It's been many years since I have dealt with Sealbrite. When I did see 
Sealbrite in use, it was on single sided and some simple double sided 
boards, what we used to refer to as "punch and crunch". This was the 
solvent based system. It was a messy process, but effective and VERY LOW 
cost. The principle was the rosin was activated by heat and aided the 
soldering process. As I recall this process was not compatible with 
aqueous (organic acid) flux. The last time I saw it in use, no clean 
fluxes hadn't even been introduced to the market. Without knowing what 
other components are contained in the current Sealbrite, it would be 
difficult to predict what the effect would be on long term reliability.

I would bet the current version of Sealbrite is an aqueous system if it is 
still in use today. I contacted a friend at Enthone and he didn't have any 
info on this product. I'm not sure who is selling it now.

Re: [TN] Someone knows SEAL BRITE COATING?






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.

Hello All, 
Does anyone help input something about surface finish SEAL BRITE COATING? 

ot a talk with pcb fab shop today and I was told that there was SEAL 
RITE
OATING available for pcb surface treatment. I know nothing about such
urface finish and I'm quite curious. Thank you.
Best Regards
