For BD601 or U101 Model Rev. Rev. 0
1. Preparations for rework 2. Components
1) F101 (FUSE AXIAL 02153.15MXK17P, T3.15A/250V)
1) Solder
2) Solder wire
3) Multi Meter (beep and diode mode needed)
4) IPB
2) D101, D102, D103 (DIODE 1N4007 1A 1000V)
5) Components (described right side)
6) De-solder
3) BD601(DIODE BRIDGE RS405M 4A 600V)
4) U101(LNK362PG, STBY IC)
Nipper Recommendation:
In case of either BD601 or U101 is damaged,
LGIT suggest that all indicated above components should be replaced.
Because when simulating surge test, D101,D102, D103 also could be damaged
