The copper core of the iron head is made of pure copper, the outer layer is plated with ferroalloy, the outermost layer is plated with tin, if you weld magnetic materials such as speakers, you need to use a pure copper non-magnetic soldering iron head, but the pure copper soldering iron head is not durable, according to their needs to buy!

Soldering iron tip oxidation on tin, is a common problem, even if the constant temperature iron working at high temperature is inevitable oxidation. The reason is that the use of the problem, the iron head working temperature is too high, and a long time heating and other issues. But its main reason is still high temperature and long time working problem. Solution:

(1) do not let the iron head directly with corrosive object contact

(2) Finish using the soldering iron to turn off the power supply in a timely manner, and then plug in again do not be afraid of trouble.

(3) Each time after using the soldering iron to timely tin maintenance!

Warm tips: some customers due to lack of experience, in the case of no tin at all, the soldering station temperature to a very high, resulting in the head of the soldering iron dry burning oxidation can not be on the tin, here to remind, the new head is recommended to 250-280 degrees or so, on the tin to protect, and then raised to the use of temperature, so that the head is not in direct contact with the air is difficult to oxidise! 250 degrees if the fine soldering tin does not melt, then please check! Calibrate the temperature of your soldering station or replace it with better solder wire! If the tip is oxidised, use a sponge with solder paste or rosin and fine sandpaper to remove the oxidised layer and resurrect the tip!

Name: High-grade soldering iron tip for soldering station, lead-free and environmentally friendly 900M series soldering iron tip

Use: This product is suitable for 936 soldering station, 937 soldering station or all kinds of 900M series special handle. All brands of external heat type internal heat type soldering iron is not universal. Please watch the product description or consult customer service before purchase. Please do not buy back because of cheap and can not be used to give us a bad review, thank you!

Instructions for use: any time you use a brand new soldering iron head, please follow the steps below, will make the soldering iron head life greatly extended.

(1) Adjust the temperature setting control to the low temperature position. Switch on the power "switch".
(2) After heating up to 200℃, add tin wire containing flux on the tinned surface of the soldering iron tip.
(3) After five minutes of continuous heating at 200°C, turn the temperature setting control to the appropriate use temperature position.
(4) After reaching the appropriate temperature, you can start using.
 

Note: Whenever a brand new soldering iron tip is used, it is best to remove the tip and clean the internal foreign matter every day!

How to choose the right one for you?

Type I

Characteristics: The tip of the soldering iron is small and thin.
 
Application: Suitable for fine soldering, or when the soldering space is narrow, also can correct the solder bridge when soldering chips.

Type B/LB (Conical)
 
Features: B-type soldering iron head is non-directional, the entire front of the iron head can be soldered.

Application: Suitable for general soldering, regardless of the size of the soldering joint, can also use the B-type soldering iron head. LB type is a kind of B type with slender shape. It can be flexibly operated in the soldering environment where there are high components around the soldering point or narrow space for soldering. Operation.

D type / LD type (one word batch tip shape)

Features: Soldering is performed with the nipple portion.
 
Application: Suitable for soldering that requires a large amount of solder, such as large soldering area, thick terminals, and large soldering pads.

C type/CF type (slant-cut cylindrical)

Features: Use the bevelled part of the tip for soldering, suitable for soldering that requires a large amount of tin, CF type tip only has tin plating on the bevelled part, only the bevelled part of the tip can be coated with tin when soldering, so the amount of tin coated will be different from the C type tip, depending on the needs of soldering and selection.

Application range: The application range of C type soldering iron tip is similar to D type, such as large soldering area, thick terminals and large soldering pads. The 0.5C, 1C/CF, 1.5CF tips are very fine and are suitable for soldering small components or correcting solder bridges and pillars produced during surface soldering. If only a small amount of solder is required, it is better to use the CF type soldering iron tip which is tinned only on the bevelled side. 2C/2CF, 3C/3CF type soldering iron tips are suitable for soldering resistors, diodes and other components, and SOP and QFP with large pitch can also be used. The SOP and QFP with large pitch can also be used.
 
4C/4CF, suitable for thick terminals, circuit board grounding. Power supply and other soldering applications that require high heat.

K type
 
Features: Use knife-shaped part of the soldering, vertical or pull soldering can be used, is a multi-purpose soldering iron head.

Application: Suitable for soldering SOJ, PLCC, SOP, QFP, power supply, grounding parts, correcting soldering bridges, connectors and so on.

H type
Features: The tin layer is on the bottom of the tip.

Application: Suitable for soldering SOP, QFP with large pitch. 

Selection of soldering iron tip.

1.Size

i) The size of the soldering joint: according to the size of the soldering joint to choose the appropriate iron head can make the work more smoothly. If the tip is too small, the temperature will be insufficient. Too large, there will be a large amount of solder dissolved, the amount of tin control difficult.
 ii) Density of the soldering point: In the more dense circuit board for soldering, the use of smaller and thinner iron tip can reduce the chance of the formation of tin bridge.

2. Shape
i) Types of soldering components: Different types of electronic components, such as resistors, capacitors, SOJ chips, SOP chips, require different soldering iron tips to improve work efficiency.
ii) The ease of contacting the soldering point: If the position of the soldering point is surrounded by some higher electronic components which are difficult to contact, the longer and younger shape of the soldering iron tip can be used.

iii) Requirement of tin volume: If more tin is required, use a soldering iron tip with a larger surface area of tin plating.
