Can anyone give me a ballpark figure on where to set the temperature for the pre-heaters of a wave solder? Any responses are greatly appreciated.

Jason, it looks like you have several options that have strong promise of working. I suggest you perform a designed experiment to find/optimize the best solution with these suggested approaches. Ron

What is the best or ideal cleaning method for wave solder pallets? I have been using iso prop and am not sure if this is the cause for having brittle wall material. I wouldn't think alcohol would degrade the durastone material. Most of my pallets hav

I' designing a PCB with SMD components to optimize the land patterns for wave soldering. I find that the IPC-SM-782 land patterns are not robust enough for wave soldering, yielding ramdom skips and bridges. This PCB will also give me insight on sha

Bob, Great theory if you're selling SN100C, but I have to disagree that an alloy being 4�C off eutectic will cause cracks. When a solder joint exits the solder wave, there is an immediate drop in temperature of 100�C. so being off 4�C is irrelevant.

IPC-A-610D Section 5, shows a variety of photographs of: * Good lead-free solder connections * Lead-free soldering anomalies Hot Tear / Shrink Hole is one such anomaly. This shrinkage effect appears primarily on wave-soldered joints, but can also

I've seen some plastic fingers advertised for wave solder machines. Anyone used 'em? They are 'glass-reinforeced polymer resin', they are supposed to stand the heat, can be mixed with titanium fingers on the machine, and cheaper! (near and dear to

Anyone have a good source for respirators, gloves, aprons etc. for working on wave solder machines? Is there some industry standard for what is required?

Dear all, We observed visible micro crack at top side of solder fillet during lead free wave solder process. We did not see any visible micro crack at bottom side, and it always located at joints of transformer. Any input be much appreciated. Best
