Are you refering to reflow soldering or wave soldering? Brian, do you have any data to support that SAC305 is more reliable than Tin-Copper-Nickel? NEMI reccomended SAC type alloys for reflow and Tin-Copper for wave. See: http://circuitsassembly.

I am not a current user of PACE TF1500 however, I have evaluated it along with other systems before making a decision. Wasn't a good system for us. We could not achieve consistency / repeatable results from board to board. Basically, we found it t

Pad design - Standard IPC 20 pitch QFP Thermal pad design - Layout the thermal pad 0mm to 0.15mm larger per side (0mm to 0.30mm larger overall) than the exposed die pad on the package. �Larger than�, as opposed to the same size, is preferred. Obvio

The Juki 2060 can have both front and rear trolleys and you do not loose any feeder locations. My question was why can't the Assembleon put trolley on the rear? I recently visited a friend at a company that used a lot of Assembleon and compared run

I still have half of a 500 g jar of this paste left. I'm going to give it another shot, but my first experience was not so wonderful. Everything was great until we reflowed it. Our profile matched AIM's recommendation, as far as I can see. The ch

Sorry, I have not read the article. However, I do have five years experience constantly tweaking an AOI system that ran ONE product! The strength of the machine was solder inspection. The biggest problem was component color variation and shadowing

First of all, do not use kapton tape! It tends to cause a dewetting effect around the tape. A call to Humiseal will explain why. There's not really a blanket answer to your question.... Removing cured liquid mask can often result in a fillet ef

We manufacturer cleaning equipment (full disclosure) so, our answer may seem self-serving. The facts however are accurate and relevant so here I go� Changing from an OA (water soluble) flux to a no-clean flux makes sense. After all, even die-hard
