Semitron ESD 225
SEMITRON ESd 225 is an acetal based static dissipative material ideal for material handling applications. It avoids discharge problems for parts intended for human contact.
SEMITRON ESd 225 is also an excellent choice for fixturing used for handling in-process silicon wafers or used in the manufacturing of sensitive electronic components including hard disk drives and circuit boards.
Profile
- Permanently static dissipative
- Dissipate static charges (5 kV) in less than 2 seconds per mil-B-81705 C
- No metals or graphite / carbon powder used
Applications
- Wafer combs
- Wafer combs made of SEMITRON ESd 225 eliminate transfer equipment discharge problems that cause thousands of lost wafers every year.
- Handling trays
- IC handling trays manufactured from SEMITRON ESd 410C dissipate static charges reliably and are dimensionally stable.
- Inserts
- Static dissipative SEMITRON ESd 500HR inserts reduce damage to sensitive devices due to static discharge.
- IC Device Testing Fixtures
- A test fixture manufacturer recently began using Semitron® ESd 520HR that combines electrostatic dissipation(ESd) and high mechanical strength, to make integrated circuit test heads. The high mechanical strength of SEMITRON ESd 520HR results in longer useful life of the test heads and, therefore greater units (tested) per hour. SEMITRON Esd 520HR is the first product to reliably meet all physical performance needs for test nests, sockets and contactors, combined with ESd performance. It is both ESd (surface resistivity of 1010 to 1012 ohms/square) and has sufficient resistance to minimise the risk of 'leakage' (cross talk). Also significant is the ability of SEMITRON ESd 520HR to retain its surface resistivity at electrical forces greater than 100 volts.
