VARIOPRINT Converts to Peters Solder Resist

Reading time ( words)

In the course of a quality campaign, VARIOPRINT AG relies on the ELPEPCB® Elpemer® AS 2467 solder resist system. The Swiss company will use this solder resist in the future for a large part of their printed circuit board types. For this purpose, the Peters ink system has successfully passed all reliability tests, including those specified by the international standard IPC SM 840 E "Qualification and Performance Specification of Permanent Solder Masks." The reason for VARIOPRINT's campaign is advancing miniaturisation in the electronics industry which has led to more sophisticated PCB constructions and designs.

Leading PCB manufacturers such as VARIOPRINT are concerned with the risk of the PCB being damaged during soldering in assembly production owing to the higher temperature load. By choosing the solder resist system from Peters, the Swiss company located in the canton of Appenzell Ausserrhoden south of Lake Constance, can meet the requirements for production processes and materials. Particularly with regard to the base material, VARIOPRINT is able to provide, thanks to the Peters expertise, higher Tg values and a better dimensional stability of the PCBs. "Our process engineers defined very stringent specifications for the manufacturers, in view of guaranteeing the highest possible product quality to our customers in the future," says VARIOPRINT sales engineer Sascha Faust

VARIOPRINT is convinced that the new ink from Peters does not only feature a better environmental compatibility, but also a higher grain-fineness of pigments and fillers and a higher performance in exposure. The VARIOPRINT research team has established that the ELPEPCB® Elpemer® AS 2467 system made in Kempen ensures a better structuring of the ink on the PCB, especially in ultra-fine conductor applications. In addition, this creates a more homogeneous surface structure. Combined with modern production processes, the printed circuit board from VARIOPRINT coated with Peters ink is setting standards. Sascha Faust: "This is the only way to ensure that our PCBs will be of highest possible quality for the next PCB generation and the one after that."
Solder Resist is Eco-friendly
"The fact that VARIOPRINT, a globally recognised PCB producer, has opted for our solder resist is proof of confidence for us, and an incentive to offer ourselves to other manufacturers," says Daniel Langenstein, managing director of Peters Schweiz GmbH, referring to other companies of the industry that have recently switched over to this or similar Peters products for the reason of their quality advantage and the eco seal. This is because the eco-friendly products from the Lower Rhine do not contain the problematic photoinitiators type 907 or 369 that the authorities have classified as a hazard to health and environment.
