In the rapidly evolving landscape of high-frequency data transmission and extreme environment operations, the demand for high-reliability gold finger connectors (PCB edge card connectors) has reached an unprecedented peak. These vital connection interfaces serve as the primary conduits for data, power, and signal transmission between peripheral expansion cards and maternal printed circuit boards (PCBs). From high-speed telecommunications infrastructure, enterprise AI computing clusters, to military-grade aerospace telemetry systems, gold finger connectors represent the critical threshold of system continuity and operational integrity.

Focusing on the fields of batteries, capacitors, and connectors, we use innovation as our spear, making every effort to overcome the technical bottlenecks of solid-state batteries, break through the upper limit of capacitor energy density, and develop high-precision and low-loss connectors.
We customize gold plating thickness from 3u" to 50u". Using electrodeposited hard gold over a nickel barrier layer, we prevent copper migration and secure over 10,000 mating cycles in heavy-wear environments.
Our design engineers enforce precise impedance control, targeting 85Ω and 100Ω parameters to eliminate signal reflections, catering specifically to high-speed PCIe Gen 5 and Gen 6 interfaces.
Our manufacturing line provides precise beveling angles (20°, 30°, or 45°) on PCB insertion edges to protect mating sockets from contact damage during blind-mate operations.

For standard components undergoing low mating cycles, a thickness of 3u" to 10u" is typical. However, for industrial, high-frequency, and military-grade applications where board insertion occurs frequently, a thickness of 30u" to 50u" of hard gold electroplated over a nickel barrier layer is required. Hard gold is alloyed with a small percentage of cobalt to dramatically improve wear resistance.
Dynalink optimizes high-speed signal pathways using advanced electromagnetic simulation. By using low-loss dielectric substrate materials (e.g., Megtron 6 or Rogers laminates) and managing tight tolerances on trace widths and spacing, we ensure that differential pair impedance is consistently maintained at 85Ω or 100Ω, minimizing cross-talk and insertion loss.
Chamfering involves creating a precise bevel (usually 20, 30, or 45 degrees) along the leading edge of the PCB card. Without proper chamfering, the sharp 90-degree edges of the FR4 board would scrape and damage the mating contact springs inside the female edge connector slot, causing immediate pin distortion or long-term contact degradation.
Yes, our in-house engineering and precision molding departments enable us to support custom pitches down to 0.50mm. We can modify pin counts, layout spacings, segment keys, and total board heights to perfectly match your proprietary system designs, including VPX, COM-Express, and custom backplane standards.
