Rework/Repair

Rework

From fine pitch components (tolerances as low as .4 mm) to complex mixed-pitch patterns, we provide a level of precision rarely matched in the industry. No matter what stage of development you’re in, we can get your project to the next phase.

As more elaborate components have populated more complex PCBs, we’ve enhanced our services, added new capabilities, educated our staff and upgraded our tools. We’re constantly improving to meet the needs of our customers, their devices and their markets; to provide each of our clients with a path from concept to completion.

We specialize in complex projects involving package-on-package, LGA, QFN, CSP and other components that present real challenges and we keep an IPC-A-610 certified trainer on staff, and adhere to the IPC-7711/7721 rework standards defined by the IPC.

We insist on working with the best tools and the right methods, like employing compressed nitrogen to reduce oxidation during rework performed on one of our nine rework stations. This critical advantage is especially important for rework performed on fine-pitch components, prototypes, expensive or irreplacable PCBs, or devices that demand reliability.

We develop clearly defined and repeatable processes to make rework as dependable as the original manufacture and to make it easier to perform the same operations on any future projects.

During and after rework, we inspect what we’ve done using tools like the Vertex 130KV X-Ray Inspection System and the Technolab BGA Inspector Endoscope, completing a 4-point inspection on each component we place. For some projects, we can also perform 5D X-ray, used to locate and address the most difficult manufacturing and reworking issues.

We modify complex prototypes to improve or alter a board’s function, giving developers a chance to determine if their modifications are working before moving to the next stage of prototype development or manufacturing.

Repair

We make repairs that few in the industry are willing to attempt. We’ll perform trace modification in the most inaccessible areas, including under BGAs or other sensitive components.

We repair defective boards and prototypes, correcting manufacturing faults of all kinds: damaged traces and solder mask, incorrectly installed components, manufacturing defects — whatever electrical or mechanical flaws keep your PCB from functioning optimally. In a single manufacturing run, several different boards may present several different types of faults; we’ll analyze each mechanical problem, propose appropriate solutions and repair each one the right way. 

We repair and restore pad sites for any component, including fine-pitch and variable-pitch BGAs, QFNs, and package-on-package stacks. Corfin technicians routinely rework the most intricate PCB designs, saving even heavily damaged boards.

Multiple rework stations allow our technicians to process a large number of boards in the smallest timeframe, maintaining our exemplary on-time delivery statistics.

We analyze manufacturing flaws and find the most cost-effective methods to repair them.
