Tom,

Laser cutting openings with these spaces between is not an issue.

Subject: [TN] Solder paste slump patterns


Got a question, I was looking at the IPC-A-21 solder paste slump pattern
and noticed that some of the spacings between pads were 0.05mm, .1 mm-
this is .002" and 0.004"-  and I can't imagine being able to etch a
stencil with these spacings. Am I reading something wrong here?

Any other newer solder paste slump patterns out there?

Thanks
Tom
