Hi, Does anyone have guidelines on minimum SMT component spacing for bottom sided wave soldering? I am looking for general rule of thumb in wave soldering bottom side SOTs, 0805 & 0603s. How about minimum through-hole lead to pad distance? Peter

PTH to SMT spacing should be 80-100 thous. any closer will result in bridging. Scott

Ooops, sorry Peter. [Those pesky decimal points.] I meant to say �150-200 thou�. There is a fair amount of 'Kentucky Windage' in this due to: * Height of the component and the down-stream spacing. * Chip wave capabilities.

A gap of 150-200� between potential shadow components is enough to eliminate those problems. Dave, Can you clarify? Do you mean 0.015 to 0.02?? Peter

Many people use the same spacing [and pad designs] as they use for primary side SMT. We don�t. DOWN STREAM SMT-TO-SMT SPACING: In addition to proper orientation, components cannot be immediately upstream of terminations that are to be soldered or b

Hello All, Are there any documents that list component spacing requirements in terms of DFM/ DFA. I was going through IPC website but wasn't able to find any. Thanks!

This will usually be driven by the accuracy of your pick and place and common sense.

We'll guarantee the two pads are too close together. The proper spacing depends on the orientation of the parts to the wave. * Do the pads hit the wave at the same time? * Does one pad hit the wave before the other? If so, which? * How does the 06
