  • Control of flux by ink stop line in chip joining
    Patent number: 6904673
    Abstract: Ink jet printing apparatus is employed to form a non-polar ink stop line around a chip site on the polar surface of an organic laminate substrate. The non-polar ink stop line acts to confine polar liquid flux from spreading after application of the flux to the chip site prior to chip joining. Excessive flux spreading results in insufficient flux being present at the chip site for the formation of good electrical connections during solder reflow upon chip joining.
