Thanks for this reply - we're up against all the things you mention...

Yea, that seems pretty obvious to me as well but we have a customer that's not buying into running lead-free in conjunction with lead. They strongly believe that we need to install a dedicated lead-free SMT line inclusive of in-line wash system. Th

We use the OM-5100 and wash it with relatively good results. Just dont let it sit longer than a few days before wash. We've used Zestron AC200 and A-250 in a batch cleaner set to 140 wash temp for 8-10 min @ the recommended concentrations. We have h

Hi ! Thank's for your replies. I'm seeing you're very concerned about this subject. I think RoHS and WEEE arrive too soon. Not technological solution about whiskers and tin pest. RoHS implicates a lot of money for to implemente news process. We must

As we navigate through the CORVID-19 pandemic, many essential manufacturing facilities are still on line and operating. Some at reduced or modified schedules in following the guidelines to help reduce the spread of this virus. My question is in rega

Do you bond with Al or gold wire? What happens if the Ni is over 150 microinches? Thickness of nickel is one those things that we have not been consistent with. The industry seems to pretty much universally call for 100-200 microinches. Our old board

I don't have a plasma cleaner either. It will help a lot. Actually I don't clean at all. Our wirebond pads are far enough away so the flux residue does not get on the wirebond pads. That's what we think anyway. I am sure we have some degree of c

Hi, I curently have an interesting challenge. But I don't have all the knowledge to solve it. One of our boards is used in RF applications. We noticed that the No-Clean flux residue makes interferences in the RF signal. Removing the flux residue so

Canyou see this contamination? Is it solder beads, flux or something else? If flux, then more cleaning should help, either more time, more cycles through the cleaner, etc. If it is solder beads that are not melted to the rest of the solder, then s

First, we agree with Loco that your QFP is nonwetting, rather than dewetting. Your sceen-shots look like ol' timey SnPb paste recipes. Turn-up the heaterometer dial. Second, on nitrogen: * We kinda think your O2 needs to be around 100ppm with 99.99%
