Description Of Golden Finger HDI Printed Circuit Board:

Insert one end of the circuit board into the connector card slot, use the pins of the connector as the outlet for external connection of the circuit board, make the pad or copper contact with the corresponding pins to achieve the purpose of conduction, and connect the circuit board Nickel gold is plated on this pad or copper skin, and it is called a gold finger because it is in the shape of a finger.

The standard hard gold plating method adopts electroplating method, which requires all fingers to be conductive during electroplating, so a wire will be added under the gold finger, firstly plate a layer of dielectric nickel on the copper surface, and then plate gold on the nickel layer according to the required thickness .

Before the fingers are gold-plated, cover all other non-gold-plated pads with tape, tear off the tape after gold-plating, and then cover the gold fingers with tape, and other pads are treated with tin spraying, OSP, and gold as required, and the pads are treated Peel off the tape on the gold finger after completion.

During molding, the gold fingers are bevelled to facilitate insertion into the card slot.
