PCB Rework

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 to those without the right experience and equipment. We keep an IPC-A-610 certified trainer on staff, and adhere to the IPC-7711/7721 rework standards outlined by the SMT industry.

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 VJ Electronix 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 know that each step we take better serves our clients and their customers.

Reworking PCBs…

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.

  • We analyze manufacturing flaws and find the most cost-effective methods to repair them.
  • 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 salvage expensive and rare components, specializing in BGAs that need to be removed and/or reballed, then install them into new boards or send them back to the customer to be used in their own assembly operations.
  • Eight VJ Electronix rework stations allow our technicians to process a large number of boards in the smallest timeframe, maintaining our exemplary on-time delivery statistics.
  • 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 reball BGAs, removing lead-free alloys and replacing with SnPb or detaching BGAs from existing PCBs then reballing and, if needed, re-installing them into new boards.

And Re-evaluating Design.

Sometimes a project requires the skill of a PCB designer, and we keep one handy. Our friends at Focus Embedded help clients who need to revisit the PCB layout prior to building or reworking a board. They can track down faults, alter the board configuration or even design new PCBs. They work closely with our technicians, helping to plan and define the process that leads to a successful fabrication. If you need help with the design and development of your PCB, visit their site or give them a call at 512.246.9012.

Quick Contact

etech pcb rework 01t

The wire jumper shown here was added to connect two BGA pad sites together, saving the cost of building a new board just to add this connection. Afterwards, we successfully replaced the BGA on top of this rework. Challenges like this are exactly the kind of complex rework we specialize in.

ETECH pcb rework 02t

Three trace modifications are visible on the pad sites of a BGA site. eTech specializes in performing this kind of precise, difficult rework — reworking traces underneath a BGA and properly placing it back on after the changes have been made.

ETECH pcb rework 03t

eTech can locate and resolve issues like the contaminated pads shown here, then restore pad sites, reball the BGA and re-install the component, enhancing signal integrity.
