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

Hi All, Does any body have any information on hot bar lead free soldering ? Need papers or experimental data ASAP Thanks

Yes of course. The leg of the component breaks between the top of the solder joint and the component body. We can induce the same failure mode with lead free joints but usually after 10x longer on vibration.

I am Just starting to explore the Pb free soldering processes. It sounds like you have been involved for some time. I have a million questions, do you have contact info that I could use to discuss off line? Thanks

I hear ya Ray, but I have standard (automatic) solder dispenser that are 700gram modules. Jars have other issues that I have migrated away from... I like your idea of slaving the paste bar code label to the board scanner....

What is the difference of formulation No-Clean Sn63 with No-Clean lead free paste? Is there techniocal data in detail for performance property of No-Clean lead free paste (for example, viscosity, solderability, tack, print life, reflow profile)? Is

We are performing testing for lead free connector finishes. We want to run solderability tests on a series of lead free connector plating options in a series lead free PCB's. I need some advice on the most popular lead free PCB finishes. I am aware

We have done some trials with Lead free which appear to have gone well. We will be introducing a number of new products over the coming months and it is an opportune time to begin using lead free on these products which will be required by law in the
