Hi
We are having a problem with solder balls forming around
and in mounting holes that have been spot masked. The
problem seems to have surfaced after upgrading our Hollis
wave machine to use an Electrovert Lambda Wave Solder pot.
Other than the Solder balls forming, soldering quality is
very good.
Any Suggestions would be appreciated.
Flux - RMA thinned to Manufacturer's recommendations.
Spot Mask - Tech Spray Water Washable
Solder Temperature(SN63) - 500F
Top Board Temp before solder pot - 200F
Thanks
Virgil
