4-layer PCB With Hard Gold
This 4-layer PCB features a selective hard gold coating of 50 microinches (1.25 micrometers), designed for applications requiring superior wear resistance and low contact resistance. The board uses FR4 material with a thickness of 1.6 mm and a copper thickness of 1 oz per layer, making it suitable for consumer electronics where durability and signal integrity are paramount. The green solder mask provides insulation and protection against environmental contaminants.
Hard gold plating is applied selectively to specific areas such as connector pads or edge contacts, where its hardness and corrosion resistance extend the product’s lifespan. The PCB’s minimum drill size is 0.2 mm, and the minimum track and clearance are 0.125 mm, enabling dense component placement. The surface finish combines submerged gold with selective hard gold, ensuring compatibility with both soldering and contact-based interfaces.
The PCB is UL-recognised and complies with RoHS requirements, making it suitable for markets with strict environmental regulations. O-Leading Supply Chain (hk) Co., Limited also offers turnkey EMS services, including material procurement, SMT, and through-hole assembly, providing a streamlined solution for buyers needing fully assembled products. Confirm the exact scope of assembly services and their impact on lead times.

Sourcing 4-layer PCB With Hard Gold from O-Leading Supply Chain (hk) Co., Limited - China Import Guide
Before ordering, confirm the exact hard gold plating specifications, including thickness, coverage areas, and hardness values. Hard gold is typically applied to contact points, but the supplier should clarify whether it is used for through-holes or surface pads. Additionally, request a sample to validate the plating quality and its compatibility with your connectors or edge contacts.
Logistics and lead times for hard gold PCBs may differ from standard PCBs due to the additional plating process. Standard lead times for 4-layer PCBs with hard gold can range from 7 to 14 working days, depending on the order volume and plating complexity. Confirm whether the supplier offers DDP or FOB Incoterms, and clarify their policy on handling customs duties for international shipments.
Quality checks for hard gold PCBs should include visual inspection for plating uniformity, adhesion testing, and electrical continuity checks. Request the supplier’s quality control process documentation, particularly for hard gold deposition, which should align with IPC-4552 or MIL-G-45204 standards. Inspection reports should detail plating thickness, adhesion test results, and any deviations from specifications.
