Quadrant EPP Announces New Advanced Material for Electronics Test Applications

Semitron® MDS 100 Combines Remarkable Strength and Stiffness with Extremely Low CLTE and Low Moisture Absorption

(Reading, PA - July 15, 2008) - Engineers and designers of equipment that require pre-cise, reliable tolerances will have more options for new or upgraded part designs with Quadrant's new Semitron® MDS 100 machining stock. Semitron MDS 100 is a strong, stiff platform for applications such as:

o Test sockets for semiconductor test and package equipment
o Fixtures for electronics testing
o Mounting points for precision diagnostic equipment
o Positioning platforms for miniature motion control device

With a Flexural Modulus (ASTM D790) in excess of 1,400,000 psi and extremely low moisture absorption (24 hr., ASTM D570) of .10%, Semitron MDS 100 delivers performance that solves engineering problems associated with uncontrolled application environments. Its low Coefficient of Linear Thermal Expansion (ASTM E831) of 1.1 x 10-5 also contributes to its remarkable stability. The Heat Deflection or softening temperature (ASTM D648) is 410° F (210° C) At SemiWest, the world's largest semiconductor manufacturing tradeshow Fred Sanford, Global Advanced Materials Business Line Manager commented "We're very pleased to deliver such a promising material to a market that has a clear need." Sanford also com-mented "Our Torlon® PAI machinable shapes are the industry standard for test sockets and many other electronic devices, and we anticipate this new Semitron MDS 100 material being a perfect complement".

Semitron MDS 100 sheet is available from stock in range of thicknesses from 1 mm to 6 mm (.04 to .236") in sheet sizes of 250 mm x 250 mm (9.84") and 500 mm x 500 mm (19.68"). Other thicknesses are possible.
