The products offered for PWB reflect a detail knowledge
about processes and performance requirements in this competitive
DiaEtch 120 is an innerlayer etch
resist, developed to match the needs for high volume production
using the roller coating technique. The wide processing window in
all process steps ensures highest yield.
The product can be successfully processed with
non-proprietary chemistry. The low drying temperature required
allows to realize
maximum throuput in all roller coating/drying systems.
102 is an innovative specialty. The product offers secure protection
of plated through-holes (100%) and vias in inner- and multilayer
constructions for thin and flexible boards up to thickness'
of 250 µm
(10 mil). This is accomplished using dip-coating. This photoresist
application is recognized as an „enabling technology“ by
