Abstract

Microfluidics devices have been applied in the biomedical field to manipulate the tissue fluids in channels with dimensions between 5-500 lm. Microfluidics device manufactured by a microfabrication process consisting of design, microstucturing and back-end processes. One application of microfluidics is a passive mixing microchannel. In this device, the liquid will flow through the channel without any moving parts and the pressure from the outside to produce a fluid mixing. It is important to design the shape of the channel to generate a nice passive mixing microchannel. Low power CO2 laser is used to process microstucturing as cutting tools to produce microfluidic devices on acyilic material. Surface roughness lines were designed to be observed. In this study, the design process channel carried by the experimental method through the parameters that affect the output of the process is the power of laser cutting, cutting speed and design channel. And then the fabrication of microfluidics with back-end processing is done by the process of merging with a thermal bonding method. Finally, From the experimental results, the design of the channel 1 has an influence on all the parameters for surface roughness compared with a channel design 2.

Abstract

Pada tulisan ini akan dibahas metode modifikasi dari Photolitography yaitu Visible Ligth Maskless Photolitography, perbedaannya menggunakan sinar tampak (visible light) dan tanpa mask (cetakan) selanjutnya diaplikasikan pada fabrikasi jalur listrik PCB (printed circuit board). [DI1]Kelebihan metode adalah mudah, murah tetapi mampu membuat profil rumit dan aman. Cara kerjanya model/ profil dibuat di komputer/ laptop kemudian dipancarkan melalui DLP projector. Pada bagian bawah projector dipasang PCB yang sudah dilapisi Negative Photoresist sehingga terjadi proses exposure. Selanjutnya dilakukan proses developing dan eching sehingga terbentuk profil sesuai desain. Pada jenis projector Infocus IN114A ditemukan parameter terbaik: posisi lensa pemfokus pembesaran 3X berjarak 3 cm dibawah DLP projektor dan 14 cm diatas material uji PCB, menggunakan kombinasi warna hitam (R:0 G:0 B:0) dan biru terang (R=0, G=176, B=240) dengan waktu prebake 2 menit, spin 2.000 rpm, exposure 3 menit, developing 5 menit, Postbake 5 menit dan Eching 5 menit. Profil jalur listrik yang berhasil dibuat diantaranya: garis, huruf, alur listrik, dan bentuk microcontroller. Hasil pengukuran Scanning Electron Microscope (SEM) profil garis terkecil yang dapat dibuat yaitu m132 m dan memiliki kekasaran tepi (deviasi) 6,6 m.
