Method for manufacturing a module and an optical module
A method for manufacturing a module including N layers of stacked resin is provided, wherein N is a natural number of two or more. In the method, resin of a first layer is cured to a degree that does not fully harden the resin of the first layer. Resin of a Mth layer is stacked on resin of a (M1)th layer, wherein M is a natural number of two or more and less than N. The resin of the Mth layer is cured to a degree that does not fully harden the resin of the Mth layer. Stacking the resin of the Mth layer and curing the resin of the Mth layer are repeated. Then, resin of Nth layer is stacked, and all of the N layers of stacked resin are fully hardened.

ANISOTROPIC ELECTRICALLY CONDUCTIVE FILM, METHOD FOR PRODUCING SAME, AND CONNECTION STRUCTURAL BODY
The present invention provides an anisotropic electrically conductive film with a structure, in which electrically conductive particles are disposed at lattice points of a planar lattice pattern in an electrically insulating adhesive base layer. A proportion of the lattice points, at which no electrically conductive particle is disposed, with respect to all the lattice points of the planar lattice pattern assumed as a reference region, is less than 20%. A proportion of the lattice points, at which plural electrically conductive particles are disposed in an aggregated state, with respect to all the lattice points of the planar lattice pattern, is not greater than 15%. A sum of omission of the electrically conductive particle and an aggregation of the electrically conductive particles is less than 25%.
Method for producing a connecting medium on an assembly partner, method for producing a material-fit connection between an assembly partner and a metal layer, and a system for carrying out the methods
A method for producing a layer including a connecting medium on an assembly partner is provided. The method includes providing a carrier on which the connecting medium is applied. The connecting medium contains a metal in the form of a multiplicity of metal particles. The assembly partner is placed on the connecting medium located on the carrier and pressed onto the connecting medium located on the carrier, so that a layer of the connecting medium adheres to the assembly partner. The assembly partner together with the layer adhering thereto is removed from the carrier. By means of a gas flow, edges of the layer, at which the latter extends laterally beyond the assembly partner, are removed so that a layer residue of the layer remains adhering to the assembly partner.
