    • A screen mask includes a screen mesh with a tensioning force of 196 to 392 N/mm; a tension mesh with a tensioning force of 49 to 98 N/mm; a resin plate (fixing part) arranged so as to surround the outer periphery of the screen mesh for fixing a part of the tension mesh with a tensioning force of 392 to 980 N/mm; and a screen frame. A length Ls of the screen mesh in a first direction intersecting a direction in which a squeegee squeegees on the screen mesh when performing a screen printing is 0.6 to 0.9 times a length Lt of the tension mesh in the first direction, a length Lk of the resin plate, the length Ls, and the length Lt in the first direction satisfy a relationship Lk=a(Lt+Ls)/2, where “a” is a coefficient in a range of 0.5 to 1.2.
    • 屏幕掩模包括具有196至392N / mm的张力的筛网; 拉伸力为49〜98N / mm的张力网; 布置成围绕所述筛网的外周的树脂板(固定部),用于以392〜980N / mm的张力固定所述张力网的一部分; 和屏幕框架。 在进行丝网印刷时,与筛网上的刮板刮擦方向相交的第一方向的筛网长度Ls为第一方向上的张力网的长度Lt的0.6〜0.9倍, 树脂板,长度Ls和第一方向上的长度Lt满足关系Lk = a(Lt + Ls)/ 2,其中“a”是0.5至1.2范围内的系数。

    • The invention provides a technique which can improve a printing precision of a screen printing. A fixing mechanism for fixing a screen mask of a printer to a mask holder is structured such as to include a first fixing mechanism fixing sides of four sides of a frame existing in an outer peripheral edge of the screen mask arranged along an arrow corresponding to a sliding direction of a squeegee, and the mask holder, and a second fixing mechanism fixing a side of four sides of the frame arranged along a direction intersecting the arrow and in an opposite direction to the arrow as seen from the slide starting position, and the mask holder.
