JLCPCB PCBA Order File Replacement Service Guide

When you need to update your Gerber, BOM, or CPL files after placing a PCBA order, JLCPCB provides a dedicated File Replacement Service to help you make corrections easily. This process ensures production accuracy and avoids potential assembly errors.

How It Works

1. Request File Replacement

If you find any errors or updates needed in your submitted files, please contact our customer service team.

Upon receiving your request, our support team will manually activate the replacement channel in the background.

2. Order Cancellation & Refund

To ensure data accuracy and avoid file mismatches, your original order must be cancelled once a file replacement request is confirmed. A full refund will then be issued automatically.

Note: The cancellation and refund are standard procedures — not additional charges

3. Upload New Files

After the replacement channel is activated, you will see a “Replace File” button on your original order page. Please click it to upload all your updated files.

4. Repricing & Payment

Because the files have changed, the system will automatically recalculate the total cost based on your new files. Please review the new quotation and complete the payment to confirm your updated order.

In short: Replacing files = cancel old order + full refund + create new order with updated files and new price.
This ensures the most accurate and reliable PCBA manufacturing results.

Frequently Asked Questions

Q1: Why is a full refund processed first?

This ensures complete financial transparency and data accuracy. When you modify your files — especially the BOM — it can directly change component prices, assembly fees, and related costs.

By processing a full refund first, the system cleanly closes the original order and then generates a new quotation based entirely on your updated files. This approach eliminates the need for complex partial refunds or balance adjustments, ensuring your payment always matches the exact production requirements of your final design.

Q2: What are the advantages of using the “File Replacement” service instead of simply “Cancel and Reorder”?

The File Replacement service is designed to be more efficient, accurate, and secure than a standard cancel-and-reorder process.

Key Benefits:

• Inventory Protection: To prevent component shortages or price fluctuations, the system reserves the components from your original order for 48 hours. This ensures that your revised order can still use the same parts whenever possible.
• Simplified Workflow: No need to re-enter order details — simply replace your files with one click.
