Hi All,
Following the unexpected discontinuation of our current favourite
surface finish, an OSP that went by the name MCoat, we need to select a
replacement solution or process.
To satisfy some of our smaller customers we would ideally like to
maintain the 5+ year shelf life that the MCoat finish easily secured.
Amazingly from a small PCB manufacturer's point of view it withstood
multiple solder passes, was compatible with IMS and even worked
selectively on boards with hard gold connectors. Not forgetting very
environmentally friendly both energy wise and chemically, to date our
current 100 litre working solution has processed an impressive 35,000+
sq. ft of laminate.
Does anyone have any data or know of any papers that might help, I'm
particularly interested in solderability in combination with an extended
shelf life.
Many thanks for your help in advance.
