At present, the short-beam shear test
, the V-style notch beam shear test
, and the double notch shear test
were mainly used in the shear strength measurement of laminated board.
The obligatory parameters for the direct shear test
are testing temperature, loading speed, dimensions of samples, gap between fixation and shearing rings.
More than 80 data has been obtained from existing sources of RC beam shear test
results covering a wide range of beam properties and test methods.
The most that can be said about a shear test
is that the greater the force required to shear the component, in theory at least, the better and stronger the solder joint.
As a result, a shear test
and a fusion evaluation test were found to be the best accelerated tests for integrity assessment.
The single lap shear test
(ASTM D 1002-72) is widely used to determine bond strength and quality.
Atotech global experts will join this event and present the following papers at SMTA International technical conference Tuesday, September 19, 2:30 pm to 3:00 pm, Substrates / PCB Technology Session: The impact of deposition thickness on high speed shear test
result specifically related to electroless palladium and semi autocatalytic goldThursday, September 21, 8:00 am to 8:30 am, Advanced Packaging Technology Session: Fine line through hole copper filling in VCP for next generation packaging
Interface friction angle was determined by conducting direct shear test
For both EPIG and ENEPIG processes, the solder joint reliability as determined by a high speed shear test
was examined, with the deposits as-plated and after heat treatment.
The teeth in both groups were embedded individually in acrylic placed in rubber moulds using a mounting jig so that the labial surfaces would be parallel to the applied force during the shear test
data were averaged for the two subreplicates for each beam, and then data for treated and untreated beams were compared using paired t tests at [alpha] = 0.
