Hello Bob,
Some of low-end pcb fab shops still apply seal brite coating on single-side power pcb board. Is it a bit cost effective than new generation OSP?
What's the long-term reliability and ionic cleanness of seal brite coating compared with new generation OSP? Thank you.
Best Regards
Charming Chan

I would be surprised if this product is still available, especially in
t's original form. As others previously stated, it was rosin in solvent.
he problem with the original product is it required either solvent or
emi-aqueous cleaning after soldering. In today's world of no clean
luxes, this product would not work. Perhaps they have formulated a no
lean version.

blast from the past.
ealbrite was a Lonco product, a solution of rosin in solvent that was
ffectively a simple varnish. Air or oven dried. Worked OK.
Alpha Metals had equivalent products Alpha [2301 2302 etc] which aped it
easonably well. What happened when everything, including Enthone and
heir
roducts, became Cookson I don't know. Most likely these simple materials
ere let go in favour of Enthone's modern OSPs.
