Weymouth --On Nov. 25, DEK held a Stencils Technology Day at its Weymouth, UK, office to share the findings from its recent lead-free print trials, and to provide hands-on experience with stencil technologies.

Clive Ashmore, global applied process manager, presented the lead-free trial results. The company found that having a stencil that is well designed and specified for its application has the greatest impact on process performance, whether the application is lead-free or leaded. A second important consideration is materials composition. Electroformed nickel was the top performing stencil material in tests, closely followed by laser-cut nickel.

Richard Boyle of Henkel Multicore then gave a presentation on lead-free pastes that focused on areas where the differences between leaded and unleaded may impact the industry most.

The afternoon was dedicated to workshops and discussions on the theme "Print failures: cause and effect."
