Hi All: We�ve got a problem here with opens on bottom side wave soldered SOT23s. Based on past experience and review of the SMTnet archives, I feel that our main problem is pad size. We have the same size pads for bottom side SOT23s as we have for

Does anybody knows any outside service for SIR testing. I am being question if my cleaning process is good enough and I don't have any ways of proofing it.

Well, another alternative is to use a water washable flux. If you insist on staying with a NC flux, use one that is probable. We prefer to probe solder, rather than copper.

Use Water soluble if you can, if not I would try the Indium SMQ NC paste, this residue stays soft. I would also change ICT probes to the "drill type". Russ

use water soluble solder paste is the cure for your problem. but if you insist of using NC change your pogo pins to pointed pins.

Hi, There are "Fluxbuster" or "Rotator" pins on the market - we had to use them a few years ago on a flexy board (with OSP). There is some info from one source at the following link: http://www.isiconnectors.com/mfrs/idi/idipr.htm#Rotator We got

Dears, I've a board with OSP surface finish,and I planned to print solder paste on the test pad for easy ICT, because the probe can't reach the OSP covered pad.But to my surprise,after reflow there's much flux residue on top of test pad(or solder) an
