Hi there, Silicon chip Magazine have a electronic project on exactly this,
they supply the pcb you fit the parts.
from memory the pcb is about $15.00 AU , has a few smd parts as well as the micro
which is also smd but every thing else is through hole ,
you use a toaster oven which plugs, into the controller, controller has buttons for inputting the temp setting etc, which you can read on a 20x4 screen lcd, it PID controlled.
check it out, maybe its what you are after

should be may and april issues

I looked through the messages for this group for
the last couple years but do not see any discussion about DIY
Toaster reflow ovens.? I know it used to be an easy thing to find
on the web but I have been searching for a few months now and all
the ones Mr. Startpage (pronounced Google) has given me have been
7 to 15 years old and use obsolete and unobtainium parts.? I would
love to buy a T962 or T962A but the price is too high for me as I
am on a fixed income.? Someone on a British forum said someone was
selling T962's on ebay for $129 usd but when I checked the sale it
would not sell to USA.? I know the T962 series would require a lot
of modifications to make it dependable but that would be easier
than building from scratch.
Without something like the T962 series I had seen the Controleo3
but not sure what I need (the $109 kit, the $249 kit, or the $299
kit) and which toaster oven (convection or conventional).?
Does anyone know of a current DIY toaster reflow oven project on
the web that would not cost a fortune to build?
I know there was an article in a professional journal about 7
years ago that used a Black and Decker oven from Amazon but I
can't find that article and do not remember what journal.? Even if
I find it, will it work.
A friend suggested that I use an Arduino but I am not sure what
the profile is supposed to look like.? My idea was that it would
1.? Come up to a board heat up temp (100 C maybe)
2.? Hold that temp for some length of time
3.? Measure the board temperature to be soldered until it comes up
to temp.
4.? One up to temp then raise temp to solder paste temp (450 C?)
5.? Hold for a time (30 seconds?)
6,? Cool down to original warm up temp (100 C)
7.? Cool down to room temp before opening the door.
Have I missed anything?
Does anyone know of any forums that deal with this type of
project?? Does anyone know of a Arduino forum that deals in DIY
projects?? I am on a couple facebook groups but see very little in
the way of actual projects and it seems that Facebook does not
allow sharing files very easily where 开云体育 or Googlegroups do
allow easy file sharing.
The object of course is to solder smt parts to pc boards.? One
project I have uses a FPGA144 and a QFFN64 chip.? It was suggested
that I drag solder them but I do not feel comfortable doing that
and the parts were rather expensive and I can't afford to use them
for practice.
Can anyone point me in the right direction?
Thank you.
