Based on work I have been doing recently the most common reasons for component loss is board flexture and vibration on the reflow process. If parts do not reflow then weight is not an issue. There is a video on double sided reflow and PIHR from the S

| We have a double sided pcb that is surface mount on both sides. Now a Through Hole connector has been added. Appart from hand soldering does anyone have info. on reflow soldering the part. The connector is 0.1mm pitch, square legs. | 1) Do you need

What??? You don�t have enough things to monitor? The origin of some profiles is mysterious. It�s probably good to try to understand such mysteries. Certainly, the important determinants in the design of your reflow profile are: * Paste you�ve sel

Several points are: * There�s quite a bit of background on IMC in the fine SMTnet Archives. I�ll try not to duplicate it. * If you have a smooth and well-formed solder connection using fairly common materials, you assuredly will have IMC. Any evide

I used to love tweaking. I tweaked and tweaked until I got a master degree in tweaking. But than I had to teach others how to program a board and avoid tweaking. After all it does not go quite conform with ISO and other quality approaches. I investig

Selective soldering machines are a good way to "finish automation", if the design of the PCB is conducive to the application with just a few components to solder. Your points are good. A decision matrix for selecting a machine might also include:

Huh, what, geez. Wazza time Jimbo? Call me a cab. Why is this gentleman retroflecting? Why would anyone make an articulatory gesture by turning the tip of the tongue back against the roof of the mouth? I don't know what this is a bout, but I can a

I think this licensing thing was a poor decision to begin with. I can understand the reasoning for GenRad to issue a software license, to protect their product against cloning. Why Universal followed could have been caused by the take over and the

First of all, my Customers can be described as a real "Jack-Ass" or at least the SQE does. They don't treat us as their partners OR more like "do what I said...When I started to use solder paste you probably weren't borned yet and/or probably still o
