製品の定義
A Gold Finger PCB refers to a circuit board featuring a series of exposed, rectangular contact pads plated with thick gold (“fingers”) along one edge. These boards are designed for direct insertion into a matching connector slot, establishing a stable, pluggable connection for electrical signals and power between devices. この商品は、 12-多層PCB with a standard thickness of 1.60mm, offering an optimal balance between complex circuit integration and mechanical robustness.
設計上の重要な考慮事項
-
Gold Finger Area Design:
-
Chamfer (Bevel) Edge (Typically 20-45°): Facilitates smooth insertion into the connector—a critical aspect of ゴールドフィンガー プリント基板設計.
-
Lead-in (Trace Fanout): Connections from the gold fingers to internal traces must have smooth curves, avoiding right angles to prevent stress concentration and plating cracks.
-
Solder Mask Clearance (Solder Mask Define): The gold finger area requires precise solder mask opening to ensure a clean, exposed plating surface.
-
-
インピーダンス制御 & 信号の完全性: として 12-layer precision PCB, strict impedance control (例えば。, 50Ω シングルエンド, 100Ω差動) for high-speed signal layers is essential. Stack-up design must be optimized via simulation to minimize crosstalk.
-
熱 & Reliability Management: High-Tg material, coupled with a well-designed via structure, ensures the 多層PCB operates stably in elevated temperature environments. メッキスルーホール (pths) should be avoided at the root of gold fingers to prevent fluid entrapment and structural weakness.
それがどのように機能するか & 構造
This PCB facilitates complex circuit interconnections through its internal 12 導電層. The core functionality resides in the Hard Gold Plated Fingers. The durable 30-microinch gold plating provides excellent conductivity, 耐酸化性, そして耐摩耗性. When the board is inserted into a backplane or card-edge connector, the gold fingers make tight, low-resistance electrical contact with the connector’s spring contacts, transmitting signals and power. The board core uses FR-4 TG170, providing solid mechanical support and electrical insulation.
