A circuit board can be the recipient of EMI unless preventative measures are taken in its design. The PCB you design can also create EMI with other electronics if you don’t take the same precautions. This article will look at some of these precautions and how to avoid electromagnetic interference in PCB designs.

The circuit boards we design also require extra effort when laying them out for high-speed circuitry. Sensitive nets must be routed according to specific high-speed rules and many other high-speed design requirements that must be followed. These include everything from how the schematic is organized to the placement of the components. We will look at all of this as we discuss the high-speed routing techniques to help you cross the finish line with your next PCB design.
Counterfeiting problems in electronics go far beyond batteries, extending all across the industry. Not only do these pseudo parts potentially damage the quality of the products that they are used in, but they are also a severe drain on the legitimate component industry. The best defense against a problem like this is to expose it and discover ways to prevent its spread. Here is information on counterfeit electronic components and what you can do to protect yourself.
Printed circuit boards are also coated or plated for their protection, and often this is done with a surface finish of solder or some other material. Not only does this help to protect the exposed metal on the board from corrosion, but it helps with component soldering. These aren’t the only plating processes used to fabricate a circuit board. Here is a more in-depth look at the different PCB plating processes used during circuit board manufacturing.
Design engineers expect to partner with their manufacturers to ask questions and work through changes, a challenging process when dealing with offshore vendors. In addition to the lack of personal service, shipping costs and time delays can impact an electronic project’s development schedule. Let’s take a closer look at these hindrances and how a US-based PCB manufacturer can resolve them.
You can lower the cost of a PCB if you design it as a double-sided board, but you may strangle its performance by doing so. Using multiple board layers can increase electrical performance to outweigh the differences in cost. Here are some of the advantages of multilayer PCBs and how you can best benefit from them.
