PCB Rework Services

A defective component, solder joint issue, or engineering change does not always require scrapping an otherwise usable PCB assembly. Blind Buried Circuits provides PCB rework services for SMT and through-hole assemblies, including component removal and replacement, localized solder rework, mini-stencil applications, and selective soldering.

Before rework begins, we evaluate the affected area, component requirements, board condition, and rework scope to determine an appropriate process while minimizing unnecessary thermal and mechanical stress on the assembly.

What Causes PCB Rework?

PCB rework is often required when an assembled circuit board does not meet the required functional or assembly condition. The issue may involve a component, solder connection, or another part of the assembly.

Common reasons for circuit board rework include:

A component has become shorted or is no longer functioning.
A defective or unusable component needs to be replaced.
An incorrect component needs to be removed and replaced with the specified component.
A component is suspected to be counterfeit or does not meet the required specification.
Soldering or component placement issues need to be corrected.
An existing PCB assembly requires a component change without replacing the complete board.
Through-hole components require additional soldering or replacement.

Before beginning PCB rework, you can provide your board, component, and project information so we can understand the required work and determine the appropriate rework method.

PCB Rework Services Offered by Blind Buried Circuits

You can use our PCB rework capabilities to address specific component and assembly requirements, including high volume electronics rework services, without unnecessarily replacing the complete PCB.

Component Replacement: If a component is shorted, non-functional, defective, or otherwise unsuitable, we can remove the affected component and replace it with the required component. This allows you to correct a specific assembly issue while retaining the existing PCB.
SMT PCB Rework: Our (surface mount technology) SMT rework service supports correction and replacement of surface-mount components. We can address the affected component or area based on your PCB assembly requirements and the condition of the board.
Mini Stencil Rework: For component-level rework, we can create and use a mini stencil to apply solder paste to the required area. This provides a practical approach when a specific component needs to be replaced without processing the entire board through the original assembly process.
Through-Hole Rework: We also support rework of through-hole components. Where required, selective soldering can be used to solder through-hole PCB components while limiting the process to the required areas of the PCB assembly.
PCB Assembly Rework: If your assembled board requires component replacement, soldering correction, or other assembly-level changes, our PCB assembly rework services can help you address the specific issue rather than replacing the complete assembly.

Rework for Your Production Requirements

Your rework requirements can vary depending on the number of boards, component type, assembly condition, and required turnaround. We can review your printed circuit board rework requirements and determine the appropriate approach for the work involved.

Our electronics rework services can support individual board requirements as well as projects requiring repeatable rework processes. There is no minimum order quantity (MOQ) for our PCB rework services, allowing you to request rework based on your actual project needs.

For larger production requirements, discuss your board quantity, component requirements, and rework scope with our team so we can evaluate the appropriate process for your project.

Benefits of Professional PCB Rework

Professional PCB rework can help you correct specific assembly issues while keeping the existing board in service. Depending on the condition of your PCB and the required modification, rework can provide several practical benefits:

Avoid Complete PCB Replacement: You can replace or correct an affected component without discarding the entire PCB assembly when the rest of the board remains usable.
Restore Component Function: Rework can address shorted, failed, defective, or non-functional components through appropriate removal and replacement.
Correct Assembly Issues: You can address soldering, component placement, and other localized assembly issues without rebuilding the complete board.
Preserve Existing PCB Designs: Rework allows you to retain an existing PCB design when only specific components or assembly areas require changes.
Reduce Production Disruptions: Correcting an identified assembly issue can help you continue using affected boards instead of waiting for complete replacement assemblies.
Support Engineering Changes: Component replacement and localized rework can help accommodate required changes to an existing PCB assembly without redesigning the entire board.

Why Choose Blind Buried Circuits for PCB Rework?

When you need to rework an existing PCB assembly, choosing the right rework partner can help you correct the identified issue while protecting the rest of the board. At Blind Buried Circuits, we review your board condition, component requirements, and rework scope to determine a practical approach for your assembly.

With our PCB rework services, you can work with a team experienced in SMT and through-hole rework, component replacement, mini-stencil applications, and selective soldering. We focus on localized rework where appropriate, helping you avoid unnecessary replacement of an otherwise usable PCB assembly. Our team also considers surrounding components, solder connections, and board integrity during the rework process.

You can share your board details, component information, quantity, and specific rework requirements with our team so we can evaluate the project and determine the appropriate PCB assembly rework approach for your application.

Frequently Asked Questions

What are PCB rework services?

PCB rework services involve modifying an existing PCB assembly to correct a specific component or assembly issue. This may include removing and replacing components, correcting solder-related issues, or reworking SMT and through-hole components without replacing the complete PCB assembly.

Can you replace a component that is shorted or no longer working?

Yes. If a component on your PCB assembly is shorted, non-functional, defective, or otherwise unusable, we can evaluate the affected area and replace the component when the board and rework requirements are suitable.

What can cause a PCB assembly to require rework?

A PCB assembly may require rework when a component becomes shorted or stops functioning, a defective or unsuitable component needs to be replaced, an incorrect component has been installed, or an SMT or through-hole assembly issue needs correction.

Can you rework both SMT and through-hole components?

Yes. We provide SMT rework and through-hole rework based on the requirements of your PCB assembly. Through-hole rework can also involve selective soldering for the required components or areas.

Can you use a mini stencil for component replacement?

Yes. We can create a mini stencil for localized solder paste application when required for component-level rework. This can be useful when you need to replace or rework a specific component on an existing PCB assembly.

Do you have a minimum order quantity for PCB rework?

No. We do not require a minimum order quantity for our PCB rework services. You can discuss your board quantity and specific rework requirements with our team.
