First, let us pause for a moment, bow our heads, and say a small prayer for Ill. Second, the only thing that is absolutely necessary is to do some things that make your customer feel that you're smart and did a comprehensive job of assessing your ne

We just got a contract to build a board with 1400+ SMT placements. This thing is 16" x 12" and the PCB thickness is 0.142". Dead center is a 580+ pin BGA that costs about $600. I'm a bit intimidated... I've done lots of mole profiling on BGA's bu

Thanks for the posts everybody. I thinks this is all or nothing, I mean set up my own business doing this stuff or forget it. I've been involved in SMT for about 5 years now and feel pretty confident with the process stuff. Just curious to know how

Fowler: Thank you for your documentation. Your finding roughly coincide with our own. We also found that 70 degree baking removes 50%/60% of the ingested moisture from moisture conditioned MSD packages We ran an additional experiment that compared

Good to know there are a few smart people left in this industry like Darby. I love how everyone assumes the original poster was only talking solder paste. We use screen printers for five different materials. Some of which we triple print by design

Not you Steven. Blanket comments like "Double pass printing for solder paste is not needed and will cause defects. Redesign your stencil thickness or aperture sizes, change your paste mesh size or type, go to 45 degree blades." are so way off base.

although the cp643 is much upgraded and a little bit more complicated to those person whos luck of technical skills, i would still prefer to use this machines because it would give you more productivity than cp6400. on the mechanical aspec of these t

Hi JD, We use the OM-310 NC for most of our lead free work and see some wetting issues. We also have a lead free produst that requires cleaning so we use the WS-819. It does seem to wet better although I have never tried the WS-819 on the same b

We all know that Engineers are human and consequently may make errors when creating pick and place programs. (e.g. program a wrong part number for a given reference designator) Usually that is easy to detect since the wrong component is a differnt p

Hi, That's great, and I did not know this was possible, as I did not see that thread when I searched the archives. Do you know of any companies that take your board outline and will design a palette to hold it through the printing, smt loading and
