1900 Double Sided Lapper
What it is
General reference — not yet source-verifiedDouble sided lappers are material removal and surface finishing tools. Double sided lappers process opposite faces of a workpiece at the same time between opposing plates with slurry or abrasive media. Double sided polishers and lappers are used when flatness, parallelism, thickness control, and surface finish matter to downstream handling or device fabrication.
How it works
General reference — not yet source-verifiedDouble sided lapping and polishing machines hold parts in carriers between an upper plate and a lower plate. Relative motion between the plates, the carriers, and the abrasive interface removes material from both faces at the same time. Process results are influenced by plate condition, slurry or abrasive choice, pressure, motion, and time.
Where it fits in the process flow
General reference — not yet source-verifiedDouble sided lapping and polishing sit in process flows where a substrate or component needs both faces finished before later precision steps. The class is used after slicing, pregrinding, or another bulk shaping step and before cleaning, inspection, bonding, coating, or device patterning. The class is relevant in semiconductor and precision optics work where geometry and surface condition affect subsequent process stability.
Applications
General reference — not yet source-verifiedDouble sided lappers and polishers are used for wafers, discs, substrates, and other flat components that need simultaneous two-sided finishing. The class is applied to processes that seek improved flatness, parallelism, thickness uniformity, and surface quality across brittle or hard materials.
