Ideally the middle leg (drain) would not carry any current, it instead flows via the heat sink to the back plane of the HY4008 - this connects to the drain. That is one reason for using life heat sinks and *no* heat sink compound at the mosfets. The source leg needs to carry the full current and I see in the pic a build up of solder for that, not sure if the PCB tracks are adequate. Klaus
