[Manufacturing Example] Wearable Medical Devices
Achieved and maintained a yield of 99.3%! Introducing a case where mass production started on schedule.
This is a case where we received a request from a major medical device manufacturer for the development and manufacturing of a wearable device for patient monitoring. This product required advanced "functionality" by incorporating multiple sensors, an LCD, and a PCB into a compact housing, in addition to "flexibility" and "biocompatibility" that allows patients to wear it comfortably for extended periods. For the housing material, we selected LSR (Liquid Silicone Rubber), which has excellent biocompatibility and flexibility. We adopted IME technology to place electronic components within the mold and perform integrated molding with LSR, achieving high waterproof and dustproof performance. 【Case Overview】 ■ Annual Production Quantity: 10,000 units ■ Quality Target (Yield): 99.3% ■ Mold Production Period: 3 months ■ Mass Production Startup: 5 months *For more details, please download the PDF or feel free to contact us.
