Standard pad sizes for reflow and wave

Electronics Forum | Thu Sep 02 21:02:55 EDT 1999 | Paul Wareham

We've noticed that there are many different recommendations for pad sizes for various SMT parts. This seems to vary wildly from manufacturer to manufacturer for the same case sizes. Is there any standards that can used used to specify these sizes?

If that's what you mean, here's what we call them: ROBBER PADS... Pretty close to the "thief" I guess. Those come with the design and if the wave soldering direction is not known at the time of design and/or there's no real estate limitation, the rob

Blow hole on pad after reflow oven

We've never seen the defect that you describe, but in wave soldering-land blowholes usually are caused by moisture in the board that out-gasses through the too thin plating of through holes. * Bandaid fix: bake the boards * Long-term fix: Obtain boar

i've rotated the board with the same result. What are soldertheif pads. I'm new to wave soldering and this is another new one on me. What did you use? where do you put the pads? please explain as much as you care to...also my leads are 1mm and th
