Method and System for Providing a Dual Functioning Interface and a Connector in a Printed Circuit Board

In a product assembly phase, the assembly needs to be connected to a card for programming and debugging at certain situations such as during assembly testing or prototyping. Generally, the assembly is routed to an additional port on a Printed Circuit Board (PCB) and a connector is populated for the prototyping phase. However, the connector is permanently removed (de-populated) from the port when the product goes into a production phase. Thus, the connector is not available for debugging once the product is in the production phase. If the connector is required during the production phase, the connector is soldered again on the PCB which is costly and time consuming process. Alternatively, a secondary connector can be permanently placed on the PCB. If the connector is placed on the faceplate of the PCB, then there can be confusion to the customer. An additional cost might be required to cover the port opening if the

connector is placed on the faceplate of the PCB.

Disclosed is a method and system for providing a dual functioning interface and a connector in a Printed Circuit Board (PCB). The method and system rotates a secondary PCB for changing an electrical path for the connector during debugging and programming of an Integrated Circuit (IC) card. For example, if an assembly (product) is to be shipped to a consumer, a Universal Serial Bus (USB) in the PCB talks to a Central Processing Unit (CPU). However, the secondary PCB is rotated 180 degrees of the same assembly during a debugging phase. In this configuration, the connector is configured as a serial port for communication with a Complex Programmable Logic Device (CPLD).

If an alternate position of the PCB is taken into consideration, an alternate port can be setup and may not require taking the entire product apart. As little as two fasteners are removed to flip the configuration. Thus, there is a significant time reduction compared to the rem...
