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

We would benchmark our times with the most experienced operator and them boost the time by 1/3. Example: If it takes Mary 3sec to insert the component, 3 secs to clinch and cut the leads (it is not advised to cut the leads after soldering), and 8 sec
