BeCu is not solderable without plating Cu, Sn, Ag, Ni etc. The solder joint will only be as strong as the bond strength of the solderable plating to the BeCu Pat

Zinc from the brass [Cu3Zn2] diffuses into the tin causing solderability problems. Just 0.001% of Zn in your solder can render it fit for the scrap heap. So, you need a barrier plate between the brass and the tin. Copper or nickel-plating is commonl

Hello, I am looking for some advice please about how to go about plating some brass pins for a new assembly. (which will be hand soldered) I have spoken to a couple of "experts" who seem to contradict themselves.. Firstly what should I be solderin

Is there a preferred method among printed circuit board assembly for accurately and quickly verifying the copper weight of a printed circuit board? I would like a tool and process that our quality inspector could quickly use to verify upon receipt of

Pure (red) copper oxide is green, its not a residue its just oxidation. In your case water and heat will accelerate the oxidation process of unplated or unprotected pure copper. The best way to avoid this from happening is use a socket with tin or n

We are having solder fillet finish issue. The solder looks like rough solder on the connector leads .The plating of the leads is Nickel (99.9% purity) and the PCB plating is imersion gold. I have tried fine tuning my reflow profiles an have used N2 i

Questions are: * What is the current plating on the connector that is over the "plating of the leads is Nickel (99.9% purity)"? * What are the temperatures and durations at those temperatures that you read on these connector leads? * What solder allo

Hi, The ROHS compliant parts are usually Matte Tin on the outer terminal plating. There are also 2 further types of metal on the average chip cap - the undercoat metal of the outer electrode & the inner electrode. These are usually the same & are
