13.2. How to Replace the LLP (Leadless Leadframe Package) IC

Note:

This description is only applied on the model with Shield case.

13.2.1.

Preparation

• PbF (: Pb free) Solder
• Soldering Iron

Tip Temperature of 700



F ± 20



F (370



C ± 10



C)

Note:

We recommend a 30 to 40 Watt soldering iron. An expert may be able to use a 60 to 80 Watt iron where someone with less
experience could overheat and damage the PCB foil.

• Hot Air Desoldering Tool

Temperature: 608



F ± 68



F (320



C ± 20



C)

13.2.2.

Caution

• To replace the IC efficiently, choose the right sized nozzle of the hot air desoldering tool that matches the IC package.
• Be careful about the temperature of the hot air desoldering tool not to damage the PCB and/or IC.

13.2.3.

How to Remove the IC

1. Heat the IC with a hot air desoldering tool through the P.C.Board.

2. Pick up the IC with tweezers, etc. when the solder is melted completely.

Note:

• Be careful not to touch the peripheral parts with tweezers, etc. They are unstable.

When it is hard to melt the solder completely, heat it with a hot air desoldering tool through the IC besides through the
P.C.Board.

3. After removing the IC, clean the P.C.Board of residual solder.
