Hi All, Just wondering if anyone is placing 0201 components in volume. If so What pad layout are you using, i.e. pad size, shape and spacing. Also are you pads and fiducials solder mask defined or copper defined. Can you also let me know the rough q

WE have a problem with a DPAK component floating during reflow, causing it to move to the point where it affects the toe fillet. We have been using a dot of SMT epoxy to hold it secure for the moment. I have looked on many sites, but no whrere can

Would anyone have experience or information on where I could find pad geometry for tantalum capacitors that can be surface or plated thru hole mounted.

Help I have just received some PCBs with external tracks entering SMD pads at all angles, tangents + 45 degs etc. Where can I obtain information as to how tracks should enter SMD pads.? I have looked at several IPC books and got some minor info but

I am using the old Tango for DOS to create an board with a 1mm BGA chip. How to define clearance around the surface pads?

We don't know anything about using "old Tango for DOS". First, consider the fabricator of your part as the THE most appropriate place to look for layout recommendations. We've discussed the heirarchy of sources for layout information previously he
