Patent ID: 8146793

Claim:
A flux imprint apparatus for imprinting flux on a substrate, the flux imprint apparatus comprising: a support; and an array of pins mounted to the support, wherein each of said pins comprises: a shaft having a longitudinal axis, a distal end and a proximal end opposite to the distal end; a first tapered portion disposed on the longitudinal axis of the shaft, the tapered portion tapering from a first circumference to a second smaller circumference in a direction toward the proximal end of the shaft; and a second tapered portion disposed on the longitudinal axis of the shaft between said first tapered portion and the proximal end, the second tapered portion tapering from a third circumference to a fourth smaller circumference that meets and integrally forms with the second circumference of the first tapered portion; wherein the taper angle of the first tapered portion is in the range of 3 degrees to 6 degrees relative to the longitudinal axis and the taper angle of the second tapered portion is in the ramie of 2 degrees to 5 degrees relative to the longitudinal axis; wherein the taper angles of the first and second tapered portions are different; and wherein there is no non-tapered section between the first tapered portion and the second tapered portion.
