PCB thermal conductivity influences all design aspects, beginning with stack-up and material choices and continuing through the layout. External heatsinks can be included in the design further to reduce heat buildup on or within the board.
Here, we’ll look at some of the problems to avoid during soldering and some of the best practice PCB soldering techniques that can help.
When it comes to the best PCB materials, it is of utmost importance to first consider the function of the underpinning physics driving the final product’s function.
Everything from diagnostic equipment to blood analysis systems relies on electronics that must function perfectly every time. This level of reliability requires absolute precision and quality in the design and manufacturing of PCBs for medical devices, which we will examine in greater detail here.
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.
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.
