First, I agree with Wolfgang, in response to Wister. Second, Wolfgang: Sometimes, our blanket purchase order for paste schedules delivery of the paste in advance of production requirements. (What!!!???? In-bound material schedules don't match out-

JEDEC and IPC for instance do have conventions. But they are only typically for existing part types and do not coincide with one another. I think the bigger problem is the new components and the unusual components that don't seem to fall into any p

Of course when it gets too thin it becomes difficult to remove! D^%#$'d if you do, D!@#'d if you don't. I agree with Jerry we also run the stuff semi wet when we have to. Do you have the possibility of getting these masked prior to assembly like t

Hi Lawrence, I would agree with that in the main, however in some cases some machines can be almost "timeless". We don't go below 0402 (1005), missplacements are negligable, and a actual placement rate typically hitting 28-30K an hour makes "upgrad

Yup, I agree with you. Don't let the 90%er win, rise above it. Keep a sense of humor, cause you'll need it. Ya gotta admit, when the Gruesom 4-sum post here, it is kinda funny. But then again, I've been at this for over 20 years, so maybe I can s

I agree with Rob that voids are often times paste-dependent, and it's all about the type of flux that's used. The cause of the voids, as you all know, is outgassing of flux which has nowhere to go with BGA's. Some paste mfgrs. will recommend going

0.031" radius is a diameter of 0.062" which is very tight (small) for a rounded corner. I would tend to agree with the board house that is can not be done. 0.031" is a standard thickness of PCB. I think it is very possible that your customer swapp

We agree with Se�or Tech. We feel that it's more important to monitor the contact area of the squeege for bending, dings, and whatnot that could damage the stencil than counting print stokes. Just the same, ya just have to love those clueless qualit
