My PCBA needed a little extra customization.JLCPCB made it happen

When designing a PCB, sometimes the standard assembly process is just not enough.

Maybe your LED needs an extra spacer to sit at the perfect height.
Maybe your board needs a few wires soldered directly onto it.
Maybe a component comes with a positioning pin that gets in the way, and you need it removed before assembly.

These small details can become challenging during production.

Luckily, I found a really useful feature on JLCPCB: PCBA Remark.

During the PCBA order setup, simply go to:

PCBA Parameters → PCBA Remark → Yes

Then leave a detailed note describing your special requirements.

For example:

• Add a spacer for LED1 (Part Number: ). Please install spacer model #123 to keep the LED at the required height.
• Solder a wire cable to connector J2 (Part Number:) according to the attached instructions.
• Remove the positioning pins from component U3 (Part Number: ) before assembly, then proceed with soldering.
• Perform manual soldering for component R5 (Part Number:) because it requires a special assembly method.

After submitting the order, engineers will review your request, evaluate the manufacturing process, calculate any additional cost if needed, and send the details to you by email.

No complicated communication. Just leave your requirements clearly, and the engineering team will help make it happen.

As a hardware maker, I really appreciate this kind of flexibility. Not every project is a simple “upload files → assemble → done” process. Sometimes a product needs those small extra touches to become the final version you imagined.

A simple remark can make a big difference.
