Introduction Creating an electronic circuit project typically involves the production of a Printed Circuit Board (PCB). Many different types of PCBs are available on the market today. However, single-layer PCBs hold a distinct position among the various types of printed circuit boards. If you are wondering what a single-layer PCB Read more
Introduction A blank PCB, often referred to as a bare board or printed circuit board, is an insulating substrate with pre-etched conductive copper traces (circuitry) and drilled holes for mounting electronic components. However, it has not yet been populated with any electronic components (such as resistors, capacitors, chips, etc.). Think Read more
Introduction Printed Circuit Board Assembly (PCBA) involves assembling various electronic components onto a Printed Circuit Board (PCB) to create a functional electronic device. This process is crucial in electronics manufacturing. It transforms a bare PCB, lacking components, into a fully functional unit. The PCBA serves as the core of many Read more
Circuit symbols play a crucial role in electrical and electronic diagrams, representing complex circuits and components in a standardized and simplified manner. These symbols are vital for engineers, electricians, and technicians to understand circuit functionality, often without referring to extensive documentation. Their universal recognition ensures consistent interpretation across different languages Read more
A single-layer PCB, also known as a single-sided PCB, is a specific type of printed circuit board. Its characteristic is that only one side of the board has a single layer of conductive material, while the other side is used for integrating various electronic components onto the board (the conductor Read more
Introduction Light Emitting Diodes, commonly known as LEDs, are an increasingly popular lighting technology across various industries. LEDs are a form of solid-state lighting that uses semiconductors to convert electrical energy into light energy. Compared to traditional bulbs, LEDs can save up to 80% in energy consumption and last up Read more
PCBs often require screw holes for fastening; for instance, adding special holes like countersinks and counterbores to the board allows them to be secured in place using different types of screws. Many PCBs require some form of mounting hardware, hence many PCB designs include non-plated mounting holes. Some customers have Read more
Introduction Printed Circuit Board (PCB) design has evolved into a distinct specialty within the electronics industry. PCBs play a vital role by providing electrical interconnections between components, rigid support for mounting those components, and a compact package that can be integrated into the final product. They are the primary components Read more
The image above shows a real varistor. You might mistake them for capacitors. However, varistors and capacitors don’t have much in common besides their size and design. Varistors are used to suppress voltage surges, a function capacitors cannot perform. A varistor is a resistor whose resistance changes with the voltage Read more
Introduction If you work in the printed circuit board (PCB) industry or simply use electronic devices, you know that post-production testing is crucial before any device reaches the market. Functional Circuit Test (FCT) is a key step in the PCB Assembly (PCBA) quality control process and a fundamental skill that Read more
