Research on Applying Direct Plating to Additive Process for Printed Ciecuit Board

摘要

The feasibility of applying direct-metallization as an additive process for printed circuit board was explored. Pd/Sn catalyst was used in the activation step and the content of Pd adsorption was found to be the controlling factor. The Pd content was affected by the conditions of various steps including condition, activation, acceleration, and promotion.
