For Peters, the new Reflow 1.8. machine from Seho is an investment in the future. Like its predecessor, this machine is used in the laboratory for testing high-quality solder resist. Before the coatings are entrusted to the customers, Peters subjects them to a thermal soldering simulation.

Substrates and circuit boards coated with Peters coatings pass through the inner workings of the machine via a conveyor belt. "There, the circuit boards experience temperature stress," reports Jonas Sutmann. Together with his colleague Michael Contzen, the coatings lab technician is responsible for the machine at Peters. "If our coatings survive this test under extreme temperature stress undamaged, then the industrial customer can be sure that they are also resistant, robust and permanently protect the respective circuit board in his context," reports the 26-year-old from Oberhausen. Using a total of ten emitters on two levels, the coated part can be heated to a maximum of 320° Celsius
in the new reflow system. "If the paint does not show any cracks or color changes after the heat bath in the in-house soldering system, a major hurdle in the development of new special paint systems for electronics has been overcome." For the customer, this ensures that the high demands placed on the paint systems from Peters are met at all times.

The machine is therefore an important building block in the development of solder resist technology. Peters is a leader in this field. "Our white soldermask systems from the ELPEPCB product group are used in many LED lamps," reports Detlef Paschke, Head of Technical Service at Peters. By deciding to purchase the soldering system from Seho, the Lower Rhine-based full-range supplier of coating materials for electronics has once again invested heavily in the Kempen-based family business. Not only in-house research and development, but also the area of quality assurance is advancing into new dimensions directly adapted to the customer with this follow-up machine. "This plant is indeed a further development of extraordinary value for our research and development," emphasizes Detlef Paschke, who has been with Peters for 27 years. The investment in the reflow system was consistent and future-oriented," says the 54-year-old from Willich. In the Peters laboratory, the 900-kilogram Seho machine, measuring 3.20 by 1.25 by 1.60 meters, is already a hunk in terms of length, height and width. "Nevertheless, our supplier Seho has built the system in such a way that it takes up around half the space than in everyday industrial production," says Jonas Sutmann, who is responsible for the machine.
