Substrate Heaters

MeiVac heaters are configured vfor two general types of applications, Samples and Wafers.

Sample blocks
may be drilled and tapped for sample holding clips. Note this is per customer specification at an additional charge.

Sample Blocks are made of Haynes Metal and MUST be pre baked at atmosphere by the customer at or exceeding the desired operating temperature prior to use.
Substrate Heaters
"Sample" Heater Block
 Haynes metal heater blocks are compatable with the Silver Thermal Paste, which is sold as an accessory by Meivac.

Wafer Blocks are Inconel metal and are wafer size specific. Wafer pockets are machined into the surface of the heater blocks

Inconel is NOT compatible with Silver Thermal Paste.

See manual or Web Site for proper preparation and care of heater blocks.
