Hi Nick
The oven I'm using is a "VonShef 46L Mini Oven". I knew the E1T boards
were going to be about 100mm x 340mm so I needed an oven with sufficient
area to take that size board. In practice that oven is 390mm wide
internally. I followed the Whizoo installation/build recommendations,
especially for insulation and installing additional bottom heating
elements. I bought a conventional 300 degC rated oven lamp as the oven
does not come with an oven. I used a small Chinese switcher PSU for the
5V and Chinese solid state relays to switch the three heaters separately.
No problems with it at all. I have run a lot of tests, measuring the
temperature in the centre, edges and corners and see little or no
temperature differences. Much better than my previous uninsulated oven.
I've reflowed 15 52mm x 52mm boards in one go spreading them out in a 5
x 3 array and there was no differences between the centre and the corner
boards. I've used both common lead free paste, lead containing paste and
low temperature paste by editing the profile text file.
I bought the oven through Tesco as I could get free delivery to the
local store in Dingwall. So was cheaper than other box-movers. Not sure
but a quick look for sellers shows it is out of stock everywhere
suggesting the model might be superseded. B'gg'r't.
