Solder Paste—Tack Test
ScopeThis test is to determine the ability of a printedpattern of Solder paste to retain a probe placed in the solderpaste by measuring the force required to separate the probefrom the paste. Time between printing and probe placementare progressively increased to simulate variables in a manu-facturing Applicable Test SpecimenA representative sample of this pasteshould then be printed out, using a stencil, onto clean plain-glass slides. At least six paste deposits should be printed perrequired time data-point. The final deposits must be circular, mm in diameter and mm thick. Mark the test speci-men in a suitable manner to identify the sample and the timeafter printing when tackiness is to be measured.
