Q1. What is the recommended stencil thickness to apply the proper amount of solder for 0603 components? A1. The proper amount of solder is determined by: * Metal content of the solder paste. * Stencil thickness. * Aperture opening. * Other factors,

A little adition to Norm's statement: Sn-Pb intermettalic compounds do not accept solder as they are (even without being oxidized).

Below 40 microinches = Bad Solderability With pitches getting smaller and smaller flatness becomes more of an issue, but it's not to be achieved by blowing ALL solder off the pads.

Maybe trying to get a flatter HASL PCB. But i am unaware of the "entire industry" trying to go thinner. Russ

Fire them now! I don't know if your a CM or not but in that world if we do not follow our customers instruction and specs exactly not only would we be fired we could get sued!

Aperture size should vary with the component [pitch]. That size should be the same a the pad size. So, generally pinching is not required. Indium discusses BGA apertures on their site [ http://www.indium.com ]

1 um". Some PCB manufacturer is telling me that this specification is not feasible in production. I would know if this position is due to the equipment (or process control) they have, or if in effect is not possible to satisfy my requests.
