1、Dimensional multi-layer circuit boardProcess steps: require 10+processes including inner layer graphic transfer, lamination alignment, laser drilling, hole metallization, etcAlignment accuracy: interlayer tolerance ≤ 75 μ m, dependent on temperature and humidity control and high-precision position

1、 Core process technologyThe production process of single-sided PCB is simpler than that of laminated boards, but it requires precise control of key links to avoid defects:Basic process:Copper coated substrate cutting → graphic transfer (photochemical method or screen printing) → etching (removal o

1、 Application differences classified by layers and structures1. Single panel (single-layer panel)Technical features: Only single-sided copper-clad, the substrate is mostly paper-based phenolic resin (such as 94HB/94V0) or composite substrate (CEM-1), with low cost but low wiring density.Typical app

The Unsung Hero of Electronics: A Deep Dive into Single-Sided PCBsIn the dazzling world of modern electronics, with its multi-layered, high-density boards packing billions of transistors, it's easy to overlook the simple foundations that made it all possible. Today, we're paying tribute to one of th

Double the Layers, Double the Power: A Beginner's Guide to Double-Sided PCBsIf you've ever opened up an electronic gadget, you've seen the heart of the device: the Printed Circuit Board (PCB). That green (or sometimes blue, red, or black) board with intricate copper lines is what brings electronics
