单板机作为写片的廉价设备,在写片量不大的情况下,使用简便.但是,在写片量大的正常批量生产中,就感到写片太慢,无法适应大批量生产的要求.单板机的操作方法要求插拔片子必须在断开电源的情况下进行,而断电后RAM存贮器中的信息就失去了,上电后必须重新调入.因此,手续很繁琐,写片多了往往还会出错.一旦出错,就得擦除、重写,花费更多的时间.片子的插拔也不是一件容易事,需要事先成型后才能顺利地插入插座内.拔出时,必须小心才不致于弄弯管脚,否则将花费更多的时间.以TP-801
As a cheap device for writing, the single-board machine is easy to use in the case of small amount of writing, however, it is too slow to meet the requirements of mass production in normal mass production with large amount of writing The operation method of the single board machine requires that the inserting and removing of the chip must be carried out with the power disconnected, and the information in the RAM memory is lost after the power is cut off and must be readmitted after the power is turned on.Therefore, the procedure is very complicated, If you make a mistake, you have to erase, rewrite, and spend more time. Inserting and removing the film is not an easy task, and you need to insert it in advance after molding. , Be careful not to bend the pin, otherwise it will take more time to TP-801
