Full Body and Selective PCB Hard Gold Plating
Full Body Hard Gold is generally a rarely-chosen surface finish, where the full body of the PCB board is plated with hard gold. In order to apply a Full Body Hard Gold surface finish, an electrolytic process using an electric current or an immersion process is needed, depending on the PCB design. For Complete PCB Assembly projects, where we fabricate and assemble the boards, we will also need to consider the poor solderability of this finish; a very active flux will be required to solder effectively to the hard-gold-plated pad.
At Bittele, we offer a few options for gold surface finishes to which we can adapt our PCB Assembly Process, providing our clients with the utmost flexibility while still supporting our meticulous PCB Quality Management standards.
Selective Gold involves using a hard gold surface finish to plate specific areas on a PCB. Please note that for quotation purposes, “Gold Fingers” are treated as a separate entity, so you do not need to ask for a Selective Gold surface finish just to cover those edge connectors. The application process for Selective Gold is nearly the same as Full Body Hard Gold, but the Selective method does require some masking that will accrue additional labour charges, balanced out by decreased material cost.
At Bittele, we offer both Full-Body and Selective PCB Hard Gold surface finishes, but please note that the associated cost of these methods depend largely upon the specific amount of gold that will be required. To maximize efficiency, please send an Assembly Drawing ahead of your main PCB Design Files so that we can collaborate with our production team and develop a plan.
