Methods and devices using the compositions are also disclosed.
Claims13
A conductive composition, comprising:
- at least one metal;
- a solder or solder alloy;
- a resin;
- and
- a mono-acid hybrid comprising an unprotected, single reactive group at a first terminus and non-reactive groups elsewhere, the mono-acid hybrid having the following formula:
- wherein X equals 1 to 9 and R1 and R2 are each independently selected from the group consisting of H, C1-C6 alkyl groups, C1-C6 aliphatic groups, C1-C6 alkoxy groups, and C1-C9 aromatic groups.
