All,
Or a better question, how does it affect the operators in the lamination or reflow areas?  As Br eliminates O2 are they asphixiated or worse?

All,

As a simple MLB guy, my concerns are focused on laminate integrity,
primarily. Even as brominated resin systems obviously have been around for
years - with one simple function - to put out the fires or is it prevent
them. No, put them out. Is that protection or prevention? No, protection.

If the bromies "rise to the surface" during bake and process cycles, what
does this do to laminate integrity over may thermal excersions for extended
periods. Most laminate suppliers have improved their resin systems
constinually over the years and most provide what I need and it seems to be
getting better even with an element essentially once though to be inert in
the x linking phase. Now it is somewhat a part of it as it works much better
now with the other resin system elements.

So, again as one person reported, if the bromines rise to the "surface" in
about 15 seconds, how does this impact quality and long term reliability.
Also, what's an alternative to flame retardant materials, besides polyimide
(not a good option for many)?
