'QuickTurn' prototyping capability available for high thermal conductivity, controlled expansion, lightweight alloys

Osprey Metals, suppliers of controlled expansion Al-Si and Si-Al alloys (Osprey CE Alloys) for use in the electronics industry, has established a 'Quick Turn' prototyping service for machined components.
|

Typical machined parts include enclosures, carrier plates and other critical items used in the manufacture of RF, microwave, opto-electronic and power devices and other microelectronic products. Depending on quantity and configuration, CE alloy machined parts can be delivered in as little as 2 weeks from receipt of drawings, whereas simple blocks and plates can be shipped from stock within 2-3 days.
What has made this possible is significant investment in Osprey's UK downstream processing which now includes multi-blade saws, OD diamond slicing and vertical machining equipment. Parts can be supplied with an electroplated surface.
At the same time, Osprey Metals has announced that it is expanding its network of representatives in the US. The company recently announced the addition of Advanced Packaging Associates (APA) to its North American customer support team.
APA, head quartered in La Jolla, California focuses its efforts mainly in the Western US but provides its consultancy services for Osprey CE Alloys to customers throughout North America. APA joins InterTronic Solutions Inc, (Canada and USA), BWS Microwave Marketing Inc. (SE States) and Vanguard Electronics Corporation (New England States) in providing representation for Osprey controlled expansion alloys in North America.
Osprey's full range of five CE alloy grades, which includes the CE7 (7ppm/°C) and CE9 (9ppm/°C) grades can be processed and are available for 'quick-turn' prototyping. These alloys, tailored to match closely the expansion coefficients of typical microelectronic substrates and devices, such as alumina circuit boards and GaAs devices, have exceptional stiffness and thermal stability, and typically offer significant cost savings over competitive materials, such as copper tungsten (CuW) and aluminium-silicon-carbide AlSiC. The CE11 and 13 alloys offer further cost advantages in applications where a higher CTE is required or can be accommodated; eg small alumina substrates with compliant adhesive attachment. A low cost CE17 (17ppm/°C) grade matches the CTE of most common organic substrate materials, such as FR4 board, but it is approximately one third the weight of copper, which is the conventional carrier plate material for these substrates.
Osprey Metals is a wholly owned subsidiary of Sweden's Sandvik AB, a high technology engineering group.
