The Range of Services for reliable Connections

We specialise in the production of double-sided through hole plated PCBs and multilayer PCBs in serial production with up to 12 layers and prototypes with up to 20 layers in different copper thicknesses.

With our motivated and qualified team of 85 employees, we reach a yearly manufacturing capacity of 110,000 sqm. Due to the high level of automation in the manufacturing process we are also able to produce high volumes at competitve prices besides samples in express service.

We offer our customers a wide range of services in the field of innovative PCB technology.

preferable 35 / 70 / 105 µm
max. possible 140 µm
additionally 18 / 50 µm possible

PCB-thicknesses

0.80 mm up to 2.40 mm

Number of layers

2 - 20 layers

PBCs are constructed in such a way that there is an optimum utilisation of the production blank, i.e. PCBs are rotated and may therefore have different fill and machine directions.

With multilayer PCBs ≥ 8 layers, the PBCs are no longer rotated in the production blank, because otherwise the layer offset becomes too high.

The fill direction is always the long side of the blank, the machine direction always the short side.

Smallest PCB in milled form: approx. 3 cm x 5 cm

Drill diameter

0.10 mm to 6.5 mm drilled; bigger ones are milled; drill diameter depends on the PCB thickness
presumably available from October 2006: pocket hole drills and burried via´s

Layout structures

Track width > 100 µm
Track space > 100 µm

Width and space depend on the base copper thickness.

Tests

All PCBs are tested pursuant IPC-TM-650. In case of samples, a first sample test report in accordance with VDA 6.1 is attached. "The customer decides on content and complexity of the first sample test report.“
