Attribute based specification,comparison and selection of electroplating system using MADM approach

The problem of electroplating selection has been of concern to users for many years. The selection process is becoming more and more difficult due to the availability of large variety of electroplating configurations and manufacturing plants/products. The methods proposed so far consider only physical parameters (thickness, hardness, adhesion, etc.). In order to have precise information about the selection process, the performance of electroplating plays a vital role.The objective of this paper is to propose a methodology by which selection of electroplating product/plant can be made easy. This selection procedure will help the user to select the system most suited for his operational needs. Moreover, the paper discusses how the electroplating suppliers, designers and maintenance personnel will also be benefited.The identification and codification of attributes based on n-digit alpha numeric code is presented here. The 3 stage selection procedure allows rapid convergence from a very large number of options to manageable shortlist of potentially suitable electroplating option using ‘elimination search’ based on a few pertinent attributes. Then the selection procedure ranks them by employing a multiple attributes decision making (MADM) method using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) approach. It helps the decision maker(s) to organize the problem to be solved, and carry out analysis, comparisons and ranking of the alternatives. Magnitudes of different attributes are used to generate parameters of the hypothetical ideal electroplating, with all the candidate electroplating compared and ranked. This ranking gives the best available electroplating for particular application. The methodology is presented with the help of illustrated example of gold plating, which shows that it can benefit the designers, users or manufacturers.     

MODULIGA: The LIGA process as a modular production method-current standardization status in Germany

The LIGA process combines X-ray lithography with electroplating and molding. It is a technique used worldwide for the fabrication of high aspect ratio microstructures. In Germany, this technique will be established as a production line to manufacture micro system devices. A project named (modular production method using the LIGA process) MODULIGA has the goal to link together the activities of the German LIGA centers Forschungszentrum Karlsruhe / Institut für Mikrostrukturtechnik, Karlsruhe (FZK/IMT), Institut für Mikrotechnik, Mainz (IMM) and Berliner Elektronenspeicherring-Gesellschaft für Synchrotronstrahlung, Berlin (BESSY). LIGA process steps will be standardized and interface specifications will be defined to establish a modular production method. Interface specifications are defined for masks, substrate and resist, exposure technology, development and finally electroplating. The standards are defined by testing criteria. The challenges and the current status of standardization will be described.     

APCP-150智能脉冲镀银电源的设计与研发

国产脉冲电镀电源通常采用手动方式调节参数,因此在设定参数之后,只能以单一参数的脉冲波形进行电镀;某些国外电镀电源虽然实现了程控,但也存在一定的缺陷．如脉宽调节范围较窄,脉冲频率不可调等。针对上述缺陷,对传统脉冲电源进行了优化设计。新设计的APCP-150型程序控制脉冲镀银电源主要基于程控技术和斩波技术,以大功率半导体器件为主开关器件。通过PLC输出不同频率的脉冲信号来进行控制,以实现各种不同工艺要求的电镀,并在镀银生产中减轻了工人的劳动强度,节省了工时。     

A linear optimization approach to the heterogeneous r-cyclic hoist scheduling problem

The cyclic hoist scheduling problem is encountered in electroplating facilities, when mass production is required. This class of problems is a branch stemming from the Hoist Scheduling Problem (HSP) where automatic hoist is used for moving electroplates through chemical baths. A repetitive sequence of moves is searched for the hoist in cyclic schedule. To minimize the cycle time of r different part-jobs, we propose a linear optimization approach. An illustrative example is given in order to show some feedback of our exact solving method. Afterward, two comparisons are presented: firstly, between a two 1-cycle homogenous schedule and a 2-cycle heterogeneous part-job and secondly, between 2-cycle and 4-cycle heterogeneous part-job. These comparisons show how, by considering r-cyclic scheduling, we can optimize the cycle length considerably and then the throughput rate of the electroplating line.

Inspecting mixed textured lens collar images using discrete Fourier transformation

Superficial and electroplating defects are the most commonly seen flaws on the lens collar. The former arose from cutter offset or chip winding during the cutting process, while the later occurred if the surface was stained with rough or foreign material during the electroplating process. Relying on human inspection to ensure quality of a lens collar was time consuming and accounted for occupational injury. Thus, implementation of automatic inspection technology became invertible in the mass production environment. Since the texture on the surface of lens collar was not only regular but also statistical, the system used image restoration based on discrete Fourier transformation (DFT) to detect defects embedding on those two types of textures.     

Application of UV depth lithography and 3D-microforming for high aspect ratio electromagnetic microactuator components

 This paper was presented at the Fourth International Workshop on High Aspect Ratio Micro-Structure Technology (HARMST) 2001 in Baden-Baden, Germany. For building high aspect ratio parts, using a combination of UV lithography and electroplating is a very promising approach. This paper describes investigations regarding the application of UV lithography and electroplating to fabricate high aspect ratio component parts of microactuators, such as coils and pole pieces. As resist materials, both novolac-based resists and photosensitive epoxy were investigated. The high aspect ratio photomasks were used as micromolds for electroplating coils and magnetic structures in micromotors. Received: 10 August 2001/Accepted: 24 September 2001
