I think you need to call Eric and borrow his hat. Dewey -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Cedric ORAIN Sent: Wednesday, June 30, 2010 10:04 AM To: [log in to unmask] Subject: [TN] Bright tin Hello all, I've been proposed Bright Tin as PCB finishing. It is the first time I've heard about this plating for PCB. Is someone is familiar with this process and could expose drawbacks and benefit? Do you confirm that it is an electroplating process? Do I need to specify a Nickel barrier or something lie that underneath the tin layer? Is the thickness of tin is critical and has to be monitored carefully? I'm also concerned about tin whiskers with bright tin as it as been banned from the plating of connectors and components due to its propensity to the growth of whiskers. Ok, it's a lot of questions! I just want to be advised on what is important to know about that subject. Thanks in adavance for your bright advice.
