Glass wafers, glass-ceramic plates and glass substrates for through-glass-via (TGV) process development.
What to specify
Glass composition, thickness, hole state, flatness, warp, surface damage and cleaning. Separate pre-via polishing from finishing an already perforated substrate.
Made-to-order consumables
Carrier geometry and material, plate grooves, pad contact properties, conditioning, cleaning and polishing media are reviewed for the actual process. Drawing review and first-article support establish the repeat-order specification.
