We call this the "orange stick test", but who's coloring? In preforming the test, you're supposed to use a light touch. Unfortunately, it's difficult to calibrate a "light touch." So, operators often end-up using too much force when probing or usi

Are there any write-ups anywhere? My boss wants to show a customer a write-up. I"m checking IPC specs but havn't found anything. I think almost everyone does it but is not a published standard test. I hope some organization has written it up as a st

I have always been nervous with this process. I fear that the "good joints" may become fractured without coming loose. I am a proponent of this to verify a profile or something to see the strength but then we always reflow the affected joint afterw

Obviously, designing energy efficient products is good for the environment, but does it cost more? If so, how do I justify these costs in a competitive marketplace?

Today the line experienced the white gloves turns green at the point of contact when holding fresh board that came out from wave soldering. Was that the effect of inproper solder mask curing at PCB house during fabrications ? For a proper cured solde

Thanx for the feedback. The solder mask is PSR-4000 ( need to confirm this - not too sure ). If the board got in touch with the solder bath, for the contact time of 3 - 6 secs, this should not be the case for proper curing process right ?. thanx ag

Sounds like the mask wasn't properly cured. What kind of solder mask is it? We use a photoimageable mask on our boards. The secondary cure is ~ 90 minutes @ 150�C. One of the cured mask tests is solder bath resistance where it has to resist degra
