Stanna-Q ® is an engineered solution for the production of quad flat, no lead components. Because Stanna-Q ® is an electroless process, bussing for electrolytic connection does not need to be engineered into the strip or carrier. The singulation process necessitates an optimized pretreatment and active bath to ensure total flank coverage. The process is specifically developed to cope with both dicing and punching singulation methods. Stanna-Q ® is guaranteed to produce three dimensional solder joints resulting in maximum reliability in the field and yields in production.
