What about repairing your old graphics card, gaming machine or laptop with your own BGA Rework Station made from old stuff? You can reuse your old halogen heater to create a preheater for your BGA Rework Station, an arm from an old desk lamp in order to hold and move the top heater, aluminum curtain rails to hold your circuit boards, shower spiral cable to hold the thermocouples and an Arduino board as a PID temperature controller!First of all, what a BGA Rework Station is? Modern IC chips (CPUs, GPUs, etc.) do not have legs but a ball grid array (BGA) of solder balls. In order to solder/desolder a chip like this, you need a machine that heats up the IC until ~230 Celsius without stretching the circuit board or produce thermal shock to the IC chip. That’s why you need a temperature controller. These machines cost from 400$ to …
