Printed circuit boards (PCBs) are essential components of modern electronics. They are used in everything from smartphones to spacecraft and are critical to the functioning of these devices. As such, maximizing efficiency in PCB production is crucial to ensure the timely and cost-effective manufacturing of electronic devices. One way to maximize efficiency in PCB production is to […]
Printed circuit boards (PCBs) are an essential component of modern electronics, providing a platform for connecting and controlling electronic components. Over the years, PCBs have undergone significant changes in design, materials, and manufacturing processes. In this essay, we will explore the future of printed circuit boards by examining current trends and developments. One of the […]
There’s increased pressure for companies to address environmental sustainability of their products which impacts electronic assembly and printed circuit board manufacturing. Climate change and recycling practices are driving sustainable PCB manufacturing. Introduction of hazardous material use standards and alternative manufacturing options are contributing to the progress achieved. PCB manufacturing has traditionally posed some environmental concerns like: energy-intensive high […]
Types of material available. Circuit Board Material The circuit board is made up of the core (substrate) and the laminate. The core is the dielectric (non-conductive) portion chosen based on dielectric constant. Laminates provide the copper foil or surface. Laminates themselves, may also be used as core material in some constructions. Substrates Substrates are dielectric composite […]
Printed circuit boards have continued to advance and evolve since their invention back in the 1940’s. Today, PCBs are smaller, thinner, and denser in circuitry, than could ever be imagined at the beginning. They are also produced more efficiently and at higher volumes due to enhanced manufacturing technology and design software sophistication. As a key […]
Key material performance parameters are used to determine suitability of PCB materials for high frequency PCB applications. These include dissipation factor (Df), and dielectric constant (Dk). For digital circuits, and their steadily rising speed requirements, choosing the wrong PCB materials can have devastating results (such as poor plated-through holes or impedance discontinuities). Material selection based on these […]
PCBs are simply an electronic component base where various components are positioned and soldered in place. PCBs are made by etching the copper layer on the core laminate with the electrical circuit (layout). The most popular method is based on utilizing a ferric chloride solution, although there are methods available as well. If etching is improper, […]
PCB material selection and manufacturing process understanding is important to consider when contemplating a new project. One question is often, the difference between PCB core and prepreg materials. Once the difference between core and prepreg is understood, then what exact materials should be used for your application? What’s the impact on electrical parameters during plating, etching, […]
Halogen Free PCBs are printed circuit board without halogens in their construction. Halogens include Chlorine, Bromine, Fluorine, Iodine, and Astatine, which have health & safety concerns. For a PCB to be considered “Halogen-Free,” there must either be less than 900 parts per million of chlorine or bromine, or fewer than 1500 parts per million of […]
In PCB application, all gold is 99.9% pure. So efficiency in selecting the most appropriate process and thickness is very important to keep your product as cost-effective as possible. There are multiple types of gold finishes which can be applied to printed circuit boards, depending on the functionality required. ENIG (Electroless Nickel plating under Immersion […]
