Wave soldering : pin to SMD distance

Wave soldering : pin to SMD distance | 7 June, 2007

We noticed unsufficient soldering on some 0805 chips located between pins from a plastic bloc connector . All chips are soldered with 45� angle. Flux quantity , preheating , contact time and PCB quality was checked. Do you know any international standard for a safe pin to SMD pad distance ? I would appreciate any of your comments !

There is no standard for the spacing of components, nor should there be.

We have a difficult time picturing your 0805 at a 45* to the wave and the safe pin, but we'd guess this spacing needs to be 10 thou.
