Process work must be done to prepare the boards to be separated mechanically. This work is done through two methods: V-Scoring and tab routing. Both panelization methods find use depending on different design elements of the board. Below, it will be explored in greater detail and comparison-contrast.

A circuit board with this much different functionality is referred to as a mixed-signal design, and there is a lot of different electronic activity going on within it. To operate successfully, designers need to exercise caution in the layout of these boards to avoid signal and power integrity problems. Here are some PCB design rules for mixed-signal circuit boards that can help.

EMI/EMC is pervasive throughout the design and taking into consideration the many ways in which it can be accounted for, represents an opportunity for a discerning layout engineer to potentially limit EMI without the need for additional shielding. However, the balancing act of particular layout jobs may require that EMI/EMC is addressed via shielding materials after the finished board is prepared for a final inspection.

The fallout from the COVID-19 pandemic’s disruption of global supply lines has created a backlog that many industries are still mitigating. The best way to sidestep the international manufacturing gridlock is by onshoring supply chains. While a top-to-bottom restructuring of global industries does not happen overnight, there are still multitudes of solutions and benefits for national businesses that can be realized today.

PCB CMs understand both the fabrication and assembly side of manufacturing a circuit board, and they can choose the best PCB fabrication shop to work with to produce a high-quality board. Here’s how.

Flying probes have seen wide adoption over the past three-plus decades, especially in the realm of prototyping and other low-volume production runs. However, the advantages provided by a PCB flying probe test quickly erode when scaling for larger productions. An explanation of the PCB flying probe test, its benefits, drawbacks, and alternatives to the test are offered below.
