The thickness of solder required to circumvent a gold-embrittlement
problem, increases rapidly with increasing gold thickness. Dwell times in
the Levelling and/or Fusing process will have to be increased, temperatures
and other parameters, that will pose a detrimental effect on the circuit
laminate, will have to be adjusted to increase the thickness well above 1/4
mil.
