PCB Assembly Visualizer checks PCB, BOM and CPL

PCB Assembly Visualizer checks PCB, BOM and CPL:

After the printed circuit board (PCB) has been designed and manufactured, it must be filled with electrical equipment. Although board designers are trying their best to make this as easy as possible, who hasn't run into a PCB with the wrong foot or a building block of construction (BOM) that missed part? Indeed, it is not easy to get everything right the first time. PCBs and BOMs also need to be cleared of errors. The PCB Assembly Visualizer for Eurocircuits or PCBA Visualizer is an excellent tool for finding such problems before the board is made, saving money and a lot of time.

Holy Trinity PCB, BOM & CPL:

For PCB, board integration requires BOM and component list (CPL). All three are related and must be confirmed concerning others. Combined the holy trinity of the board design:
PCB should have appropriate steps;
The BOM must specify the appropriate sections containing such clues;
CPL should contain the exact locations of these components in the PCB.
PCB Assembly (PCBA) Visualizer provides tools for making these three before the board is ordered.
PCB Assembly Visualizer: Three Steps
It all starts with loading the board design and opening the PCB Visualizer. First, use the tools handled in other topics to ensure that the board can be made.
Upload BOM. The PCBA Visualizer tests comparatively for well-known component sites. Unknown, obsolete, and obscure parts are identified during this step. The problems found here should, of course, be resolved before proceeding.
Adding CPL to the integration allows you to highlight other problems such as incorrect steps, faulty parts, and even non-BOM components.

BOM rules:

It cannot be said often enough: the board cannot be collected when its BOM is incorrect. BOM testing by comparing the well-known suitable components website can only be done if it contains at least one reference designer and Product Component Number (MPN), Provider Component Number (SPN), or a clear description. MPN is selected because it is more accurate, but SPN can sometimes be sufficient. If standard components can be obtained from most providers, e.g., passive or common semiconductors in the industry, a clear definition will suffice.

Get started:

Click the 'PCBA Visualizer' button (note 'A') and click 'Edit meeting data.' PCBA Visualizer accepts Excel and CSV files. Only text files can also be used. After loading, the wizard opens to check that everything is fine and assign columns to the data. When you are done, submit the BOM for analysis.
PCBA Visualizer's BOM Editor
This will open the BOM Editor, which shows the correctly identified parts and those that need to be checked because they do not have a guaranteed track or because they are not found in the database. Do not forget to verify the identified parts to avoid false strikes.

For parts that need extra attention, you can:

Search the site for relevant matches;
select a candidate from the list of suggestions;
add parts to the list;
ignore them;
edit reference designer.
If you have done your homework before starting, this step will probably involve repairing unknown parts by listing them. Eurocircuits and, once certified, will also test such components, will be added to the database that makes it grow.

Put Your Parts:

Placement List (CPL) specifies the exact location of each component on the board. The part is defined by its reference designer, its X and Y links, its rotation, and if there are parts on both sides of the board, the side of the board.

Uploading CPL is similar to BOM, and the wizard will allow you to select the required information first. After sending it, the details will be added to the BOM Editor list. Note that two BOMs are required if parts are placed on both sides of the board. Non-BOM components are now available, as well as components without links.

PCBA Visualizer's CPL Editor:

The next step is to open the CPL Editor to update the components. To do this, click on the 'CPL' tab. The parts are placed almost on the board in the said areas and feet from the BOM. The parts that are fully specified in the BOM and the same for all items (feet, area, pin area 1, etc.) are automatically authorized; some, indicated in orange or red, must be manually authorized.

Troubleshooting CPL Editor lets you:

Move parts (change offset);
Rotate parts;
Remove parts;
Parts of the scale.

Measuring, rotating, and moving everything may be necessary when the integration system used in the CPL file is different from that used by PCBA Visualizer.
Once you are happy with the placement and focus of the feet, you can authorize it (authorization may also be postponed).
You are left with the boss.
CPL Editor is a great tool, but it is not magic or omniscient. Non-database steps cannot be displayed, of course, but as you add to the list while preparing for the BOM, the Eurocircuits team will be notified and may add after confirmation. In that case, you may want to check again later to see if it has been added.

PCB Assembly Visualizer saves time!

Once all components have been approved in the PCB Assembly Visualizer is complete. Now you are sure that your board can be built and integrated into automated production processes without encountering many problems. This will make the process much easier, require less intervention, less money, and, most importantly, less time for you.
