    I just wanted to see if anyone here has any personal experience reballing BGAs on Consoles and PC Motherboards.
    I guess my inquiry has to do with the preheating equipment. I was contemplating between putting an arduino and relay in a toaster oven, or modifying an electric griddle with boltholes, standoffs etc.

    I think the toaster oven would be great for drying and unwarping boards, but a griddle would offer much more open access to the board being reflowed/reballed and already has *decent* temperature regulation. I don't need both on my workbench. Any input is appreciated.

    If you just want to reflow it shove it in the oven. Or are you talking about building boards with BGA's on them?

    Actually talking about 150C preheat for reflow/reballing. Plastic jacks, USB ports, 105C capacitors, battery holders do not hold up well in an oven at 230C.

    An update for everyone... I picked up a presto griddle and modified a harbor freight heat gun. I used a simple pci slot fan controller and a cooling fan out of an old xbox to replace the stock blower on the heat gun. Now I have a bottom preheater and a top reflow "wand". Just waiting on a 2000w thyristor-based voltage control from ebay.
    Cost of griddle: free from roommate
    Cost of Heat Gun : $12 from harbor freight +$5 for nozzles
    Cost of voltage control: $5 from ebay
    Thermometer with k-type thermocouple: $5 on ebay
    Works great on laptop boards, but am struggling on playstation 3, just reworking a junk mobo for practice (system controller is bad, matched to cpu from what I have read)
    The sony boards are really thick and dissipate alot of heat, was planning on reballing another console, but maybe a reflow for now(gotta get some kester 951) and some more practice.
