Medical sensor(blood glucose meter) of Au patterning on PET substrate

The process was developed several years ago for touch panel industry, which now is successfully replaced the wet etching process. And with long time developing and higher requirements from mobile phone industry, this process is completed and used in many other applications, mainly for developing or manufacturing sensor or circuits for OLED, medical, solar cell, consumer electronics, and many R&D cases.

We have done a lot of cases with different materials coated on different substrates, the typical one is ITO patterning, With the different absorption rates of laser, we could remove some material and no hurt to the substrate. The coating thickness usually less than 10um, and most of them is less than 1um.

The strength of this process is that it could etch 20/20um patterns which makes it possible to design the whole pattern very small and tight, and easy CAD input helps the designers have a fast prototyping and demonstration.And recently we have succeed in making a 2um line width pattern for a world-famous company in laboratory. In addtion, with improved technologies, double sides coating and patterning of different design is also possible
