GENERAL PROPERTIESSemitron® MP370 was developed to offer new material options for the design and manufacture of precision test sockets for the semiconductor manufacturing industry. It offers significant performance advantages over unfilled PEEK while maintaining the moisture resistance and high thermal performance that makes PEEK an attractive material choice.
Specifically, Semitron MP370 gives the designer a machinable platform that has enhanced thermal resistance, toughness and higher strength performance versus unfilled PEEK. This custom formulation offers the next level of performance without the failings of injection molded blanks (high internal stress, inconsistent properties) or traditional ceramic-filled materials (poor machinability).
Semitron® MP370 is WHITE in color and available in several thicknesses of sheet or plate only.
- Very low moisture absorption
- Excellent machinability - very small holes and tight hole patterns are possible
- Strength and stiffness that exceed unfilled PEEK materials
- Low internal stresses and no "soft center" problems associated with injection molded blanks
- IC test sockets for semiconductor manufacturing equipment
- Structural parts in electronics and telecom equipment
- Insulating blocks and fixtures in diagnostic equipment
