Am I doing my maths right? 0.005 inches is 0.127mm which is crap for a stencil. Our supplier (laser cut)has an aperture tolerance of 0.005mm (approx. 0.000197 inches).

Can anyone advise a good starting point for a temp profile for on 0.05" and 1206 component boards? These boards are simple by todays standards and do not contain any fine pitch or other special components. Thanks in advance... MM

how to solder manganin 0.05mm manganin wire to a copper plate

Go with no greater than 0.005". Pleanty of paste and minimal shorting issues. 0.004" will even work

If you failed math like I did. A 0.005 inch stencil would work fine for those parts. Most stencils are 0.004in for fine pitch 1005s 201s. 0.005in is probably the most common generic stencil. 0.006in generally is if you need extra solder for big parts

Does anyone have any experience in printing solder paste on a 0.0065" pad? I have a requirement to attach single chips with 600 to 2400 connections. The chip has a 0.005" solder ball, 0.010 pitch. Attaching to a substrate with a 0.0065" pad. An

Does class 2 vs class 3 PCBs effect variance/tolerance in terms of actual positioning of pads/traces? For example, if fiducial is to be at 10mm. What's the tolerance for class 2 vs class 3? [variance allowed] Does panelization have any effect on t

Where blank are the balls on a BGA supposed be? UNDERNEITH, dammit!!! Fire that inspector. It's good that you have your balls imbedded in something, so that they are not rolling around. Beyond that, consider the five ball system! - No more than

Sorry, scale division on that would be 0.05mm not 0.02mm. Magnification x24 or thereabouts. Also great for measuring all sort of things on pcbs, stencils etc to see if they come within spec.
