(1) please use every termination and take ground as largely as possible. (the parts may not perform well depending on how the ground is taken.) (2) please wire it so that a ground of circuit side (termination ) is not connected to a ground of power side (termination ) in other parts either. for soldering, please perform a temperature pattern of the right note for reference. please do not perform heating more than 240 degrees celsius 10 seconds. i received the internal joining, but i melt, and such as a short circuit, opening, a gap of a case may occur. this part is the lead-free correspondence kind that i received.
