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 0.3 mm Tolerance of residual material is 50 µm Equipped with a data matrix code reader After reading in the sequence programme, works fully automatically

Automated CNC drilling and milling machines

Drilled hole diameters are getting smaller and smaller. The main challenges are to position precisely and drill quickly.

Made by:	Ernst Lenz Maschinenbau GmbH
Type:	4 off DLG 615-1-AL:
Made in	2002, 2005, 2007, 2009
Technology:	Tool measurement by laser Two separate spindles for special requirements: Drill spindle with air bearing for small holes as well as spindle with ball-bearing for milling and drilling larger holes. Speeds up to 300,000 rpm for drill diameters from 0.1 mm Linear motors for quick and precise movements Max. 9 µm drill position error Very precise drilling depth due to mechanical drilling (as opposed to laser) Laser corrected drilling/milling using CCD camera

Multilayer press

Internal layers, prepregs and copper films are pressed together to form a multilayer board. For an SBU (Sequential Build Up) multilayer board, this and many other processes are carried out several times.

Made by:	HML-Multilayerpressen
Type:	HML MP-2 VK
Made in	2004
Technology:	2 levels In each of the 2 levels, up to 12 standard multilayer boards can be pressed Max. pressure 500kN Max. pressing temperature 310°C PLC computer for various temperature profiles Vacuum press chamber
