Couple of questions. 1) Are we talking alumina substrates as the ceramic material? 2) Are we co-firing gold as the conductors on the substrate surface? 3) In other words, is this a hybrid thick film circuit? 4) If so, how large or

We've all been soldering Pb free parts for a couple decades. All your surface mount capacitors have probably had a Sn finish for years. Whenever one of our parts with a SnPb finish converts for Pb free we have the manufacturing site do a small buil

What version of sw are you running? There are some new features in 2.7.7 and earlier that may be of benefit to you. With chip caps you are testing for presense/absense. The gain/offset feature can be used to give you better contrast between the pa

Thinner: Flux thinner, NOT paint thinner We kept a spare stone in thinner in inventory. We cut PVC pipe to size, cap in one end, screw thread on the other, stone inside, filled with flux thinner and covered with a screw cap. I don't remember who we

Hi there Gary, Your solder ball problem is very similar the problem I experienced, but I was using a water soluble paste at the time. It started by inspectors telling me that they were seeing cold solder on some SIMM's that we had built regularly. W

Re: wave soldering surface mount tantalum and ceramic capacitors

Electronics Forum | Fri Feb 05 09:39:58 EST 1999 | Dave F

Can anyone help me with the pros and cons of trying to wave solder tantalum and large (1812) ceramic capacitors. I do know that one may see fractures on larger cermaic caps, but have not seen much on the tantalums. Any insight as to what proble
