Circuit Board Gold Fingers
Product Description
Circuit Board Gold Fingers
In the realm of PCB assembly and manufacturing, there are three different methods that come with printing the prototype PCB`s legend. The legend is what the engineer uses to figure out the component designators, switch settings, and test points - all helpful components need when assembling, testing, and servicing the prototype circuit boards.
However, there are more details that go into this legend, including gold plating. Here is a beginner`s guide to this specific PCB fabrication process.
Gold finger is the gold-plated connectors that are on the edges of the printed circuit board prototype. They are similar to fingers in that they are long and narrow.
What are Circuit Board Gold Fingers made from?
The specifications for these have to be exact; flash gold must be used and the thickness cannot go over 3Us to 50Us. This is so the flash gold, which is one of the hardest golds available, will last a long amount of time and won`t need repair.
What is Circuit Board Gold Fingers purpose?
Gold fingers are edge connector contacts and are used to electroplate pads onto the board. The idea behind a gold finger is to help protect the printed circuit board prototypes from wear and tear. If applied correctly, with the right thickness, they are expected to last upwards of 1,000 cycles before there is any need of repair.
How are Circuit Board Gold Fingers used?
These little fingers are quite versatile, and they have many different uses depending on their intended purpose. Some of these uses include:
- Provides connections for network transfer data.
- Attaches specialty adaptors.
- Connects different devices to the board.
- Can be used as audio adaptors.
- Are there specific design specifications?
Yes. As we mentioned previously, there are some specifications depending on the need and use of the board. However, despite this, there are some design rules that must be followed no matter the board`s intended purpose. This includes:
- No plated through holes can be included anywhere near the gold fingers.
- No soldermask or screen printing can be included near the gold fingers.
- The gold fingers should always be placed facing outward of the board`s center.

PCB Shipment
JHY PCB offers flexible shipping methods for our customers, you may choose from one of the methods below.
Shipping Process
After production and testing, your PCB orders will be sent to our shipping department. As the Gold Fingers PCB manufacturer, JHY PCB shipping department will ship your PCB quickly without any pending.
JHY PCB 's Packing Way
- Use one professional PCB vacuum bag, with desiccant inside. Vacuum compressed totally.
- Paste label and RoHs mark. Use second vacuum bag to protect boards again, vacuum compressed, make sure no exception.
- Microsection report and Tin testing board are put together with PCB in cartons.COC (Certificate of Conformity) will be sent to customer by email in PDF.
- Several layers of thick EPE(Expand aple poly ephylene) are filled fully in gaps between PCBs and cartons. Thickness of 1 layer EPE is 10mm.
- Neutral Packing is adopted if no special requirements. Strong and thick cartons(Thickness:10mm,7 layers). Different sizes of cartons are designed to meet demand of different PCB size. All package are within weight limit of cartons. For mass production order, no exceed 21kg per carton normally.
- All cartons sealed with strong adhesive tape should be sealed twice so as to make them more durable.
- Solid PP/PET strapping is used outside of cartons.
- Shipping mark, fragile mark and postcode label are all pasted clearly.
