What is the function of rosin in the use of electric irons?I didn't use any rosin when I used it. I didn't know how to use it
The soldering flux has been painted on the circuit board.
You are factory welding or repair ah tin wire and now there are rosin can generally be if the repair welding is suggested to be used in the production of some rosin paste. It will not because of the easy to cause the circuit board rosin appearance after welding unless the cleaning circuit board is mainly rosin flux can greatly improve the welding effect the analogy is detergent washing washing out of the bowl is clean with a detergent bowl cleaner repair if small solder joints can be directly used electric iron stick in the rosin and large welding solder joint can be directly put small pads of rosin in welding production then directly welding.
To prevent the welding surface is oxidized, because after oxidation, cannot produce weld and welding.
