Our two component suppliers use 99.5Sn/0.5Cu and 97Sn/3Ag solder (respectively) for tinning their leads. We use 98.9Sn/.66Cu/.33Ag solder in our wave solder machine. Is there any significant advantage to either tinning process regarding solderabili

My policy is not to mix them. You have zero cross contamination potiental with this policy.

I don't think that you would need to test these. Have you ever seen any evidence of solder sticking to them? We use the same material and never notice anything besides flux staying on the bottom. Would the lead absorption if any even be of a concer

Hi everybody, We have wave solder fixtures made of Durapol and multiple wave solder machines. Most likely we�ll use the same pallets for either tin-lead or lead-free solder for a while (of course after washing the pallets). Should we test the palle

We have passed testing using this process, I would consider it on a case by case basis however. We are very careful about the quantity of the O.A. that we use. The water soluble flux is gone after cleaning unless it was/could be encapsulated or tra

Need some input here..... The fear is that the if we use water soluble flux at the repair operation, that the no-clean encapsulation will capture some of the organic material as it cools down and goes to its original state. The organic material wil
