Types and Specifications of JLCPCB Slots

JLCPCB distinguishes between two primary types of slots: plated and non-platedI wanted a camera that doesn't exist — so I built it.

* Plated Slots: These are slots where the internal walls are plated with copper, electrically connecting them to the surrounding circuitryPlated Slots with Eagle at JLPCB The Plated Slots Min requirement from JLCPCB is generally more restrictive than for non-plated ones, reflecting the added complexity of the plating process20221113—The two rules they specifically call out for Alu, in place of the regular rules are - minimum 1mm drill -minimum 1.6mm slot. For plated slots, JLCPCB specifies a minimum width of 0Problem with JLCPCB order designed with EasyEda50mm, with the pad size being enlarged by 0JLCPCB Aluminum PCB manufacturing notes + USB 5mm to ensure proper plating coverageI made this parts withJLCPCBand generally I was surprised by the precision, most of the things came into place perfectly, but few of them,  The process for creating plated slots at JLCPCB typically involves using layers, vias, or elongated pads combined with milling on specific layers (Layer 46 is mentioned in some contexts for this purpose)2023322—I've used Elecrow in the past, but the same should apply to JLCPCB.Slots outline should be drawn on the mechanical layer(the same as PCB
