What is PCB Assembly? PCB Assembly, short for Printed Circuit Board Assembly, is the process of attaching electronic components to a printed circuit board to create a functional electronic device. The process involves several steps, including placing components on the board, soldering them in place, and testing the finished assembly […]

What is PCB Tenting? PCB tenting, also known as via tenting or tented vias, is a process used in the manufacturing of printed circuit boards (PCBs) where the drilled holes (vias) on the board are covered with a thin layer of solder mask material. This technique is used to protect […]

What are Edge Connectors? Edge connectors are a type of electrical connector that is designed to mate with the edge of a PCB. They consist of a plastic housing with a slot that accommodates the PCB, and a series of conductive contact fingers that press against the exposed copper traces […]

What is the MPSA18 Transistor? The MPSA18 is a general-purpose NPN bipolar junction transistor (BJT) designed for low-power applications. It is part of the MPSA series transistors, which are known for their reliability and versatility. The MPSA18 is housed in a TO-92 package, making it easy to integrate into different […]

Introduction to Supercapacitor Charging Supercapacitors, also known as ultracapacitors or double-layer capacitors, are high-capacity electrochemical capacitors with capacitance values much higher than other capacitors. They store 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and […]

What are High-Current Zener Diodes? High-Current Zener Diodes are semiconductor devices that provide a stable reference voltage and offer protection against overvoltage conditions. They are similar to standard Zener diodes but are designed to handle higher current levels. When the voltage across the diode exceeds its specified Zener voltage, the […]

Introduction to LCD interfaces Liquid Crystal Displays (LCDs) are an essential component in many electronic devices, from smartphones and laptops to industrial equipment and automotive dashboards. To effectively use an LCD, it is crucial to understand the various LCD interfaces available and their characteristics. This comprehensive guide will explore the […]

What is a Transistor Switch? A transistor switch is a configuration in which a transistor is used to control the flow of electric current in a circuit, essentially acting as an on/off switch. When a transistor is used as a switch, it operates in either the fully on (saturated) or […]

Understanding Transistors and Their Switching Capabilities Transistors are one of the most fundamental components in modern electronics. These semiconductor devices have the ability to amplify or switch electronic signals, making them essential in a wide range of applications. In this comprehensive guide, we will focus on using transistors as switches, […]

What is Flying Probe Test? Flying probe test is an advanced method for testing printed circuit board assemblies (PCBAs) that uses moving test probes to make contact with test points on the board. Unlike traditional bed-of-nails in-circuit test (ICT) fixtures which have fixed probes and require a custom test fixture […]
