UGPCB Factory’s VCP Equipment: Innovation and Technological Breakthroughs in Vertical Continuous Plating
Introduction: Core Equipment Innovation in PCB Manufacturing
Driven by industries such as 5G communication, artificial intelligence, and new energy vehicles, PCB (Printed Circuit Board) technology is advancing toward high-density interconnect (HDI), any layer interconnection, and other high-end fields. As the core equipment in PCB electroplating processes, Vertical Continuous Plating (VCP) technology has become a key indicator of manufacturers’ technological capabilities. UGPCB’s heavily invested modern, intelligent VCP equipment is redefining production standards in the PCB electroplating industry through its precision transmission system, high electroplating efficiency, and environmentally friendly process design.
1. VCP Equipment Structure and Operating Principles
1.1 Core Equipment Structure Analysis
UGPCB’s VCP system primarily consists of three integrated components:
- Plating Tank Array: Modular design with vertically arranged independent units, each equipped with precision fluid control systems. Tank bodies use PP/PVC composite materials ensuring corrosion resistance and chemical compatibility.
- Transmission Mechanical Arm System: Servo motor-driven chain transmission mechanism enables precise PCB board transfer between tanks. Titanium alloy arms resist acid/alkali corrosion with positioning accuracy of ±0.05mm.
- Intelligent Control Center: Integrates PLC and industrial IoT technology for real-time monitoring of parameters like current density (3.0-3.5ASD), plating duration (20-40min), and transmission speed (0.5-2m/min). Supports MES system integration.
1.2 Electrochemical Copper Plating Principles
VCP follows Faraday’s laws of electrolysis (Formula: M=K⋅I⋅t) through anode dissolution and cathode deposition. Technological innovations include:
- Flow Field Optimization: Dual-tank design with upper tank jet flow creating uniform eddy currents and lower tank achieving 6m³/h chemical circulation filtration, ensuring plating uniformity (R value ≤5μm).
- Energy-Saving Performance: Compared to traditional龙门式 equipment, VCP reduces copper consumption by 13%, water usage by 60%, and power consumption by 30%, complying with EU RoHS and REACH regulations.
