When I stumbled across these small, dual channel, "metal-oxide-semiconductor field-effect transistors" (MOSFETs) online, I knew I had to use them somehow. As the Electrical engineer for our team, I've set myself on a mission to make each ROV faster, more efficient, more economical, and more compact. This new circuit board is a great example of that. These three dual channel surface mounted MOSFETs are almost half the price of the single channel MOSFETs we used for last year's Relay switching board, take up significantly less space (this one interfacing board does the job of three of our interfacing boards last year), and finally, the new design allows us to add an extra H-bridge on our submersible board, giving us a ROV that should be more maneuverable and more efficient.

Hmm.. Sounds like good. Can you please post more details about this circuit board. pcb manufacture
ReplyDeleteSorry for the late response. The circuit board shown above acts as a communication board between our microcontroller and our motor control board underwater. The board amplifies and isolates the signal coming from our microcontroller, protecting our more sensitive electronic equipment and translating our basic logic signals into something that is powerful enough to be carried across 70 feet of CAT5E cable. As with all of our circuit boards, this board was manufactured using the toner transfer method. This method is far cheaper than many commercial solutions, and allows us to make one of these boards in about 6 hours.
ReplyDeleteTips to pick good pcb assembly house?
ReplyDeleteAll of our boards were designed printed and populated in-house, so I don't really have any recommendations for PCB-related companies, sorry.
