Hi Takeshi! I will modify my reballing machine project, change the IR lamps by IR ceramic resistors.
On the top will be one ceramic resistance(70mm x 70mm). On tho bottom I will put 4 resistances (120mm x 120mm each). I will produce covers to top and bottom, the top cover wil be the same area from chip and the bottom cover will be the same area from motherboard.
What do you think about that?
