Heat resistant insulative membrane and insulative method

Abstract

The objective is to enable easy and economic insulation treatment by mounting an insulating film with functionality such as heat resistance in insulating a surface of an object to be insulated. In mounting the heat-resistant insulating film 21 on a base plate 30 with electronic components 31 to 38 loaded, a shape pattern 21a corresponding to a shape of the surface to be insulated including a concave part and a convex part is formed by a three-dimensional molding on the heat-resistant insulating film 21, and the electronic components 31 to 38 or a circuit board 30 is covered with the heat-resistant insulating film 21.

Description

technical field [0001] The present invention relates to a heat-resistant insulating film and an insulating method using the film. Background technique [0002] With the integration and high functionality of electronic parts, people are paying more and more attention to the importance of the function of the insulating layer formed on the electronic parts or on the substrate carrying the electronic parts. In fact, in the prior art, polyimide-based resins and the like having heat resistance, high mechanical strength, and dimensional stability have been used instead of thermosetting epoxy resins and the like used as insulating layers. Sexual resin. In general, an insulating layer based on such a polyimide-based resin or the like can be formed by the following procedure. That is, the precursor solution is coated on the surface to be insulated with a predetermined thickness, and then the imide conversion of dehydration and closed-loop is carried out by drying and heating, thereb...

Problems solved by technology

However, generally speaking, because films such as polyimide resins with high functionality have relatively poor shape followability, good performance cannot be achieved when concave or convex portions are included on the surface to be insulated (the surface to be insulated). installation, resulting in poor stability after installation

Furthermore, when the shape of the surface to be insulated is relatively complex, it is necessary to use multiple insulating films, thus resulting in a complicated manufacturing process.
