Hi John, Thanks to your reply, just one question is it possible that the solder paste ( flux material )applied to the pads cause the non-wet. regards Chris

Chris: You can have more than "one question!!!" Anyhow, yes crappy solder paste can cause non-wetting, but before you go there understand why the paste is wetting some surfaces, but not others. Ta Dave F

Can you provide me with non water base chemical ( 1 part only) for cleaning non water soluble flux and earth friendly. I would appreciate very much if you can also give me contact info. Arman

Sorry for the miss-understanding - there are at least 2 types of MSD cards - reversible & non reversible. We use the non-reversible type. Once exposed they record the max humidity through a one way chemical reaction.

Tell your board house/customers you want "non-smobc". hich stands for non-solder maske over bare copper. MPMs love exposed fids in just about any finish. You can always use pads on an MPM too.

Shocker, You truly live up to your name with those "sexist" remarks! Are you Islamic? "Mumtaz" is an Indian/Arab name. As for me, my wife converted me to become non-muslim...probably the non-practicing muslim here in Riyadh...

Distributors and dealers can ship non-ROHS parts forever. Assemblers can not ship non-ROHS products to Euroland after July 1 and other counties [Japan, Korea, China, California, etc] after their cutoff dates.

if you did not take PCB temp over about 245 C you got no probs buddy. just non compliance most likely. Fiberglass and copper, not much can happen there Russ

Distilled water normally removes ions as well as dissolved solids (non-volatiles). Deionized water has been stipped of ionic species, but non-ionic organics are left behind.
