  • Publication number: 20070006776
    Abstract: The coating liquid for forming porous silica according to the present invention is characterized by preferably containing a partial hydrolysis-condensation product of an alkoxysilane compound, a surfactant and an organic ampholyte, and by having a metal content of not more than 50 ppb. Conventional coating liquids for forming porous silica have such a problem that porous silica films formed therefrom may have poor regularity in micropore alignment when the shelf life of the coating liquids are long. On the contrary, the coating liquid for forming porous silica of the present invention is excellent in self-life stability. Namely, the quality of porous silica formed therefrom is hardly affected by the length of self-life period of the coating liquid.

The edge of the solder resist layer is formed almost in parallel or almost at right angles to the moving direction of the squeegee used in the application of the solder resist. The solder resist layer can be formed by the use of a screen mask for solder resist coating in which the edge of the screen that is unmasked to apply the solder resist is formed almost in parallel or almost at right angles to the moving direction of the squeegee used in the application of the solder resist. According to the present invention, the fraction defective of the solder resist coating can be decreased.
