Hello everyone
Today, I face a very weird problem
I have my custom ESP8266 board based on ESP 12. I have successfully upload and run the code with it then I decide to make 500 boards with PnP and reflow oven at the small SMT factory. When I received the board, the soldering quality looks fantastic but when I try to upload the code, more than half of the boards seem to be dead
Nothing show up to serial monitor after I restart the ESP8266 (the working board did). Uploading using arduino IDE and Node MCU flasher also not working (time out waiting for packet head...)
I swap the Esp chip with the working one and everything is fine, so the brand new chip from reel is dead (dont know before or after soldering)
Please tell me how can I check if the chip still can be revived, I dont think that the reflow process killed the chip
thanks alot
sorry for my bad English!
