Hello, I know for sure that using lead-free technology in conventional tin-lead machines makes a lot of problems. But I wonder if we can use conventional tin-lead alloy and components with a lead-free machine! Is it possible? Does this imply any s

If you're asking about wave solder machine, yes you can run Sn/Pb in a "Pb Free" machine. The concern is that when its time to run Pb Free you're going to have to remove all the parts from the solder pot to remove all the Pn/Pb solder residue from po

Yes, it's fine - as Pete says you have to replace certain parts & either get the pot recoated or a new one. We ran a "Lead free" 6622C from Vitronics Soltec on Tin Lead, then it was cleaned up, recoated and loaded with a no-lead alloy with no proble

Hi, Im having problem on tombstone, The part is LF chip component 1005, and my solder paste is WS leded. tombstone is not in a deg angle but one side is soldered but the other side is just sitting on the solder. Looks like my solder can not wick up t

We use NC flux exclusively for SMT and wave soldering. And it is a fairly old formula from Multicore, though we are currently qualifying a new formula. The automated soldering does not appear to be a problem. It is only the hand soldering that causes

We are in the process of transitioning from OA flux to No-Clean. Because of the tighter process window there is a lot of concern about component and PCB solderability and storage. The last thing we want to do is put some solderability specification

Hi , Could DIP package ( PTH) run through IR Reflow instead of wave soldering? Will there be any reliability impact on this package. Thanks Jack

Using a flux pen sounds like a good idea. Comments are: * I assume you�re talking aqueous flux. If not, some NC flux pens leave white residues. Nearly all of 15 samples suffered to varying degrees with white residues. * Use the same flux that you

My company has been doing its hand soldering using drip bottles for application of no-clean flux. This has created quite a few problems, especially on our microwave boards. I want to convert us over to flux pens. Does anyone have any suggestions or c
