Thanks Dave, and yes we can leave the solder there in this instance. These panels, 12up, are NCMR from the customer. The customer is saying that after the panels have been reflowed 5 times! solder starts to accumulate under the mask. Get this, My sen

Home plate apertures are designed to reduce or eliminate solder balls that occur when placing a chip and reflow of the solder. This aperture type is usually desired when processing with a "no-clean" solder paste. The design of the aperture is usually

In the past, we have spoken [typed?] about controlling the temperature and humidity of our plants. And it's probably good to do that from solder process control, ESD danger reduction, and human factors stand-points. We are looking to lower our ener

Every time you see one of those �National Geographic� articles showing pictures of clothing sweatshops in developing countries, the girls are sitting at gray Juki sewing machines. Juki placement machines were branded and distributed in the Americas

Jose, I have seen this defect before. We called it re-reflow. We found the part was originally attached at SMT. Later on after seeing a heat cycle at the wave machine the leads would de-attach causing an open at In-Circuit Test. Resolution was t

Tuan - One of the reasons I suggested pre-tinning (aside from the negative effects of Gold on appearance and reliability) is the known slower wetting of Sn/Ag and Sn/Cu alloys as compared to Sn/Pb. If you don't have to be Lead-free, the high Lead

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
