Starting from iPad Pro 2018, Apple introduced a rectangular design with straight edges to the iPad Pro series, coupled with an ultra-thin body made of aluminum and metal, the new shape design has injected new vitality into the iPad Pro.
After the iPad Pro 2018’s release, some users said that their devices were easy to “bend”, and even the body was distorted without being subjected to external forces.
Later Apple said, “One iPad Pro One Body Design ” to explain this fact. They stated that the flatness specifications of the iPad Pro required that the deviation of the entire edge of any side should not exceed 400 microns (about four sheets of thin paper) and the iPad Pro ’s new straight-edge design and antenna splitter may cause the fuselage to bend more clearly in some viewing angles, but these differences will not affect the strength of the fuselage and product features.
Although such a test may not be fair to a device that is only 5.9 mm thick and has an aluminum metal case, after all, any sufficiently thin electronic product has the basic leverage In principle, it is difficult to avoid being bent.
Apple products always in thin and light designs, but this also makes some products more likely to be damaged. The previous iPhone 6 “bent door” incident is an example. Later, Apple adopted a new aluminum alloy material in the iPhone 6S to resolve this. problem.
