Hello, I know nobody asked, but here are my 2cents on the newer, more comercialized layout of the forum. I frequent many of the SMT/Assembly forums and the ones I prefer to stay with are the ones that are NOT comercially oriented. Not having comercia

James Take a board with double sided tape and run it with all the other parts "shorted". Make sure that the part is being placed by the head/spindle that will be used during a full run. Inspect the part after it is placed and carefully remove it a

I recently started at a new company. They have a variety of bare PCB's and most have aprox. 20 variations. Maybe about 1/3 of each board on average are non-populated locations. They buy one stencil for each PCB but then use scotch tape to block of

No, not as such. Nor should there be. This is not to say that the issue of making good prints is anything but absolutely vital to cost effective operations. Experts attribute 60+% of SMT soldering defects to the printing process. Properly, both J

Steve, I have done BGA work with and with-out Xray. If you are going to install them in high volume it makes sence to have every thing including rework on site. If you are just going to put down several a week you can probably get away without th

Where I worked previously we had some boards with a couple 15 mil pitch parts. The first batch we got all had undersized pads. We had lots of bridging. We had less bridging with bigger pads. The ball size in the paste makes a bigger diffence regar
