We work with a lot of larger boards over 24", haven't run into this issue yet. I agree with scott could be your board supplier if they are lower quality, from something as simple as unit conversions in CAD to dealing with different temperatures. A

There may also be a problem with the a thermoprofile. Measure the temperature of both contacts of the component, if they heat up not evenly and the soldered lead heats up faster, then the problem is in the profile. To solve the problem of misalignmen

Hello I have a new 0402 pad design on a recent board were building in future. On closer look i thought the pad was a thru hole mount , but upon closer inspection the round pads are for 0402 comps. I had a discussion with the engineer and he said

Hi, Sounds like your engineer does not know what he's doing. We have developed and built hundreds of thousands of boards with normal square pads for 0402, and we just use a 5 thou stencil with 5% reduction and it works well. Decoupling? What is tha

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

Indium recommendations: 0201's: * Stencil Opening = 11mil x 16mil rectangle * Foot Print = 12mil x 15mil rectangle * Stencil Thickness = 5mils * Spacing = 9mils Note: The most common stencil being utilized, is the laser cut electropolished, and in so
