Enterprise PCB Component Replacement & Repair

Module swapping replaces the entire PCB. Component-level repair identifies the specific failed element, reducing cost and preserving proprietary or discontinued hardware that is no longer available from the OEM.

OHMz utilizes high-magnification microscopy, digital multimeters, and oscilloscopes for power rail and signal integrity testing. Component replacement is performed using precision hot-air rework stations and temperature-controlled soldering irons, with ultrasonic cleaning for flux and contamination removal.

No. Repairability depends on board condition, availability of matching components, the presence of conformal coatings, and the extent of multi-layer internal damage. Each PCB is evaluated for its viable restoration path.

Cost varies by the component type, board complexity, and extent of damage. A simple capacitor replacement is far less expensive than a multi-rail power section rebuild. We provide a no-obligation assessment and quote after diagnosis so you know the exact cost before any work begins.

Simple repairs with common components can be completed in 3-5 business days. Complex multi-fault boards or those requiring rare components may take 7-14 business days. An estimated timeline is provided after initial diagnosis.

Yes. Replacing a single failed regulator or capacitor is significantly more economical than replacing a high-value controller board, especially for industrial or legacy business hardware.

OHMz provides a technical assessment. If a new board is more reliable or cost-effective given the damage, we recommend replacement. If the original board is recoverable, we quote the restoration path.

Component-level repair targets the physical hardware capacitors, MOSFETs, voltage regulators not storage chips. However, if the board contains firmware or configuration data, we take every precaution to preserve it. We always confirm data retention as part of our verification process.

When repaired using matched or upgraded components and proper soldering profiles, a restored board typically matches or exceeds the reliability of the original. Most repaired boards return to full service life, provided the root cause (e.g., overheating, power surge) has also been addressed.

Yes. While OHMz primarily serves business and industrial customers, individual inquiries are welcome. Contact OHMz with your board details we will evaluate the repair and do our best to help regardless of whether the equipment is business or consumer-grade.

Yes. While multi-layer boards complicate trace repair, we perform targeted component replacement and surface-level restoration based on the specific failure mode.

Yes. Printer formatter boards, scanner mainboards, and similar imaging/logic PCBs are common repair candidates. These boards often fail from power surges, capacitor aging, or liquid ingress and are well-suited to component-level restoration.

Yes. Blown or bulging electrolytic capacitors are among the most common failures we see. We replace failed capacitors with equivalent or higher-rated components, then test the surrounding power rails to confirm no other damage was caused by the capacitor failure.

Yes. Shorted power rails, failed voltage regulators, or blown input fuses on the mainboard often cause total power failure. OHMz isolates these faults to the specific failed component.

Often yes. We use a multi-stage ultrasonic cleaning process to remove conductive residues and corrosion, followed by component-level repair of any damaged traces or failed semiconductors.

Yes, provided the PCB substrate remains intact. If the heat has carbonized the board or destroyed internal layers, the board may be rejected as uneconomical.

A burnt smell usually means a component has overheated and failed. The repairability depends on how much of the board was damaged. If the burn is localized to a single component and the PCB laminate underneath is still solid, repair is often straightforward. If the board is charred through multiple layers, it may be beyond recovery. We assess this during diagnosis.

Disconnect power immediately and remove any batteries if possible. Do not attempt to power the device on to "see if it still works" this can turn a cleanable contamination into a short-circuit that destroys components. Place the unit in a dry, ventilated area and contact us for intake as soon as possible.

Ideally, yes. Host equipment allows for full functional verification. If only the board is provided, we perform bench-level power and signal testing where possible.

Intermittent faults are diagnosed through thermal stress testing, flex testing, and extended monitoring to identify failing solder joints or temperature-sensitive components.

Diagnosis is included as part of the overall repair assessment. We provide a quote after evaluating the board. If the board is repairable and you approve the work, the diagnosis cost is absorbed into the repair fee. This ensures transparency you know the full picture before committing to the repair.

If the board is determined to be unrepairable during diagnosis, we contact you with the findings and do not charge a repair fee. You only pay if the board is repaired and returned to working condition.

Timeline varies by complexity. Simple power rail faults are diagnosed quickly, while intermittent or complex signal faults require extended analysis. An estimate is provided after initial intake.

Yes. Every board undergoes functional verification, which may include power-on tests, signal integrity checks, or full testing within the host equipment when available.

If a board is determined to be unrepairable due to internal layer damage or lack of parts, we provide a technical explanation and can assist with donor-unit harvesting or disposal.

Yes. OHMz provides a warranty on the specific components replaced and the associated soldering workmanship. Warranty terms cover the repaired fault area if a different, unrelated component fails later, that is treated as a new diagnosis. Full warranty details are provided with your repair documentation.

Each board is logged by serial number upon intake. You receive updates at key milestones: intake confirmed, diagnosis complete (with quote), repair in progress, and final testing/shipping. For batch repairs, we provide serialized tracking across all units.

Yes. OHMz supports batch repair for B2B customers, providing consolidated intake, grouped diagnosis, and serialized return handling.

Yes. We provide inventory storage for repaired units and spare stock to support phased redeployment.

Yes. We provide OHMz-issued documentation including serial tracking, test results, and notes on the components replaced.

Canada Post and any major courier with tracking and insurance is suitable FedEx, UPS, Purolator, or similar. Use a service that provides a tracking number so you can confirm delivery.

For B2B customers sending larger batches or palletized shipments, we can coordinate freight pickup. Contact our logistics team with volume and location details and we will arrange the most cost-effective collection method for your fleet.

Severe contamination is treated with a multi-stage ultrasonic cleaning process to remove conductive residues before diagnosis begins.

Internal shorts are evaluated via signal tracing. If the damage is localized and accessible, restoration is attempted; otherwise, the board is rejected as uneconomical.

Unrepairable boards are documented with a technical explanation of the failure. You can choose to have the board returned to you, retained for donor-component harvesting, or responsibly disposed of. We never scrap a board without your explicit instruction.

Yes. If a board is rejected during diagnosis, we contact you before taking any further action. You can request its return at your shipping cost, or authorize us to retain or dispose of it.
