The PCB serial number is part of the label and is responsible for tracking the parts or components welded to the board for modification or repair in the event of a failure. Most manufacturers use polyimide labels because they can withstand the heat in the reflow oven. Therefore, cardboard labels help to track production and storage parameters to improve production efficiency. If the manufacturer is aware of an error in the manufacturing or storage process, this PCB identification data can be used to track the part for recall.Īlthough it is not common, errors may still occur, especially when dealing with tiny parts. The label ensures that the circuit board gets the correct and required components. These tags contain the following information. What is a PCB label?Ī circuit board label is a sticker with information that is used to track the electrical components used in the production, storage, and installation of a PCB. Let's take a look at the importance of this label and the serial number written on that sticker, plus the PCB serial number lookup process. The label contains key data, one of which is the PCB serial number. Printed circuit boards go through a complex manufacturing and assembly process, so there must be labels to help identify where each board passes and the components it contains. The process of finding the circuit board serial number is essential for traceability and maintenance.
