Mic. contains a FET within its case. Generally, semiconductors are easily weakened by over-heating, over-charge of voltage.正常焊接的注意事項(xiàng)：Special caution is needed for proper soldering as follows:1.用15W-20W控溫烙鐵，溫度控制在260-280進(jìn)行焊接。Use 15W-20W soldering iron and maintain 260-280 in operation.2.焊接時(shí)間在每個(gè)焊點(diǎn)上控制在2秒鐘以內(nèi)，不允許時(shí)間過長(zhǎng)。Soldering should be accomplished within two seconds at each terminal so as not to be overheated.3.焊接時(shí)間過長(zhǎng)，或焊接溫度過高，不但會(huì)引起場(chǎng)效應(yīng)管發(fā)生變化，并且話筒里面的塑料腔
