drilling department for the first time. The documents include:
