The Samsung Galaxy Z Fold3, which was recently launched, is the world's first folding screen smartphone to receive an IPX8 certificate. How the South Korean tech giant made the device waterproof considering the design has its own complexities.
Samsung claims to make the Galaxy Z Fold3 is not easy. Unlike smartphones in general, the Galaxy Z Fold3 is made in three parts, namely two bodies and one hinge.
To protect the body, Samsung applies the same method with smartphones on the market. But on the hinges, they have to turn their brains again because every time they open the gaps can become water entrances that can cause component damage.
The engineers use a special material that is added with lubricating oil to protect the hinges from rust and corrosion. Meanwhile, to protect the mainboard from electrical short circuit due to water, Samsung added rubber and CIPG (Cured In Place Gasket).
These two materials cover the gap between the connecting ends of the flexible printed circuit board. So as to protect important parts that are vulnerable to water exposure.
As a result, users are free to worry when using the Galaxy Z Fold3 in the rain. Or even capture exciting moments with your family while in the pool.
