Tolerance Overview

Factors Affecting Etching Tolerance:
●Metal material
●Plate thickness
●Material dimensions
●Pattern layout to be etched

(Unit: mm)

Thickness	Tolerance	Min. Hole
0.1	±0.03	0.25
0.2	±0.03-0.05	0.3
0.3	±0.05~0.08	0.5
0.4	±0.08~0.15	0.6
0.5	±0.15~0.20	0.8
0.5~1.0	Final specifications to be agreed upon according to the actual design and process feasibility.

About Break-off Point

What is a break‑off point? In most cases, precision parts are bridged to the sheet during etching to complete processing.

External Tab

External Tab: the most common type, leaving a small nib at the pre-break point, which can be reduced through post-grinding.

Internal Tab

Internal Tab: similar in function, but recessed within the part to preserve exterior aesthetics and prevent interference with surrounding assemblies.

If my part cannot have tabs, what are my options?

Tab‑less processing is available for SUS at 0.1–0.2 mm, preserving surface smoothness; however, being single‑sided etching, tolerances are looser. For more details on tabs, please get in touch with us.

We’ll safeguard your project end‑to‑end.
