"Essential for Set Manufacturers! Reliability Evaluation and Analysis Guidebook for Electronic Components Part 2" Yasuo Imai / Tsuneo Ajioka / Oki Engineering I purchased this new and stored it without using it much. There is one brown stain on the side of the book (see photo 4), and creases on the front and back covers (photos 5 and 6). The inside seems to be in good condition with no signs of use. #YasuoImai #Yasuo_Imai #TsuneoAjioka #Tsuneo_Ajioka #OkiEngineering #book #Electrical/Mechanical Engineering / Electrical
