You are going to struggle with that sort of connector - the only pin headers that seem to have widespread sucess are the dual inline ones with bent over j leads that sit on the board. They come with a plastic hat that allows vacuum pick up. However

We are using Alpha UP78, which has generally good SIR values. We are seeing current jump from around 6 micro amps to 60 micro amps in a very small percentage. This does not seem to be likely with just ions immediately after reflow. The current would

Hi all, I need to find a solution for a problem I have. I need to replace BGAs which have been glued to a laptop board with superglue (Loctite). How can it be done without removing the pads when trying to remove the foreign glue? thanks in advance

I would measure the voltage on the yellow wire going to the air pressure sensor. Are you getting 24VDC? If so, maybe replace the input DC module on IO card #2. I think it is IDC module 8 on that board. Try not to have too many violent thoughts.

I don't know anything about your machine, except that Nicolet was purchased by VJ Electronix. I contacted VJ about another model of Nicolet X-ray machine, and Rick (978-425-9446 ext. 1251) gave me some good information. He's a former employee of

We sold ours a few years back - it was adequate, but nothing great. It was only top down, not one of these wonderful tilt & view at any angle machines, but it did a job for us. We never had any BGA related problems as we had very good engineers, so

We use a single large pad on board and reduce stencil aperture 50%. If you mask/reduce the thermal pad the solder will not wet out to edges and you will still see the part standoff with the open joints. the purpose of reduction is to wet the paste

Just to comment on the quad equipment side......The QSA-30 is also obsolete but you can use the same feeders on it as the 4c. The setup time would be the same but the speed is quicker (i think around 10k cph). If I were in your shoes....i think i wou

I just installed a new CCD in a 4.0 mil upward looking camera - GSM. It's working well but is slightly out of focus. Do I adjust focus by moving the lense in and out of the camera mount or do I use the ring that is actually part of the camera that

Once a rock star, always a rock star, eh bubba? Ozz don't forget stuff like that. After a half liter of golden merriment, I don't care about how odd the food tastes, I just want to remain agile enough to dodge the sinkholes on the way home.
