In electronics, rework (or re-work) is the repair or refinish of a printed circuit board (PCB) assembly, usually involving desoldering and re- soldering of surface-mounted electronic components (SMD). Mass processing techniques are not applicable to single device repair or replacement, and specialized manual techniques by expert personnel using ...
A via (Latin, 'path' or 'way') is an electrical connection between two or more metal layers of a printed circuit boards (PCB) or integrated circuit. Essentially a via is a small drilled hole that goes through two or more adjacent layers; the hole is plated with metal (often copper) that forms an electrical connection through the insulating ...
Printed circuit board of a DVD player. Part of a 1984 Sinclair ZX Spectrum computer board, a printed circuit board, showing the conductive traces, the through-hole paths to the other surface, and some electronic components mounted using through-hole mounting. A printed circuit board ( PCB ), also called printed wiring board ( PWB ), is a medium ...
Conformal coating is a protective, breathable coating of thin polymeric film applied to printed circuit boards (PCBs). Conformal coatings are typically applied at 25–250 μm [ 1] thick to the electronic circuitry to protect against moisture and other potentially damaging conditions. Coatings can be applied in many ways including brushing ...
Electronic components have a wide range of failure modes. These can be classified in various ways, such as by time or cause. Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical shock, stress or impact, and many other causes. In semiconductor devices, problems in the device package may cause ...
Reverse engineering of Printed circuit boards (sometimes called “cloning”, or PCB RE) is the process of generating fabrication and design data for an existing circuit board, either closely or exactly replicating its functionality. Obtaining circuit board design data is not by necessity malicious or aimed at intellectual property theft. The ...
A motherboard (also called mainboard, main circuit board, MB, base board, system board, or, in Apple computers, logic board) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central ...
Troubleshooting. Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
