We have both DRS24 and DRS25 Lead Free rework is done for the most part on the DRS25, although the DRS24 can handle some of our smaller pbFree assemblies. We bought the DRS25 machine new, it was not an upgrade. The machine is very successful at pb

Steve, your best solderer in your shop will know that this ain't standard wire solder. I always put the best solderer on T/C attachment duty when I have a scrap PCB to play with. They even have difficulty getting the stuff to wet to pads and leads.

I can't answer for wave, but we tried some Sn100 paste for reflow, and couldn't get it to work worth a darn. I then got some SAC305, and was relieved to see it work almost as well as SnPb at its best! Much better wetting and flowing to the various

I have been using sn100c for over a year now on our wave solder process and I am plenty satisfied so far. The secret for success with this alloy is to have your solder pot near 270 celsius and your dwell time has to be near 4 sec and your temperature

Josh: Your 0.009" [0.228 mm] clearance should be fine. The minimum clearance should be ~0.008" [0.20 mm]. Is the 0.039" [0.99 mm] the measured or the expected hole diameter? While we wouldn't like it, we wouldn't be surprised to see 0.008" [0.20 mm

Could be any one of the 3 you mentioned, need some details here, do you really think we can answer this question as it is? Now for your issue, what is the make up of the lead itself on the part? what is the reflow profile at this part? what is

If you only manufacture PC Boards with valid RoHS compliant componenets, then yes, your Pb is your only concern. If you add any type of other fastener, housing, wire, etc... it also must be RoHS compliant to be certified. Too many people focus on "

We've just completed an experiment for one of our customers using lead-free HASL. From a manufacturing standpoint, everything seemed to have run fine. Solder profiling seemed to be unaffected, pick and place was unaffected, and the end result looke

Hi, I am using a 7 zone Conceptronics oven and Indium 3.1 lead free clean paste. Our profile is as follows, 130 140 150 180 200 240 260 with a belt speed of 36 inches per minute. I dont know if that will help you out though...

Over here in Eurolandia the following Allois are running like a piece of cake. http://www.krepro.no/tinn_pasta_fluss/NiGe-Stangtinn.pdf It is FUJI patent Formula, sold in Eurolandia by FELDER Germany Really a good help in the Lead Free Wave Solder
