Subject: [TN] Seam welding

I'm creating  instructions for design engineers, purchasers and
operators 
about seamwelding MCM packages. About AlSiC ones, electroless Nickel is 
preferred by experts around. However, I mean electrolytic Nickel minimum
5um 
is better. I have tried Sulfamate halfbright on both lid and package.
Lids 
are typically 0.5 mm thick with 12% Si added. However, I've no 
recommendations for wheel angle.Anyone who got experience? 5, 10, 15
degrees 
or what? Machine makers have nothing on AlSiC.
