High-Performance FR-4 Double-Sided PCB Visão geral do produto & Definição
Esse 2-Layer Rigid Placa de circuito impresso (PCB) from UGPCB is a fundamental and widely used electronic interconnect solution. It features a standard 1.6mm board thickness, dimensions of 224.02mm x 189mm, and utilizes high-grade KB FR-4 laminate. This double-sided PCB serves as the essential “backbone” for electronic designs, providing reliable electrical connections and mechanical support for components. It is an ideal, cost-effective choice for a vast range of industrial control, eletrônica de consumo, and power supply applications.
Critical Design Considerations
Successful design of a double-sided PCB requires balancing electrical performance with manufacturability. Key considerations include:
-
Routing Strategy: Efficiently utilize both top and bottom layers for trace routing. Plated Through-Holes (PTHs or Vias) enable inter-layer connections. Careful planning of trace density is crucial to prevent signal integrity issues like crosstalk.
-
Hole & Pad Design: Specify appropriate drill sizes and pad diameters for all PCB vias and component leads to ensure mechanical strength and soldering reliability, aderência a Padrões IPC for annular ring.
-
Poder & Ground Planes: While dedicated planes are absent, designers should widen power and ground traces or implement a gridded copper pour to reduce impedance and enhance stability—a key aspect of robust Projeto de PCB.
-
Design Rule Check (DRC): Prior to fabrication, rigorously verify that all parameters (trace width/clearance, hole sizes) align with the manufacturer’s capabilities (as per this board’s specs) to guarantee PCB design for manufacturability (Dfm).
Princípio de funcionamento & Estrutura
The functionality of this double-layer circuit board stems from its layered structure:
-
Construção: The core consists of an FR-4 insulating dielectric layer, clad with copper foil (tipicamente 1 onças) on both sides. The unwanted copper is etched away during Fabricação de PCB, forming the desired circuit traces.
-
Electrical Interconnection: Circuits on the two layers are connected vertically via Plated Through-Holes (PThs), created through mechanical drilling followed by electroless and electrolytic copper deposition.
-
Surface Protection: O Lead-Free Hot Air Solder Leveling (Sangrar) finish applied to exposed copper pads prevents oxidation and ensures excellent solderability for component assembly.
