Complete schematic diagram and BOM (Bill of Materials) package output is the core valueadded service of highstandard PCB copy and cloning projects, enabling customers to obtain complete, editable, and producible PCB design data instead of only physical circuit boards. Most traditional lowend PCB copy services only provide finished circuit boards, without supporting design documents and material lists, resulting in customers being unable to carry out subsequent secondary development, fault maintenance, batch production, and technical iteration. Our professional PCB copy service provides a onestop schematic and BOM full package solution, realizing the perfect restoration of design logic and material information of the original board, and providing comprehensive technical support for customer equipment maintenance, product replication, and technical upgrading.

The schematic diagram restoration strictly follows the original circuit logic and electrical connection relationship of the physical PCB. Based on highprecision scanning data and circuit network analysis results, our engineers use professional electronic design software to redraw standard circuit schematics, including core circuit modules such as power supply circuit, signal acquisition circuit, control logic circuit, and drive output circuit. In the schematic drawing process, we standardize component symbols, circuit line definitions, and network label specifications, optimize circuit layout logic, and correct the nonstandard design and wiring defects of the original board. The final output schematic file supports multiple mainstream editable formats, with clear circuit hierarchy and complete signal flow marks, which is convenient for customers to view circuit principles, analyze fault points, and carry out secondary design modification.

The supporting BOM package is refined and sorted based on accurate component identification results, covering all components on the PCB without omission or error. The standardized BOM list includes detailed information such as component serial number, position number, model specification, electrical parameters, package type, quantity, manufacturer brand, and compatible alternative models. Different from simple material lists in the industry, our BOM package also adds procurement suggestions, component grade classification (industrial grade, commercial grade, military grade), and temperature resistance parameter descriptions, helping customers quickly complete component procurement and reduce procurement costs. The integrated schematic and BOM package forms a complete set of PCB reverse engineering data, which can be directly used for product proofing, mass production, technical filing, and aftersales maintenance. This service greatly improves the industrialization value of PCB copying, allowing customers to completely master the independent design and production rights of circuit board products.
