<< Hi folks,
I am looking for inputs on a long-standing problem encountered in our shop:
Bottom-side
parts (passives) falling off in the Wave...where the only remnants of the
part is a flattened glue
dot of proper diameter and volume, and sometimes flux residue (from the
wave).
I suspect there is some incompatibility between one of our pastes and the
glue. Our shop
uses two types of paste and one type of glue. After some experimenting, I am
seeing a
STRONG correlation that suggests one paste type is not suited to the glue.
Short of listing the specific materials used and getting myself in trouble,
is there anyone who
has encountered the problem I am talking about? What was the cause and how
did you
resolve it?
If you want more specifics, please call me at 509-921-4311.
Thanks,
Earl & Marc >>
Hi ya Earl (and Marc)!
Hey pardner! Where were ya' for the expo? Was lookin' forward to seeing if
you're uglier than me (GRIN) But from the sounds of things, looks like you're
kinda' up to your keester in alligators...probably couldn't afford the time
away huh?
Anyways, are the parts that are falling off all the same part? Or are they
all different ones? If they're all the same, the time that something like that
happened to me was because of the mold release compound they used when making
the tape for the components, got all over the caps we were using and the glue
didn't wanna stick to em'... ...got components from a different vendor and
everything was okie-dokie after that. But knowing murphy, it ain't gonna be
that simple for you...but just maybe it might.
C-ya L8'er 'gator!
