Dear Technetters,
For our stencils I have recently introduced the homeplate design for the apertures of chipcomponents larger than 1206.
But now a problem occurs with the guys who have to order the stencils: it takes a lot of time, by using Gerber data, partslist and assembly drawing to figure out which components are 1206, 1210, 1812. For a coil or tantalumcaps with such a footprint I don't want a homeplate aperture because these parts need a little more solder.
So we end up with a nice specification, but very unpractical for the production engineers.
How do others deal with this ? Mabe you have suggestions on how to make an easier-to-use specification ? Or ideas about easier ways to order a stencil according to my spec ?
Should I keep it simple and say "use homeplate-apertures for all footprints larger than 1.5 * 1.5 mm ?"
