The EVM ships with the coupon plugged into the motherboard. If not already assembled, the basic hardware setup for the OPT4001YMNEVM involves plugging the coupon board into the motherboard socket. Take special care to make sure the coupon is oriented correctly as shown in Figure 1-1. Also note the warnings below. Specifically that the flex part of the coupon should not be pressed on. If unplugging and replugging the coupon into the motherboard, the coupon should only be handled by the rigid part and no part of the flex should be pressed on. Then connect the USB cable.
This EVM contains a flex PCB on which the OPT4001 IC is mounted. Flex PCBs are sensitive and should be handled with extra care. Special caution should be give not to press on the flex PCB as this can cause the EVM to break.
Many of the components on the OPT4001YMNEVM are susceptible to damage by electrostatic discharge (ESD). Customers are advised to observe proper ESD handling precautions when unpacking and handling the EVM, including the use of a grounded wrist strap at an approved ESD workstation.
