Semiconductor Board Repair

Probe Station Board Repair

Intermittent motion, I/O or alignment board faults can hold up a wafer prober. GK-SEMI repairs probe station control electronics and helps assess compatible boards when the installed assembly is hard to replace.

Boards We Repair

Illustrative wafer prober motion and I/O control board

We repair serviceable power, interface and feedback circuits on the installed prober board.

  1. 01

    Controller & CPU Boards

    We address board-level supply faults, damaged control components and serviceable connectors while considering original firmware and board revision dependencies.

  2. 02

    I/O & Interface Boards

    Circuit repairs may cover interface drivers, opto-isolators, relays and damaged I/O connectors that interrupt prober communication or interlocks.

  3. 03

    Motion Control Boards

    We review motion-control power and feedback circuits, output stages and board connections involved in stage movement and positioning faults.

  4. 04

    Vision & Alignment I/O

    Repair scope can include interface electronics and signals used by the alignment subsystem; optical system calibration remains a machine-side task.

Why our team

Why Our Team

For your existing prober, component-level PCB work can preserve a known board revision and its installed connections. Our equipment and spare-parts resources also help when the original board is no longer serviceable.

Component-Level Restoration

We repair failed control circuits and connectors on the original prober board, with part number and revision checks before component replacement.

Legacy & Spare-Parts Support

For discontinued ICs and board revisions, we combine repair with parts sourcing to keep compatible options open.

Documented Verification

We document electrical or functional checks on the repaired circuits, separately from machine-side verification.

Original-board repair, mature-equipment parts support, and a clear verification scope—handled in a single enquiry.

For a failed wafer prober board, compare the original hardware revision, interface fit and return checks—not only the replacement price.

Repair Options

For a failed wafer prober board, compare what happens to your installed hardware revision, interface fit and return checks—not just the price of a replacement board.

Original Equipment Manufacturer
OEM Service
Authoritative, but bound by factory policies and lifecycles.

Repair Depth

Board-level replacement. OEM support may favor an assembly exchange, depending on platform age and the available service program.

Legacy Support

Availability and OEM service depend on the board revision and equipment lifecycle.

Data & Config

A substitute board may require firmware, I/O mapping and alignment-system checks.

Lead Time

Lead time depends on board availability and the selected OEM service route.

Independent Electronics Repair
Our Board Repair
A repair route combining work on the original board with relevant replacement sourcing.

Component-Level Diagnostics

We isolate the affected PCB circuit and repair serviceable components or connections before return checks.

Legacy & EOL Rescue

For discontinued revisions, we assess serviceable circuits and investigate compatible parts and board availability.

Original Board Retained

Repairing the original board can avoid replacement revision and configuration changes; programmed devices need appropriate handling.

Fast-Track Response

Discuss fault details and board revision with our online team; assessment timing depends on unit condition and workload.

Standard Third-Party Shop
Local Repair Shop
Cheaper upfront, but with high technical risks and blind spots.

Repair Depth

Confirm whether the shop repairs motion and I/O circuits or only substitutes complete boards.

Legacy Support

Check availability of discontinued components and matching board revisions.

Data & Config

Ask how programmed devices and original configuration data are handled.

Verification

Ask which repaired circuits receive documented electrical or functional checks.

If Repair Is Not Viable: We can also search for a compatible prober board by part number, revision and installed configuration.

Repair Case / Existing Project

200mm

Repair Case

A mature wafer prober developed intermittent axis positioning faults after warm-up. The existing board and installed configuration remained central to the repair work.

Intermittent Axis Feedback Fault REPAIR RECORD SUMMARY
Reported issue

Recurring positioning alarms and a position-readback mismatch after the machine warmed up.

Board work

The repair review focused on the feedback-interface and driver-related channels of the existing board.

Configuration

Hardware revision, connector fit and firmware dependencies were considered for the installed prober.

Verification

Board-level bench functionality was restored and documented in the service record.

Recorded outcome · Bench function restored

The recorded result is board-level bench restoration. Machine-side operation still requires verification after reinstallation.

Before You Send It

Board FAQs

Straight answers to the questions that affect repair approval, configuration and return to service.

Can you repair controller and motion boards from older wafer probers?

We work on controller, I/O, motion and alignment-related electronics used in established wafer prober platforms. Board identification, revision and the failed function determine the repair scope.

What can be repaired on a prober control PCB?

Our board work can include damaged power, interface, driver and signal circuits and associated electronic components. We check the fault path before deciding which components require work.

How is a repaired board checked?

Checks focus on the repaired circuits and accessible board functions. Final axis positioning and prober operation must be verified after the board is reinstalled.

Why repair the installed board instead of buying a replacement?

Keeping the original board can preserve connector fit, revision compatibility and installed configuration while avoiding a difficult search for an obsolete part.

Can you support a discontinued board revision?

We can assess the original assembly and use our parts and equipment resources to investigate repairable components or a matching replacement if necessary.

Will you change firmware or stored prober settings?

Configuration storage is considered before work on memory or control circuits. Any required data intervention is discussed against the board condition and available records.

What should I send to start a board repair inquiry?

Send the prober and board identification, the alarm or failed function, and a clear board photo. We will discuss repair feasibility and the next practical step.
