Well, it finally happened. A machine Operator did not follow our bar code process and "grabbed a tube of solder paste" and guess what. Built 250 assemblies with LF paste when it should have been Tin/Lead!!!! SOLDER PASTE SUPPLIERS: can you make t

Can anyone tell me what makes the wave solder machine lead free? I I am looking to buy a used machine "electrovert minipak 300" and they are claiming that they can convert the machine into lead free. I want to know what does involve to do this kind o

Lead-free means expensive tin. Tin is an excellent solvent. So, metal parts in contact with molten tin must be expensive enough to resist that nature of tin. To learn more about this: * Search the fine SMTnet Archives * Look here: "Liquid Tin Corrosi

Could you tell me please when the lead free solder regulation will become mandatory in Europe and also what are the current industrial alternatives for paste, bar and wire. Cheers, Jack

I want to know the advantage of using complete inert soldering wave machine (with Nitrogen, Tunnel concept) in comparison to use just a soldering machine withe inerted solder pot. Thanks

The biggest fear is mixing the solder pastes and bar solder. Had a training program for teaching folks what the alloys are and how to read them. I have locked up the bar solder and use the buddy system to restock the pot. Put up many signs on le

yeah I’ve tried to go down the road of internal recycling but the company carnt justify spending 20k on a machine that does it. Ah but where still onto it in other places though our SMT department has very minimal wastage on solder paste as we have b

easier if you recycled on-site? You can still send off for reclaimation the oxide powder that your left at the end of the process. Failing that talk to your supplier to see if they have arrangements to do this for you or look at reducing dross - i f

Instead of a minimum thickness, we require no exposed copper or SnCu intermetallic. We've been having a lot of trouble lately with suppliers of SN100 HASL boards giving us pads with very irregular solder deposits with areas of exposed intermetallic.
