    • A PWM converter includes a power source current detector (9), current instruction generator (7), current controller (6) and a main circuit power control section (8), and the current controller is constituted of comparators (17, 18, 19) which compare the line current measurement results with the line current instruction values, and a logic circuit (10) which generates switching instruction signals (PU, PV, PW) based on the comparison results with use of timing signals so that the switching power devices (Q1-Q6) are selectively turned ON and OFF in the direction of reducing the difference between the line current measurement results and the line current instruction values, and thus essentially solves the prior art problems associated with gain adjustment of current error amplifiers, which is completely adjustment-free and yet inexpensive.

    • Processing is started (S1), and control of each mounting processing is sequentially executed under a mounting program command in a storage section (S2). An electronic component is positioned on a mounting head, then taken out and held (S3). A BGA component is positioned by position detection of a reference mark and inspection, and correction is carried out in response to discrimination of holding attitude. In inspection using the reference mark as a reference position, the quality of the component is discriminated, for example, loss and shift of a solder bump and insufficiency of the quantity of the solder (S4). A normal component is moved to the vicinity of a mounting position on a printed board on a mounting table by the mounting head (S5). A recognition mark at the target mounting position on the printed board is confirmed and recognized (S6). The mounting position is corrected by mounting positioning based on the results of mounting position detection and component inspection (S7). The height of the mounting head is controlled and the component is mounted (S8). In response to the presence or absence of a mounting component, the processing shifts to processing S1 for continuation of processing, or shifts to processing S10 for end (S9) and the processing ends (S10).
    • 开始处理(S1),并且在存储部中的安装程序命令下顺序执行每个安装处理的控制(S2)。 电子部件位于安装头上,然后取出并保持(S3)。 BGA组件通过参考标记和检查的位置检测来定位,并且响应于对保持姿态的区分来执行校正。 在使用参考标记作为参考位置的检查中,鉴别焊料凸块的损耗和偏移以及焊料量不足的情况(S4)。 正常部件通过安装头移动到安装台上的印刷电路板上的安装位置附近(S5)。 确认并识别在印刷电路板上的目标安装位置处的识别标记(S6)。 基于安装位置检测和部件检查的结果(S7),通过安装定位来校正安装位置。 控制安装头的高度并安装组件(S8)。 响应于是否存在安装部件,处理转移到用于继续处理的处理S1,或者转移到结束处理S10(S9)并且处理结束(S10)。

    • A parts container comprises a container body having a storage recess (5, 25) for storing a part (10, 30), a part engagement member (7, 27) provided in an opening of the container body and adapted to engage with at least a portion of an upper surface of the part stored in the storage recess and to releasably engage with and hold the part in a predetermined position, and an inspection hole (11, 31) provided in a portion of the storage recess to permit inspecting a condition of the part stored in the storage recess from outside. Thus an inspection member such as an inspection pin can be inserted through the inspection hole from outside the container body to perform inspection of the part stored, by contacting the inspection member with a connection terminal of the part stored for inspection.
