This alumina ceramic block carries a dense, precisely positioned grid of small holes on its working face. Rows of pins, leads or probes pass through the holes and stay exactly where the process needs them — the ceramic body holds every hole position rigidly, does not conduct, and keeps its dimensions at temperatures where plastic positioning plates warp and metal plates short circuits.
Because the block is drilled and ground from sintered alumina instead of pressed in a mould, the hole pattern is not fixed: pitch, hole diameter, row offsets, chamfers and wall thickness all follow your drawing. Edge chamfers are ground so the block handles cleanly and seats flat against its mounting surface.

Haorui Industrial has machined non-standard advanced ceramics since 2006 (ISO 9001). Send us a 2D drawing (PDF/DWG) or a sample: we quote with tolerance and material recommendation, produce 1–10 piece prototypes in 7–15 days, and keep the process data for repeat batches. Materials available: 95% / 99% / 99.5% Al2O3, ZrO2, Si3N4, SiC, AlN, macor.
Yes — the grid is drilled from your 2D drawing or DXF file, so pitch, rows, offsets and edge margins all follow your layout rather than a standard pattern.
Ø0.5 mm is routine; smaller holes are possible depending on thickness — send the drawing for a feasibility check.
Yes, all edges and faces are ground after drilling, so chamfers, steps and grooves can be added without affecting hole positions.
Quality you can verify: Haorui Industrial operates an ISO 9001:2015 certified quality management system (scope: precision mechanical ceramics parts), and our alumina and zirconia ceramics are RoHS 2.0 compliant — tested per IEC 62321 by an accredited third-party laboratory. We exhibit every year at CIOE (China International Optoelectronic Exposition) and semiconductor industry expositions in Shenzhen — visit our booth to see the parts in person.
