Luckily for me, if the part were soldered and on the board prior to any processing, I will still be able to build it. I am currently experimenting with screen printing a high temp paste, hand inserting the part (even Chad hasn't come up with an econ

Back in October a post went up re: the fact that a solder manufacturer quit recycling paste, and the responses then weren't encouraging, so I'm gonna stir it up again. I haven't figured out what we're going to do with ours yet and it's piling up. N

I think you could look at the phenomena in two dimensions. Many of the sub-contractors in Asia are focus on low price-less demanding products. They hire operators to visually inspect the boards and sometime there is no inspection at all. On one ha

Hi Wayne, Why do you feel that your solder pot needs a fountain for this application? It is always nice to have a mini fountain wave but it is not always a must. Good flux and a steady hand go along way. Iether way you will need a steady hand! Th

Sean, Have you contacted Speedline Technologies applications enegineers? They have a lot of knowledge about SPOTT working with customers over the years to develop the process. I myself have experience doing SPOTT. I used Fuji GSP2 printers with overs

Are the tin/lead ratios compatible betweem HASL and wave solder? Probably are, just a remote possibility. Flux application is? bubbler, sprayer? Either way, are you getting good misting, coverage on those teeny 0.5mm test points? If not, then no

The basic rule of thumb (info current as of 9/2000, from Ceeris and others) is the 10X multiplier for each major process step. Catching a defect and correcting in SMT will cost $0.10 each. (think about $.04 placement cost, stop line time, operator h

Hello We introduced OSP finish on some of our products but now need to add some discretes at the end of the process. From my little knowledge of OSP, this is difficult. We'll SMT the boards and transfer them to another site for further processing.

Jay In reference to your original question ( not including my previous off-hand remark ) I have not heard that multitronics will be the only machine from the new tyco company, but if it is true i think that would be the single most foolish thing they

Hi Steve, 20 mil pitch shouldn�t be that problem nowadays. In your case bridging and poor wetting seem to go hand in hand. For the poor wetting try to eliminate it by using different paste (higher activated) and work on your profile. Coplanarity also
