Three types of IoT PCBs: Class I, Class II and Class III
(Click on thumbnail to enlarge)
Just like the big boys (meaning conventional printed circuit boards), IoT PCBs fall under the categories of Class I, II and III.
Earlier, I noted that Class I IoT PCBs are pretty routine; those end applications cover virtually every consumer wearable you can think of. Class I IoT PCBs don’t demand a great measure of quality and reliability, for the simple reason that these products aren’t subjected to harsh or demanding environments that can affect proper operation.
So, in essence, Class I IoT PCBs don’t require the extra design, fabrication and assembly considerations that Class II and III IoT PCBs demand. For example, a Class I wearable product could be a sensor-based health-monitoring device that measures your heart beat, number of consumed calories or number of walking steps taken.
