Masks for Lead Frames

We manufacture masks that are used during the plating process for covering up the parts of lead frames (thin metal plates used in semiconductor packages such as ICs and LSIs) to create stripe-patterned plating.
Lead frame production methods are changing in various ways, such as larger sizes, matrix configuration, barrel-plating, and so on. Along with this, higher quality and precision are required on the masks using for plating. ASK Holdings has been involved in creating masks for lead frame plating for over 30 years, under the motto such as “high quality”, “quick delivery”, and “low cost.”
