I am amazed by this Industrial and Scientific Tool for soldering and reballing .Thanks to my knowledge gained in practice, I found the tool very handy, and it made my work easier than ever. With this tool, I was able to perfectly align the solder balls during the reballing job, thanks to its precise stencil and soldering abilities. Though the price is a bit high it is worth the investment, and I would highly recommend it to professionals in the industrial power tools category..
