Hi, when they did the reflow with the south bridge chipset they took a heat gun and went arround the chip in circles. This is what I did with the broken apple motherboard. I covered the board in tinfoil and cut out the squares arround the gpu, cpu an

Thank you all for the great responses. We to looked at tne Mirtec before settling on the YesTech. I felt the machine software was better structured and organized and the system caught more faults on our "broken" board than the other system did (We

Hi, It was funny. The sight of 3 men standing around the microwave daring each other to push the start button, and then freaking out when the whole thing looked as though it was going to explode was funny. I guess you have to try these things! Tho
