Abstract
A method for depositing a material to join two surfaces of an electronic assembly includes determining, using dimensions of a pad area of a substrate, a deposition pattern for the material that extends across the pad area of the substrate. The method further includes creating a tool to deposit the material in the deposition pattern that extends across the pad area of the substrate.
Claims10
A substrate of an electronic assembly comprising:
- a material in a deposition pattern within a pad area of the substrate, the deposition pattern comprising an array of discrete domains of the material that extends across the pad area of the substrate with regular spacings of about 0.076 to about 0.203 millimeters (mm) between the discrete domains, the deposition pattern comprising the array of discrete domains has a tangency with respect to an edge of the pad area of about 0.025 mm to about 0.127 mm.
