When Circuits Fail, PCB Board Repair Rescues Them

Posted by Laura Austin on Tue, Feb 26, 2013 @ 07:00 AM

No matter how good electronic contract manufacturers become at producing ever-smaller and more complex circuit boards, every now and then, a defect  will be produced. Sometimes, if it's
PCB-boardpart of a large production run, this isn't a major issue: a certain (small) percentage of lossage is expected. However, what if your circuit board is unique, such as for a prototype or a specific custom purpose?

If that board fails, you could be looking at huge costs to recreate it, or even larger costs if you move forward anyway.

In these cases, there's only one other option: utilizing a PCB board repair service. Along with manufacturing, many electronics production services also include repair and rework services which can be utilized to save an investment from being a failure.

How can PCB board repair save you money in a crisis? There are three major ways it can be utilized: Repair, Rework, and Modification.

PCB Board Repair Scenarios

  1. Repair

    This is the most common reason you might need to utilize such services: a part which was working has failed, and you don't know why. Luckily, electronics experts can analyze both the original schematics and the resulting board to discover the underlying problem. Often, it's something as simple as a single broken bit of circuit wiring or a single failed component that can be fixed for far less than it would cost to recreate the board.

  2. Rework

    Sometimes, it's the initial design that's flawed. A capacitor cannot handle the charge it needs, or a particular computer chip proves to be incompatible with the board. In this case, PCB board repair services can take a look at the original design specs, compare them to the finished product, and uncover which component(s) are causing the issue.
    From there, it's a relatively simple matter to find suitable replacements which can meet your original specifications.

  3. Modification

    Or, perhaps your PCB works, but just not quite up to par. Perhaps it fails to meet a necessary requirement, such as FCC feedback shielding standards. If this is the problem, much as with rework efforts, your PCB repair service can take the working design and improve on it so it meets your needs.

What To Look For In PCB Board Repair Services

When you're looking for a repair service, there are a few important matters to consider.

  • Standards and Certifications. There are numerous global standards agencies, such as the IPC Association, that maintain industry-specific standards for electronics work. Of these, the IPC-7711 / 7721 standard is the most important, relating directly to electronics repair and rework. While certification is not a guaranteeof quality work, it can give you a lot of assurance when you deal with a company that's certified in your area of need.

  • Supply chain expertise. A repair service that cannot guarantee quality componentsPCB-board-repair won't be able to guarantee their repairs will hold. Pick a firm which specializes in supply chain management, so you can know your PCB will be repaired using nothing but genuine components and materials.

  • Testimonials and case studies. The proof is in the pudding, as they say. If you're in doubt about a repair service, ask them for referrals or case studies demonstrating their expertise. After all, there's no surer sign of good work than a happy customer.

If you have a mission-critical PCB that isn't working as it should, don't toss it out and incur huge losses in trying to replace it. Simply hire a PCB board repair service to make the necessary adjustments at a much lower price.
