Electrovert's corrosion tests show that it's less corrosive to SS than SAC but it still exhibited corrosive characteristics. What they can't tell from the tests yet is how long before the corrosion starts with the alloy. To be 100% sure, Electrover

I am based in New Zealand and studying towards an MBA from Henley Management College in the UK. My current project is for a sheetmetal fabricator, on the feasibility of constructing their own in-house electroplating plant. The client specialises in

Your plater's recommendation should work fine. Your simple copper plate will work, but you'll be stepping into fighting a copper tarnish battle. Silver over the copper is a better choice. I was thinking a silver thickness of a minimum of 3 microns

I have a right angle male shrouded connector and the whole set of termination leads is tin lead plated, at least 100 microinches thick. Should the entirety of the lead be conformal coated? Or can we have just the joint coated? I know I have coated le

Bare inconel is NOT ment to take solder, because * Nickel develops a tenacious oxide layer that is very difficult to remove since the nature of the oxide is very dense, coherent, etc. * Chromium is difficult to solder. * Iron is difficult to solder.

Few of us here on SMTnet fabricate our bare boards. Most of us are assemblers. So, the solderability of the connections of our boards is a BIG issue with us. Our suppliers protect the solderability of the copper by coating the copper to limit the

Sounds like hyper-corrosion of nickel, commonly referred to as 'black pad', in ENIG solderability protected boards. Search the fine SMTnet Archives to get started. Additionally, the July - September 2002 'Journal Of Surface Mount Technolgy' has an

Most ovens I know use oil to lubricate conveyor chain, not grease. Anyway, is this what you're using: NMG No Melt Grease NLGI 2 (operates from -20�C to +270�C) NMG is a long-fibred highly adhesive grease which does not melt or drip at high temperat

During soldering, the gold dissolves into the solder connection. You solder to the nickel. The gold protects the nickel from oxidation. Corroded nickel is very difficult to solder. So if your gold is thin, it may not protect the nickel from corrosion
