Solder Printing 2x2 inch ceramic Substrate | 15 February, 2007

Hi All, I was wondering if anyone has experience of printing solder paste on to 2x2" ceramic substrates.. At present we are using a very old de haart printer with a mesh emulsion screen.. I am looking to replace this with a more reliable modern piece of equipment.

Does anyone have experience in this field or can maybe recommended an equipment manufacturer for such an application ?

Many Thanks

Phil

Phil,

I used to print solder paste on 2" X 2" and 3" X 3" 96% Alumina substrates all the time. I used standard solder printers and stencils. Screens are difficult to use and don't print well. You can use a stencil on a DeHart, CW Price, or AMI Presco thickfilm hybrid printer also. I used semi auto Dek 249, semi auto SMTech 100MV, and fully auto Dek 265 printers. I used a pallet to transport the small substrates on the Dek 265 conveyor. I believe my pallet was about 5" X 5". I used a vacuum box that mated with the pallet at time of print. Honestly, taping the 2" substrate to the pallet works fine. It is just ugly and low tech. Lots of people print ceramic substrates with fully auto and manual solder printers. It is straight forward and any solder printer manufacturer can help you out.
