Introduction to PCB Panels Printed Circuit Boards (PCBs) are the backbone of modern electronics. They provide a reliable and efficient means of connecting electronic components in a compact and organized manner. PCBs are used in a wide range of applications, from consumer electronics to industrial equipment and aerospace systems. In […]

PCB Essentials: Understanding the Basics of 4 Layer PCBs Introduction to 4 Layer PCBs A 4 layer PCB, or printed circuit board, is a complex electronic component that consists of four conductive layers laminated together with insulating material. These boards are widely used in various applications, from consumer electronics to […]

Introduction to PCB Stackup Printed Circuit Board (PCB) stackup refers to the arrangement of copper and insulating layers that make up a PCB. The stackup design is crucial in determining the electrical properties, signal integrity, and overall performance of the PCB. In this article, we will delve into the world […]

What is PCB Stackup? PCB stackup refers to the arrangement of layers in a multi-layer printed circuit board. It involves stacking alternating layers of conductive copper and insulating materials, such as FR-4, to create a compact and efficient circuit board. The number of layers in a PCB stackup can vary […]

What is a DIAC? A DIAC, or Diode for Alternating Current, is a two-terminal, Bidirectional Switching device that conducts current only after its breakover voltage has been reached momentarily. Once this threshold is reached, the DIAC continues to conduct until the current falls below the holding current. DIACs are widely […]

What is a DC Chopper? A DC chopper is a power electronic device that converts fixed DC input voltage to a variable DC output voltage. It is essentially a high-speed switch that rapidly connects and disconnects the load from the power source, effectively “chopping” the DC voltage into discrete pulses. […]

Introduction to Opto-Isolator Circuits An opto-isolator, also known as an optocoupler or optical isolator, is an electronic component that provides electrical isolation between two circuits using light. It consists of an LED (light-emitting diode) and a photosensitive device, such as a phototransistor or photodiode, encased in a single package. The […]

Understanding DC Motor Speed Control To effectively control the speed of a DC motor, it is important to understand the fundamental principles behind its operation. A DC motor consists of a stator (stationary part) and a rotor (rotating part). When a DC voltage is applied to the motor, current flows […]

What are Halogen-free PCBs? Halogen-free PCBs are printed circuit boards that do not contain any halogenated flame retardants (HFRs) or other halogenated materials. Common halogens used in PCBs include chlorine (Cl) and bromine (Br). These substances can be harmful to the environment and human health when released during PCB manufacturing, […]

Introduction to Bidirectional Switches A bidirectional switch, also known as a bilateral switch or a double throw switch, is an electrical component that allows current to flow in both directions through a circuit. Unlike a regular switch that only allows current to flow in one direction, a bidirectional switch enables […]
