SAN JOSE, Costa Rica, Jan. 5 -- A pair of suppliers of electronics materials and equipment will team to deliver a one-day seminar on lead-free manufacturing here later this month.

On Jan. 19, DEK, a provider of screen printers, and Kester, a supplier of solder materials, will  cover new lead-free alloys, wave soldering, reliability and the global impact of compliance.

Technical papers including "Effects of cooling Speed on Microstructure and Tensile Properties of SnAgCu Alloys" and "Chip Scale Package Rework Considerations: Using Solder vs. Gel Flux" will also be presented, and the impact of lead-free on screen printing will be addressed.

While many courses leave out any discussion of Pb-free's impact on mass imaging, recent research conducted by DEK has shown that paste application method (squeegee vs. enclosed head), stencil material, stencil manufacturing method and machine accuracy all have a tremendous impact on the successful implementation of lead-free manufacturing, the companies said.

The seminar will take place at the Melia Callari Hotel. For more information or to register contact Craig Brown, DEK Americas general manager, at 908-782-4140, x 226.
