Re: reballing temperatures
There is a big difference temperature wise whether you are attempting to re-flow the bga rather than remove it. Most lead free solders melting point is 217c , you say your temps are 230c this is a good temp for re flowing the chip
all that you have said should be given good results when removing the chip.
I think you may need to experiment more with your machine , first of all I would try another site close to the chip for the Tc and allow between 1-2mm away from the chip I own a jovy which is very similar in comparison to one of the ersa...Leave a comment:

Re: reballing temperatures
Could you give me more info on the flux you are using ,There are some excellent liquid fluxes out there but they all have different purposes. I think the problem you are relating to is you are trying to remove the chip to early and or there might not be enough even spread of the flux under the chip for the heat dispensation . Could also be the placement
of the TC on the board are you putting some flux around the TC. There are a number of reasons why this could happen , but we will accomplish this in the endLeave a comment:
