| After reflow proces in convection-IR oven we find broken body of SOT23 elements. There is no problems on other elements (SOIC, chip R,chip C, etc) | Where is the problem? | | Thanks in advance! | Check your profile at the site of cracked component

| Hi Folks, | This is my first surface mount board, so I asked our assembly house for some tips. They said only passives on the bottom side-preferably no smaller than 0805, 0603 only if I have to. I would think that an SOT-23 would be OK on the botto

Robert 1st Short term, let us know what type of machine you are running. Maybe somebody out here has a trick to get you buy. 2nd Long term, check the pocket dimensions against VS what the manufacturer of the part says it should be. Drive correctiv

Dave Thanks - have changed to a slightly larger one and it has helped quite a bit, but I feel it is still not perfect. I think I am going to write this one off to a pachaging problem on this one particular device. It is a new machine (2 weeks old) w

Weare using a Home plate design on 1210 or larger, 20% reduction on pkgs from 1206 to 1210, 10% reduction on 1206 or smaller, 0 reduction on all leaded components(sot-23, IC's) with a 6 mil stencil. For fine pitch we are using 4mil stencils. We h

I am evaluating a bottom side glueing process. I was wondering if anyone could share their shear force specifications, or how they were developed. I would be most interested in the 0805 and Sot23 package types. Also, does anyone know if heating th
