I have seen 0402 inductors that look identical to 0402 caps, come in embossed reels, but the pitch on the tape was 4mm. Im not saying they dont exist, but i have never seen an 0402 component come in an embossed tape with a pitch of 2mm. everything i

Hi, I am trying to reduce some 0402 cap tombstones. The main cause is the pad spacing is a little too far apart and the parts are as tall as they are wide .5mm I am stuck with the pad spacing for a while. All other parts are soldering well, even 0

Hi, follow up, Thanks to everyone that responded. We finished the build, the sun burst thru the clouds and the birds sang. Well that was a slight exageration. Sorry for lack of detail on the original post, I was frazzled. Since the 0201's were p

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

Les, Some of the answers to design or stencil aperture/placement machine depend upon what is the current spacing between your components which you didn't specify. Chip components such as 0402's and 0201's typically have very small reductions in pas

We're having some problems with 0402's tombstoning. On a board with about 300 parts we're getting about 12 to 20 tombstones per board. The caps seem to do it more often than the res. The pads appear to be in accordance with IPC SM 782 amendment 1, S

run the board thru both backward and sideways and see what happens

Also check for any Vian-in-pad designs that could cause the problem.
