Semitron® MP 370

• Semitron® MP 370 offers more choices in the design and manufacture of precision test sockets for the semiconductor manufacture industry.  While maintaining the same excellent moisture absorption and high thermal resistance of PEEK, Semitron® MP 370 provides greater strength and dimensional stability.  This custom formulation allows finer and cleaner detail due to it's excellent machinability.

Product Overview.

• Very low moisture absorption
• Exceptional 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

 Engineering Notes.

It is important to know how applied voltage affects the resistance of a material. Some materials exhibit high resistance at low voltages, but when subjected to harsher conditions, they can fall. This is due to dielectric breakdown and is irreversible. This chart illustrates the effect of sequential applications of 100 through 1,000 volts, then a return to 100 volts to determine the hysteresis. Since static electricity can be several thousand volts, consistent performance across the voltage range must be considered.

Some materials are very inconsistent and vary on the "grain" of machining. One pair of lines illustrate the typical variation from side to side (A to B) of the same sample. This example demonstrates the need for consistent behavior in service.
