How Fast Can PCB Prototyping Ship?

PCB prototyping speed is critical for R&D cycles, with lead times primarily determined by layer count, panel size, and process complexity. For standard 2-layer boards under 1m², the fastest manufacturers offer 24-hour rush delivery; 4-layer boards take ~48 hours, 6–8 layers ~72 hours, and 10+ layers

How to Control the Uniformity of Hole Wall Copper Thickness in Thick Copper PCB

Controlling the uniformity of hole wall copper thickness is a core technical challenge in the manufacturing of thick copper PCBs, as uneven copper thickness can lead to poor conductivity, insufficient current-carrying capacity, and even premature failure of the board. Thick copper PCBs, defined by a
