Abstract
A composition for producing a printed circuit board is provided. The composition includes a polyamic acid having one or two crosslinkable functional groups introduced at one or both ends thereof, a liquid crystal polymer (LCP) or a liquid crystalline thermoset (LCT) oligomer, and an organic solvent. Therefore, the composition can be used as a material for next-generation boards that are becoming gradually lighter in weight and smaller in thickness and size. Further provided is a printed circuit board produced using the composition.
Claims14
A composition for producing a printed circuit board, comprising a polyamic acid having one or two crosslinkable functional groups located at one or both ends thereof, a liquid crystal polymer or a liquid crystalline thermoset oligomer and an organic solvent wherein the polyamic acid has a structure represented by Formula 1:
- wherein A is represented by Formula 2:
- in which X is a tetravalent aliphatic or aromatic organic group and Y2 is a divalent aliphatic or aromatic organic group, Z1 and Z2, which are identical to or different from each other, each representing a monovalent crosslinkable functional group having at least one carbon-carbon double bond, Y1, which is identical to or different from Y2, represents a divalent aliphatic or aromatic organic group, and n is an integer from about 1 to about 1,000, provided that when n is 2 or greater, the repeating units A are the same or different.
A film produced by solvent casting a composition for producing a printed circuit board, the composition comprising a polyamic acid having one or two crosslinkable functional groups located at one or both ends thereof, a liquid crystal polymer or a liquid crystalline thermoset oligomer and an organic solvent wherein the polyamic acid has a structure represented by Formula 1:
- wherein A is represented by Formula 2:
- in which X is a tetravalent aliphatic or aromatic organic group and Y2 is a divalent aliphatic or aromatic organic group, Z1 and Z2, which are identical to or different from each other, each representing a monovalent crosslinkable functional group having at least one carbon-carbon double bond,
- Y1, which is identical to or different from Y2, represents a divalent aliphatic or aromatic organic group, and n is an integer from about 1 to about 1,000, provided that when n is 2 or greater, the repeating units A are the same or different.
