Professionally made prototype pcb's are inexpensive enough now that I don't think I'll try this, but have fun! -John Robert Spanton wrote:
I make PCBs at home with a minimum track width of about 0.12mm. I'd like to use BGA components in my designs, but possibly the biggest problem lies in actually getting the tracks out from under the BGA. Looking at other designs, it looks like it's possible to get all the tracks out from under the BGA on a 2-sided board but only if you can get vias between the pins of the BGAs. Drilling those vias accurately is more difficult - hence my need for an x-y table... Then once you've got those vias, you've got to get some sort of conducting stuff through them. I don't think sodlering anything through them is an option, as they wouldn't be flat enough to go beneath the BGA. The only chemicals I've seen for plating PCBs seem quite expensive (for a student!). I'd be interested to know if there's anyone who can suggest cheap ways of copper plating the holes.
