The July issue of The PCB Design Magazine is now available. This issue focuses on PCB design in the military and aerospace segments. As we found while putting this issue together, mil/aero work is not for those managers with an aversion to paperwork or cybersecurity regs, or anyone who needs to be paid quickly.
Read all about it this month in The PCB Design Magazine, now on the virtual newsstand and available for delivery in your e-mail inbox by subscribing here.

The design process is arguably the most important part of the flex circuit procurement process. The decisions made in the design process will have a lasting impact, for better or worse, throughout the manufacturing cycle. In advance of providing important details about the actual construction of the flex circuit, it is of value to provide some sort of understanding of the expected use environment for the finished product.

Using powerful constraint techniques can be a double-edged sword. While the design process is made much safer by including constraints, it is all too easy to over-constrain the design and make it impossible to complete routing and placement. Even paper design guidelines can make products uneconomic to produce unless a great deal of engineering knowledge is applied during the design.

Ready or not, 5G is coming, and it will require the right circuit materials for many different types of high-frequency circuits, including power amplifiers. 5G represents the latest and greatest in wireless technology, and it will be challenging to design and fabricate, starting with the circuit board materials, because it will operate across many different frequencies, such as 6 GHz and below, as well as at millimeter-wave frequencies (typically 30 GHz and above).
