Circuit Board Repair

Found in almost all electronics, printed circuit boards (PCBs) provide the basic technology that enables mobile devices, computers, and other electronics to function. They are generally built with layers of copper and non-conductive insulation material and provide a compact way to keep components safely insulated while connected to a power source. 

Circuit boards are becoming increasingly space-efficient and affordable, but it is vitally important to select the appropriate PCB for a given application to ensure that components remain safe and functional.

Different Types of Circuit Boards

Circuit boards come in a variety of designs, each appropriate for specific use cases. Some of the main designs include:

  • Single-sided. Best used in simple electronics, single-sided circuit boards have just one layer of base material coated in a layer of conductive metal. All of the circuits are located on one side.
  • Double-sided. One of the most commonly used types of PCB, double-sided circuit boards features circuits and conductive layers on both sides. 
  • Multilayer. Multilayer circuit boards are thicker than double- or single-sided boards. Their many layers provide extra power supply to the circuits and reduce electromagnetic interference.
  • Rigid. Frequently made out of materials like fiberglass, rigid circuit boards are inflexible and often found inside computer towers.
  • Flex. Flex circuit boards are made from flexible plastic, enabling them to fit into a wider variety of forms, including complex machinery such as satellites. These boards can twist without disrupting the circuits.
  • Rigid-flex. Rigid-flex circuit boards consist of a flex board joined to a rigid board. They can be customized to fit the needs of their intended application.

Known Circuit Board Issues

Due to their ubiquity, circuit board failures can cause huge problems. PCB failure often leads the entire electrical device to shut down. Circuit boards can encounter a number of common problems, such as:

  • They can be physically damaged if the device containing them is dropped or roughly handled.
  • Faulty components are also common—older boards are more likely to encounter component failures, as are boards that have been frequently overheated.
  • Environmental factors often lead to boards expanding and contracting, as well as corroding due to excessive moisture exposure.  

Circuit boards may encounter additional issues if not properly designed. For example, if there is not enough clearance between the copper and the edge of the circuit board, the copper may be exposed during trimming. This can lead to corrosion, shortening the lifespan of the board. Finding the right experts to repair circuit boards is vital to ensuring their longevity.

Can a Circuit Board Be Repaired?

While there are a wide variety of issues that circuit boards may encounter, it is often possible to fully repair the circuit board rather than simply replacing it. For over 40 years, our experts at Schneider Electric have been setting the standard for repairing industrial electronics. We offer a wide array of services, including scheduled maintenance programs, integrated manufacturing support services, and repairs and upgrades of our automation products. 

If a circuit board has become obsolete, we will design and fabricate replacement components that may otherwise be difficult to find. This option is often more affordable than replacing the entire board. 

Throughout everything we do, we are committed to providing innovative solutions and exceptional customer service that our customers can rely on.
