example 1

[0079] Porous drawn PTFE (trade name HP010-60, manufactured by SMMITOMO ELECTRIC FINEPOLYMER, INC) with a pore size of 0.1 μm, a porosity (ASTM D-792) of about 50%, and a film thickness of 60 μm was smoothed and set on a glass plate , and secure it with plastic straps around its edges to prevent movement. On the porous drawn PTFE, instant adhesive (trade name Aron Alpha, manufactured by TOAGOSEI Co., Ltd.) was thinly applied. Then, on the instant adhesive layer, a mask made of stainless steel having a slit of 100 μm in width and 5 mm in length opened thereon was provided to have a thickness of 0.05 mm. The membrane was left standing overnight to allow the instant adhesive to dry sufficiently to secure the stainless steel mask to the porous drawn PTFE.

[0080] From above a mask made of stainless steel, the sandblasting process is performed by compressed air using aluminum abrasive grains with an average grain diameter of approximately 5 μm. By transmitted light detection, it...

[0084] A porous drawn PTFE membrane with a pore size of 5 μm, a porosity of about 80%, and a membrane thickness of 100 μm (trade name WP500-100, manufactured by SMMITOMO ELECTRIC FINE POLYMER, INC.) was smoothed and set on a glass plate, and fixed with adhesive tape in case of movement. An instant adhesive (trade name Aron Alpha, manufactured by TOAGOSEI Co,. Ltd.) was thinly applied on the porous drawn PTFE. Then, on the instant adhesive layer, a mask made of stainless steel in which a slit of 100 μm in width and 5 mm in length was opened was provided to have a thickness of 0.05 mm. The membrane was left standing overnight to allow the instant adhesive to dry sufficiently to secure the stainless steel mask to the porous drawn PTFE.

Abstract

An object of the present invention is to provide a method for manufacturing a porous material in which complicated and fine through portions, recessed portions, and the like have been patterned. It is to provide a patterned porous molded product or nonwoven fabric, in which a plated layer has been selectively formed on the surfaces of the through portions and the recessed portions. With the invention, a mask having through portions in a pattern is placed on at least one side of the porous molded product or the nonwoven fabric. A fluid or a fluid containing abrasive grains is sprayed from above the mask, thereby to form through portions or recessed portions, or both of them, to which the opening shape of each through portion of the mask has been transferred, in the porous molded product orthe nonwoven fabric. The invention provides a porous molded product or a nonwoven fabric in which a plated layer has been selectively formed on the surfaces of the through portions or the recessed portions, or both of these, an electric circuit component, or the like.

Description

technical field [0001] The present invention relates to a method of manufacturing a porous molded product or nonwoven fabric in which penetrating portions such as penetrating holes and penetrating grooves and recessed portions such as grooves have been patterned. Also, the present invention relates to a manufacturing method of a porous molded product or a nonwoven fabric, wherein a plating layer is selectively formed on the surface of a recessed portion, a penetrating portion, or both by patterning. Furthermore, the invention also relates to circuit elements made of porous molded products or nonwovens with a patterned coating. According to the present invention, the porous molded product or the nonwoven fabric having the patterned plating layer can be preferably applied to technical fields such as semiconductor device mounting members, electrical reliability inspection members, and the like. Background technique [0002] Substrates for fabricating electronic components may ...
