Fixture and substrate location
Define location, clamping, and changeover around probe type, substrate, and process.
Engineering program ยท specifications require sample and fixture confirmation
MEMS probe card placement and assembly automation.
Build a traceable workstation around fixturing, vision alignment, recipe execution, process records, and post-assembly validation. This public page does not pre-claim accuracy or throughput before sample qualification.
Assembly station and validation station share one data chain.
The objective is not an isolated mechanical move. Assembly results should flow into AOI, XYZ position, height, Pin Force, and electrical validation.
Vision-assisted placement
Alignment, in-process confirmation, and exception marking are frozen with samples and acceptance criteria.
Recipe and traceability
Record work order, material, operator, recipe version, and result before downstream validation.
Current public material does not support a universal probe-placement accuracy, UPH, or production-installation count. Those values must be written into the technical agreement after probe, substrate, fixture, and acceptance method are defined.
Post-assembly verification path
Probing's current validation equipment already connects AOI, XY position, Z height, Pin Force, channel electrical test, one-to-one mapping, reports, and data storage. The assembly program is designed to hand off into that evidence chain.
- VisualAOI status, contamination, missing or abnormal probes
- GeometryXY position, Z height, and contact location
- PhysicalPin Force where the configured module applies
- ElectricalOpen/Short, leakage, contact resistance, and channel mapping
Qualification before specification.
The engineering path keeps sample evidence, fixtures, and acceptance methods ahead of published numbers.
Samples and criteria
Confirm probe type, card type, assembly samples, and judgement standards.
Fixtures and recipes
Design fixtures, motion, interfaces, and safety boundaries.
FAT
Verify function, takt, records, and exception handling on agreed samples.
SAT and traceability
Freeze versions, training, spares, and service after on-site acceptance.
