What Role Does Documentation Play in PCB Assembly Processes?
Documentation Play in PCB Assembly Processes
PCB assembly is a highly precise, technical process. In order to ensure that the final product meets every spec exactly, manufacturers depend on several types of documentation. In this article, we will discuss the key components that make up a comprehensive documentation package and describe how they play a role in the overall assembly process.
To start, it is important to understand the different kinds of documents that comprise a PCB’s file package. The most crucial document is the bill of materials (BOM), which contains a list of all the component parts that will be used on the board. This information is also required for the fabrication and assembly drawings.
Next up is the Gerber and drill files, which are used to communicate the design intent of a printed circuit board assembly to the fabricator. These are typically provided in the form of a text or pdf file. These files contain all the necessary information to generate a fabricated board according to the designer’s specifications and requirements. They include the netlist, hole to edge dimensions, and a list of specific slots, notches, and cutouts.
Once the fab and drill files have been generated, they are then used to create the board’s manufacturing data. This is a critical step in the design-to-fabrication (D2F) process, and it is vital for accurate production. The CM will use this information to verify the correct placement of all the component holes and signals on the board, as well as the size, location, and diameter of the individual holes.

Lastly, the CM will use the assembly drawing to identify the position of each component on the board. This is important for a number of reasons, including ensuring that each part is placed in the correct location and that all components are oriented correctly. The assembly notes can also help the CM to determine if there are any special handling requirements for the particular component, such as the fact that it needs to be inserted with a certain amount of force or is sensitive to wave soldering conditions.
Precise assembly notes are a crucial part of the documentation package that will allow your CM to efficiently assemble your circuit boards. They can be provided in the form of a text or PDF file and provide detailed instructions for placing all the components on the board. These can include references to the centroid file or the corresponding reference designator for each component and their quantity.
The proper use of PCB documentation can drastically reduce the time and cost of a production run. Using tools like LiveDoc, which allows you to seamlessly generate all of the above documents, will help you to create a clear and detailed file package that can be used in the fab, assembly and inspection processes. This will minimize human error and enable the CM to complete the assembly and testing process as quickly as possible.
