You may want to either open up the bottom of the vias so they will not "volcano". Or you will want to seal both sides. It never works having one side of the vias masked and the other open with HASL. Russ

Carol: If you would have problems both covering the via and keeping mask from the BGA pads, maybe you via are too close to the pads. Maybe some of the IPC pad design guidelines would help.

Does anyone know the specific type of catridge to be used for this machine? For this printer with the optional automatic dispensing machine, the 1 kg. catridge does not seem to be the average SEMCO catridge.

Hi Sue, We have a Micromat Router & a Sony Router which we use for Rigid & flexi rigid. We use a press for Flex only (or where flex is joining the boards) & a scoring machine for other rigids. Hope that helps, Rob.

Bob Willis has some information on his website. "Simultanious double double sided reflow". I believe there is a free download there also. http://www.bobwillis.co.uk/ Good luck
