Russ is correct. We have been using SAC 305 for SMT and SN100C for wave and selective and repair for about a year. May switch to SN100C in SMT at some point if we can get some paste that wets better.

Please give us more information about the source of the solder that you mention. Is it: * HASL applied by your supplier * Solder on pads after wave soldering * Solder paste after printing * Solder on pads after reflow soldering ... or what?

A water soluble solder paste (AIM WS483), reflow and wash. We are considering using AIM NC254 No-clean solder paste to eliminate the wash step.

Have you looked into Sipad? They will pre-paste your BGA and other component areas with solderpaste that has an adhesive on it. You can then hand place your components and run through a reflow. Here's their site: http://www.sipad.com/

Let me see if I've got this straight...rather than hook up a MOLE or a KIC profiler to each and every board (600 P/N's in my case), most people are making judgement calls based solely on how similar a board looks to another board, for which they have

Don't let quoted speeds affect your decision too much. Send copies of pick and place files for actual products you intend to build and ask for simulated placement rates that would be achieved. Our machine has a rated max placement rate of 15,000cph a

It will be tough to get a good line for that cost. You might want to start by looking at Mydata and Juki for the machines. Ekra for the screen printer and Heller for the oven is where you might want to start. If you have not already you might want

We went through this with one PBGA supplier recently and they were able to get the problem under control by fixing some of their molding processes that were inducing residual stresses. You can really see it in a thermal moire where you measure warpa

Paul, I work for a supplier of 2D and 3D x-ray inspection systems. If you are interested in discussing alternatives to AOI for post reflow SMT process monitoring and inspection I would be happy to discuss several strategy considerrations with you. W
