Teardown of a DeWalt DW9118 7.2V – 14.4V Battery Charger, with Macro & Die Shots of Components

Another great video from Electronupdate, this time examining a DeWalt 7V-14V 1-hour battery charger, which failed after 5+ years of dedicated service. The video (below) contains some interesting commentary on the contents of the fuse from the circuit, as well as non-component material used throughout the manufacturing of the board, and of course some great die shots of the microcontroller (Zilog 86C04) used by the circuit – including copyright dates strewn throughout spanning as many as 36 years. Fun!
