Elekonta Marek has opted for a Peters solder resist. The German manufacturer of high-tech boards counts on the advantages of the 2-pack solder resist from series Elpemer 2467. As Elekonta is a prototype manufacturer for the automotive industry the cooperation is of strategic importance to Peters.
The decision of the Baden-Wuerttemberg PCB company is in accordance with the conception of both companies with respect to a sustainable cooperation. “When selecting the coating system we took the specific requirements of the automotive industry into consideration,” says Ralf Schwartz, Managing Director of Peters. The material of choice is Elpemer GL 2467 SM-DG, edition 766.
One of the Elekonta Marek requirements to a solder resist for curtain coating was the introduction of a coating system which is easy to process, robust and aqueous-alkaline developable – one prerequisite after many years of applying a solvent developable coating. The Peters coating does not contain the problematic photoinitiators type 907 or 369.
The product has a very low exposure energy so that all options of direct imaging can be used. Not only high permanent temperature and thermal shock resistance are given but also high current capability under moisture. For Lars Presche, Managing Director of Elekonta Marek, the reliability of the Peters coating is decisive. “We have opted for this product as it complies with the increasing requirements within the e-mobility area.”
