To provide a terminal mounting structure, the electrical continuation and the joining strength of which are sufficiently high although the structure is simple, further the reliability of which is high even when it is used over a long period of time and to provide a terminal mounting method therefor. A terminal (3) is connected and continued to a conductor (2) such as a heating wire provided on a substrate (1). Terminal (3) includes: a fixing portion (31); elastic portions (32) extending from fixing portion (31); and a substrate contact portion (33) provided in elastic portion (32) so that substrate contact portion (33) can be protruded with respect to substrate (1), and electrically connected to conductor (2). Each fixing portion (31) is made to adhere to substrate (1) by a joining means such as a double-sided adhesive tape (4). Substrate contact portion (33) of terminal (3) is made to adhere to substrate (1) by adhesive (5) under the condition that substrate contact portion (33) comes into contact with conductor (2) by a repulsive force generated by an elastic displacement of elastic portion (32).

A method for connecting FPC to a second circuit board, comprising the steps of (i) preparing a flexible printed circuit board (FPC) and a second circuit board, (ii) disposing the connection parts of the FPC to face the connection parts of the second circuit board such that a thermosetting adhesive film is present between the connection parts of the FPC and the connection parts of the second circuit board, and (iii) applying heat and pressure sufficiently high to thoroughly push away the adhesive film for establishing electrical contact and allow for curing of the adhesive, wherein the ratio of conductor width (L)/conductor-to-conductor distance (S) in the conductor wiring end parts constituting the connection parts of FPC is 0.5 or less and the thermosetting adhesive film is adjusted to have a viscosity of 500 to 20,000 Pa·s at 200° C.
摘要:
A composition for preparing a reactive hot melt composition comprises (a) a thermoplastic polymer which comprises a polyolefin having an epoxy group, and (b) a radiation polymerizable component containing (b-1) an aliphatic alkyl (meth)acrylate and (b-2) an acrylic compound having a functional group reactive with an epoxy group. A reactive hot melt composition is obtained by polymerizing this composition so as to polymerize the radiation polymerizable component.The reactive hot melt composition which can be easily hot melt coated, crosslinked quickly in the absence of radiation or moisture after bonding adherends, does not form moisture during crosslinking, and has high flowability during hot melting.
