PCB Design Tips:
All machining operations have finite errors, and milling in PCB production is no exception. JLCPCB’s regular milling tolerance is ±0.2 mm, with a precision ±0.1 mm option available. Due to these errors, it’s necessary to leave at least a 0.3 mm safety margin between any copper and a milled edge. Insufficient clearance can lead to damaged traces and pads, resulting in defective boards.
Problem and Solution
A milled slot on the board (purple) is placed too close to a nearby trace and cuts through the trace and a pad as a result.

Thermal Vias in PCB Design for Heat Management
Thermal vias are specialized vias designed to transfer heat from one layer of a PCB to another. These vias are placed near heat-generating components to create a thermal pathway, helping to dissipate heat and reduce the risk of overheating. They are often used with heat sinks, thermal pads, or copper planes to enhance their effectiveness. They are simply plated through holes (PTHs) that are located under a surface-mounted heat source component in a printed circuit board (PCB) that allow heat transfer.......
