Hi chs, What type of QFN or MLF package are we talking about? Assuming there is a middle thermal pad? Body Size & no. of terminals & pitch? What about your statement: "This package is so sensitive to any external force". Can you please explain what y

Hi, I'm a final year student of Electronics Engineering and I'm gonna start my final year project about Pick and place system. I've seen the Siemens Siplace pick and place machine and wondering how does the tape feeder know when to feed forward the

"...but does the Quad have any sensing of what is going on in the feeder?" Not with the feeders we use. Same deal as the Topaz, i.e., the machine knows if the nozzle has a part on it, but doesn't know what is happening in the feeder. There are "smar

Maybe a silly question, but........... Sometimes we get PCB's in with defective(distorted) fiducials that the production equipment(printer, PnP, etc) does not recognize. It would be great if there was a product out there to replace the defective f

I don't know how accurately you're going to be able to put a replacement down. You could use BGA replacement pads, but that is a lot of time and the results will be shakey. On the DEK, make a copy of your program and teach some pads or through hole

Paul, My sincere apologies for striking a nerve - that was not my intent. I do not work for a board house, nor am I pushing anything on you. My comments only come from my history of having to use parts that made manufacturing a nightmare. I do unders

I have read all the replies here and have yet to see this one which I know works when our fids are HASL and distorted, thus unable to seem uniform enough for the vision systems on our MPM's or MyDatas to see them clearly. Using a stainless steel nee

All posters here are right. My point was you have to design your board to the process. You cannot simply take any connector and change it to Pin and Paste. So much depends on your aperture openings, hole size to pin size, board thickness, number o

I am looking for people that are having problems primarily with test of their product after reflow/production. Has anyone experienced a great solder joint but the component still fails test? Has anyone had dewetting of atmel components, pull back of

Since no one has responded I'll give you what little I know. My last place of employment used MSH-IIs and an MPAV-2B. As far as I know there is no optimisation capability at the machine like there is with your Topaz. The programmer used Panasonic
