As part of the design and build process of print circuit boards, part numbers are use to ensure that electronic devices can be repair or replaced when they fail. During manufacturing By all means the Circuit Board Design, the manufacturer may change parts or the entire design as the boards are manufacture over months or years.
A serial number may be assign to a board to facilitate repairs and modifications. By tracing the parts installed, technicians can ensure that they are the right Pcb Assembly.
1. The built-up circuit board’s part number can be found on the board. Two numbers may be print on a board in many cases.
By all means circuit boards with Electronic Components are identifies by individual part numbers. In addition, there will be a part number for the complete board, including all its components. Circuit cards are sometimes calls circuit card assemblies (CCAs) to distinguish them from basic boards without components.
There may be an ink stamp or handwritten serial number near the CCA number. In general, they are alphanumeric or hexadecimal numbers that are short.
2. On large wiring traces and ground planes, look for a part number. These are copper pieces with solder coating, which may contain a logo, a CCA number, or even a patent number.
Coupled with serial numbers can be easily identify by adding “SN” or “S/N” to handwritten numbers. On small stickers affixed near the CCA part number, you can find some serial numbers. The serial number and part number are sometimes barcoded.
3. By all means access serial number information from computer memory using a serial data communication program. Professional repair facilities are the most likely places to find this method of extracting computer information. Automatic test equipment typically contains a subroutine to retrieve serial numbers, identification and modification status for CCAs, and even individual microcircuit identifications.
Coupled with a computer’s present status, including the serial number, modification status, and more, can be retrieve by entering “PS” on the command line. These simple queries can be answer with serial data communications programs.
