METALLIZED SUBSTRATES, PACKAGES AND COMPONENTS WITH PCTF® TECHNOLOGY

Remtec has developed and commercialized an enabling packaging technology by combining standardThick andThin Films with copper plating, advanced materials and proprietary manufacturing processes. The Company’s core PCTF® technology addresses a broad array of power applications across a large number of various industries.

Remtec Inc. has developed and commercialized a proprietary process for manufacturing cost effective metallized ceramic substrates, chip carriers, packages and specialty components based on PCTF® metallization –Plated Copper on Thick (Thin) Films. PCTF® technology provides an enabling solution oftentimes not achievable with either conventional thin or thick films or co‐fired ceramics. This cost effective technology is extremely versatile. In addition to its basic copper plated metallization (25 / 125 µm thick),  there are added value features such as plated through holes, solid plugged metal vias, castellations and integrated, wide rang thick film resistors and multilayers.

Current Carrying Capacity
Using plated copper metallization from 25 µm to 125 µm thick, on a thermally conductive ceramics combined with copper plated thru holes  and plugged vias with low dc resistance ≤ 1mΩ allows high current capacity in excess of 50 Amps as well as excellent heat spreading and low thermal resistance.

Thermal management improvement
Plated copper metallization on Alumina, AlN and BeO  as thin as .010”, with thermal vias (K≥250 W/°CxM), plated through holes and plated‐up heat spreaders provides  low thermal resistance (Øjc) of below 1°C/W, and serves as a  thermal management  solution.

Innovative ceramic Packages
A combination of solid metal, thermal vias (k ≥ 200 W/(MxOC) with low dc resistance of 1mΩ that are hermetic to (10‐8 atm cc/s) and wraparounds for SMT attach allows design and fabrication of leadless hermetic packages, flip chip carriers and interposers.

Increasing circuit density in a miniaturized package
Using Remtec’s PCTF® technology, designers can combine fine lines (50 µm) and thick copper plated “wires”. In addition, conductor multi‐layer patterns (up to five layers), small size printed thick film resistors (

PCTF ® circuitry operates at a wide frequency range
Remtec’s metalized ceramic substrates have been successfully field‐tested to frequencies up to mm range with low losses, often replacing costly thin film circuits without sacrificing performance. PCTF technology incorporates etched fine lines, transmission lines, RF resistors, and efficient signal and ground connections.

PCTF ® circuitry assures high assembly yield
Tin, Nickel, and Gold (electrolytic & electroless) finish over bare copper allows for excellent soldering, wire bonding
(aluminum and gold) and eutectic die attach.  Remtec’s metalized substrates, chip carriers and packages are compatible with advanced electronic assembly techniques. Our substrates withstand multiple soldering operations, assure excellent solderability, exhibit no solder leaching and are suitable for various interconnect techniques: SMT, gold and aluminum wire bond, epoxy die‐bond, flip chip attachment and high temperature die‐attach.

PCTF ® Reliability
Remtec’s metalized ceramic substrates (fully‐assembled) withstand thermal cycling from ‐65o C to 150o C (more than 1000 cycles) and other MIL‐STD‐883C testing without the loss of adhesion as well as via integrity and hermeticity. In addition, Remtec’s substrates have qualified for space (Class H & K), military and biomedical applications.
