MEMS Probe Card Pin Assembly and Laser Micro-Welding
The station is configured around the probe, substrate, fixture and datum. Each probe passes three gripper handovers - pick, alignment and weld - before laser micro-welding, and an autofocus check confirms position afterwards. What actually decides yield is not the weld itself but whether a defect can be caught immediately after: that step is handled by PCT5801 electrical test and DeepTouch1000 whole-card touchdown validation.
Category visual for probe card assembly equipment. The actual pick, alignment and laser micro-welding stations are designed per probe type, card type and sample.

04 Verify
The same points in words
- Pick
- The pick gripper takes the probe from the tray and seats it against the alignment datum Avoiding added distortion during handover is the precondition for accuracy
- Align
- The alignment stage clamps and corrects probe attitude Gripper coplanarity and perpendicularity are the critical assembly metrics
- Weld
- The weld gripper transfers the probe and laser micro-welding runs Joint consistency controlled by vision and recipe
- Verify
- Autofocus position check, then PCT5801 and DeepTouch1000 Locates weld problems while still at the assembly stage

The same points in words
- Sample evaluation
- Confirm the object, interfaces, current state, failure modes and available validation samples.
- Technical agreement
- Define configuration, measurement method, limits, takt, data interfaces and responsibilities.
- FAT
- Verify functions, repeatability, reporting and exception handling with agreed samples.
- SAT
- Complete site integration, training, upstream/downstream interfaces and issue closure.
CONFIGURATION
Configuration and acceptance
System configuration, optional items and acceptance conditions are summarized below.
Process parameters
Placement accuracy and UPH are determined by sample trials on the target probe, substrate and fixture; no universal cross-customer figure is published.
Closed-loop capability
PCT5801 covers post-weld electrical verification and DeepTouch1000 covers whole-card touchdown and 3D tip inspection, so anomalies trace back to a specific probe position.
Deliverables
Fixtures, algorithms, takt and the post-inspection combination are written into the technical agreement and verified at FAT/SAT.
