Sierra Circuits’ BOM Compare Tool is the first web application that enables you to compare two PCB BOMs and identify differences between them within no time. You just have to upload bills of materials and map the columns, the tool quickly displays newly added, deleted, and modified data.
PCB designs generally undergo multiple iterations during the design phase. Hence, you have to submit a new or revised bill of materials to your manufacturer. Before this, you need to compare and validate the BOM data to avoid miscommunication and expensive delays.
Manually comparing the details such as component names, quantities, and MPNs is a time-consuming and cumbersome process.
To help you overcome this challenge, Sierra Circuits has introduced the BOM Compare Tool. This web app can quickly identify the changes in the BOM, and validate the data. You can share the updated BOM with the quoting team to proceed with the ordering process.
Upload your first BOM on the left as shown above and the second one on the right. The color codes on the extreme right differentiate among newly added, deleted, and modified data. Newly added in green, deleted in red, and modified in blue.
After uploading the bill of materials files, click on Proceed.
The tool automatically maps item number, MPN, quantity, and reference designator fields. If you’d like to compare more fields you can add them by clicking on the “+” button. Apart from the default parameters, you can include up to 6 fields.
To delete the added columns, you can click on the respective “X” buttons.
Hit Compare to view the results.
The comparison results will have 3 sections:
You can also download the output data by clicking on the Export to Excel button at the top right corner.
