The right one is soldered, but it's always soldered, and the wires don't go on tin. It's normal on the left. Wires can reach the tin. Every time I burn the enameled wire on the surface of the wire (because I'm trying to get the wire off my headphones, it's too small to be scraped with a knife) why is there something wrong with it?. Power issues? The tin problem? Or operation?
First of all, the end of the wire should be clean (polished with fine sandpaper), and then let the end of the hanging tin, and then welding, electric iron 30W on the line
Never burn wires; otherwise, oxides form surface tensionIt's hard to hang tin. The other is the soldering flux, and this one must be thereJust a little. It's easy to weld.I used to be the same as you, a pair of iron directly on, and later found,Apply a bit of flux (rosin). These are simple and cheap. You can buy 1 cans for 5 yuanIt's been used thousands of times.
Now headphones are basically the heart lineSelf-adhesive, non welding coating, insulating layer!That is, it can be coated with tin!1. the ends are dipped into the chlorinated rosin!2. take out and place on the insulation board!3. back and forth with Zhanman Rongxi tip friction on tin!4., after plating the upper part of tin, heavy immersion rosin!5. throw the tin out of the tin!6. use rosin soldering tin to solder it again!7. until the light can be!
