Laser-cut HOME button The devil is in the details
When it comes to the Home button, most people are likely familiar with it. Since Apple released the first-generation iPhone in 2007, this button has become widely recognized. Today, the Home button has evolved into one of the essential buttons on every smartphone and remains the most frequently used key.
The HOME button handles numerous functions—from activating Siri and switching apps to simply returning to the home screen. As smartphones have evolved, the HOME button has grown increasingly vital to overall device design. A well-executed HOME button design significantly enhances a phone's aesthetics. Furthermore, with the integration of fingerprint recognition, the HOME button has also become the phone's fingerprint scanner.
Over the years, the design of the smartphone HOME button has evolved beyond the classic circle to include oval, rectangular, and other shapes.
Despite these variations in appearance, the internal structure of mainstream HOME buttons remains similar. It consists of laser-cut sapphire crystal, a stainless steel detection ring, a capacitive single-point touch sensor, and a tactile switch. The sapphire crystal precisely focuses the finger's touch and protects the sensor.
After Apple pioneered sapphire material in the iPhone 5s's home button, this superior material gained widespread attention from consumers and smartphone manufacturers. As the world's second-hardest material after diamond, sapphire is now used in camera covers, buttons, and displays on some smartphones, offering enhanced protection.
However, due to sapphire glass's extreme hardness, machining it into a high-quality Home button with smooth, curved edges is no easy feat. Even during edge cutting, chipping and cracking can render the entire screen unusable, demanding higher precision in manufacturing processes.
Addressing sapphire cutting demands in the 3C manufacturing industry, Tor Laser's ultra-fast laser precision cutting machine is primarily used for cutting smartphone sapphire home buttons, camera protective lenses, fingerprint recognition glass, and other brittle materials. Equipped with an ultra-fast laser, it delivers high processing accuracy, minimal heat-affected zones, burr-free and residue-free edges, and excellent long-term stability.
A small home button may seem insignificant, yet as a frequently used component in smartphones, it directly impacts the user's daily experience. Even in such minute details, Tor Laser relentlessly pursues excellence, providing the market with higher-quality processing technology.
