SMT Printing: The Critical First Step in PCB Assembly

SMT printing (solder paste printing) is the process of depositing solder paste onto PCB pads through a stencil. It is the most influential step for final assembly quality. SMTFullLine provides reliable stencil printers for every level of automation.

How SMT Printing Works

1. Stencil alignment – The stencil is aligned with the PCB using fiducial marks.

2. Paste application – Solder paste is spread across the stencil using a squeegee.

3. Snap‑off – The stencil separates, leaving paste on the pads.

Types of SMT Printers

• Manual printer – Operator aligns and moves squeegee. Low cost, for prototyping.

• Semi‑automatic – Mechanical squeegee movement; operator loads boards.

• Fully automatic – Vision alignment, automated paste dispensing, under‑stencil cleaning.
