Finetech 4.0 Ltd., Co: Providing Comprehensive Electronic Component Rework Services (返工/重工不良品）

What is electronic component rework (返工/重工不良品）?

Electronic component rework is the analysis and repair of non-functional printed circuit boards (PCBs). While some products fail due to excessive use and wear over time, others fail due to a failed connection or broken component. Finetech 4.0 Ltd., Co offers a rework service where PCBs can be returned, analyzed, and repaired.

Thanks to our approach towards procurement and warehousing, we always have essential components on hand, allowing us to carry out any repair quickly and efficiently, with minimal costs incurred. This procurement process takes place during the initial design and manufacture process, ensuring that every client can utilize our rework services (返工/重工不良品）should the need arise.

How does Finetech 4.0 Ltd., Co rework (返工/重工不良品）electronic components?

Upon receiving the faulty part, our technicians will first assess the potential fault using state-of-the-art technological equipment. If the fault can be repaired, our technicians will do so. This may involve rerouting the electrical connection to the circuit using new bonding.

If it becomes necessary to replace certain parts of the PCB, our engineers will detach and replace them, with any remaining solder removed from the pads post-removal. After a new component is attached, it will be placed per exact specifications, and the solder will be reflowed.

Our talented technicians can identify and repair PCBs using state-of-the-art equipment, such as our Automated Optical Inspection (AOI) and X-ray Inspection machines, which can identify faults without the need for extensive and time-consuming analysis. An AOI machine performs a visual inspection of each PCB needing repair, immediately identifying any physical defect with the board. This process ensures accuracy and efficiency during the identification of faults.

If you choose to use our rework service, every board we receive is serialized and tracked by our in-house custom Enterprise Resource Planning (ERP) system. Its serial number is kept on record, along with information about its manufacture and whether it was previously processed by our reworking department. This further reduces both the cost and timescale for our repair service since previous information about a fault can often lead to a faster diagnostic check.

After a PCB has been reworked, it will be returned with a problem report documenting the cause of the fault and what has been done to bring it back to working condition. This is so that our clients can understand both what caused the error on their PCB and what Finetech 4.0 Ltd., Co has done. This transparency underlines the efficacy and value that our repair service provides to our clients.

Finetech 4.0 Ltd., Co offers innovative solutions for nearly every kind of electronic rework, including the latest advanced packages (BGA, QFP, CSP, 0201, etc.). As a rule, we can rework any PCB that we originally manufactured, and our specifications can be found on our Literature Downloads page.

In conclusion, at Finetech 4.0 Ltd., Co, we strive to provide a comprehensive range of services to our clients. Our electronic component rework service (返工/重工不良品）is just one example of our commitment to helping our clients stay ahead of the competition and embrace the future of technology.

With our experience in implementing projects, we are confident to satisfy all customers.
