Hi, I have some questions.I will try to build a breakout board for micro sd card (I know they exists but I want to build one myself, not ordering).My plan is to attach a sd socket, tiny transistors and then in the end drill some holes so you could use jumper wires to attach the whole circuit board to your existing project. I will try to stick with surface soldering so the board could be very small and I don't have to drill so much holes.I was wondering if it's possible to make a pcb that have that small lines? Don't know what the "lines" are called but will the iron chloride remove those or will they stay?Tldr; How small and precious could you be when using the iron chloride method?
About ferric chloride: it can give very precise results. From my experience, what determines how precise and how thin your traces can be, isn't the etching method, but the trasnfer method. Some transfer methods issue much more precise results than others. I've had good experience with toner transfer, with traces as thin as 8mil, although 99% of the time I keep them wider than 15mil just for safety.
Edit: Never mind I searched for it on google. But what other transfer methods are their?
