Hidden Hazards and Precise Diagnostic Methods for High-Resistance Via Failures in PCBs

High-resistance via failure in PCBs is a highly concealed and hazardous latent defect, characterized by electrical continuity but with a resistance value far exceeding the standard (normal via resistance ≤50mΩ, while high-resistance vias ≥200mΩ). The resistance value is unstable and fluctuates with

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
