I have looked around there are two types: Spot heater (from under) using hot air via 1" or 2'" dia "round salt shaker holes" or planar heater (many types) that heats over large area of PCB. Is spot heater I thought would fit the bill?
Goal for our SMD rework for repairs, using hot air and hand solder irons in order to have heat requirement lower and easier to work with especially the power planes and less stress to the circuit board components. So soldering can be done at less heat setting with soldering irons and hot air around 375-400 instead of much higher and time spent much less during soldering.
Idea is: Spot heat PCB to 100C or so, and work on PCB easier. My wish is handle typical larger cellphone PCBs and would be nice to handle notebook and computer motherboards, cards board for any repairs.
We already have iphone sized surface heater and works rather well for iphones but too specialized for anything else.
Don't forget about the microscope height and chairs height issue too as the heater requires PCB held at much higher height than sitting on the mat.
Cheers,
