900M soldering iron tips is for Hakko soldering iron station at the beginning , and now there are many 900M solering iron tips made of different factories with different brands,such as AOYUE 900M soldering iron tip and BEST 900M soldering iron tips. They almost with the same use and compatible with each others, the only difference is they are different quality with different prices.

900M soldering iron tips have many types such as I type,B type,D type,C type,K type, below is the difference among them:

900M I type soldering iron tip is also called fine tip, it is suitable for soldering fine pitch or small gap compents. It can be also used when soldering bridge happens.

900M B type soldering iron tip is also called conical soldering iron tip with no direction, and all tip end can be used for soldering. It is suitable for general soldering regardless of the size of the solder joint.

900M D type soldering iron tip is suitable for rework components with large soldering area,thick terminal or large soldering pad which needing more solder when rework.

900M C type soldering iron tip is also called bevel soldering iron tip, it uses front bezel tip to solering components with large soldering area,or thick terminal,or with large soldering pad which need more solder. C type has many kinds: 0.5C, 1C ,1.5CF and so on, and they are very fine soldering iron tip suitable for very small components rework or amending the solder bridges, solder columns caused in soldering process. If only a small amount of solder,CF soldering iron tip is ok. 2C,3C soldering iron tips are suitable for soldering resistors, diodes or similar components and SOP or QFP with larger pitch. 4C soldering iron tips are for soldering thick terminals,grounding of mainboard and power supply which need larger heat.

900M K type soldering iron tips are also called blade type soldering iron tips. They use the knife-shaped part to solder, and it can realize erect  or pull type soldering . K type is the most widely used because it is multifunctional for soldering SOJ, PLCC, SOP, QFP, power supply, grounding components, and revising soldering bridge,connectors and so on.
