Hello guys, I'm a new learner in PCB field. And recently, I have summarized some basic information I learnt on how to arrange the line on crystal oscillator, but I'm not sure if it is right. So I'll write it down below, hope anyone who may read my po

We are installing via reflow soldering a crystal that has 2 pads, 1 each end. They are flat pads on the bottom of the part with a small area of the pad looping around and up the side of the crystal on the end. Inspection of the cyrstal under a 40X

the only components I have had trouble with so far are PLCC68 and larger, Large Coils (2b and 3b size) Heavy crystals. Some BGAs if they are not PBGAs. There was a discussion on this and a formula was given to determine if a part will hang under th

Hi Evtimov, For BGA's you place 4 on each side right outside the edge balls and it pulls the case down and a bit is pulled between the balls on reflow. Not tried gluing a crystal (they only gave me a strip to play with)

We are a small company, reletivly new to doing our own SMT (1 year) and we are having an issue, I think. We manufacture many board with no problems, but we have one that constently defeats us. This particular PCB has ENIG finish, and we have had th
