really need help!! Our company is experiencing a change on the Quality system. one of the things that we are discovering is the amazing variation during the reflow oven and wave solder processes. this week we found that the team had not been performi

Sure, to be a true lead free enviroment all components need to be lead free or fall within the specifications of lead free as defined by the RoHS Directive. What I am doing is starting stage 1 of our journey. Layed out it looks some thing like this.

Indy, I found the same findings as you. The claim is that the solder joint may actually look closer to a SnPb solder joint then the SAC alloys. I had commited to the SAC alloys at SMT before finding out about the SN100C alloy. I'm interested in what

Hi Frank, we're still going to go with FR4 as our prefered material. Our board thickness is .062. We use an on shore and off shore vendor. Prototron I believe offers an immersion tin and excellence in china? offers an immersion tin finish. We fou

Hi Tom, Thanks for the compliment. I've been researching and planning for the time that my company would go lead free since late in 1999. I hear you there, how do we know that the component is lead free. Baring a leap of faith with your vendors, I

Ther is a solder alloy out there that is supposed to allow lead free wave processing without having to upgrade pumps and such or increasing the pot temp (direct drop in). I have not used it nor do I plan on doing leadfree wave soldering but you may

Not as such. Generally, people tailor their profiles to produce glam solder connections on their boards. Search the fine SMTnet Archives for discussion on the factors affecting solder reflow recipes. What is the best way to get these PCB made to s

This looks like it may be a good application for an Air-Vac or Wenesco type solder station. It is a solder pot that has a small motor to pump solder up through a chimney. You can put different nozzles on the top of the chimney, so you only apply sold

Try lifting the part with a small piece of paper. I've seen caps that did this and giving the flux a way to vent out the top side of the board got rid of the blow holes. It'll take ya 2 seconds to to try - that plus the 3 minutes to wave solder.

Hi May you let me know where I can find information to generate wave solder profiles
