What Is SMT in PCB Assembly?
Instead of drilling holes and inserting leads like traditional through‑hole (THT) assembly, SMT places tiny surface-mount devices (SMDs) directly onto the pads on the PCB surface and solders them in place, usually by automated SMT assembly lines and reflow soldering.
Because SMT components are much smaller and can be mounted on both sides of the PCB, SMT PCB assembly enables:
- Higher component density – more functions on a smaller board
- Smaller and lighter products – ideal for modern consumer and industrial electronics
- Better electrical performance – shorter signal paths, improved high‑frequency behavior
- More automation and consistency – stable quality and lower labor cost in mass production
As an SMT assembly manufacturer in Shenzhen, China, PCBAgroup use advanced Panasonic CM602/NPM SMT lines to provide high‑precision SMT PCB assembly for both prototypes and mass production.

What Files Do We Need for SMT Assembly Quotation?
To provide you with an accurate and fast SMT assembly quotation, we need some basic PCB design and assembly-related files. These documents allow our engineers to understand your SMT PCB assembly requirements, calculate SMT assembly cost, and check manufacturability (DFM) before production.
Even if you don’t have everything ready, you can still send us what you have, and our engineering team will help you sort it out.
Minimum files required for SMT PCB assembly quote
- Gerber files or ODB++
- BOM (Bill of Materials)
- Pick & Place / Centroid file
- Assembly drawing / PCBA drawing
Recommended additional data for smoother SMT production
- Schematic (PDF or source CAD format)
- 3D files (STEP, IGES)
- Panelization drawing (if applicable)
- Testing requirements and procedures
- Special process requirements
If you are not sure whether your files meet the requirements, just send us your Gerber and BOM first.
