For the OTG adapter, in line to buy a Micro USB male head, then the welding line for electric iron in the above contact, the contact too close, electric shock is too small is too small, so fierce a few hours and not on welding. 1. when welding tin mucopoly will bring a shock next to weld together, tin stick less and not defended; 2. welding tin wire, total adhesion, rosin on, the solder wire is not sticky; 3. finally defended on, and is not strong enough a gentle touch, have lost. This is because last night, from 10 pm to 3 am., has not defended, ask God give me a solution!
Power can not be too high, there are hand can not shake, the heart should be stable. Can succeed
An electric iron is wound around a rough copper wire, and the rough copper wire is beveled on it
The Micro USB header is too small.First of all have good electric iron, a constant temperature, the iron head is conical, the material should not generally copper, is not easy to oxidation; using fine solder wire inside with rosin; using a scraper to remove the oxide layer on the surface of the head, if you peel the skin surface of the core wire is bright, can be directly on the tin the wire must be, copper or silver plated, some wire itself is not suitable for welding, do not eat tin, with such lines is certainly not good welding.Fix the Micro USB head on the table, hand the electric iron with one hand, solder the wire, the electric iron first preheat the welding point, then the solder wire is inserted, after 1 or 2 seconds, take it away, and the Micro USB head can not be shaken at this time.Do not use solder wire if solder joints are already tin and thread has been crossed.
