a) "Super glue" is a specific type or just a commercial name? What could be the equivalent in the local (Argentina) market?

b) You bond the board to what?

c) How do you separate it it after completing the PCB?

d) Have read of people doing the drilling before milling. Any comments?


My MF70 is closer (maybe in 8 weeks I will have it!

I feel like trying to learn basic rocket science with all this. I hope one day my PCBs would look like the one shown some posts below. Wow!
Super Glue is a trade name for cyanoacrylate glues (CA): (http://en.wikipedia.org/wiki/Cyanoacrylate) There are many, many, many trade names and viscosities. I just buy the cheapest I see, usually in small tubes in a quantity at a discount store. Using a thin CA, (which is like water) and placing a few dots on the revese side of the pcb to be milled it is then glued to a piece of flat aluminum plate, tooling plate. Tooling plate is aluminum that is ground to a mirror flatness. I bought mine from ebay. CA debonds with acetone. I drill before I mill as I also use alignment pins for exact registration. By making the drills for the alignment pins part of the design process, you have perfect registration from side to side and operation to operation. See Fixtures and Tooling on my website: http://millpcbs.com/ If you want to look at something to give you how capable you can be with more technique than expensive equipment see my video: "http://www.youtube.com/watch?v=lhdqBrciQZU"]YouTube - Milling a fine trace double sided pcb Make sure to see the pictures at the end to get a size perspective.
