KEMPEN, GERMANY – Peters and Atotech are developing and testing environmentally friendly technology in the field of inkjet solder masks. The aim of this cooperation is to provide a coordinated system of pre-treatment processes and inkjet solder resists.

Peters set up a new laboratory test facility to develop a fine-structured application of solder resists on PCBs by means of an inkjet method, while Atotech supplies the pre-treatment chemicals and advises Peters on the fine-tuning of the associated process.

"We are pleased to have Atotech at our side as a competent partner for the further development of our product. The challenge of this complex process is to coordinate the interaction between the surface treatment and the ink,” said Johannes Tekath, research and development, Peters.

"Peters is a market leader in high-tech PCB coatings. We find it particularly exciting we can support them in working on a perfectly matched inkjet solution that brings both economic and ecological benefits," added Christopher Seidemann, global product manager, Atotech.

Substrates to be coated with inkjet solder resists are pre-treated using Atotech's CupraEtch SR8000 method. In addition, Atotech has developed the InkPromotor T15 method that prevents low-viscosity coatings from uncontrolled bleeding.
