Hi,
I am not so sure that the automotive industry is at the forefront of
soldering technology--only 2 years ago one of the Detroit Big 3 had to recall
2 years worth of SUVs because 60/40 SJs on CEM-1 [!?] PCBs for the windshield
wiper controls under-the-hood failed well within the warranty period. CEM-1
not only grossly thermally expands, but swells on H2O-absorption, and the bad
housing design caused the PCBs to warp.
