Soldering iron head maintenance
1.Due to electroplating, do not use a knife to file or grind the soldering iron head;
2.It is recommended to apply fresh solder on the soldering iron head during the first heating to remove the oxide wrapped on it;
3.When welding, try to use neutral active flux;
4.The cleaning iron head is made of original cleaning sponge and added some water, and it is not wiped with a cloth;
5.Keep the working surface always coated with tin, wipe only before use, and apply tin immediately after use;
6.If the soldering iron head is not tinned, use flux and cleaning sponge to clean the surface of the soldering iron head;
7.The welding temperature is higher than350°Cand suspend work for more than1If the soldering iron head is over the hours, the soldering iron head should be tinned frequently;
8.Do not remove excess solder from the soldering iron head before turning off the soldering station. This excess tin will protect the upper tin surface and prevent oxidation when the soldering iron head is reheated;
9.Avoid anti-bite soldering(Except for threaded head), otherwise it will affect the function of the soldering iron head;
10.If a bite occurs, try to remove the soldering iron tip when the iron is left hot;
11.To prevent bite, the soldering iron head can be removed from the soldering pen at intervals;
12.It is recommended to add water to the cleaning sponge as distilled water, because most of the minerals contained in tap water will corrode the soldering iron tips;
13.Pay attention to the storage of used soldering iron heads as follows:
a.Clean the soldering iron head with a cleaning sponge;
b.Wrap the soldering iron head with solder
c.Turn off the power supply and other soldering iron head cooling
d.Put the soldering iron pen on the soldering iron bracket.
Soldering iron head mouth shape classification and appropriate selection
IType: The tip of the soldering iron head is small.It is suitable for fine welding or when the welding space is small, and can also correct the tin bridge generated when welding the chip.
BType (conical shape)),:,BWelding can be welded at the front of the entire soldering iron head.LBType isBA type of shape, slender shape.It can operate flexibly in welding environments where there are taller components around the solder joints or narrow welding space.Application scope: Suitable for general welding, no matter the size of solder joints, it can also be usedBSoldering iron tip.
DType (one word batch of theme shape): Use the batch nozzle part to weld.Application scope: Suitable for welding with multiple tin quantity, such as welding environments with large soldering area, thick terminals, and large solder pads.
CType (oblique cylindrical): Use the beveled part of the front end of the soldering iron head to be soldered, suitable for welding that requires a large amount of tin.Application range: Application range of C-type soldering iron head andDThe type of iron is similar, such as large welding area, coarse terminal, and large welding pads.0.5C,1CThe soldering iron head is very fine and is suitable for soldering small components, or correcting tin bridges, tin columns, etc. that are produced during surface welding.2C,3CFElements such as welding resistance, diode and other components, which are suitableSOPandQFPCan also be used4C,Suitable for rough terminals, ground on the circuit board.Power sources and other welding occasions require large calories.
KtypeTheFeatures:Use knife-shaped parts welding, vertical or pull-on welding type welding, and is a multi-purpose soldering iron head.Scope of application: suitable forSOJ,PLCC,SOP,QFP,power supply,Grounding parts, corrected tin bridges, connectors, etc. soldering.
Choose the right soldering iron head shape:
1, According to the size of the solder joint: Selecting the appropriate soldering iron head according to the size of the solder joint can make the work smoother.IThe nozzle is used for welding joints with precision welding and limited welding environment.BType andCThe solder joints are relatively large, which can improve efficiency and save welding time.
2, Solder joint density: Soldering on denser circuit boards, using a thinner soldering iron head can reduce the opportunity for forming tin bridges.The solder joints are relatively loose, such asICFeet, totally usefulKOne-sharp dragged it out.
3, Depending on the shape of the solder joint: Due to the different overall foot shapes of the components, we are also required to choose the corresponding easy-to-use soldering iron tip type.For example, resistors, capacitors,SOJchip,SOPThe chip requires the coordination of different soldering iron heads to improve work efficiency.
