Probe Card Repair Services | Extend the Life of Your Probe Card

1. Introduction to Probe Card Repair

In the semiconductor industry, the probe card plays a pivotal role during wafer-level testing, serving as the interface between the tester and the integrated circuits (ICs) on the wafer. As the first point of physical contact, the probe card must maintain high precision and mechanical integrity to ensure accurate signal transmission and yield assurance.

Over time, due to repetitive mechanical contact and thermal cycling, probe cards experience wear and degradation. This can result in poor contact, signal loss, or even wafer damage. A carefully executed probe card repair process restores the card’s functionality, extending its lifecycle and preserving test performance without the need for full replacement.

2. Common Issues That Require Probe Card Repair

Probe card damage is inevitable in high-volume semiconductor testing environments. Prompt and precise repair is crucial to avoid yield loss or inaccurate test data. Below are some of the most frequent issues encountered:

Typical Problems:

In cases where one or more needles are below repair threshold or show signs of burning, it is sometimes necessary to reset the probe array—a process that requires disassembling and reattaching probes with precise spacing.

3. Our Probe Card Repair Process

At JUNR Semiconductor, we follow a systematic and data-driven approach to probe card repair. Our repair services aim not only to restore functionality but also to ensure consistent electrical performance post-repair. The process is as follows:

Step-by-Step Repair Workflow:

1. 3.1 Visual & Functional Inspection

   • Initial check of probe card condition using microscopes and test equipment.

   • Identification of damaged, bent, or missing probes.

2. 3.2 Evaluation of Repair Feasibility

   • Measurement of current needle heights and comparison to original specs.

   • Analysis of burn marks or severe probe deformation.

   • Determination of whether re-tipping, realignment, or full reconfiguration is necessary.

3. 3.3 Customer Consultation (if applicable)

   • If any needles fall below the minimum repair length or have sustained burn damage, we contact the client to discuss rework options.

   • For board reset cases, written customer confirmation is required before proceeding.

4. 3.4 Precision Repair Execution

   • Mechanical adjustment of tip height and planarity.

   • Re-polishing or replacement of probe tips as needed.

   • Special handling for multi-site step calibration.

5. 3.5 Cleaning & Surface Preparation

   • Removal of contaminants from the probe surface to ensure optimal electrical contact.

6. 3.6 Final Testing & Quality Check

   • Electrical continuity and resistance tests to confirm functionality.

   • Optical inspection to verify geometric alignment.

4. Information Required from Clients for Repair

To perform accurate and effective probe card repair, it is essential for clients to provide detailed technical data about the card. This ensures the repaired probe card aligns perfectly with the original wafer layout and test parameters.

Required Client Data:

• Pad Coordinates:

  • A detailed pad layout file (usually in .txt or CAD format) containing the X-Y coordinates of the probing points.

• Original Probe Tip Dimensions:

  • Probe mark size and initial needle length to evaluate wear levels and maintain uniformity during repair.

• Multi-site Configuration:

  • For multi-DUT (device-under-test) probe cards, clients must provide step sizes that include the distance across each site and scribe lane dimensions.

• Damage Declaration:

• If probe burning or breakage has been observed, the extent should be reported for evaluation.

• If the tips are shorter than the repairable standard, a reset option will be suggested.

5. Repair Report and Quality Control

At JUNR, we believe that a transparent and data-driven approach to probe card repair is critical to earning our clients’ trust. That’s why every repaired probe card is accompanied by a comprehensive repair report that outlines the work performed and the quantitative results before and after servicing.

What’s Included in Our Repair Report:

Every report is reviewed internally by a senior technician before release. If any inconsistencies remain post-repair, the card will be reworked immediately at no additional cost.

Strict Quality Assurance Protocols:

• Calibrated inspection and measurement tools

• Dual-check validation (optical + electrical)

• ISO-compliant process control documentation

• 100% functional testing before return shipment

We understand that probe card reliability directly impacts wafer yield. That’s why quality is never compromised in our facility.
