Not now, Valor may under develop the module for its Trilogy 5000 with the stencil aperture based on the rules which you set. Also, check with IRI stencil (Alpha), they have a s/w and based on using ODB++ file and not Gerber. Rgds.

which stencil vendor can deliver aspect ratio and area ratio and the statistical information to the user?It's difficult if the pad is modified.

and the two ratio is changed if you use different thickness sheet or step-down or step-up.I think real time calculator of the two ratio is very important for tranfer efficience.

Go one to one at 7mils for these connectors. Generally your stencil shop will do this for you. Somebody has the artwork since a stencil was made for it at sometime? Russ

I was wondering if anyone could direct me towards documentation on shear test methods/apparatus to test the bond integrity of a solder ball to its substrate. Thanks.

I recall a couple of papers in the SMTA 'Knowledgebase' that used ball shearing and an element in a study that compared BGA [maybe uBGA] component fabrication methods, er sumpin.

What is the recommended prep for a through-hole glass pack diode? Should a stand-off be used or can it lay flat on surface of the pcb?

Hi guys, What are the major inefficiencies that most EMS companies faced in a high-mix/low-volume manufacturing? And, what in general an equipment manufacturer (especially surface-mounting equipment manufacturer) can help them to improve the product

Change over and flexibility are two critical areas you need to have controlled in order to be successful in the high mix, low volume market. Machines to consider: SAMSUNG CP series, MyData My series, and Europlacers.
