PCB & PCBA Manufacturing File
Please provide detailed and accurate Gerber files and BOM lists required for PCB manufacturing and assembly, as well as other detailed parameter information.
The Files Required For PCB Manufacturing
| Files Required | Specification |
|---|---|
| Files Required | The PCB Manufacturing files we can accept is: Gerber RX-274X, .brd, .pcb, .pcbdoc, etc. |
| If you also have the stack-up or impedance control or other informations, feel free to send them together with the PCB manufacturing files. | |
| PCB Materials | Non-flame retardant board | flame retardant board | semi glass fiberboard | epoxy fiberglass board | high-frequency board | aluminum base board, etc |
| The Thickness of The Plate | 0.3mm | 0.5mm | 0.8mm | 1.0mm | 1.2mm | 1.6mm | 2.0mm, etc. |
| Mechanical Processes | Such as punching and cutting, CNC drilling and milling, palletizing process, V cutting, etc. |

| Special Requirements | To be provided upon special request. |
What is Gerber File?
Gerber file is computer software, is the circuit board industry software describes the circuit board (line layer, resistance layer, character layer, etc.) image and drilling, milling data document format collection, is the circuit board industry image conversion standard format.
The “Gerber Job File Editor” software can be downloaded from Ucamco’s website.

Why provide the Gerber file to the PCB manufacturer
Because electronic engineers and PCB engineers have a different understanding of PCB.
The GERBER files converted from the PCB factory may not be what you want.
For example, when designing PCB, you define the parameters of components in the PCB file, but you don’t want these parameters to be displayed on the PCB product. But if you don’t explain, the PCB factory will follow the instructions and leave these parameters on the PCB product.
The Files Required For PCBA PCB Assembly
| Files Required | Specification |
|---|---|
| Gerber files* | Gerber files in the format of RS-274X for PCB fabrication |
| BOM file* | BOM file in excel format for components sourcing and PCB assembly. It should include the basic information for each component: Reference Designators, Quantity, Manufacturer Part Number, Description, etc. |
| Pick & Place file* | Also known as Centroid file or XY data. It describes the position and orientation of all the surface mount parts, and it can help us quickly program the SMT assembly machines. |
| Assembly drawing (If you have) | It includes the positions and polarities of the components designators which can help us better understand your assembly needs, correct some ambiguous or even mistaken placements, and ends up with an excellent job. |
| Testing Guide & Test Fixtures (If you have) | To ensure the board’s quality, if you have a simple test guide for your PCBA boards that we can do, please let us know, and we can test all the boards before shipping. |
| Programming files & Programming tool (If necessary) | We could do IC programming for our customers if required. |
