ULTRASONIC WELDING-BASED MICROFLUIDIC DEVICE AND METHOD OF MANUFACTURING THE SAME
First Claim
1. An ultrasonic welding-based microfluidic device comprising:
- a bottom board having two welding stoppers formed right and left with a certain height and a certain interval;
a top board having two energy directors formed having an interval greater than interval between the welding stoppers, located at each of two welding stoppers, and welded to the bottom board while ultrasonic welding; and
a channel formed between the two welding stoppers as the bottom board is bonded to the top board by the ultrasonic welding.

Abstract
A method of manufacturing an ultrasonic welding-based microfluidic device, the method including: forming a bottom board having two welding stoppers formed right and left and having a certain height and a certain interval; forming a top board having two energy directors formed with an interval greater than the interval between the two welding stoppers; putting the top board on the bottom board to locate the energy directors at the outside of welding stoppers, respectively; and welding the top board to the bottom board by using ultrasonic welding, wherein a channel is formed between the two welding stoppers without additional energy directors. Accordingly, it is possible to prevent a phenomenon that a fluid irregularly flows due to an uneven surface formed on a side of the channel while the energy directors are melted.
