流體點(diǎn)膠技術(shù)是以一種可控的方式對(duì)膠液進(jìn)行精確分配的過程。微電子封裝中貼片、晶片打標(biāo)、底部填充等重要過程都需要流體點(diǎn)膠技術(shù)的支持,以實(shí)現(xiàn)精確穩(wěn)定的電子封裝。為了適應(yīng)微電子技術(shù)的發(fā)展需求、提高生產(chǎn)效率及點(diǎn)膠質(zhì)量,點(diǎn)膠技術(shù)正逐漸不可避免的由接觸式點(diǎn)膠技術(shù)向非接觸式點(diǎn)膠技術(shù)轉(zhuǎn)變。本文對(duì)流體點(diǎn)膠技術(shù)進(jìn)行了綜述分析,并設(shè)計(jì)了一種基于壓電陶瓷驅(qū)動(dòng)的噴射式點(diǎn)膠閥。首先,分析影響流體噴射過中液滴形成的主要因素,分析了膠滴形成機(jī)理。根據(jù)質(zhì)量守恒定律和動(dòng)量守恒定律對(duì)粘性不可壓縮流體的層流運(yùn)動(dòng)建立了控制方程,利用VOF模型追蹤噴射過程中液體表面在空氣中變化并形成液滴的過程,并根據(jù)連續(xù)表面力法(CSF)描述氣相與液相間的表面張力作用。分別分析了供料壓力、撞針運(yùn)動(dòng)、表面張力系數(shù)以及粘度等因素對(duì)流體噴射過程中液滴體積、拉伸長(zhǎng)度、斷裂時(shí)間以及噴射速度等參數(shù)的關(guān)系。
