Yes, you need to design for what jlc stocks as basic parts to retain your sanity. Dont just slap down a 1206 resistor and call it good, jlc prob has no stock in

Yes, you need to design for what jlc stocks as basic parts to retain your sanity. Dont just slap down a 1206 resistor and call it good, jlc prob has no stock in that size in that value, but they probably have it in 0603. Once you get a handle for whats basic or very common extended parts, that sort of thing gets a lot easier. You kind of have to work backwards, ie if i need a diode i see what jlc has in basic and make my part choice accordingly.
