Frequently Asked Questions About SMT PCB Assembly

Common questions about surface mount technology,, assembly processes, capabilities, and services.

What is the difference between SMT and SMD?

SMT (Surface Mount Technology) refers to the assembly process and method of mounting components onto PCBs. SMD (Surface Mount Device) refers to the actual components themselves that are designed for surface mounting. In essence, SMT is the process, while SMD are the parts used in that process.

What is the minimum order quantity (MOQ) for SMT assembly?

There is no single fixed MOQ for SMT assembly; it depends entirely on the assembler and whether you’re doing prototypes or production.

How long does SMT assembly take?

SMT assembly itself typically takes from 1–5 working days for prototypes and small batches, and up to 10–20 working days or more for larger production runs.

Can you mix SMT and through-hole components on the same board?

Yes, SMT and through-hole components can be used on the same PCB; this is called mixed or mixed-technology assembly.

What file formats do you need for SMT assembly?

For SMT assembly, fabricators almost always need Gerber/ODB++ board data, a BOM (usually CSV/XLSX), and a pick‑and‑place/centroid file (CSV/TXT).

Is lead-free (RoHS compliant) assembly available?

Yes, lead‑free, RoHS‑compliant SMT assembly is widely available and is now the default offering at most professional PCB assemblers.

Can you handle double-sided SMT assembly?

Yes, double‑sided SMT assembly (components on both top and bottom of the PCB) is standard practice at most modern assembly houses.
