摘要： The invention relates to a device for measuring the shearing action in the core of a sandwich structure, for instance a hull. The device comprises a sensing means, e.g. a cylindrical rod, and a measuring instrument. The rod is adapted to be inserted into a cylindrical hole which is bored in the hull preferably perpendicular to the surface thereof so as to extend a distance into the core and which has a diameter corresponding to that of the rod. By means of the measuring instrument, an angle between the rod and a reference plane is measured, which is determined by three points on the surface of the hull or the change of this angle when the hull is subjected to a change in load. This angle can be converted into a measure of the current shearing load.

摘要： A method and art apparatus are proposed for inspecting solder balls on a BGA (Ball Grid Array) package, which are capable of rejecting defectively-bonded solder balls while allowing properly-bonded ones to pass therethrough. The proposed method and apparatus are characterized by the use of a rotatable disk having a plurality of flaps arranged at equal angular intervals along the perimeter thereof, and which is capable of being rotated in steps if a force greater than a preset threshold torque is being applied tangentially to any one of the flaps. The threshold torque is set to be equal to or less than the shear-resistant strength of a properly-bonded solder ball but greater than the shear-resistant strength of a defectively-bonded one. During an inspection procedure, the BGA package is moved toward the rotatable disk to allow each solder ball to push against one of the flaps on the rotatable disk. If a solder ball is a properly-bonded one, it would be capable of pushing open the flap and therefore passing through the inspection procedure; otherwise, for a defectively-bonded solder ball, it would be rejected and broken apart from the BGA package by the flap. Therefore, as the entire BGA package has undergone the inspection procedure trough the rotatable disk, all properly-bonded solder balls would remain in position over the BGA package, while all defectively-bonded ones would be removed.
摘要翻译：提出了一种用于检查BGA（球栅阵列）封装上的焊球的方法和技术装置，其能够拒绝有缺陷粘合的焊球，同时允许适当粘合的焊球通过。所提出的方法和装置的特征在于使用具有沿着其周边以相等的角度间隔布置的多个翼片的可旋转盘，并且如果正在施加大于预设的阈值扭矩的力，则能够以步进旋转与任何一个襟翼切向。阈值扭矩设定为等于或小于适当焊接的焊球的抗剪切强度，但大于缺陷接合的焊球的抗剪切强度。在检查过程中，将BGA封装移向可旋转盘，以允许每个焊球推压在可旋转盘上的一个襟翼上。如果焊球是合适的焊球，则能够打开挡板并因此通过检查程序; 否则，对于缺陷焊接的球，它将被挡板从BGA封装中排除和分离。因此，由于整个BGA封装经过可旋转盘的检查程序，所有适当粘合的焊球将保持在BGA封装上的位置，而所有有缺陷接合的焊球都将被去除。

摘要： The present invention provides an apparatus and a method to apply a load to an adherend, which is bonded to a substrate, to allow an accurate measurement of the bond between an adherend and substrate. The strength of the bond is tested by shearing the adherend from the substrate and measuring the force per unit area required to fail the bond. This is accomplished by positioning a crosshead at the base of the adherend and applying a load, which is parallel to the surface of the substrate against the base of the adherend. The strength of the bond is the force per unit area required to shear the adherend from the substrate. The accuracy of the measurement is enhanced by minimizing the surface area of the crosshead that is in contact with the substrate and by ensuring that the adherend is not fractured during testing. Fracturing and deformation of the adherend is limited by using a notch to test with rather than a straight chisel. The present invention is configured to load the adherend such that the strength of the bond may be measured accurately.

摘要： A method of measuring shear friction factor between a workpiece material and a forming tool through a backward extrusion process. The method includes steps of: positioning the workpiece material at a groove previously manufactured on the forming die by turning; pressurizing the workpiece material to form an extruded product by pressure of a downwardly moving punch; forming tip on the extruded end of the extruded product; measuring an external diameter of the extruded product and a diameter of the tip, and obtaining a perpendicular distance by subtracting the diameter of the tip from the external diameter and dividing the subtracting result by two; and acquiring shear friction factor by calculating predetermined coefficients and a normalized perpendicular distance non-dimensionalized by thickness value of the extruded product. The thickness is defined as an interval between the external diameter of the extruded product and an external diameter of the punch.

摘要： A nanoindentation apparatus is used to measure adhesion strength of a hard, thin film to a soft substrate. A variably increasing load is applied to the indenter tip. The indenter tip penetrates into the thin film at a first penetration rate and causes the thin film to sink into the substrate thus causing a tensile stress at the film substrate interface. At a critical value of the applied load, the stress at the interface exceeds the delamination value, and the thin film partially delaminates from the substrate. This causes the indenter tip to sink into the softer substrate at a sudden second, higher penetration rate. A sensor detects the applied load and the indenter tip penetration depth at this point. A computer flags the critical value of the applied load that corresponds to the increased penetration depth rate at the point of delamination of the film. The computer then calculates the critical stress required for delamination and the adhesion strength between the film and the substrate from the critical value of the applied load. The depth sensing indentation technique measurement may be carried out on a thin film integrated test element so as not to damage the rest of the thin film. The method allows non-destructive in-situ adhesion strength measurements for thin films and microelectronic devices.

摘要： A portable device for measuring the shear properties of a material specimen under applied dynamic circumferential forces against the specimen perpendicular to a longitudinal axis of said specimen. The device may further apply a dynamic force against an end of the specimen. The device includes clamps that hold the specimen at its proximal and distal end, wherein the circumferential force applied to the specimen is affectively applied between the two clamps. The temperature of the specimen may be held constant by controlling the temperature within an environmental chamber through the use of a closed loop PID control system. The force against the specimen is dynamically loaded by a dynamic load reaction frame consisting of a shear load actuator and load reaction structure. A microprocessor-based controller operates the dynamic load reaction frame under closed loop control. The microprocessor-based controller may be servo controlled, utilizing feedback from either a load transducer or either or both of two linear displacement transducers.
