VC America Sumitomo Packages

Ceramic Chip Carrier for SMT Applications

Sumitomo is the world’s largest ceramic producer and third largest electronics packaging company. We supply ceramic chip carriers for SMT applications. These state-of-the-art designs enable compact high performance and reliable operation designed in ever smaller package sizes

Design Support

We have fully integrated CAD systems for developing package designs and implementation into manufacturing. Modeling can be performed to evaluate parasitic values, thermal dissipation analysis, mechanical stress, etc. We have excellent soft tool, semi-hard and hard tool levels for production packages. Electrolytic process solutions are available for many standard current products. Electro-less process solutions are also available for newer high frequency applications. Package sizes include the popular 5x7mm, 5x3.2mm, 3.2x2.5mm, 2.5x2.0mm, 3.8x3.8mm sizes, and smaller sizes to 1.6 x 1.0 mm are being proven now. Special sizes are also available, including larger than 5x7, however, SMIED does not support the 9x14mm package types. Contact us for more details.

Product Features

Packages have high hermetic properties and great heat-resistance characteristics due to the use of Alumina ceramics as its material.

Applications

Crystal resonator, Crystal oscillator, TCXO, SAW filter, and various Hybrid packaging applications.

Sealing methods

Available for seam weld, Au/Sn, glass, solder, electronic beam, direct seam.

For glass and solder sealing a ceramic lid is also available.
