Grant, I dont quite understand the implications my self yet on gold deposit using FLASH or ENIG. However the important part of the gold finish is that it is kept under 3% of the total solder joint, so normally its safe. With the FLASH process it is m

we shouldnt be talking about lead free we should be talking in terms of RoHS compliant. HMP solder is exempt in the directive even though it has a hig lead content (93.5%) as no other alloy will melt at the same temperatures 298. as HMP is exempt wi

Hello Greg, I agree with you that the article in SMT Magazine should be studied very carefully as it contains many errors in respect to SN100C. The testing performed was a DOE and was not an optimized run. There is also a statement on dross generatio

I take it you are talking about the older style IP feeders. If so, here is what you need to do..... Get yourself some mineral spirits,a tub you can submerse the parts in, and a couple nice paint brushes. 1.Dismantle the feeder and wash all of the

If your component meets ANSI/J-STD-002 - Solderability Tests for Component Leads, Terminations, Lugs, Terminals, and Wires, then the problem is at your customer's operation. If the problem is at your customer's operation, it's very difficult to anal

I just went through the same problem. We have an inductor that is made with a bundle of 30-strands of Litz wire that is vaccuum coated with varnish, and have the ends of the wire bundles tinned that we have to solder to SMT pads on the board. The ind

Why don't you guys look at the "WORLD LEADERS IN SOLDER RECOVERY". EVS International make the EVS 3000 and EVS 6000 Solder Recovery Systems. Many other companies have tried to come up with different ways of recovering solder but the EVS is the best

Hi I use a lot of preforms for other specific applications. Personally I like indiums product but the lead time is awful and dont often deliver them on schedule. (im in the uk). Some manufactures make preforms out of solder wire that is pressed flat

I assume you talk about wave soldering. No-clean fluxes are widely used since 1987 or earlier and after all these years they have proven to be reliable. If you clean the board or not the dust bunnies etc. will still reach the board surface. If you us

Howdy aj, wow! Be prepared for serious problems with corrosion of your stainless steel workings of your pump. Last I looked changing a wave solder pot over to nitrated coating for electrovert was in the neighborhood of 18-20K. I'm not a betting man
