I am trying to do some surface mount soldering for my project and have hit a few snags.
My hot air gun works perfectly fine for most of the PCBs I am making but one type in particular is problematic. Due to the fine pitch of the chips I am using, and the number of very small components on the board I cannot seem to get a good board out of my current process as the components have a bad habit of shifting due to the air flow.
Due to the fact that the board is 35cm long it will not fit in any desktop ovens I have found and I just don't have the money nor the long term need to invest in any industrial equipment.
I've tried ordering two different induction hobs off of amazon in the hope that I can run them at somewhat accurate temperatures but I have hit the same problem in both cases. My tray started smoking and when I checked the temperature with a laser thermometer both heated up in excess of 440 C when I had them set around 160.
I think this may be due to the size of the tray I have to use, rather than a fault with the hobs themselves?
Anyone able to point me in the direction of an oven that is large enough for what I need but is under £250? Or perhaps someone can recommend a hot plate that will do what I am expecting / an entirely different process?
