Semco E-Chucks
Global Clamping Solutions


SEMCO has developed a full range of ESC capable to cover the entire
temperature range from cryogenic temperature up to 650°C
Moreover our ESC offer :
  • A ROBUST DIELECTRIC MATERIAL - Hardness =7.0 Mohs
790 Kg/mm² Vickers (HV10) / 850 Kg/mm² Vickers (HV20) / 530 Kg/mm² Knopp (200g)
               For Ref: Diamond = 10  Mohs     Si or  Quartz = 7.0 Mohs     Glass ≥ 4.5 to 6.5 Mohs
               Mohs scale of mineral hardness characterizes the scratch resistance of various minerals
               through the ability of a harder material to scratch a softer material.
A HIGH  DIELECTRIC STRENGTH : 4.5 kV 
Max operating recommended voltage :  ± 1 kVdc
AN ESC CAPABLE OF BEING CLEANED AND REWORKED
A LOW MTTR ( Mean Time To Replace)


FOR  SEMICONDUCTOR OR INSULATING  SUBSTRATES
Typical BSG LUR @ 1000Vdc
on bipolar ESC is  < 1sccm
