Oh...wait a minute... that will violate LEAD free rules... I'm screwed now.. |O --- End quote --- Tungsten or tantalum works better that lead --- End quote --- Yes that will succeed 100% of the times in getting your baggage stopped and opened by TSA or whoever in order to check that the lump of metal is not a battery bank or something :-DD |

If you really need the CPLD to withstand strong x-rays you can get the space rated ones, they shoul be able to shrug off anything an airport throws at them with ease. It won’t be neither cheap nor easy to get |

Based on the inputs, it looks like an aluminum heat sink over the CPLD may be the cheapest solution for the problem. They are easy to buy and install.. Not sure of Zinc sheets, will check if they are available online. |
