Core Logic and Engineering Baseline of PCB Via Pitch

Core Logic and Engineering Baseline of PCB Via Pitch

In multilayer PCB design, vias are the central hubs for interlayer signal and power interconnects. While Via Pitch may seem like a basic process parameter, it directly dictates PCB mass production yield, signal integrity (SI), and EMC compliance. Numerous engineering cases show that over 70% of high

Out-of-Control Costs in 4-Layer PCB Rush Production? Material Selection & Scheduling Logic

Out-of-Control Costs in 4-Layer PCB Rush Production? Material Selection & Scheduling Logic

There are two prevailing extreme mindsets in the industry: one insists that rush orders require expensive materials to guarantee quality, while the other prioritizes cheap materials to cut costs when rushing production. In reality, cost control for 4-layer rush production hinges on demand-based tier

Core Principles and Full-Scenario Design of PCB Shielding Technology

Core Principles and Full-Scenario Design of PCB Shielding Technology

If decoupling technology suppresses noise from "within the power supply," shielding technology blocks noise propagation from the "external environment." The two complement each other, forming the twin pillars of PCB noise reduction. In high-speed, RF (Radio Frequency), and high-EMI-sensitive scenari
