Claims20
A solder mask formulation, comprising:
- a liquid photo imageable solution;
- and
- a solution of functionalized diamondoids, wherein the functionalized diamondoids include a diamondoid having an acrylate moiety attached thereto, and wherein the acrylate includes a diacrylate.
A solder mask formulation comprising:
- a photoinitiator representing approximately 0% to approximately 30% by weight of the solder mask formulation;
- a functionalized diamondoid solution representing approximately 10% to approximately 50% by weight of the solder mask formulation, wherein the functionalized diamondoid solution comprises functionalized diamondoids, wherein the functionalized diamondoids include a diamondoid having an acrylate moiety attached thereto, and wherein the acrylate includes a diacrylate;
- an ether representing approximately 10% to approximately 30% by weight of the solder mask formulation;
- an aromatic representing approximately 0% to approximately 10% by weight of the solder mask formulation;
- a sulfate representing approximately 10% to approximately 30% by weight of the solder mask formulation;
- an acetate representing approximately 0% to approximately 10% by weight of the solder mask formulation;
- and
- one or more acrylates each representing approximately 1% to approximately 30% by weight of the solder mask formulation.
