In this paper, installation automatic die bonding machine and optimization parameters were studied in die attach process for integrated circuit (IC) packaging. Die attach process is one that is very important IC packaging manufacturing. This process is attaching a die or chip take to leadframe or substrate using die bonding machine. After installation machine, the parameters of equipment...
The Rockwell hardness test penetrated depth normally not more than 0.260 mm. Using commercial load cell cannot achieve the force calibration proposed. For these reasons, the high stiffness load cell fabrication, HSL is subject. Its obviously advantage is deformed less than 0.020 mm at 150 kgf maximum load applied. The HSL prototype was designed in concept of direct compression then confirmed...
The nest bar, or length bar, is a standard bar with two kinematic seats. The center-to-center length between seats is used as standard length for detecting geometric and thermal errors of an articulated arm coordinate measuring machine (Arm CMM) according to the guidance of ISO 10360-12:2016. Each seat shall be a kinematic seat where the center of the ball probe may be repeatedly positioned in...
The industrial processes for high-precision engineering and metrology require the fine quality control of products. The precision of rotary spindle is also required to enhance the accuracy of spindle motions to the nanometer and sub-µradian levels. Spindle measurements by conventional methods will have contributions from the spindle motion error and the form error of the target artifact. In...
The development of a measurement system for non-destructive testing of magnetic force microscopy (MFM) probes is discussed in this paper. Typical MFM probes are characterized by equipped in a conventional atomic force microscope (AFM). Test parameters are the resonance frequency of MFM probes and its response to a magnetic stray field from a standard test sample. This procedure involves...
