I guess I've been somewhat ignorant when it comes to the finer details of pcb layout. Lately I've read a couple of books that try their best to lead me on the straight and narrow. Here is a couple of examples of a recent board of mine, and I have hig

For those of you who use via holes as test points, and the via holes must be filled at the wave, is it necessary to have a "dome" on every single test point, or is it sufficient to have the via "filled" with solder? The ICT preson here insists that

We have some circuit boards where the solder mask seems clear instead of green on top of some of the tented via pads. No gold deposited during the ENiG process and no solder sticks to it but why is it clear and does it have any correlation to the thi

Dreamsniper What is the rationale for the double plugging? And why from both sides?

It makes sense if you think about it. Siemens was a dead company ready to fold up their tents back in the 80's and early 90's. To their credit they stuck to their platform...got somewhat lucky and the market sort of came to them as the wave of users

Pete, is there a probe-style that will accomodate a via that's filled, but a little concave (inward) fillet? The ICT personnel complains about this scenario too. I'm not an ICT person, but I do know that there are pogo pins that have a crown (for t

No dome needed. You should check what type probe you have. You can look here and consult with them: http://www.qualmaxamerica.com/qualmax/leeno/semi.asp?string=ICT

For most applications, a nice square [or rectangle] pad works just fine. Assemblers ship boat loads of boards with these every day. It's reasonable for tight decoupling capacitor requirement applications to use round or radiused pads for components
