4 Layer PCB Gold Finger Circuit
The 4 Layer PCB Gold Finger Circuit from Gesp Technology Dalian Co., Ltd. is designed for high-density interconnect applications requiring robust signal integrity and durability. This board features a four-layer stack-up with gold-plated edge connectors, ensuring low-contact resistance and resistance to corrosion for repeated insertion cycles. The base material is FR4, a standard epoxy-fiberglass composite, with a typical Tg of 130 - 140°C for thermal stability under operating loads.
Gold fingers are plated to a typical thickness of 3 - 50 microinches, with a hardness range of 90 - 120 HR15T to withstand mechanical stress during mating. The board supports standard copper weights of 1 oz (35 µm) for inner and outer layers, with a typical dielectric thickness of 0.2 mm between layers. Via technology includes through-hole plating with a minimum hole diameter of 0.3 mm, standard for dense SMT assemblies, and a typical aspect ratio of 8:1 for reliable plating coverage.
This PCB is used in telecommunications equipment, industrial controls, and consumer devices where space constraints demand multi-layer routing. Buyers typically source these for prototypes or mid-volume production runs, with confirmation required for exact lead times and packaging formats. The gold finger design is particularly suited for edge-card connectors in servers, storage systems, and high-speed data acquisition modules.

Sourcing 4 Layer PCB Gold Finger Circuit from Gesp Technology Dalian Co., Ltd. - China Import Guide
Before ordering, verify the exact copper weight, gold finger plating thickness, and dielectric constant (Dk) to ensure compatibility with your circuit’s impedance and signal integrity requirements. Request a stack-up diagram and material datasheets from Gesp Technology Dalian Co., Ltd. to confirm these parameters, as they directly affect performance in high-frequency applications.
Confirm the packaging method, as PCBs with gold fingers require protection from mechanical damage and oxidation during transit. Standard options include vacuum-sealed bags with desiccant or anti-static foam inserts. Clarify whether the supplier uses FOB Dalian or CIF terms, and agree on payment milestones, as these impact landed costs and risk allocation for bulk shipments.
For quality assurance, require a first-article inspection report (FAIR) that includes cross-section analysis of the gold fingers and via plating. Ask for IPC-A-600 accept/reject criteria to be applied, and ensure the supplier can provide RoHS compliance test reports if your market requires it. Inspection at origin in Dalian is advisable for high-value or critical batches.
