Solder ball shear testing is one of the more common tests performed on the welding strength tester, Used to test the bonding strength between the tin ball and the substrate after the ball is planted

TRY PRECISION Multifunctional Push-pull Tester can conduct bump shear testing in a production testing environment to verify the reliability of products.

TRY PRECISION Multifunctional Push-pull Tester can be used to conduct cold bump pull testing, during which, the tinned ball are held by tweezers and pulled vertically from the equipment or base plate.

Time-dependent deformation is an important failure mechanisms. The change in the size of material under static load is called creep, whose measurement is important for welding, polymers, and adhesives, because large strains occur over time and strain rates are very temperature sensitive.

The conventional chip shear testing involves the accurate landing of the loading tools and its positioning over the base plate. This testing is similar to the standard solder ball shear testing.

The probe is connected to the solder ball or solder plate in way of heating and then cooled down quickly, so that the probe is pulled up vertically from the solder ball or solder plate to detect whether the pad pit cracks in surface mount and the printed circuit board assemblies.

Aluminum Tape Stripping Test can replace aluminium tape tensile test, which is mainly used to test aluminum interconnection in microwave, high frequency, power supply, automotive, hybrid, and solar equipment.

TRY PRECISION Multifunctional Push-pull Tester is extremely flexible and can carry out tensile testing of aluminum tapes of different dimensions, wire heights and widths, through tweezers, pull plier and traditional pulling hooks.

With regard to the special samples required by customers, TRY PRECISION has launched a vector thrust module with fully automated devices, that is, we do not need to rotate fixtures and samples but can do the test in any direction only by rotating the sensor direction of the module.

The principle of the basic wire testing is to place a crochet hook under the wire and pull it up vertically along the Z-axle direction until the welding is broken (destructive test) or reaches a predefined force (non-destructive testing).

TRY PRECISION Multifunctional Push-pull Tester can perform press-down testing on samples by the dedicated fixtures and down pull module, such as the usual crystal break test.

TRY PRECISION Multifunctional Push-pull Tester also supports brittle fracture test, because the strength of brittle materials (such as silicon and glass) primarily depends on the microcracks or surface defects such as scratches and gaps. In these brittle materials, the high pressure at the crack top cannot be relieved by the plastic flow, so even very small defects can result in low fault load.

TRY PRECISION Push-pull Tester provides fatigue test for a range of different applications (including the evaluation of joint life in test sockets). The cyclic strain can be applied repeatedly, and the test software provides a variety of fatigue tests for determining fatigue life.

The micro material testing systems of TRY PRECISION Push-pull Tester has a variety of tools that can compress the loads on small samples that are also difficult to clamp and the applied force can be less than 0.01N.

The micromaterial test system of TRY PRECISION allows components to bend and twist with the specially designed work fixtures (which can convert our standard linear driving force into rotational power).

Testing the mechanical integrity of welding is an important aspect for ensuring the production quality, but testing copper interconnection brings some challenges to the traditional shear testing. In order to overcome these problems, TRY PRECISION in which a specialized tweezer is used to hold the solder so that a vertical load is applied to the solder to have the tensile test.

TRY PRECISION Push-pull Tester supports forceps stripping strength testing, as an alternative to tensile test to verify adhesion or weld strength. The stripping angle can be controlled by software to be 90° with welding. Before the testing, please carefully remove any preload at the welding caused by the proximity of pliers and clamping of materials, so as not to affect the test results.

The primary purpose of introducing the vector tension testing is to apply a tension with programmable angle to the leads on MBGA equipment, thus preventing the pull hook from sliding to the narrow part of the welding joint.
TRY PRECISION Vector Tension Testing utilizes a software-controlled angle to conduct programmable controlled tension testing that eliminates the need for a variable-angle work stand.

The wedge shear testing combines the relatively large force and ultra-high precision shear height, requiring automatic press touch of loading tools to realize high precision step back in the Z direction.

TRY PRECISION Push-pull Tester can provide column tension testing (maximum: 200kg) for the crystal grains that remove the package or lead frame, which is suitable for horizontal and vertical column tension methods.

There are various challenges when testing the surface of overhanging crystal grains. Due to the thin welding spacing between the crystal grains and low contour line, and the possible surface deflection during the step back period required for landing and setup of loading tools, the solder ball shear testing is very difficult to carry out.
Step back is defined as the distance between the tip of the loading tool and the surface adjacent to welding. The complex situation of possible deflection during the step back period required by the landing and setup of loading tools can be overcome if we use the oscillating loading tools which combine with the advanced software for controlling operation sequences during the bond testing period.

Standard welding zone shear testing (up to 50 mm/s) is performed on the wide loading tool incorporating a high-speed XY working platform, that engages synchronized loads and applies to a complete round of welding. During the entire testing, the test results of the first round of welding create a stripping effect for the next round of welding. During the test, the intelligent loading tool and stepping back system are used to actively control the shear height, while the fixture is used to adjust the planarity and coplanarity of samples.
