Introduction: Despite a 30-50% manufacturing cost premium and 85-90% yield rates, 4-layer PCBs secure essential RF stability for 15-30mm pet trackers. 1.Engineering Context of Pet Tracker PCB Layer Count The debate between two and four copper layers in wearable electronics remains a critical engineering juncture. Defining a basic pet tracker involves identifying a device solely supporting location acquisition, typically Global Positioning System or Global Navigation Satellite System, paired with optional Bluetooth Low Energy or cellular connectivity. Such devices usually include fundamental activity detection via accelerometers but omit complex health sensors or cameras. Comparing these configurations reveals distinct application trajectories in the Internet of Things sector. The dual-layer approach caters heavily to entry-level, cost-sensitive projects. Conversely, adding internal planes caters to high integration densities and stringent radio frequency demands. Th...
