    • Electronic circuits mounted on printed circuit boards, particularly circuits used for television receivers, are placed on a palette which is transferred by a conveyer. During transfer, test probes check whether or not the necessary parts are on the board as well as the suitability of their values to discriminate between defective circuit boards and those that pass. Then test probes monitor the characteristics of the parts and, if any require adjustment, this is automatically performed by a control circuit which controls a driver circuit. When the operational characteristics cannot be brought into predetermined limits by such adjustment, the circuit board is rejected as being defective. Thus, only circuit boards which have been properly adjusted are selected. In this manner, the selection and necessary adjustments may be made rapidly on a single conveyer line.
    • 安装在印刷电路板上的电子电路,特别是用于电视接收机的电路,被放置在通过输送机传送的调色板上。 在传输过程中,测试探头会检查板上是否有必要的部件,以及它们的值是否适合区分有缺陷的电路板和通过的电路板。 然后,测试探头监测部件的特性,如果需要调整,则由控制驱动电路的控制电路自动执行。 当通过这种调整不能使操作特性达到预定限度时,电路板被拒绝为有缺陷的。 因此,仅选择已经被适当调整的电路板。 以这种方式,可以在单个输送线上快速地进行选择和必要的调整。
