We use the same oven for both Pb and Pb-free assemblies. We have been for about two years. We have not seen any issues with contamination. I can't imagine how any Pb would end up in a Pb-free joint in the reflow oven. The Pb doesn't vaporize, the

In the design stages, we have been asked about the difficulty in soldering a 4AWG (stranded) wire to a PCB for a high current application. Questions - can this be hand soldered normally? What about wave? Process will probably be Pb-Free. All opinions

Mr. Long, me lad, I don't follow. You say stuff about RoHS and all the banned materials covered by RoHS, but what is your theory on how banned substances can get on a RoHS board if you are running both Pb and Pb-free on the same oven?

We have recently acquired a Pillarhouse Jade machine which has changeover pots from Pb Free to Pb and the bath it small so changeover heatup is fast . Although it's runtime is slow it seems to run the product well.We are also running an Ebso 400 but

1. If I go to the Pb-free solder paste, is it necessary that I have to change my reflow oven OR just by changing with respect to solder paste specification, I can reach my goal? 2. What is the �Low- Temperature Phase� in any solder paste alloy? 3.W

In general two step temperature reflow process requires minimum 40 deg C delta to be sucessful. We are not using vapor phase soldering but we have similar situation when we change to SAC lead free solder for PCB component population and secondary swe

The clear plastic packaging for LEDs is a LOT softer thermoplastic than the thermoset epoxies used on ordinary chips. I think people have had high failure rates when reflowing LEDs in all-plastic packages even at SnPb temperatures, and much worse at

I think machine selection depends upon your application (pitch, volume, changeover from pb to pb free etc...) I have experience with ERSA and Pillarhouse Jades. Both very good in their own right. Pillarhouse are relatively cheap, and quick to chan

Currently we are using a 2 step vapor soldering process to manufacture our std. lead soldered parts. The first step was done with a ls240 vapor fluid and the second was done with a ls200 fluid. Using a 221 deg C sn95/Ag5 solder for the first step a

Hi, What would be the standard band width for Pb-free soldering? As per my knowledge this should be 3cm to 6cm. What is best?
