We are looking for an individual capable of reverse-engineering a double-sided, combination hole-through / surface-mount PCB. The board will be a pulse-width modulation board used to control hydraulic valves. Input voltage will range from 12 to 30 volts DC. Output needs to be squarewave with up to 2.5 amps output current. Frequency needs to be changeable by changing a resistor in the timing circuit. We would prefer to send a prototype board to the winning bidder (any where Fedex can go). We will accept a copy of the board we send or designer's own ideas. The PCB must be analog.
