Aqueous and Solvent Processing of Solder Mask Materials
Different polymer systems are used for aqueous and alkaline developable systems for solder masks．Full epoxy polymers as well as acrylated epoxy／epoxy resin hybrid based solder mask materials have been used in the PWB manufacturing for many years．There are two types of development processes used in the market which lnfluences the environmental impact of Waste and on the environment．There are rather big regional differences of using solvent or aqueous developing processes．The European market is dominated，by market share，by solvent developing process material types including full in．house recycling systems．Properties and performance of these formulated insulation materials are well．known and well established at OEM level．This paper outlines the differences between the two product groups in respect of chemistry,processes，performance and final propeaies．
