Extreme miniaturization makes it possible to insert an ultra-sound probe through the esophagus and to position it directly behind the heart resulting in an unobstructed image of the beating heart in very high resolution.
Key elements of this product are thin double layer flex-PCBs with traces one hundredth of a millimeter wide and plated with a thin gold layer in DIG-technology. These microscopic traces can only be manufactured with semi-additive-processing. To implement the SAP-technology substantial investments in equipment and the development of challenging processes were necessary. Since the beginning of this year we are proudly supplying Flex PCBs manufactured in SAP-technology for usage in a cutting-edge medical product on the market.
