PMMA)作為微流體裝置的基材,以高精密五軸數控加工機(Computer
Numerical Control , CNC)進行微流體裝置的微铣削製程。工件在經過微铣削
加工後加工表面會有刀紋路及毛邊的產生,這對微流體裝置來說有一定的
影響,刀紋路會使表面粗糙度變差、毛邊在微流道內會造成改變液體流向
或氣泡的產生,故本文將會先針對微铣削高分子聚合物進行參數的調查,
了解加工參數對表面粗糙度及毛邊的影響,並將其進行優化以製造低表面
粗糙度及小毛邊大小的高品質之晶片。並且透過了解微铣削加工的加工極
限(加工機所能加工最小的間隔牆厚度與最深的加工深度、具有高長寬比的
微柱…等等方式),並利用五軸切削工具去創造與其他機台無法製作出的更
加微小尺度與複雜的圖形特徵。在 CNC 直接铣削製造微流道凹模最小的特
徵尺寸會受限於現有的刀具尺寸(刀直徑:寬度與刀長:深度),因此可以製造
出塑膠及金屬凸模用於 PDMS(Polydimethylsiloxane)的翻模或使用熱壓印法
去製造出直接铣削所無法加工的微流道圖形(流道尺寸小於刀徑、流道深度
高於刀長等…等),便能進行多樣化的晶片製作。
在後端的是封裝製程,因為目前尚無完美的熱塑性材料接合製程,每
種接合方法都各有其優缺,故依據每個微流道晶片的需求選擇其所適合的
接合方法,逐一呈現目前始能完成的不同裝置。因此在本論文中,除了探
討铣削參數對於毛刺及表面粗糙度的影響之外,再以製造凸模的方式對微
铣削的能力進行探討。最後再以依各流道設計及需求選用其適合的接合方
法。希望能提供一種以精密五軸 CNC 微铣削為前段製程的關鍵進行高精度
且微小複雜的特徵結構的加工並達到製造少量且多樣的微流體裝置。
摘要(英) In this study, Poly Methyl Methacrylate (PMMA) was used as the substrate
for microfluidic devices. and the micro-milling process of the microfluidic device
is carried out by a high-precision five-axis Computer Numerical Control (CNC)
machine. After the micro-milling , the surface will have milling traces and burrs.
which has a certain impact on microfluidic devices. The milling traces can
deteriorate the surface roughness, and the burrs in the microfluidic channel can
cause changes in the flow direction of the liquid or the formation of air bubbles.
Therefore, I investigate the parameters of micro-milled polymers first, and
understand the influence of processing parameters on surface roughness and
burrs. We try to optimized to produce high-quality chips with low surface
roughness and small burr size. By understanding the machining limits of micromilling processing,( The processing machine can process the smallest partition
wall thickness and the deepest processing depth、micropillar features with high
aspect ratios…) Use five-axis CNC to create smaller scales and complex graphic
features that cannot be produced with other equipment. In CNC direct milling to
manufacture microfluidic dies, the smallest feature size is limited by the existing
tool size .( milling cutter’s diameter :width、milling cutter’s length :depth)
Plastic and metal can be manufactured for inverted feature as micro-mold turning
PDMS or hot pressing to create microfluidic patterns that cannot be machined by
direct milling. Then can enables a variety of chip production.
At the back end is the bonding process, as there is no perfect thermoplastic
bonding process currently. Each bonding method has its own advantages and
disadvantages. According to the needs of each microfluidic chip, select its
suitable bonding method, and present the different devices that can be completed
iii
one by one. in this study, in addition to discussing the influence of milling
parameters on burrs and surface roughness, the ability of micro-milling is
discussed by manufacturing inverted feature as micro-mold. Finally, the suitable
bonding method is selected according to the design and needs of each microchannel. We hope to provide a precision five-axis CNC micro-milling as the key
to the front-end process, perform high-precision and micro-complex feature
structure processing, and achieve the manufacture of a small number and variety
of microfluidic devices.
