You are going to have trouble meeting all of the visual requirements 
     with hot bar attach. It is a side effect of the attach method. I had 
     to have special visual requirements for it, and these were not in any 
     standard. Maybe there is something now. I do not know.

this message is being forwarded from a co-worker,

the solder joints that we are forming with our hot bar process are not meeting
the requirements of 'standard' workmanship criteria.  in particular, we have a
difficult time meeting 'heel fillet' requirements.  the defect is one of
'insufficient solder' at the heel fillet.  it isn't that there isn't any heel
fillet; it's just that it isn't as pronounced as the standards require.

question.-  are there solder joint standards specific to hot bar soldering?

thanks,
