How Does a High Precision Screen Printing Machine Work?

あ high precision screen printing machine uses a mesh stencil to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil.

The Process Explained

1. 準備: The design is etched onto a stencil または silk screen.
2. Alignment: The substrate, like a PCB, is precisely aligned under the stencil.
3. 応用: Solder paste or ink is applied over the stencil.
4. Transfer: A squeegee moves across the stencil, pushing the material through the open areas.
5. 結果: The desired pattern is left on the substrate.

This method allows for high precision printing, essential for small components and complex circuits.
