Can anyone help me on where to find reference for the above info other than IPC2221 as it is not covered by the said standard. I am looking for a proper trace spacing for my lightning protection circuit on my PCB for the following requirements: 750

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

Could someone tell me the recommended board spacing when going through reflow? I've heard a couple different things so I was wanting to get other opinions. Thanks Bob

No max spacing spec. except that it should not be so far away from the other one that it is no longer on the board! IPC 782 shows .5mm spacing for the min.

So I set up a board yesterday and did a test run. It appears that the spacing does matter on my machine. It placed the part off-center the same amount as one of the fiducials. Im going to look more into fixturing and placement pressure adjustments I

I agree - beware of the cheap imitations. To date, I have had very good experience with the VectorGuard technology. A bit more pricey - but usually worth it.

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.

Yes, courtyard gives you the space requirement of a component. Sometimes, the working space of a rework tool takes precidence, though.

Chris, If the short in the picture is parallel to the wave turning the board 90Deg will solve the issue. Because then the lagest spacing will face the wave parallel and the smallest space perpendicular.

I'm thinkin you can buy a lot of stencils for 200K. If you are worried about floor space, buy frameless, or space saver stencils. Will not jet WS paste.
