10、leeceChangzhou ChaoQi11连接线 WireUL1571 32#关于焊接操作Regarding the soldering operation每个驻极体传声器中都有一个场效应晶体管，半导体很容易在过热电压过高而受到损害。Each Con. Mic. contains a FET within its case. Generally, semiconductors are easily weakened by over-heating, over-charge of voltage.正常焊接的注意事项：Special caution is needed for proper soldering as follows:1.用15W-20W控温烙铁，温度控制在260-280进行焊接。Use 15W-20W soldering iron and maintain 260-280 in operation.2.焊接时间在每个焊点上控制在2秒钟以内，不允许时间过长。Soldering should be accomplished within two seconds at each terminal so as not to be overheated.3.焊接时间过长，或焊接温度过高，不但会引起场效应管发生变化，并且话筒里面的塑料腔
