Various technologies! An explanation of "wall treatment," including the basic reasons and types that require processing.
Wall surface treatment, as the name suggests, refers to "treating" the "wall surface." Here, the wall surface of the metal mask refers to the "opening wall surface." Applying physical or chemical treatment to the opening wall surface is referred to as treatment, and collectively, it is called "wall surface treatment." In this column, we introduce various aspects of "wall surface treatment," including types and methods. Please take a moment to read it. 【Contents】 ■ What is wall surface treatment? ■ Why is wall surface treatment necessary? ■ Basic reasons why wall surface treatment is needed ■ Types of wall surface treatment ■ Methods of removing (melting) ■ Methods of adding *For detailed content of the column, you can view it through the related links.

![[Column] A Metal Mask Manufacturer Investigates Removable Metal Masks](https://image.mono.ipros.com/public/product/image/724/2000734907/IPROS25350092474853769639.png?w=280&h=280)
In addition to the detachable lineup, a space-saving metal mask with an aluminum frame type is also included!
The non-removable metal mask is made by adhering a SUS plate with holes created by laser processing to an aluminum frame covered with a resin mesh called "sha" using a special adhesive. The "removable metal mask" refers to a type that uses a SUS plate with holes created by the aforementioned laser processing, which is set into a dedicated frame. Our removable metal mask "Shippu" allows for the storage of only the SUS plate, significantly reducing the storage space required for metal masks.

![[Column] Design of Metal Mask Openings and Plate Thickness](https://image.mono.ipros.com/public/product/image/dc3/2000735623/IPROS80252092502474866722.png?w=280&h=280)
The selection of thickness is important for the "solder release property," which determines whether the cream solder can be removed cleanly!
This column explains "Metal Mask Opening Design and Thickness." The metal mask data, which serves as the opening data for the metal mask, is generally created to be the same size as the substrate pads. However, especially recently, the difficulty of implementation has increased, and it seems that things are not going as smoothly as expected. Therefore, based on the metal mask data provided by our customers, we will design the metal mask openings to achieve a printing state that is assumed to have no issues with component mounting quality.

![[Column] Behind the Development of CoCo Processing](https://image.mono.ipros.com/public/product/image/1b7/2000746503/IPROS67051158141747232253.png?w=280&h=280)
This is a story related to the development of the "CoCo process," which involves bringing the metal mask opening closer to the pads on the substrate.
This column explains the "development story of CoCo processing." "CoCo processing" can be described in one word as a process that absorbs the height differences of the silk printed characters on the circuit board and brings the metal mask openings closer to the pads on the circuit board. By absorbing the height differences of the silk during squeegeeing and bringing the openings closer to the circuit board pads, it is possible to suppress smudging caused by gaps between the circuit board and the metal mask, as well as excessive solder due to the height of the silk, thereby improving the stability of the printing process. [Contents] ■ What is "CoCo processing" in the first place? ■ Background of CoCo processing development ■ How the specifications for CoCo processing were determined ■ The subsequent development of CoCo processing ■ Origin of the name "CoCo processing" *For detailed content of the column, please refer to the related links.

Quality improvement through "mechanisms" and "systematization" instead of "strict inspections"! Introducing our company's initiatives.
The efforts to create "high-quality products" are something that those reading this column are likely to think about regularly. Of course, our company is no different, and we are engaged in production daily, considering the specifications or requests from our customers to drill holes in stainless steel according to their designs. In the production of metal masks, there are many processes where human involvement is necessary, such as arrangement, editing, and combination, making it important to implement measures to prevent human error. Our factory's approach focuses on quality improvement through "systems" and "mechanisms" rather than just "strict inspections." *For more details on the column, you can view it through the related links.
