Hello - What is the difficulty level in soldering this IC chip to a PCB ?

I use a modified one of something like this (can't find the actual one online). Its important that it has a cast iron top for thermal stability (not an open ring or an induction hob). I replaced the crude 'temperature' control with a thermocouple epoxied into a hole in the casting from underneath and a simple home-brew temperature controller/display, though you can buy something suitable on eBay/etc. for a few $$$.
An improved thermostat is essential. The bimetallic strip that is fitted as standard is almost acceptable for heating a pan with a litre of water in it. With almost no thermal mass, the temperature is all over the place.
A single sheet of metal (upturned baking tray) works pretty well with a hot air tool as it spreads the heat from the tool out underneath the board, like preheating the bits you haven’t done yet.
