Even though you may find a pad-pad thru-hole spacing, part body size, orientation, and insertion head tooling clearences may be the deciding factor in spacing. 1. Part body diameter will dictate component centroid spacing. ---[][][][

| Is anyone aware of a web page for military spec's? I am looking for Mil-P-28809. | | Thanks, | Mike Demos | MIL-P-28809 is definitely obsolete. Not only obsolete, it was possibly the most scientifically flawed standard ever to to be printed. I

Mike -- Thanks for the information. It is very helpful. Is there any information available that shows what flux most companies are using? What fluxes are most companies that are producing Space, MIL-Spec, or other high-reliability assemblies usin

It's difficult to diagnose without the LED specs. Is the spacing between the pads the same? Your pads seem too large for the Nichia part. Try reducing the stencil apertures to deposit less paste and closer to the inside edge. Depending on your oven,

Hi, Kris You mean you have checked the tape&component demension,all in spec, But could you tell me the spec of the tape cave size,I mean how about the gap between the cave and component? Do you have such spec.for 0402 Component? Please inform us

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.

I wouldn't touch one of these Chinese machines if a reliable "no headaches" experience is what you are after. I'm sure they do OK for whatever it is they are designed for, but actual volume production not so much. As others have said, proper machines

You mentioned that you changed the layout some, and this can be essential in this type of process. If the SMT parts and TH leads have inadequate spacing on the bottom side, shorts may be inevitable (someone else will have to advise what the recommen
