Double-Sided Greenened Gold Plate

Double-sided greenized gold plated board, using vacuum precision gold plating technology, the gold plating surface adopts ultra-thin uniform coating technology, with the gold layer thickness precisely controlled within 0.05 - 0.1 μm. This not only maintains excellent conductivity and solderability, but also significantly reduces the cost of precious metals. After high-temperature aging tests, it still shows no oxidation or color change. The board body selects high insulation FR-4 base material, combined with an optimized grounding layer design, effectively suppressing electromagnetic interference. It supports stable transmission of industrial-grade medium-low speed signals and is compatible with through-hole and surface-mount hybrid packaging, meeting the integration requirements of various types of components. It is suitable for industrial control auxiliary boards, smart home sensor modules, batch consumer electronic interface boards, front-end circuits of security monitoring, etc. It is a cost-effective PCB solution that balances production economy, production efficiency, and usage stability.

Product Overview

Double-Sided Green Solder Mask ENIG PCB is a two-layer PCB with green LPI solder mask and thin-layer ENIG plating on both sides. Gold thickness is controlled within 0.05-0.1 μm. It supports mixed through-hole and SMT component assembly. Plating thickness and substrate selection need confirmation according to project specifications.

Typical Applications

  • Industrial control auxiliary boards
  • Smart home sensor modules
  • Mass-volume consumer-electronic interface boards
  • Security-monitoring front-end circuits
  • Automotive non-safety-relevant interior auxiliary circuits

Key Features

  • Precisely controlled thin gold layer balances conductivity, solderability and precious-metal cost
  • Maintains anti-oxidation performance after high-temperature aging test
  • Green solder mask fits automated SMT vision positioning and AOI inspection
  • Optimized grounding layout helps suppress electromagnetic interference
  • Compatible with mixed through-hole plugin and SMT surface-mount devices

FAQ

Q: What is the benefit of thin-gold-layer ENIG process?
A: The thin and uniform gold layer keeps good conductivity and solderability while lowering precious-metal material cost compared with thick-gold ENIG boards.
