Automated CNC drilling and milling machine

Besides high accuracy positioning (better than 9µm) and a quality and economical drilling of the PCB require special materials such as IMS (metal core PCBs for heat management) an optional minimum quantity lubrication. It ensures a low burr cut edge with high productivity.

Type:	A-MX1-300-DH-CCD
Made in	2015
Technology:	Programmable minimum quantity lubrication Tool chain for more than 2800 tools Vacuum Adapter for vibration free machining Tool measurement by laser Speed up to 300,000 rpm for drill diameters from 0.1mm Highly accurate depth drilling and routing via contact Linear motors for fast and precise movements High-precision depth machining by contact drilling and contact milling Optimized Registration using CCD camera

Scoring machine

The scoring machine made by the leading manufacturer LHMT permits simultaneous scoring of circuit boards on both sides, both with standard scoring as well as with jump scoring.

Made by:	LHMT
Type:	LHMT Scoring System
Made in	2008
Technology:	Simultaneous scoring of circuit boards on both sides, both with standard scoring as well as with jump scoring. Tool is aligned via so-called camera targets: this increases the precision of the scoring process Scoring of very thin circuit boards down to 0.5 mm Tolerance of residual material is 50 µm Equipped with a data matrix code reader After reading in the sequence programme, works fully automatically

Grinding Machine

After plugging process, the surface of the PCB panel is polished planar. This is done with the highest precision, uniformity and low final surface roughness.

Made by:	MASS GmbH
Type:	SV 100 WV
Made in	2013
Technology:	Single sided manual grinding of printed circuit boards Linear bearings on all axes Setting accuracy of the Z-axis 0,22ìm Automatic Pressure Control Vacuum to fix the boards on the table Various Grinding wheels for standard grinding and lapping
