Widely used in the plastic molding industry, it is a well-known software for mold flow analysis. Professionals in related fields are likely familiar with its applications. Besides its basic injection molding functionalities, MOLDFLOW offers various modules tailored for different scenarios and processes. This article will not discuss the commonly known plastic injection molding simulation. Instead, we will focus on the \"Microchip Packaging Module,\" a very important component of the software. This overview aims to provide newcomers with a basic operational workflow, serving as a useful reference for those beginning their learning journey.<\/p>\n\n\n\n<p>The \"Microchip Packaging Module\" is used to simulate the process of plastic encapsulation of microchips. It can simulate situations such as encapsulant filling, substrate deformation, and wire deformation. This helps the electronic packaging industry in design and process evaluation.<\/p>\n\n\n\n<p>The analysis content of microchip packaging includes filling, packing, die pad shift, and wire sweep. Therefore, in addition to simulating the filling process, simulating the shift of the substrate and wire is a major focus. To achieve this, the model must be divided into three objects for import: the encapsulant, the die pad (substrate\/lead frame), and the wire.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"236\" src=\"https:\/\/taichungbro.com\/wp-content\/uploads\/2024\/07\/1-flowchart-1024x236.png\" alt=\"1-flowchart\" class=\"wp-image-2385\" srcset=\"https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/1-flowchart-1024x236.png 1024w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/1-flowchart-300x69.png 300w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/1-flowchart-768x177.png 768w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/1-flowchart-1536x354.png 1536w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/1-flowchart-18x4.png 18w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/1-flowchart-600x138.png 600w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/1-flowchart.png 1563w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\u532f\u5165\u7269\u4ef6\">Import Objects<\/h2>\n\n\n\n<p>The encapsulant and die pad must each be a single object. For the die pad, the import requirements depend on the simulation detail needed. If the focus is solely on the substrate, then just the 3D substrate model needs to be imported. For a more comprehensive simulation, you can import a combined 3D model of the substrate and lead frame, or even include the heat sink if necessary. However, the more objects combined, the more complicated it becomes to specify different materials, as this requires setting mesh surfaces individually. In MOLDFLOW, the wire is defined as lines rather than 3D objects, and there can be multiple wires.<\/p>\n\n\n\n<p>It is recommended to save the encapsulant and die pad as \"STP\" files for import, while the wire should be saved as line elements rather than 3D, and thus imported as \"IGES\" files. It is advisable to import each object separately into a new study, process the surface mesh, and then combine them into the same study afterward.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"150\" src=\"https:\/\/taichungbro.com\/wp-content\/uploads\/2024\/07\/2-function-list-1024x150.png\" alt=\"2-function list\" class=\"wp-image-2386\" srcset=\"https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/2-function-list-1024x150.png 1024w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/2-function-list-300x44.png 300w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/2-function-list-768x112.png 768w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/2-function-list-1536x225.png 1536w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/2-function-list-18x3.png 18w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/2-function-list-600x88.png 600w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/2-function-list.png 1634w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" width=\"658\" height=\"353\" src=\"https:\/\/taichungbro.com\/wp-content\/uploads\/2024\/07\/3-Dual-Domain.png\" alt=\"3-Dual Domain\" class=\"wp-image-2387\" style=\"width:594px;height:auto\" srcset=\"https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/3-Dual-Domain.png 658w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/3-Dual-Domain-300x161.png 300w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/3-Dual-Domain-18x10.png 18w, https:\/\/www.taichungbro.com\/wp-content\/uploads\/2024\/07\/3-Dual-Domain-600x322.png 600w\" sizes=\"(max-width: 658px) 100vw, 658px\" \/><figcaption class=\"wp-element-caption\">\u25b2 Import and select Dual Domain<\/figcaption><\/figure>\n<\/div>\n\n\n<p>It is recommended to first assign properties to the objects.

It is recommended to turn off CAD elements to ensure the gate is placed on the node.<\/p>\n\n\n\n<p>3.The mechanical properties of the selected material are not specified or invalid, and there are issues when reading the stress analysis results:<br>This is typically due to the lack of specified parameters in the material library. Please check and ensure the necessary properties are defined.<\/p>","protected":false},"excerpt":{"rendered":"<p>MOLDFLOW is a plastic injection molding simulation software developed by Autodesk. Widely used in the plastic molding industry, it is a well-known software for mold flow analysis. Professionals in related fields are likely familiar with its applications. Besides its basic injection molding functionalities, MOLDFLOW offers various modules tailored for different scenarios and processes. This article will not discuss the commonly known plastic injection molding simulation. Instead, we will focus on the \"Microchip Packaging Module,\" a very important component of the software. This overview aims to provide newcomers with a basic operational workflow, serving as a useful reference for those beginning their learning journey.<\/p>","protected":false},"author":2,"featured_media":2384,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[49],"tags":[159,186,190,187],"class_list":["post-2381","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-software-application","tag-ic","tag-moldflow","tag-190","tag-187"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.taichungbro.com\/en\/wp-json\/wp\/v2\/posts\/2381","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.taichungbro.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.taichungbro.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.taichungbro.com\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.taichungbro.com\/en\/wp-json\/wp\/v2\/comments?post=2381"}],"version-history":[{"count":0,"href":"https:\/\/www.taichungbro.com\/en\/wp-json\/wp\/v2\/posts\/2381\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.taichungbro.com\/en\/wp-json\/wp\/v2\/media\/2384"}],"wp:attachment":[{"href":"https:\/\/www.taichungbro.com\/en\/wp-json\/wp\/v2\/media?parent=2381"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.taichungbro.com\/en\/wp-json\/wp\/v2\/categories?post=2381"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.taichungbro.com\/en\/wp-json\/wp\/v2\/tags?post=2381"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
