Non-Contact Piezoelectric Ceramic Micro Droplet Jetting Dispensing Technology And Precision Research

With the advent of the era of industry 4.0(Industry 4.0),human beings have ushered in the information system(CPS)as the basis for the production of highly digital,networked,machine self-organization as a symbol of the fourth industrial revolution.Consumer electronics manufacturing industry as the traditional labor intensive industries,and the fourth industrial revolution as the basic industr y,both to meet the consumer electronics industry with the rapid development of science and technology progress,but also to meet the consumer electronics industry's rapid update Characteristics,is bound to face the challenge of industrial upgrading and control costs,enterprise competition is the fundamental,more is to earn profit by controlling costs.The global economic integration process,the whole world industrialization production into a more refined division,in many industries into the era of low profit,light on a single product itself profit,insufficient to make up the cost of pressure,only through large-scale production,can bring profit growth point,Therefore,it 's imperative to control costs,cost can be divided into raw materials,production,logistics,warehousing,sales and other links,production as the most important part of the consumer electronics industry,is bound to need to improve production process,improve the competitiveness of their products.This has led many companies to improve the production process,improve the production efficiency of the impulse and demand.As an important part of the production process of consumer electronics manufacturing industry,electronic packaging,with the need of scientific and technological progress and the need to control costs,but also in constant progress,which is a branch of the field of electronic packaging,dispensing industry,is an important complement to the field of electronic packaging.It is mainly of electronic products to adhesive,potting,encapsulating,sealing,underfill,confining effect of dam,conformal coating,conductive,welding.The non-contact piezoelectric ceramic micro jetting technology,as a new dispensing technology,completely subvert the traditional dispensing technology,electronic packaging to achieve more efficient and stable precision dispensing mode,improve the traditional dispensing mode of various shortcomings and disadvantages,from the dispensing efficiency,dispensing accuracy,leading dispensing industry entered a new level.In this paper the dispensing industry non-contact pressure piezoelectric ceramic micro injection dispensing technology has carried on the analysis elaboration,and has carried on the analysis and research on the precision.Mainly from the non-contact type pressure piezoelectric ceramic micro injection dispensing technology for consumer electronics manufacturing dispensing velocity(dispensing efficiency),dispensing accuracy(dispensing repeatability,dispensing accuracy)of great significance and value to explore,respectively through the motion system,the end of the execution,flow,visual system were analyzed and discussed.Due to the large number of factors affecting the dispensing technology point accuracy of gum(dispensing repeatability,dispensing accuracy),respectively,by dispensing platform geometry,assembly,driving and positioning,work load factor influence,dispensing valve supplying pressure,fluid channel,valve time(piezoelectric frequency reciprocal),hit a needle selection,selection of nozzle,dispensing height factors influence,of electronic adhesive viscosity changes,the changes of environment factors to study and analyze.Specific method is to pressure non-contact technique,electric ceramic technology,micro injection technology as the background,using non-contact piezoelectric ceramic micro droplet jetting dispensing valve,through the use of polyurethane adhesive and epoxy resin adhesive,acrylic adhesive electronic adhesive,design different experimental methods(One is traditional dispensing technology and piezoelectric ceramic micro droplet jetting dispensing technology comparative experiments,this pressure piezoelectric ceramic micro droplet jetting dispensing technology is highly efficient.Second pressure piezoelectric ceramic micro droplet jetting dispensing technology using different adhesive,different dispensing parameters of the experimental setup,described the non-contact pressure piezoelectric ceramic micro injection repeatability and accuracy of the dispensing technology),obtain a lot of valuable experimental data,using EXC EL orthogonal experimental table was used to analyze the data,find the core elements of the real impact of dispensing accuracy.And with the bad phenomenon of non-contact piezoelectric ceramic micro jetting technology to analyze and study,make the world 's leading non-contact type pressure piezoelectric ceramic micro injection dispensing technology and precision research of great significance reflected.It can help consumer electronics manufacturing industry production process understanding,acceptance,make good use of this technique,let consumer electronics manufacturing industry to improve production technology,improve production efficiency,improve the quality of production.Truly reduce production costs,improve market competitiveness,to provide global customers with good,excellent,perfect high quality consumer electronics products.
