For flexible electronic circuit carriers, Elpemer solder resist SD 2463 FLEX-HF is a suitable product for all fields of application. It reliably covers those areas of a printed circuit board that are not to accept solder during subsequent soldering processes. It also exhibits high hardness and scratch resistance after final curing, which protects the PCB from mechanical damage during further handling.
Elpemer solder resist SD 2463 FLEX-HF is used in the automotive, aerospace, sensor and medical technology sectors. Here, its flexibility makes it particularly suitable for the tiny bending diameters on flexible printed circuit boards for hearing aids. The highly flexible two-component solder resist is also photo-structurable and shows exceptional resistance in chemical and electroplating nickel/gold and chemical tin baths as well as OSP processes. In addition, it is free of toxic photoinitiators.
