An electrical schematic, or simply 鈥渟chematic鈥�, is a diagram that uses symbols to accurately represent the components and interconnections within an electrical or electronic circuit. Being able to read and understand schematics is an essential skill for anyone working with electronics as an electrician, circuit designer, technician, engineer and even hobbyist. This article provides a […]
Read articleThe electronic manufacturing services (EMS) industry refers to companies that design, test, manufacture, distribute and provide return/repair services for electronic components and assemblies for original equipment manufacturers (OEMs). The EMS market has seen substantial growth over the past decade, driven by factors like: This article provides an in-depth analysis of the size, growth trends and […]
Read articleEpoxy refers to a class of high performance thermoset polymers valued for mechanical strength, temperature resilience, and electrical insulation. Such attributes make epoxies ideal protecting printed circuit boards (PCBs) which serve as the backbone of electronics. Epoxy coatings shield delicate PCB components and traces from environmental stresses that could otherwise impede functionality or shorten product […]
Read articleIntroduction to ESD Trays ESD stands for “electrostatic discharge”. This refers to the sudden flow of electricity between two electrically charged objects. In the electronics industry, ESD can be extremely damaging to sensitive components such as integrated circuits, semiconductors, and printed circuit boards. An discharge as small as 30V can brick delicate electronics. ESD trays […]
Read articleBefore diving into the specifics of the first circuit board ever made, it’s helpful to understand the history leading up to their invention. Circuit boards are the foundation of most modern electronics. They allow components like integrated circuits, resistors, capacitors, and more to be interconnected in a structured way. This enables signals to pass between […]

Reducing thickness changes handling, stiffness, flatness and assembly support, but it does not automatically turn a glass-epoxy board into a circuit intended for repeated dynamic bending. The exact…
Read articleA fuse holder is a small device designed to hold a fuse and connect it safely to a printed circuit board (PCB). Fuses are important safety components in electrical circuits as they protect the circuit and connected components from overcurrent. The key things to know about fuse holders in PCB circuits are: Terminology What They […]
Read articleGerber files are the standard format used to transfer PCB design data to fabrication and assembly companies. Gerber viewers allow engineers and designers to visualize these files during the design review process. They translate the abstract Gerber data into more intuitive images showing traces, pads, drill holes, copper fills, and other key features. Choosing the […]
Read articleA PCB (Printed Circuit Board) is an integral component of all computer graphics cards, including GPUs (Graphics Processing Units). The PCB serves several key functions: Mounting Components The PCB provides a surface to mount and connect critical GPU components like: Facilitating Communication The traces etched into the PCB facilitate communication between mounted components. This allows […]
