We are having difficulty with bridging on a 2x50 pin 0.050" fine pitch connector using our selective soldering machine. It usually bridges at the end of the row, but sometimes it bridges all the pins together as it drags across (solid bridging). I

Finally got using the calculator guys, (used another server connection). Not sure about the data that is entered for 'solder joint analysis', any helpful hints? To touch on the subject of Scots people being 'cheap', I cant understand these rumours, w

I have seen this before, our problem was palladium termination of this component. We could not change suppliers so we use a "reverse homeplate" stencil design to put the majority of paste directly underneath the solder terminations of the component

We have talked about using mircoscopes and laser thingies for measuring paste height on SMTnet previously. [Fine SMTnet Archives might give background.] Some people use a 0603 chip cap as a standard. I'm not sure how stencil height relates. Paste

On a related note, I'm wondering if any of the newer devices have any way to factor in paste not releasing from the corners, or for that matter, radiused, oval, or round apertures. We have an LSMII, and all it does it let you draw a rectangle around

Mark - The Waverider is a great tool. It will let you know what's going on with the machine itself - contact time in the wave, parallelism of the wave, temp, and a relative idea of whats happening in the preheat section, and conveyor speed. We hav

1. Check printing accuracy. 2. Check placement accuracy. 3. Your components should be kept in a good environment to prevent oxidation of terminations. 4. Pads pattern should be designed according to standards. If 1.2. are okay, you should suspect 3

Steve: You make sense, but I don�t see where someone that's getting fitted for a cross is in much of a bargaining position. Oh, and you MUST charge full market 2� rates for your thoughts. We�ll have no submarket price offerings. Although, the Fai

We currently use Kapton tape to cover a display. The only real purpose for this tape is to cosmetically protect it thoughout the process. The display gets hand soldered and washed, so the idea of the tape being high temperture isn't a factor. Becaus

I 100% agree with Wolfgang. No matter how many in line or off line inspection gadgets, zillion $ printers, and top of line stencils you use, bottom line is a properly trained machine operator who gives a rat about his/her job that makes the differenc
