How much does PCB assembly cost?

The total cost of PCB assembly typically includes setup fees, stencil costs, assembly labor, and components. Pricing is calculated in real time through the online quote system.

How do I prepare a BOM file for PCB assembly?

A BOM (Bill of Materials) for PCB assembly should include component values, reference designators, package types, and manufacturer part numbers. Standard file formats such as CSV, XLS, or XLSX are recommended.

How can panelization reduce PCB assembly costs?

Panelization reduces PCB assembly costs by grouping multiple boards into a single panel for simultaneous processing. This improves manufacturing efficiency and lowers the cost per unit. Panelization is generally recommended for production quantities above 50 pieces.

How long does PCB assembly take?

Approximately 90% of PCB assembly orders are completed within 24 hours, and most within 48 hours, making it suitable for rapid prototyping and urgent production.

What if I cannot find a component in the JLCPCB Parts Library?

If a component is not available in the parts library, multiple sourcing options are available, including in-stock components, global sourcing through distributors, pre-order parts, consigned components provided by customers, and new part requests. This ensures flexibility in sourcing all required components for PCB assembly.
