I'm looking to learn more about the nuts and bolts of stem cell manufacturing for medical purposes but most of the resources I've found online are either marketing material from biotech companies, individual research papers or textbooks written 20 years ago.

Does anyone have any resources they can recommend that can get anyone up to speed on the big picture view of the technology? Specifically a textbook or encyclopaedia would be great

How much is new PCB Design FAFO?

I've been designing boards as an undergrad EE for a couple of years now and beyond simple breakouts or shields, I can't seem to nail the functionality of the boards on the first try. I'll try to breadboard where I can but often times the parts I want to use aren't available in DIP format so I'd have to skip straight to using SMD ICs and get them assembled at JLC which isn't exactly cheap.

I try to do circuit simulations beforehand to valid the schematic but half the time the IC I want to use doesn't have a SPICE model or if it does, half the pins I want to use is obscured (particularly for PSPICE).

My iteration runs typically run to several hundred bucks per iteration which is not great.

Is there anyway that you guys reduce errors when trying to design your boards? Is it worth salvaging SMD components and trying to reuse SMD ICs for the second iteration where you assemble them yourselves? Does anyone actually use SPICE simulations?
