    Is it possible that heat damage just the Bluetooth part on the chip?




      Currently I designed a new board for the PSOC4 BLE chip. I demounted my chip from its previous board to the new one. The chip package is QFN and this time took me couple of times to mount it correctly on the new one. Although the chip was functional, I could not recognize it anymore. Then again, I demounted it and mounted on the previous board. The result was the same.

      Is it possible that heat ruin the connectivity? I know that the antenna is mounted correctly (when I measure its resistance with the ground, it is less than 2 ohm and almost short circuited)

      And in advanced, if the answer is yes, what is the suitable time of heating and the temperature?
