Product Description

​What Is Double-Sided Gold Immersion Circuit Board?
Double-sided gold immersion circuit board is a type of printed circuit board where a uniform gold layer is formed on both sides of the substrate through a chemical deposition process. Its surface treatment process is as follows: first, a thin nickel layer is deposited as the base, and then a dense gold layer is covered on the nickel layer. The thickness of the gold layer is controllable (usually 0.05-0.1μm), the overall surface is flat and smooth, and both sides have consistent plating performance. The circuit board adopts a double-sided wiring design, which can meet the signal transmission needs of small and medium complexity circuits and is suitable for the welding and assembly of various precision components.

Main Advantages

Excellent solderability and stability: The gold layer has good conductivity and strong oxidation resistance, which can maintain good welding performance for a long time. It is especially suitable for high-frequency welding or the welding of precision components (such as BGA, QFP), reducing the risk of cold solder joints and false welding.

Excellent corrosion resistance and wear resistance: The nickel layer and gold layer form double protection, which can resist the influence of complex environments such as humidity, high temperature, and chemical corrosion, and extend the service life and storage period of the circuit board (room temperature storage can reach more than 12 months).

Suitable for high-frequency and precision scenarios: The flat gold layer surface can reduce signal transmission loss, improve the stability of high-frequency signals, and is suitable for fields with high requirements for signal quality such as communication equipment and medical instruments.

Strong process compatibility: The gold immersion process has good adaptability to the size and line density of the circuit board, can match a variety of substrates (such as FR-4), and the production process is more environmentally friendly than some lead-containing processes, meeting the environmental protection requirements of modern electronic manufacturing.



  • FAQ:

    1.Q:How many layers can your circuit boards provide?

      A:We typically provide 1-30 layer boards, and in special cases, we can stack more layers.

    2. Q:Do your circuit boards support customization?

        A:Yes, we support customized designs. You can send us your Gerber files and BOM list, and we will provide you with an accurate quote based on the information and market conditions.

    3. Q:What do Gerber files typically contain?

        A:Normally Gerber files Include:PCB Types,Product thickness, Ink color, Surface treatment process and If SMT processing is required, component BOM and tag drawing are also required.
    4. Q:What is your minimum order quantity for PCB boards?

        A:Our minimum order quantity is 1 piece(5 square meters),the larger the quantity, the bigger the discount.

    5. Q:Do you have relevant certification certificates to support this?

        A:We hold numerous important certifications, including ISO, UL, CE, and RoHS. All products undergo rigorous quality testing.

    6. Q:What payment method do you usually use?

        A:For small orders, samples, or urgent payments, we accept Western Union. For large orders, we recommend T/T, which ensures the safety of both parties.

The red oil laminated boards are tightly bonded with no delamination, produce a crisp sound when tapped, and passed all tests on the first try, without delaying the project schedule at all. The price for mass production is very reasonable, making them a supplier worth cooperating with long-term.

Upon receiving the order, I noticed that two of the circuit boards had slight exposed copper at the edges of the solder mask. After contacting customer service, they quickly sent replacements. Their after-sales service is commendable.
