| Hi Chrys! | | I've also heard stories of the water-based material "attacking" the inner workings of their spray nozzles - probably due to the water hanging around parts and corroding them. | | Did you have any such problems with the USI ultrasoni

Mornin! We just had vendor in here pitching a "low-temperature rework system" which was intriguing, but too expensive. He did get me to thinking though, beyond heating ceramic caps before hand-soldering them, it seems like it would be advantag

| Tony | | Although I agree in principle with Dean that 45 Degrees would be ideal, most of the squeegees I have worked with have been 60 Degrees to the stencil surface. This seems to work best with metal squeegees when printing HASL boards, because
