Waterproof Cooling Fan PCB Design

Because to try to narrow the "Waterproof Cooling Fan" volume, are used in chip components, select the output power tubes installed behind the fold, the board as a plug mounted directly on the "Waterproof Cooling Fan" plugs, install a rear outlet. Speed function still have reservations, convenient motherboard testing. Plugs into the left part of the installation, the right part is "Waterproof Cooling Fan" socket. Overall area controlled within 10 * 30MM, pretty good bar. In fact, a short squeeze can squeeze point, but meaningful, no problem. Because traces of small complex on the use of double-sided circuit boards, FR4 material, thickness 1.0MM, successful control of the volume and cost.
