Management Materials Manufacture
(click on the picture to enlarge)
 As the world leader in the manufacture of metal matrix composites for thermal management applications PTMS utilizes the state of the art in powder metal technology. Whether the materials are blended in house or purchased to exacting specifications, PTMS maintains uncompromising dedication to continuous improvement in its engineered materials. Composition, analysis of trace elements, particle distribution, grain size, tap density, flow characteristics are continuously scrutinized and monitored. Once released for production these materials are pressed to near net shapes. PTMS employs both mechanical and hydraulic presses in wide load ranges from 10 tons to 250 Tons. These state of the art digital presses allow fully automated operations and precisely maintain critical technological characteristics. This capability allowed PTMS to pioneer near net shape substrates out of refractory metal powders. By controlling this operation in house PTMS has the ability to be a low cost provider by strictly regulating or containing its material usage, customizing tooling shapes and reducing or eliminating machining in its production of composite substrates. After pressing, the parts are ready for sintering. PTMS has one of the largest furnace capabilities in the U.S. for sintering and infiltrating refractory composites. The company employs over 20 state of the art continuous and batch furnaces, which allow precision control of critical technological characteristics: density, microstructure, thermal conductivity, dimensional tolerance. Ceramic Manufacture  Click

These materials are then ball milled under tight process controls prior to tape casting. PTMS has over the years developed proprietary formulations resulting in consistent dimensional control to 1 percent and flatness of .003” per inch after firing. In certain product types, however PTMS can achieve a flatness of .001” per inch when necessary. Using this green tape technology as a building block, PTMS produces a variety of multilayer ceramic packages utilizing solid conductive vias for Z-axis connections as well as post fire metallization when needed to meet today’s challenges of increased I/O termination, greater circuit density and higher thermal management. With our present technology 4 x 4 arrays of multilayer structure can be produced on a routine basis. PTMS's experienced engineering team with more than sixty years of cumulative experience in high density ceramic packaging stands ready to work with our customers for the best possible product design for volume manufacturing. Plating  As
a recognized leader in high precision plating for microelectronic
applications PTMS has three state of the art plating lines.
One line is dedicated to electroless nickel and gold. Electroless
nickel or gold is a chemical reaction that enables the user to design
isolated traces in the manufacture of one’s circuitry and to
eliminate the issues regarding high current density areas on the plating
surface. PTMS also employs a state of the art high volume
automated plating capability as well as extensive use of barrel plating
for low cost solutions. In addition we have the capability of a manual
plating line that can be used for development projects, prototype
runs and very fine specifications that can be classified as “Out
of the Norm” for most plating operations. We are known for solving
those peculiar issues that occur with precise design demands.
Prototyping  Due
to the vertical integration of PTMS’s offerings, prototyping
of critical programs can be done with short lead times. This capability
offers the customer the opportunity to confirm their design integrity
before placing it into volume manufacturing. Additionally, this capability
offers PTMS the opportunity to work with its customers to
ensure high yields when high volume manufacturing is introduced. Our
engineering staff has years of experience and recognized capabilities
in assisting with the design of units down to the component level.
We take the time to evaluate and understand your project and will
make recommendations with your budget and market conditions in mind.
This will ultimately result in lower cost, higher reliability and
on time delivery.
