John,
Avoid at all costs.  Every time a human takes a soldering iron to a board you run the risk of decreasing the reliability of the finished product.  Rework should never be a "standard process step after smt".  This does not mean it never happens, but not every board, every day.

Subject: [TN] Touchup - We don't need no stinkin' touchup! Or do we?


Greetings all,

I have moved on from my old life in the fabrication business to learn some
new things in the contract manufacturing sector.  My first question to the
group in this new role is on the subject of touch-up as a standard process
step after smt placement and reflow.  Does everyone do this or can it be
eliminated by process control during placement and reflow?  I personally
don't much care for non-value added processes but was just wondering what
the general feeling out there was.

Regards
John Parsons
