[Hackrf-dev] Jawbreaker reflow problems

[Graham Cottew]

Hi Adam

I have tried (unsuccessfully) to hand reflow around the RF area if my jawbreaker to fix a deafness problem on receive. 
I would be very happy to let you have a go at my board in the oven anytime :-)

I needed to replace the SPI flash chip as well as it had failed but doing that by hand was straightforward.

Accordingly, we'd like to reflow in an oven, but to do so we need to know the correct profile - is that something we can get from the original manufacturing order?
