摘要:
To ensure required adhesion even when a pipe of a piping module collides with a temporary material during transport and achieve easier dismantling, the following measure is taken: the temporary material is fixed on a support rack to prevent the piping module placed on the support rack from largely displaced during conveyance and after the conveyance of the piping module, the temporary material is removed from the support rack. In this method, the following measures are taken: at the step of fixing the temporary material to the support rack, the temporary material is bonded to the support rack with the piping module set therein using adhesive; and at the step of removing the temporary material from the support rack after the conveyance of the piping module, the temporary material bonded to the support rack with the adhesive is peeled off from the support rack with heat applied thereto.

A temporary part is fixed to a base by using an adhesive layer to which fillers are mixed at a predetermined density. When the temporary part is heated, heat is applied to the fillers and the adhesive layer. At a temperature equal to or higher than the glass-transition temperature of the adhesive agent, the heated adhesive layer is thermally contracted so as to release remaining stress, and on the other hand, the heated fillers are thermally expanded. In this manner, the peel-off strength between the adhesive layer and the base (or the temporary part) is reduced, and the disassembly is facilitated.

A flow sensor includes an auxiliary channel having an opening into which a fluid to be measured is taken; a sensor element that measures the flow of the fluid to be measured; a housing that accommodates electronic parts; and a resin cover. The flow sensor is configured such that junctions of the housing and the cover are formed in locations where first target weld portions, which are formed so that the circuit chamber is surrounded, face each other and second target weld portions, which are disposed for additional reinforcement of the joints, face each other on a bonding face of the housing and a bonding face of the cover with a step being provided. The positioning of the housing and the cover is determined, and the first target weld portions are welded to each other and second target weld portions are welded to each other by way of laser radiation.

There is a method of manufacturing an RFID, in which a semiconductor chip with a memory is bonded to an antenna, so that the information recorded in the memory can be transmitted through the antenna. In the RFID, a PET film, a PEN film, or a sheet of paper is used as the base material of the antenna. The method includes: aligning the semiconductor chip with gold bumps relative to the antenna, in which a metal foil formed of an aluminum or an aluminum alloy is adhered to the base material, including a polyethylene terephthalate or a polyethylene naphthalate; pressing the semiconductor chip to the antenna; and applying ultrasonic waves under an ambient temperature lower than the glass transition temperature of the polyethylene terephthalate or the polyethylene naphthalate, to thereby bond the gold bumps and the metal foil. Thus, the method suppresses the deformation of the antenna.

A semiconductor device includes a semiconductor chip, a first substrate, and a second substrate. The first substrate includes a plurality of wires and a plurality of first electrodes, each first electrode being connected with each wire. The second substrate includes the semiconductor chip that is mounted thereon, and a plurality of second electrodes with, each second electrode being connected with the each first electrode of the first substrate. The widths of the wires of the first substrate are different depending on the lengths of the wires. By changing the widths of the wires depending on their lengths, it is possible to reduce variation in stiffness of the electrodes and vicinities of electrodes, whereby variation in ultrasonic bonding strength can be reduced.

The present invention aims to improve the durability of an RFID chip inlet. A module including an RFID chip amounted to an antenna is covered with polyimide film with an adhesive layer to make up an RFID inlet. The outer surface of the RFID inlet is then covered with the surface processed to increase surface lubricity of a base part. When the RFID inlet is for use in a rubber product, it is mounted to a rubber base of the rubber product, the exposed surface of the RFID inlet is covered with an unvulcanized rubber, and the unvulcanized rubber is then pressed and heated causing the RFID inlet to be embedded in the rubber base.
