A Flexible Circuit Board (FPCB), commonly referred to as a soft board, is an abbreviation for Flex-PCB and is sometimes called FPC. FPCs and PCBs (Printed Circuit Boards) are similar in function and structure, but PCBs … Read more
PCB Network News Printed Circuit Boards (PCBs), also known as printed wiring boards, printed circuit boards, or printed wiring boards, are defined as conductive patterns made on an insulating substrate according to a predetermined design, which includes printed circuits, printed components, or a combination of both. The conductive patterns that provide electrical connections between components … Read more
There are two types of engineers in the PCB industry. One type of designer possesses specialized knowledge and adheres to strict design standards. Their network wiring, surface mount components, and text are well-organized, with reasonable layout in functional areas that facilitate production optimization. They communicate smoothly, are open to suggestions, work efficiently, and handle their … Read more
1.1 Basic Recognition Mnemonics A circuit board can change in countless ways; the combination of components is key. Resistors and capacitors are the most common; understanding their symbols is essential. Resistance changes and capacitor leakage; remember the basic characteristics. Inductance and voltage changes can be checked; measure the PN junction of transistors. MOSFETs can be … Read more
Many people have experienced making mistakes in PCB packaging—either making it too large or too small, or even having components obstructed, which leads to issues when soldering components after the PCB is manufactured, sometimes requiring manual wire connections; in severe cases, it may even result in the entire board being scrapped. For example, the U8 … Read more

Introduction Resistors are one of the most fundamental components used in printed circuit boards (PCBs). They are passive devices that impede the flow of current in a circuit. PCB resistors can control, divide, stabilize, and connect circuits, among other functions. They come in various resistance values, sizes, power ratings, and tolerances to meet different circuit … Read more
