I own and have read this book. While it is better than the average soldering book, it is not the first book that I reach for in trying to sort through a problem. It introduces a broad range of soldering methods with a reasonable amount of detail, b

Good points regarding Sanyo. I believe they were the first to introduce the "Direct Drive" concept. It's quite impressive. Panasonic probably ripped them off when designed their MSR's. It's interesting to note that an FCM-2 placing 96,000 comp. per h
