Printed Circuit Assembly (PCA) boards are heavily populated with various electronic components like resistors, capacitors, integrated circuits etc. A reference designator unambiguously identifies a component within an electrical schematic or on a printed circuit board. The reference designator usually consists of one or two letters followed by a number, e.g., R13, C10 (where R is a reference prefix for the resistors of an assembly and C for capacitors). These markings/identifiers are visible text etched onto the PCA board and the text identifying the component is close in proximity to the component itself. The invention described here helps us to search/check the presence of such components over a board and locate them for detailed analysis.
