摘要:
The invention provides a method to form a pattern (55) of functional material (46) on a substrate (34) for use in electronic devices and components. The method uses a stamp having a relief structure to transfer a mask material (32) to a substrate (34) and form a pattern of open area (42) on the substrate (34). The functional material (46) is applied to the substrate (34) in at least the open area (42). Contact of an adhesive material (52) to an exterior surface (56) opposite the substrate (34) and separation of the adhesive from the substrate forms the pattern (55) of functional material (46) on the substrate (34). The method is- suitable for the fabrication of microcircuitry for electronic devices and components.,

The invention relates to a method and an apparatus for manufacturing an electronic module. The inventive method comprises a substrate (11) which has at least one component (16, 19), particularly a semiconductor chip, arranged on it. In this case, at least one method step involves a film (40) made of plastic material being laminated onto a surface (29) of the substrate (11) and of the at least one component (16, 19), said surface comprising at least one contact area. This method step comprises the following steps: the film (40) to be laminated onto the surface (29) of the substrate (11) and of the at least one component (16, 19), or a film composite (42) comprising the film (40), is arranged in a chamber (31) such that the chamber (31) is split by the film (40) or the film composite (42) into a first chamber section and a second chamber section, which is isolated from the first chamber section so as to be gastight; a higher atmospheric pressure is provided or produced in the first chamber section than in the second chamber section; and contact is made between the surface (29) of the substrate (11) arranged in the second chamber section and the at least one component (16, 19) and the film (40) or the film composite (42), which contact brings about the lamination of the film (40) onto the surface (29).

In order to improve the adhesion of a circuit to a circuit forming board, a separation film (4) comprising a base film and a coating layer formed on the base film is joined to both the sides of the board (1). When a laser beam (5) is applied to form a throughhole (6) in the board (1), a unified portion (7) of the board (1) and the separation film (4) is formed around the throughhole (6). An energy beam is applied to the whole or a part of the surface of a circuit formed at a circuit forming step to transfer a part of the separation film. Thus, a high density board where the circuit strongly adheres to the board can be realized in the manufacturing process of the circuit forming board.

There is described a method of bonding a first article to a second article, by providing a carrier sheet detachably carrying a plurality of closely spaced discrete nodules of adhesive. Applying a contoured surface portion of the first article is applied to said carrier sheet to cause the surface portion of the first article to become substantially covered with nodules of adhesive. The first article is removed from said carrier sheet along with the nodules of adhesive transferred to said first article and applies to a surface portion of the second article to cause the adhesive therebetween to bond the first article to the second article. A material for carrying out the method is also described, being a carrier sheet with adhesive applied thereto in the form of an array of closely spaced discrete nodules.
摘要:
A fine pattern is formed by the following steps. A prescribed mask pattern of an electrically insulative material (3, 5, 8) is formed on an electroconductive surface of a base plate (2) of a printing plate (1), so that the part, other than the mask pattern, of the printing plate becomes an electroconductive printing pattern part . Then, the printing plate (1) is electrolized and the electrodeposition substance (14) is deposited on the electroconductive printing pattern part of the printing plate (1). Then, the deposited substance (14) is transferred onto the surface of a printing object (20) such as a plate of glass or plastic, for forming a pattern thereon. Thereafter, the surface of the printing object (20) is etched with the electrodeposited substance (14) thus transferred as an erosion resistant material.
摘要:
A method of fabricating a toned pattern on an isolated nonabsorbent conductive receiving surface is disclosed wherein a charged electrostatic latent image area is established on an electrostatically imageable surface, and is transferred to the conductive receiving surface across a gap of between about 1 mil and about 20 mils filled with a liquid formed at least partially of a nonpolar insulating solvent in which are suspended charged toner particles. There is also disclosed a method of making a permanent master and a permanent master for an electrostatic image transfer and a method of using such permanent master to electrostatically transfer a electrophotographic developed electrostatic image from the permanent master to a receiving surface are disclosed.
