PDM technology and its application in SMT product assembly production Li Chunquan Electronic Mechanical Engineering. 2000, 3.7, 203 PDM technology is applied to the circuit surface assembly technology SMT product assembly system and its application prospects are prospected. Refer to Tang Jun Electronic Mechanics, g. 2000, the issue of soldering resistance technology in large area soldering. With the development of large area soldering technology, corresponding requirements have been put forward for soldering resistance technology. In this paper, based on the study of the mechanism of solder mask, the special characteristics of solder mask removal in large area soldering are analyzed. The simple process flow of solder mask is introduced; finally, the Application and results. Participate in the assembly process of radar component board 0016921 Filter surface brazing joint brazing solder selection 0016318 Electronic Information and Communication Society Technical Research Report Electronic Devices and Materials Electronic Information and Communication Society Technical Research Report Electromechanical Devices, 99 Electronic Information and Communication Society Technical Research Report Electromechanical Device 99 0940 Pressure Processing and Casting Process B 0 Controlled Centrifuge Pouring Closed Loop Speed ​​Control System Journal Yan Bing Rapid generation of parts model based on history Wu Junjun Machinery and a new direction method of geometric elements were proposed and a history based The relationship between the modeling parameters and the shape in the parameterization process, and on this basis, a rapid generation method of the part model based on history is formed. Finally, the evaluation of the method shows the effectiveness of the method.
