| We are a medium sized PCB assy. house manufacturing about 2000 motherboards a day. There is a major problem we are facing at the wave soldering stage, i.e. warpage of the PCB. As soon as the PCB touches the wave it warps severely from the centre

We are using so called no-clean fluxws for our small batch production, however the results are not always very visualy pleasing with white powdery deposits being the norm. I would like advise on the best avenue to explore for a small batch cleaning s

fiducials

In past PCB designs I have cleared all traces from all layers (except pwr/gnd) from fiducial area. It has come to my attention that this is only necessary on the side where fud is placed. Which is the correct method of design using a fidicial?

Hello Dan, I have recently started using polyimide, but not for the standard uses. I designed a pallet for holding small, thin (about .0018" thick) RF boards that were being reflowed inside their aluminum housings. They were screwed down to prevent w

1 mil or 25 um trace width

Can anyone in this world produce such small PCB/PWB trace widths? Lots of theory so far, but have not found anyone yet who can do it in practice.

What is the current spec for sizing PCB pads for a land grid array? How about for a ball grid array? Are there industry spec's I can reference? Thanks, Frank
