Tecdia's wire bondable single layer chip capacitors (SLC) and resistors are made in Japan with proprietary formulations of ceramic materials, with a relative permittivity (dielectric constant) ranging in value as low as 40 and high as 50,000. Single layer ceramic chip capacitors and resistors used in microwave and optical communications devices are generally die attached to a circuit board or substrate using conductive epoxy or gold-tin solder, and the opposing electrode(s) connected to other elements of the circuit by gold wire or ribbon bonding. Some designs can be entirely surface mounted (flip chip) to eliminate wire connections.
The impedance characteristics of single-layer capacitors and resistors are superior to multi-layer capacitors for high-frequency bandwidths.

Ceramic Microwave Ground Blocks Tecdia ceramic microwave grounding block

Alumina (aluminium oxide) ground blocks (also called mounting shorts) are customizable conductive shims ideal for micro-assemblies in both optical and microwave industries. They are being used to raise the ground level for shorter wire bonds to ground or - if attached with non conductive epoxy - as an isolation pad to land the wire bonds on and off to shorten wire bonds.
