There are many different tests and inspections that a circuit board will go through during manufacturing. Some of these tests are designed to catch specific problems or conditions, while others are more general. All testing culminates with the final functional test to ensure that the board is ready to operate. This article will examine these different tests and explore the benefits of PCB functional testing methods.

Help is available for quality control through automated optical inspection systems (AOI). Here are more details on how PCB fault detection using image processing will assist with printed circuit board inspections.

In PCB design, it isn’t uncommon for junior designers to quickly throw components into a layout to move to the “fun” part of routing the traces. With PCB design, as with bridges, all the work can be wasted effort if the substrate isn’t designed correctly. Therefore, it is essential first to configure the layer stackup of the board to support the needs of the design. Here are some more details about the importance of PCB stackup design and what to be aware of before going into the layout.

Circuit boards have an analysis process they can go through when they suffer a failure. Although a PCB failure doesn’t command the same amount of attention as an accident, it is still essential to understanding the error and preventing it from happening again. Here is a closer look at failure analysis in circuit board systems to better understand this aspect of PCB design and development.

The PCB designer career field is projected to continue growing for the foreseeable future, and designers earn far above the average annual income in the United States. If this sounds like a career field that you would be interested in, keep reading. There’s a lot more to tell about becoming a PCB designer.

While your PCB layout will never be completely rid of parasitics, you can reduce parasitic capacitance in a PCB layout or take some steps to limit its effects on signal and power integrity. Whether you’re engaging with a PCB service bureau or creating the layout yourself, follow some guidelines to ensure parasitic capacitance does not cause your design to fail.
