German supplier of coatings for electronics, Peters, is now offering coloured versions of its 2467 Elpemer solder resists. These products are available in red, black, white and blue. According to the company, the colours are most effective when PCBs are part of the appearance or design of a device, for example, when the circuit board is visible behind Plexiglas.
The 2-component solder resists are easy to apply and “meet the highest quality requirements,” Peters stated in a press release. It also confirmed that these products no longer contain the photoinitiators type 907 or 369, listed as Substances of Very High Concern (SVHC) by the European Chemical Agency (ECHA).
The company added that the circuit printing coatings are robust when subjected to temperature and humidity, resistant to yellowing, highly current-resistant, easy to apply by spray or screen printing, and halogen-free. The colours are intense and have a high opacity.
“The coloured Elpemer solder resists from the Kempen-based chemical company‘s research department also exclusively claim the quality seal of digital and direct exposure permitting a high level of imaging accuracy and low clearance, for example around drill holes,” the company stated.
Peters says its resists are utilised in various fields including the automotive, aerospace, consumer and industrial electronics, lighting electronics, medical technology, communication electronics and solar technology sectors. The Elpemer ink system can be tailored to suit specific requirements.
