Hello Ramon, This is a very common problem that usually can be overcome. Can you tell me the flux type you are using (manufacturer, and flux number)? Has your board vendor, or type of PCB's changed (are they entec coated - bare copper)? What is t

Dear all friend, I found problem of soldering bridging between SMT Chip terminal & Glue , but under the chip body. My process was double side SMT assembly with bottom side adhesive & heat curing, then wave soldering with water soluble flux (OS type)

It's a typical answer from a board fabricator - 'None of our other customers have these problems'. But, and correct me if I'm wrong, none of the other customers uses the same PCB's as you do! Your preheat-parameters looks OK - they should not be giv

Your safest bet is to manually remove the trays. The problem with what you want is that the machine does not know that it missed a part. It simply goes to the point you specify and tries to pick somthing up; if it doesn't pick up anything it believes

David Fish alerted me to this dialogue, after visiting my web site. I am one of the "anal" consultants that are trying to help people "learn from things that go wrong." I don't know where to start. Perhaps by asking you not to lump all of us toget

We had the same problem years ago when we started using a radial inserter. The inserter would dutyfully insert and clinch the leads. The problem in our case was the component body sealing to the fab, especially on electrolytics caps with a film jac

since you did not define what visual process you are inspecting with I will ask is this "grainy" appearance being detected with the naked eye only? Are you using magnification? if so, what power? Is this a SMT solder or through hole solder problem?

We don't actually leave the residue on the board, even though the Kester spec sheet says it is ok not to clean - we do spot hand cleaning with Safety Wash. Kester also said that there shouldn't be any problem with mixing RA with no-clean, although w

Dave, Ashok mentioned that the end termination of the component were dull and grey. I have had similar problems with Murata components exibiting the same characteristics on the end terminations. As it turns out, they have some exotic plating material

Erico:I can�t even imagine what this line looks like and what it has to do with the soldering problems without having a look at it. Also the restriction to touchup only is somewhat irritating to me. The only thing that I can think of is that in your
