HomeSemitron® ESd Overview
Semitron® ESd Overview
OVERVIEW
The Semitron® ESd family of static dissipative products was designed by Quadrant for use where electrical discharge in operation is a problem. They are commonly used for sensitive electronic components including: integrated circuits, hard disk drives and circuit boards. Semitron products are also an excellent choice for material handling applications, and components in high speed electronic printing and reproducing equipment.

Semitron® ESd products are inherently dissipative and electrically stable unlike many other ôdissipative" plastic shapes. They do not rely on atmospheric phenomena to activate, nor are surface treatments used to achieve dissipation. Static electricity is dissipated through these products as readily as it is dissipated along the surface. All of these products dissipate 5 KV in less than 2 seconds per Mil-B-81705C.
  • Available from USA, Singapore and Taiwan stock.

    Semitron® ESd 225 Static Dissipative Acetal
    Semitron® ESd 225 is ideal for fixturing used in the manufacturing of hard disk drives or for handling in-process silicon wafers. It is tan in color.
  • Surface resistivity: 10*10 - 10*12 ohms/sq.
  • Thermal performance to 225°F (107°C)
  • Good wear resistance

    Semitron® ESd 410C Static Dissipative PEI
    Semitron® ESd 410c is ideal for handling integrated circuits through the test handler environment. It is black in color and opaque.
  • Surface resistivity: 10*4 - 10*6 ohms/sq.
  • Thermal performance to 410°F (210°C)
  • Low stress for tight tolerance machining
  • High strength and stiffness

    Semitron® ESd 420 Static Dissipative PEI
    Semitron® ESd 420 is the only, truly dissipative plastic product for use in high temperature applications.
  • Surface resistivity: 10*6 - 10*9 ohms/sq.
  • Thermal performance

    Semitron® ESd 480 Static Dissipative PEEK
    Semitron® ESd 480 is static-dissipative, carbon fiber reinforced PolyEtherEtherKetone for use where the properties of PEEK are needed, but protection from static discharge is a requirement. This material is available in sheets and rods and is black in color. Semitron ESd 480 has a surface resistivity of 13 10*6and 1 X 10*9Ù/sq, but its heat-deflection temperature is 480°F. Its chemical resistance makes it suitable for wafer handling and other structural applications in wet process tools where static dissipation is important.

    Semitron® ESd 500HR Static Dissipative PTFE
    Reinforced with a proprietary synthetic mica, Semitron® ESd 500HR offers an excellent combination of low frictional properties and dimensional stability. Semitron® ESd 500HR should be considered wherever Teflon* PTFE is used. It is ideal for applications where controlled bleed off of static charges is critical. It is white in color.
  • Surface resistivity: 10*10 - 10*12 ohms/sq.
  • Thermal performance to 500°F (260°C)
  • Thermally insulative
  • Very low coefficient of friction
  • Broad chemical resistance

    Semitron® ESd 520HR Static Dissipative Machining Stock
    Semitron® ESd 520HR has an industry first combination of electrostatic dissipation (ESd), high strength and heat resistance. This new ESd material is ideal for making nests, sockets and contactors for test equipment and other device handling components. The key features of 520HR are its unique ability to resist dielectric breakdown at high voltages (>100V). The graph below demonstrates the electrical performance of plastic materials commonly used in automated test handlers. Typical carbon fiber enhanced products become irreversibly more conductive when exposed to even moderate voltage.
    Only Semitron® ESd 520HR maintains its performance throughout the voltage range, while offering the mechanical performance needed to excel in demanding applications.
  • Surface resistivity: 10*10 - 10*12 ohms/sq.

    Semitron MDS100
    Semitron® MDS 100 has a remarkable combination of strength, stiffness and stability. It was developed to be used in uncontrolled application environments or where a high level of precision is required. It is an ideal choice for semiconductor test sockets, nests and fixtures in test and package equipment.
  • Moisture absorption of .10% at 24 hrs. (per ASTM D570).
  • Thermal performance to 410°F (210°C)
  • Flexural modulus > 1,400,000 psi
