Facilities

Tecdia has access to three thin film substrate fabs; one in Japan for prototyping/R&D projects, one in the Philippines for cost-sensitive projects intended for mass production and one in the USA for enhanced features and fast lead times.
Below are generic specifications relating to thin film substrates but for detailed information about each facility, please contact us or see our design guide(s).
The Philippines: Thin Film Ceramic Substrate Design Guide
Japan: Similar capabilities to the Philippines but more support for lower volumes and novel projects.
USA: Supports planar substrates with features such as laser machined cutouts, through-hole vias, castellated vias, predeposited AuSn, etc.
