What production materials are needed for PCBA processing?

When customers provide production materials to PCBA processing manufacturers, they generally need to prepare the following production materials list:

PCB Gerber file (a layered file that defines each layer of circuits, pads, silk screens and other information, used to manufacture PCB bare boards)

BOM list (Bill of Material, a list of electronic components, including the model, brand, description, position number and usage information of components)

MCU program (generally refers to the chip program burned into the MCU, an encrypted file in hex or bin format, used to drive the entire PCBA logical operation and bypass control)

Test file (defines the test point distribution, test steps and common fault diagnosis methods for functional testing)

Upper computer software (generally refers to software installed on the computer to start the detection of PCBA function items)

Patch coordinate file (exported from PCB design software, defines the coordinate position of each component on the PCB board, which is convenient for SMT placement machines to read and execute)

Other design documents (such as CAD drawings that define the effect diagram after welding, PCB schematics, special requirements for engineering processes, etc.)
