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.
PCBs also need to be tested, which require test points to be strategically designed into the board along with placing the components and routing the connections. Bare board continuity testing, in-circuit test, and flying probe testing all require the presence of test points on the board to facilitate their processes. Here we will look at the top seven PCB test points layout strategies that designers need to understand to build a fully testable circuit board.
Efforts are underway to reshoring semiconductor manufacturing, but the time it takes to design, build, furnish, and staff a foundry means these efforts will not bear fruit for several years. Stateside printed circuit board manufacturing possesses numerous advantages over traditional global fabrication and assembly chains, and some of the reasons are outlined below.
