开云体育Nope.? Don't do videos. Now questions: 1) designing what?? Digital?? Analog?? RF?? 2) what level of complexity?? Do you need 1 layer, 2 layer, or 4 layer boards? 3) do you intend to produce these boards yourself? (it makes a difference in how you design them). 4) how big are they (can make a difference in either cost/who makes it or design/what program you use)? 5) what program do you use? 6) have you any experience with PC board design? 7) what level of hardware debug do you want to put into the boards (test points?? test pads?? logic analyzer breakouts?? ground posts?) 8) what kind of facilities do you have to make PC boards? 9) have you done any of this before? 10) what level (roughly) in electronics design are you comfortable with?? beginner?? what?
All of these things have a bearing on *how* you design something,
what design you come up with, how many copies you'll need before
you get one that works (know that one.....), and whether or not
you can make the board yourself. I know this may sound complicated, but
answers to some of these help others to gauge where you are in
experience, and what you need to know (IMHO, of course).
For me: (roughly)
1) designing:? Digital,? Analog.? Have done 100 pin flatpacks.
(self built), do 144 pin flatpacks when someone else builds
them). 2) I do double sided, plated through holes, silk screen, but
that's not me making them.? Have done toner transfer, 10 mil
trace, 10 mil spacing, double sided, wire stitch top and bottom
layers, tin/lead plated boards. 3) do you intend to produce these boards yourself? (it makes a difference in how you design them). 4) no bigger than 100 cm * 100 cm because of the board house limitations for cheap? 5) EAGLE 7.7, hobby (6 x 4 inch) license, can't sell the boards.? 6) by this time?? a fair amount, can always learn more 7) logic analyzer breakouts for digital, pin headers for some
signals, some test pads, ground connectors, monitor leds 8) used to make double sided boards, not plated through, designs got too complicated for me to make 9) lots 10) not beginner in digital, some analog, power supply Other people will have different opinions.
