The PR Hoffman 2400 Lapper is a lapping and polishing machine. The 2400 is categorized under CMP (Chemical Mechanical Planarization).[1]
What it is
How it works
General reference — not yet source-verifiedA lapping and polishing machine removes small amounts of material with an abrasive interface between the workpiece and a rotating or reciprocating lap or platen.
CMP-class lapping equipment is used to flatten, thin, and improve surface finish by controlled mechanical abrasion.
Where it fits in the process flow
General reference — not yet source-verifiedThe PR Hoffman 2400 Lapper fits in finishing and planarization steps after earlier shaping or thickness-reduction operations.
The PR Hoffman 2400 Lapper is used before downstream inspection, cleaning, or subsequent processing that depends on a flatter and smoother surface.
Applications
General reference — not yet source-verifiedThe PR Hoffman 2400 Lapper is used for CMP-related lapping and polishing work on precision substrates and other flat workpieces.
The PR Hoffman 2400 Lapper suits applications that require controlled surface correction, planarity improvement, and finish refinement.
