Different Types Of PCB Repair

A printed circuit board or PCB is a core component of nearly all electronic devices. Everything except the simplest of electronics uses a board of some kind to connect and mechanically sync all elements of the product. A coffee maker, for instance, might have a small PCB inside to connect the electronic control system, heater element and display.

In the early days—way before design software was a thing—printed circuit boards were planned using Mylar sheets through manual hands-on development, and were often four times bigger than the circuit board itself. The designers would lay pin pads, traces and components out in a proposed design, which was used sort-of like a storyboard to test and explain circuits. Today, it’s all done via design and manufacturing software.

Electronic PCB repair is mechanically necessary to support and connect all components within the device, which are synced using conductive tracks—this allows electricity to flow freely through the board and from component to component. PCB components are soldered to the board, which electrically and mechanically fastens them to the overall circuit. Those “components” include things like the battery, resistors, LEDs, transistors, capacitors and more.

Boards are often produced in layers, which include panel view repair levels of conductive and non-conductive sheets. They can be one-sided with a single copper layer, two-sided with a double copper layer on both sides of a substrate layer, or multi-layer with differing layers of copper and substrate. It is worth mentioning that multi-layer boards provide a variety of benefits like an increased component density, however they are much harder to analyze, repair and modify.
