EMI — Etched EMI/RFI Shielding Cans: Vents, Fold Lines and Logos in a Single Pass
The shield is usually the last part designed and the first part to hold up a build. The board respins, components move, the vent pattern shifts — and the can no longer fits. Etched shields don't have that problem, because the shield is a drawing before it's anything else. Shielding is one of the four product lines Metching is built around. From our Dongguan plant, etching electronics and semiconductor components since 2005, we make shielding cans, covers, lids and board-level

Etched Encoder Discs: The Slot Pattern Lives in the Artwork
An encoder disc has one job: put the same slot in the same place, every revolution, for years. Stamping gets there with a precision die that wears. Laser cutting gets there with taper and dross on the slot walls. Etching photographs your CAD file into the metal — so disc one and disc ten thousand carry the identical pattern. Encoder discs are where Metching started in electronics etching. We're a Dongguan plant producing etched components since 2005, specialising in parts for

Etched Lead Frames: First Frames and Fast Revisions, No Stamping Die
A package drawing lands on our desk. The silicon schedule is set, qualification has a date, and nobody has budgeted for a progressive die yet. That gap — between a finished drawing and a justified die — is where etched lead frames earn their keep. Metching is a Dongguan etching plant working on electronics and semiconductor components since 2005. Lead frames are one of our core lines. We etch them in copper and stainless steel from 0.05 to 2.5 mm thick, straight off the packa
