Inside semiconductor and laser equipment, long ceramic bars like this carry or separate components across a heated zone. The raised pads on the face define the only contact points, so the supported part is held at a fixed distance from the base — with almost no heat conducted and no electrical path.
Because the bar is machined from solid material, pad height, pad position and end steps are not limited by a mould. Two bars in a pair are machined to the same programme, so pad heights match within tolerance across the set.
If your fixture changes, the pad layout changes with it — revised bars are cut from new blanks without new tooling.
Form: long rectangular bar, stepped end profile, raised contact pads
Material: machinable glass ceramic (Macor-type equivalent)
Function: precise stand-off + thermal and electrical isolation
Finish: as-machined; lapped faces on request
Sets: matched pairs machined in one programme
Documentation: dimensional report on request
Raised pads concentrate load on small, controlled areas. Contact height is machined, not accumulated from stacked shims, so the stand-off is repeatable across bars and across batches.
Continuous service up to approximately 800 °C depending on environment, with low thermal conductivity (around 1.5 W/mK, where applicable) and high dielectric strength — heat and voltage both stop at the bar.
No firing after machining means no shrinkage compensation. Pad positions and step heights can be revised between batches, which suits fixtures that evolve during development.
