First, I don't have a clear fix on the problem. Please drill-down to more detail. We appreciate that you probably don't know the parlance. Just describe what you have and then what you'd like to have. Second, most 0402 LED are fabricated just lik

This does not look difficult. It appears the rectangle of proper size and spacing would work for both, or even a square pad. Don't make it more difficult than it should be. But then I could be missing something?

To prevent BGA (Ball Grid Array) issues related to SMT (Surface Mount Technology) solder resist when fabricating a PCBA (Printed Circuit Board Assembly), you can follow these guidelines: Design considerations: Ensure proper spacing between BGA pads

Desire to push the spacing limit as usual. If I place two 0402 components spaced 7mils between the edge of the two components adjacent pads, which allows for 4mils solder mask webbing between component pads, what would the risk be? Potential for sold

What is the industry standard pad geometry (dimensions and spacings) for 0402 components?

sometime hand solder can cause also. no necessary have to be paste n reflow.:) now i'm facing bridging on 0402 components pads. any suggestions on spacing distance as we're going to re-design the pcb.

| Hello | Is there anyone who can give me some information regarding yield from gluing 0603 | Is there any other problems that you might have had. | | We glue bottom side 0603's but have changed our pad spacing to accomodate tolerance requirements

Check your land patterns. I believe someone once made a typo on specs for land pattern spacing and the specs are still being used by some people. I worked for a CM that had a customer that spaced the pads for 0402's too far apart. It was the only

I need advice on a pad design which several other engineers whom I work with would like to try. I think it is an utterly crazy but I can't seem to convince them differently. My current 0402 chip pad sizes on alumina and FR4 substrates are .022"X.
