Hello,
I have a couple of questions concerning PGA at the wave soldering operation.
- If I want to solder only the PGA (located in the centre of the board) and
avoid the rest of the board, what can I use to efficiently cover these areas
on the solder side (something that can be used in a production mode) ?
- There are tiny SMT components located in the perimeter set by the inner
pins of the PGA, on the solder side. Am I the only one who experienced the
problem of having these small components falling into the solder bath even
though they were glued ? Is mold seal the best solution ?
- Is it possible that the heat needed to solder the PGA be too much for
these small components (1206, 0805, etc.) ? If so, how do I protect them ?
As always, your advices will be quite helpful. Thank you.
