Hi All,
I recently designed a flow meter using MSP430 and did some EMI/EMC test. When ESD test was done, the unit reset immediately when High voltage was in contact with the body which was earthed. Give me a solution how to resolve the problem. I have a 30 multiplexed seven segment display in another board which was interfaced with the motherboard with FRC cable. When I remove the cable from the display board, the unit is not getting reset during ESD test. When I connect the FRC cable the unit resets during ESD test. Any suggestions or guidelines from your side.....
Regards,
Vamanan
