Introducing our special processing, "Super Fine Treatment." We perform Super Fine Treatment to smooth the uneven surfaces of the openings in laser-processed metal masks. By applying this treatment, the release of cream solder improves compared to conventional metal masks. As a result, the blurring of the stencil is reduced, enhancing printability. 【Features】 ■ Smooths the uneven surfaces of the openings in laser-processed metal masks ■ Improves the release of cream solder ■ Reduces stencil blurring and enhances printability *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to our special processing, "Half Etching Treatment." Half Etching Treatment allows for flexible adjustment of the cream solder amount by creating a stepped recess on the squeegee surface at a desired depth when you want to reduce the amount of cream solder for different components within the same plate. Additionally, when you want to prevent solder adhesion due to plate bleeding on areas like gold terminals, half processing on the back of the mask is effective. 【Features】 ■ Position accuracy: ±0.05mm ■ Half etching board thickness accuracy: ±0.01mm ■ Delivery time: Standard processing time + 1 day *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to our special processing, "Titanium Coating Treatment." Titanium Coating Treatment refers to a special metal mask that has undergone special processing on the backside (substrate side) and openings using titanium-based compounds. Compared to standard metal masks or metal masks with fluorine coating, the printability is significantly improved. In particular, it is less likely for paste to remain inside the openings, resulting in better paste release. 【Features】 ■ Special metal mask treated with titanium-based compounds ■ Significantly improved printability compared to standard metal masks ■ Particularly less paste remains inside the openings, leading to better paste release *For more details, please refer to the PDF document or feel free to contact us.

Introducing our "Space-Saving One-Touch Frame." This product reduces storage space by one-third and can be easily secured to the main frame with a single touch. No tools or fixtures are required. The weight remains unchanged from previous models, making it easy to transport and set up the plates. Despite being thin, it maintains the same tension as before. 【Features】 ■ One-third the storage space ■ Secures to the main frame with one touch ■ No tools or fixtures needed ■ Easy to transport and set up plates ■ Maintains the same tension despite being thin *For more details, please refer to the PDF document or feel free to contact us.

This product is a carrier used for soldering after-market components (such as capacitors and heat sinks) using a dip layer after reflow. During soldering, it protects the reflowed substrate with excellent thermal insulation properties, reducing stress on the components. With conventional materials (such as glass epoxy), issues (such as warping) occur after 400 to 600 dips, but our material can be used semi-permanently. 【Features】 ■ Can be used semi-permanently ■ Can be repaired and reused even if damaged ■ Has conductivity ■ Reduces stress on components *For more details, please refer to the PDF document or feel free to contact us.
