Research Of Time Quota Making Method And Application In PCB

Print Circuit Board(PCB)known as the "mother of electronic products" is the support body of electronic components and realizes the electrical connection of electronic components.It plays a very important role in various electronic products.As a typical industry that adopts multi-variety and small-batch order production,its products are characterized by a wide variety of products,small batch size and complex process flow,which makes it difficult to develop standard working hours.It is impossible to adopt the empirical estimation method,and it is also difficult to apply the traditional working hour quota setting method.This causes great difficulties to the production planning,product quotation,cost accounting and other aspects of the enterprise,which seriously hinders the enterprise’s rapid,efficient and more refined management objectives and restricts the development of the enterprise.Therefore,it is necessary to establish a set of accurate and efficient standard working hour formulation method for PCB enterprises.By analyzing PCB product features and process flow,this paper points out the low precision and low efficiency of working hour quota in this kind of enterprise,and expounds the importance of reasonable and efficient working hour quota method for enterprise production management.In view of this situation,this paper puts forward the method of making PCB working hour’s quota by applying typical working procedure method.In this method,the principle of product similarity is taken as the basis and the measured time data of enterprises as the basis.First of all,through the field investigation of PCB product process,reasonable selection of typical processes;Secondly,the influencing factors of typical processes of PCB products were analyzed and collected,and the correlation model between typical process hours and influencing factors was established.According to the correlation analysis results,Pearson significantly extracted the characteristic factors affecting working hours.Then,regression analysis was used to build the model of key process processing time,and the model was compared with the standard measured values.Finally,the software engineering method was used to develop and design the PCB standard working hour system according to the processing time model developed by the typical working procedure,and the working hour system was applied to the actual production of the enterprise,effectively improving the efficiency and accuracy of the time quota of enterprise A.
