An important part of the PCB design process is creating the footprints. Tiny mistakes during this stage may result in a failed design, no matter how clean and perfect your layout is. And the bad news is that is very easy to make mistakes during footprint creation if you don’t pay enough attention to what you are doing. That’s why you must include some degree of verification process to your
Imagine this situation: you had a great idea for a new electronic device or product, you have finished your schematic and completed the layout of your Printed Circuit Board (PCB). Now it’s time to send it to the manufacturer. No matter how good you are at electrical engineering or PCB design, you should always make a small batch of prototype PCBs before proceeding with a production order. But what is
Light Emitting Diodes (LEDs) are very popular these days. You can find LED arrays in a variety of products such as gaming, lighting, home decoration, or even in industrial human machine interfaces, just to name a few. Most LED products contain a Printed Circuit Board with LEDs and a built-in control logic circuit. Sometimes the control logic circuitry may reside on a separate board that connects to the LED PCB
Flexible circuits, also known as flex PCBs, are printed circuit boards that can be bent, twisted and folded because they have a substrate of flexible polyimide film and one or more thin layers of metallic material (usually copper). The copper layers are chemically etched to produce the desired circuit patterns. Adhesive is commonly used to bond the copper to the polyimide film, but other types of bonding can be used.
A via (also known as vertical interconnect access) is a copper plated hole that allows electrical connection between layers of a printed circuit board. The hole can be made using a drill or laser. A via consists of a barrel, a pad, and an anti-pad. Through-Hole Vias A through-hole via is a copper plated hole that traverses the entire printed circuit board from one top to bottom. It forms a
