Abstract: In one example, the present application describes a Printed Circuit Board (PCB) that mitigates galvanic corrosion during an Organic Solderability Preservative (OSP) process used during fabrication of the PCB. The PCB includes a first metal pattern and a second metal pattern electrically coupled to each other, where the first and second metal patterns are different metals. The first metal pattern has a first area that is exposed by a solder mask layer, and the second metal pattern has a second area that is exposed by the solder mask area. A ratio of the first area to the second area is less than a threshold ratio to mitigate the galvanic corrosion of the second metal pattern exposed on the PCB during the OSP process.

Abstract: Devices and methods are described for reducing etching due to Galvanic Effect within a printed circuit board (PCB) that may be used in an electronic device. Specifically, a contact trace is coupled to a contact finger that has a substantially larger surface area than the contact trace. The contact finger is configured to couple the electronic device to a host device. The contact trace is electrically isolated from the rest of the PCB circuitry during a fabrication process by a separation distance between an exposed portion of the contact trace and an impedance trace. The contact finger and the exposed portion of the contact trace are plated with a common material to reduce galvanic etching of the contact trace during fabrication. The contact trace is then connected to the impedance trace using a solder joint.
