Hi, There have been other studies where it was found that lead-free soloder joints are more reliable than tin-lead solder joints irrespective of test conditions. In fact the automotive industry has been using Sn/Ag for underhood applications for a

Japan and Europe are the main champions for the leadfee solder initiative. USA join in due to global political efforts as one of the cub scout leaderships. Military and Automobile industrial-electronics is exempt from the leadfree directive. Reason

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

We'd expect both OSP poor wetting and improper reflow recipe to show-up in more places than just this one component. But if those are the only choices, we'll go for 'wrong solder paste.' Ooops, that's not one of the choices. Ok, OK, we'll take poo

From what you are saying................If I hear ya correctly - There is no "Proctective" on the Pads (OSP, HASL....) You will be hard pressed soldering to bare copper. This can not be right. My suggestion- go polyimide with electroptical connecti

We recently have received a lot of warped (bowed and/or twisted behond IPC 600 specs.) bare boards (some our fabricator's fault, some ours by design) and I can't help but figure that long term reliability will suffer when building product with them.
