摘要:
The present invention aims at providing an electronic component mounting apparatus and an electronic component mounting method that perform automated setting of a thickness of a paste film.The electronic component mounting apparatus of the present invention has a paste transfer unit 10 that horizontally, relatively moves a squeegee 11b and a transfer surface 13 with respect to each other, thereby spreading, over the transfer surface 13, a paste film 3 whose thickness is equivalent to the height of a squeegee gap “c” formed from clearance between the squeegee 11b and the transfer surface 13; a storage unit 18 that stores a database defining correlation among bump heights, paste types, and squeegee-gap heights; a computing unit 20 that derives, from the database, a squeegee-gap height G21 in correspondence with a height H1 of a bump of an electronic component to be mounted and a type P2 of paste to be transferred; and a vertical movement mechanism 16b that adjusts the height of the squeegee gap “c” formed from clearance between the squeegee 11b and the transfer surface 13 to a derived squeegee-gap height.

摘要:
In a mounting system having a height measuring instrument for measuring the height of solder paste printed on the electrodes and an electronic component placing apparatus, whether the height of solder paste is right or wrong is determined based on the measurement result of measuring the height of solder paste printed on the electrode. Further, whether or not the transfer of solder paste to the solder bump is required based on the determination result, and if it is determined that the transfer is required, the paste is transferred to an electronic component held in a mounting head. Thereby, the mounting quality can be assured by adding adequately an amount of solder in treating the board causing a shortage of the solder amount due to printing failure.

First components and second components in which bumps are formed on the lower surface thereof and laminate structures are formed by mounting them to stack with each other on a circuit board 13 are picked up from a component supply unit 1 using a placement head 16, and by lifting and lowering the placement head 16 holding the first components and the second components relative to a paste transfer device 5 supplying a flux 10 in the manner such as coating films having two types of different thicknesses, the flux 10 is supplied to the bumps of the plurality of components in a bundle using a transfer coating method. With such a configuration, it is possible to efficiently perform a component mounting with a satisfactory adhesiveness by ensuring an optimal amount of application quantity of a paste.

To provide an electronic component placing apparatus and an electronic component mounting method that can prevent a cold joint from occurring when an electronic component likely to cause warp deformation is mounted by means of soldering. In the electronic component placing apparatus for placing the electronic component 16 with a plurality of solder bumps 16a formed on a lower surface on a board, a film 7a having a film thickness distribution for transferring a desired transfer amount of solder paste according to a state of warp deformation to each of the plurality of solder bumps is formed in a paste transfer unit 24, based on the component warp information indicating the state of warp deformation in a reflow process of the electronic component. Thereby, it is possible to prevent a cold joint from occurring when the electronic component likely to cause warp deformation is mounted by means of soldering by additionally supplying a just enough amount of solder to each solder bump 16a.

A shift controller controls a transmission for a hybrid vehicle in which: an engine and a motor are connected together via a clutch; and the transmission is placed between the motor and driving wheels. The shift controller has: a first shift controlling unit which performs shift control on a basis of at least one of transmission efficiency of the transmission and power generation efficiency of the motor in a case where regeneration is performed with the clutch disengaged during deceleration of the hybrid vehicle; and a second shift controlling unit which performs shift control to make a transmission gear ratio of the transmission smaller than in the shift control performed by the first shift controlling unit in a case where the regeneration is performed with the clutch engaged during the deceleration of the hybrid vehicle.

A temperature sensor includes: a temperature-sensing element comprising a temperature-sensing portion and an element electrode wire connected to the temperature-sensing portion; a sheath member comprising a sheath tube and a sheath core wire extending from the sheath tube, the sheath core wire being joined to the element electrode wire to form a joint portion; an enclosing member comprising a closed-bottomed tube having a bottom portion at one end, and enclosing at least the temperature-sensing element and the joint portion; and a holding material filling at least a portion of a space enclosed by the enclosing member extending between a front end face of the temperature-sensing portion and the bottom portion of the enclosing member. The element electrode wire includes a bend at an intermediate portion of the element electrode wire between the temperature-sensing portion and the joint portion.
摘要:
A method of making a semiconductor device manufacturing mask, which makes it possible to suppress a semiconductor-device global step and simply manufacture a highly reliable semiconductor device. Square dummy patterns each having one side of, for example, 0.25 μm or less are inserted into an area other than an actual pattern lying within a semiconductor device manufacturing mask to thereby uniformize a pattern density, enable etching processing without changing conditions set for every semiconductor device manufacturing mask an prevent an increase in global step of a post-CMP interlayer insulating film.
