Electrostatic discharge (ESD) occurs when any charged body attempts to become electrically neutral. During ESD, the static charges stored in one body rapidly get transferred to another at different electrical potentials through direct physical contact, induction, or arcing. ESD generates voltage that can damage electronic components. Electronic parts that are sensitive to ESD voltage are
This article will summarize the differences between the integrated circuit (IC) and printed circuit board (PCB). 1 PCB Basics 1.1 Composition of PCB -Wiring the Pattern: the wiring is a tool to conduct the components, and a large copper surface is additionally designed to ground and used as the power. The wiring and the pattern
Modern PCB designs are expected to be high speed, multi-functioning, and have tight board space utilization. And, PCB materials must be of high quality, resistant to temperature variations, and easy to handle. One widely-used type of PCB dielectric material that exhibits many of these desirable qualities is FR4 material. In this article, we will discuss
High-density interconnect (HDI) printed circuit boards (PCBs) has recently become integral part of the electronics industries. Electronic components are becoming smaller and more lightweight but still demand of improvement is raising. Best way to fulfill this ever-growing requirement is to pack more functionality into a smaller area. That’s precisely what HDI PCBs offer. High density
If your project requirements have led you into considering a double-sided PCB design, it is important to understand the assembly process, the pros and cons, and other items you may want to look out for while putting together your design. Pros: Why Go Double-Sided PCB Most PCBs that are designed and built are single sided.
As we all know, an incorrect component placement during PCB assembly can create problems for the completed circuit board ranging from performance to manufacturability. Because these SMT placement issues can manifest themselves in vastly different ways, we will generalize them in the following eight categories: 1. Signal integrity SMT components that are not placed correctly
Managing heat is an important part of printed circuit board design and manufacturing. A board that isn’t designed to dissipate the heat it generates may end up with operational problems or even complete failure. During manufacturing it is also important that the heat be managed in order to withstand the high temperatures applied during the
Printed circuit board assemblies are very crucial requirement nowadays. More and more PCBs are being produced and are extensively in use. PCB assembly manufacturing contains numerous complex processes, and it’s going to be quite challenging to build it efficiently. Efficiency is necessary when it comes to PCB assembly manufacturing. Productive management of PCB assembly
Components that are placed too close to the edge of the board run the risk of being damaged or causing problems with other aspects of circuit board manufacturing. The problem is that some components have to be close to or on the edge of the board in order to perform their function. Connectors, switches, and
Starting a project without first counting the cost can end up being an expensive mistake, and this principle doesn’t apply to only large construction projects. Any project should be evaluated first for its cost to avoid unpleasant surprises, and this includes getting a printed circuit board manufactured. There are design for manufacturing (DFM) rules that
