Microfluidic Chip Aligning Platform

For a microfluidic chip, the upper / lower chip is usually composed of two chips, and the upper / lower chip is usually prepared separately. Therefore, in order to obtain a microfluidic chip with a usage level, upper / lower two chips must be sealed Closing and sealing are the key steps for the microfluidic chip to obtain the actual use function. Only after sealing can the fluid flow in the microchannel formed by the upper / lower chip. The upper / lower chip must be aligned during the sealing process, otherwise it will cause the dislocation of the micro-structure and the micro-channel on the chip, which eventually leads to the inefficiency of the whole microfluidic chip. However, since the surfaces of the upper and lower chips are usually composed of micrometer-scale microstructures and microchannels, the alignment sites are also at the micron level. Due to their small size, it is difficult to perform visual or manual alignment, especially when precise positioning is required. It is challenging to locate the exact alignment points, and XY-axis offsets can easily occur. Moreover, manual adjustment is not only difficult but also very time-consuming.

The Alignment Platform (WH-AM-01) was and designed to align and seal the upper / lower two chips of a microfluidic chip.

In view of the above problems, the alignment platform (WH-AM-01) is equipped with a dual microscope lens, which reduces alignment errors due to local alignment. At the same time, X-Y-θ three-axis moving platform was introduced to further reduce the overall alignment error of the chip and control the alignment error within 10μm.

The product is suitable for the alignment and sealing of the following types of microfluidic chips: PDMS / PDMS, PDMS / glass, PDMS / PMMA, PMMA / PMMA chips for fields such as organ-on- Microfluidic chip alignment and sealing needs. Of course, it fits other areas that require precise alignment.
