In the automatic soldering, how to make the soldering iron tin can maintain a very good fluency is essential, welding Fung Electronics has a wealth of experience in this regard, the they accumulated the experience to share with everyone.
A, automatic soldering tin, tin wire selection to the right
Solder in automatic soldering machine, often make the iron head to maintain an appropriate amount of tin, tin wire inside the tin content appropriate to the. In the selection of the tin wire, solder wire should try to choose thicker, so you can make the iron head tin volume sufficient, not exposed to the air and to make iron head accelerate oxidation.
Two, the iron head to maintain a clean state
Since the use of automatic soldering machine soldering iron head, must put on the oxide clean before welding, such ability in welding when the solder has a good flow state. At the same time in the welding is completed, also want to add a new layer of tin in the soldering iron head, so you can make the iron head not oxidation too fast. When cleaning the iron head, special cleaning sponge can be used wet wipe soldering iron head of the flux residue and oxide, or give them to scrape with a blade, at the start of a welding.
Three, the iron head surface often coated with tin, to increase its durability.
Especially when automatic soldering machine without, often coated in a layer of tin oxide opportunity, this can greatly reduce the iron head, iron head is more durable.
Four, iron oxide cleaning
In the automatic soldering iron head, if it is found that the tin plating layer has a black oxide, to timely cleaning, cleaning sponge cleaning and blade are possible, so as to ensure the good fluidity and soldering heat.
Five, the iron head selection to the right
In the automatic solder, soldering iron head type and the choice must choose the appropriate. Soldering iron head selection is not correct, not only affects the efficiency of automatic soldering machine, and the welding quality will be greatly reduced. At the same time, the iron head of different models of the heat capacity is not the same, the iron head is bigger, its heat capacity is greater. The principle is to choose the soldering iron head, iron head does not affect the adjacent element as the foundation, then is the choice of geometry can fully and contact pads shall prevail, only in this way in the welding time can be handy.
In short, automatic soldering is a very complex process, when in welding, we only use the scientific attitude to pick a soldering iron head, in order to achieve a multiplier effect in welding.
