JLCPCB Advanced Stencil-Nano-coating

Nano-coated SMT stencils are designed to improve solder paste release, especially for fine-pitch and dense PCB designs.

By applying a nano-scale coating to the stencil surface and aperture walls, the stencil becomes more hydrophobic, which helps reduce solder paste adhesion and residue during printing.

🔍 What problems can nano-coated stencils help solve?

Poor paste release on fine-pitch components

Inconsistent deposits on small apertures

Paste sticking to the bottom of the stencil

Frequent stencil cleaning during assembly

⚙️ Typical use cases

Nano-coated stencils are commonly used for:

Fine-pitch ICs (QFN, LQFP, small-pitch connectors)

High-density PCBs

Boards with mixed aperture sizes

Projects requiring more stable printing consistency

🧠 Things to keep in mind

Nano coating does not replace proper aperture design

Paste type and printing parameters still matter

It’s especially effective when combined with electropolished apertures
