The PR Hoffman 1500 66 T Double Sided Lapper is a double sided lapper/polisher. The PR Hoffman 1500 66 T Double Sided Lapper is categorized as CMP.[1][2]
What it is
General reference — not yet source-verifiedA double sided lapper is a material removal and surface finishing machine. Double sided lappers process both faces of a workpiece at the same time between opposed plates. CMP-class finishing equipment is used where flatness, thickness control, and surface condition matter to downstream manufacturing.
How it works
General reference — not yet source-verifiedDouble sided lappers operate by holding parts in carriers between an upper plate and a lower plate while abrasive action removes material from both sides. Lapping and polishing processes use relative motion, pressure, and slurry or abrasive media to improve planarity and surface finish. Double sided configurations are used when both faces need to be processed in a balanced manner.
Where it fits in the process flow
General reference — not yet source-verifiedDouble sided lapping and polishing tools sit in the surface preparation and precision finishing portion of a manufacturing flow. Such tools are typically used after slicing, grinding, or other shaping steps and before cleaning, inspection, bonding, coating, or device fabrication steps that depend on controlled surfaces.
Applications
General reference — not yet source-verifiedDouble sided lappers are used for precision finishing of wafers, substrates, disks, and other flat workpieces. Such equipment is applied where both sides of a part need improved flatness, parallelism, thickness uniformity, or surface finish. Lapping and polishing tools are also used for brittle and hard materials that require controlled abrasive removal rather than simple cutting.
