STR—S6707是较新型的开关电源厚膜稳压输出块,其中包含有:振荡、比例均衡、开关激励及反馈保护、热保护等多种功能电路,目前市价较贵。其内部可基本划分为功能电路和开关管输出电路两大部分,其两部分电路一般不会同时损坏,故遇有该厚膜块损坏时请不要轻易丢弃,完全可以利用搭配方法修复再用。具体修复方法如下:当测定块内开关管击穿损坏时,不必用锯动块体方法去分离其内部电路(这是区别它种修复方法之处),可将块①脚和③脚由电路板摘出合并焊于②脚或剪断,②脚不动(①脚为开关管c极,②脚为e极,③脚为b极。②脚不能由电路板摘出,因
STR-S6707 is a new type of switching power supply thick film regulator output block, which contains: oscillation, proportional balance, switch excitation and feedback protection, thermal protection and other functions of the circuit, the current market price is more expensive. Its internal can be basically divided into two parts of the functional circuit and the switch output circuit, the two parts of the circuit will not be damaged at the same time, so in case of the thick film block damage, please do not easily discarded, can use the method of repair and reuse. The specific repair methods are as follows: When the test tube switch breakdown damage, do not have to use sawing block method to separate its internal circuit (which is the difference between the kinds of repair methods where), the block ① feet and ③ feet by the circuit The board is removed and merged and welded on ② feet or cut, ② feet do not move (① feet for switch c pole, ② feet e pole, ③ feet b pole. ② feet can not be removed from the circuit board, due to
