摘要:
The present invention provides a battery block that accommodates unit cells having higher capacities, and, even in case of abnormal heat generation in the unit cell, does not cause abnormal heat generation in the neighboring unit cells, thereby preventing a chain reaction of degradations and abnormalities of the accommodated unit cells. The battery block of the present invention includes a battery case having a minimum thickness section satisfying the relationship “K2/K1≧K3−1”. K1 is the thermal conductance between the battery case and the unit cell. K2 is the thermal conductance of the minimum thickness section of the battery case between two neighboring holes for accommodating the respective unit cells. K3 is a ratio between the abnormal heat temperature of a reference cell and the ambient temperature causing abnormal heat generation in this cell.

A heating and pressurizing apparatus (101), to which a circuit board (70) with electronic components (8) pre-bonded thereto via bonding elements (9) is carried in, is provided. The heating and pressurizing apparatus post-bonds the electronic component to the circuit board by heating and pressurizing the electronic component by a contact member (1211) having a heating device (122). By executing the pre-bonding and the post-bonding of the electronic components to the circuit board independently of each other, the time required for the post-bonding can be reduced, compared with the conventional case, and the productivity of the whole mounting line can be improved.
摘要:
A pressurizing method for pressurizing a second component arranged on a first component, against the first component by using a pressurizing apparatus having a stage on which the first component is mounted, a tool, and a protection sheet supplying section. The tool is disposed so as to face the stage and moved between a first position at which the tool faces the first and second components while spaced therefrom, and a second position at which the tool is biased toward the stage to pressurize the second component against the first component. When the tool is at the second position, the protection sheet supplying section supplies a protection sheet so that the protection sheet is placed between the second component and the tool.
摘要:
There are disclosed an apparatus for mounting electronic components, with which the electronic components can be reversed, up and down, and mounted onto a circuit board in a short mounting process time by performing picking up, delivering and receiving of components between heads, and mounting of the components onto the circuit board in parallel. A plurality of reverse-supply heads are mounted on a component supply holder for performing indexing rotation, while a plurality of mounting heads are mounted on a component mounting holder for performing indexing rotation in synchronization with the indexing rotation of the component supply holder. By (i) picking up an electronic component, (ii) delivering the electronic component from the reverse-supply head to the mounting head, and (iii) mounting the electronic component onto the circuit board at prescribed positions, operations from (i) to (iii) can be carried out in parallel. Thus, the electronic components can be mounted onto the circuit board in a short process time.

A divided component separated individually beforehand is supplied in a state while stored in a storage body, taken outside by a take-out and storage unit, and a component is mounted on the divided component by a mounting unit, and thereby a divided component with the component is produced. A plurality of the produced divided components with the components mounted thereon are collected into the storage body. Since the component is mounted on the already divided component, as compared with the prior art, no trouble is given rise to at a junction part between the divided component and the component, thus contributing to an improvement in product quality.

Disclosed are an apparatus and a method for bonding electronic components, a circuit board, and an electronic component mounting apparatus, whereby various kinds of circuit boards can be manufactured, each by a small amount, with high productivity as compared with the conventional art. There are provided a stage member and a heating device, so that a circuit board is heated by the heating device while held in contact with the stage member, which stage member has a size almost equal to that of one circuit board. Generation of losses can be reduced for compact circuit boards, and heating can be performed individually, correspondingly, for each kind of circuit board. Manufacturing various kinds of circuit boards, each by a small amount, with high productivity as compared with the conventional art is enabled accordingly.
