Printing device, production unit, and production method of electronic parts

A production method of electronic parts, including the steps of:

• overlaying a perforated plate having a through hole pattern penetrating the upper surface and the lower surface on a work piece positioned in a horizontal position, and allowing the lower surface of said perforated plate to approach said work piece;
• pressing and filling a plastic material into said work piece by pressurefeeding said plastic material into the through hole pattern of said perforated plate;
• and
• generating a differential pressure with said perforated plate spaced apart so that the air pressure of the upper surface side of said perforated plate becomes higher than that of said lower surface side.

A production method of electronic parts, including the steps of:

• positioning a work piece in a horizontal position on an alignment table adjustable in height;
• supporting in a horizontal position a perforated plate having a through hole pattern penetrating the upper surface and the lower surface above said work piece positioned on said alignment table;
• allowing the lower surface of said perforated plate to approach said work piece by performing a height adjustment of said alignment table;
• pressing and filling said plastic material into said work piece by pressure feeding said plastic material into the through hole pattern of said perforated plate;
• and
• generating a differential pressure with said perforated plate spaced apart so that the air pressure of the lower surface side of said perforated plate becomes higher than that of said upper surface side.
