Underneath it has a small metal pad which is supposed to be soldered to the circuit board copper area which acts as a heat sink. I cannot solder the IC to the board like this, that needs professional and costly assembly and removal also becomes difficult.

Hi Tony

I've had good luck with solder paste and a toaster oven for these kinds of ICs.
