Screen printing mask and manufacturing method thereof
A screen printing mask (10) includes a main mesh (20), a main resin layer (30), and an additional net-like section (50A). The main resin layer (30) is provided on the main mesh (20) and has a through-hole (35). The additional net-like section (50A) may have a first additional layer (50Aa) and a second additional layer (50Ab). The first additional layer (50Aa) is provided on the main mesh (20), together with the main resin layer (30) by curing, through absorption of light, photocurable resin applied onto the main mesh (20). The second additional layer (50Ab) is provided on the first additional layer (50Aa) by curing, through absorption of light, a photocurable resin applied onto the first additional layer (50Aa). The additional net-like section (50A) has a greater thickness or depth than the main resin layer (30) so that a thicker portion is printed on a substrate in accordance therewith.
Printing screen
A printing screen includes a screen-shaped fabric layer with fabric threads being angled relative to one another to form a carrier layer. An imaged stencil layer is connected to the fabric layer and provided with passages. A respective passage forms a continuous channel and has an opening that is smaller on a printing material side of the printing screen than on a squeegee side of the printing screen. Such a printing screen has sufficient stability and advantageously allows the finest lines and dots to be printed. A method for imaging such a printing screen is also provided.
