I'm so envious to those people who can make 6 mil printed circuit boards at home and solder 0.35mm BGAs to them in their freaking precise temperature oven. Now I genuinely appreciate how freaking cheap $2 per square inch is!

I tried laser cutter, laser printer, photoresist, ferric chloride, silver paste, vinyl layers, copper film, Avery stickies - nothing works at this tiny size! Seems that the biggest feature you can have at home is about 0.5mm on multi-layer _repeatable_ prototyping technology. Either glue, or etchant goes everywhere and either makes your holes non-conducting, or bridges neighbor pads.
