Developing new solutions harnessing ceramic and RF technology.
Yokowo’s ceramic substrates and antennas, sold the world over.
With the Low Temperature Co-fired Ceramics (LTCC) and High Temperature Fired Ceramics (HTC) technologies at the core, Yokowo offers LTCC substrates and compact and high-performance ceramic antennas to enable high-density wiring, compatible with compact, low-back and RF devices.
LTCC (Low Temperature Co-fired Ceramics): Ceramic Substrate
Substrates for use in the wafer level CSP and camera module sector increasingly require high-density, high-precision pattern formation and flatness. In the field of semiconductor testing equipment, it is necessary to increase the size of the Substrate. Yokowo harnesses cutting-edge LTCC processing technology and 3D RF design technology to offer its customers products that meet their needs precisely.

Camera Module Substrate
3-D RF Design
Using a circuit and electromagnetic field simulator, Ansoft Designer and HFSS, Yokowo provides circuit design and three-dimensional RF design for antennas, filters, RF module substrates and others.
Interposer Substrate for Semiconductor Wafer Test
An LSI semiconductor wafer can have thousands of densely aligned bonding pads. LSI testing cannot be performed without a prober for physically expanding the narrow pitch pads of the semiconductor to connect them to the tester. Based on its advanced LTCC processing technology, Yokowo has successfully developed an interposer substrate that plays a central role in the prober. Together with its vertical micro precision probe, Yokowo will respond to sophisticated demand from the semiconductor wafer sector.
HTC (High Temperature Fired Ceramics): Ceramic Antenna
In line with the decrease in equipment sizes, demand for compact antennas utilizing the high conductivity of ceramics has increased. Yokowo has developed and supplied these antennas through comprehensive processes that range from material development to base material sintering and element formation.
