使用埋入射出成形製程對於手機顯示器模組強度改善之研究

Abstract

本文係研究將塑膠承載框與金屬背板結合，以增強模組強度，而先以有限元素法模擬確定埋入射出成型之模組強度確實會比傳統組裝式模組強度高，以確認研究之方向正確，再實際以實務製作，也就是金屬背板先以沖壓製作成型及再將金屬背板放進射出成型之模具中，以埋入射出成形技術將兩者結合，接而以2D量床量測重點尺寸，確認製作成品之外觀尺寸達到設計規格尺寸公差，後續再以四點彎折治具進行彎折測試，並與傳統組裝方式之模組進行強度之比較，以確認埋入射出成形製程確實會較傳統方式得到較高的模組強度。

Housing frame combine with base metal will be studied in this article for module strength enhancement. The base metal will be formed by punching first, then put the sample into the injection machine to form the housing frame. All the dimensions will be checked by 2D measurement machine first to make all the dimensions can meet design tolerance and 4 point bending will test to verify the module strength. Also, the conventional module will test for comparison to make sure the new method (Insert molding) will have better strength than the conventional one. FEM will also simulate the insert molding module strength to check the experiment direction.
