1. Fatal Fault on Site A certain automotive welding workshop, Siemens S7-300 PLC (6ES7 315-2EH14-0AB0) suddenly reported error 0x1A3B, with 32 DP slaves going offline collectively. The monitoring screen displayed:<span>[2023-05-12 03:15] PROFIBUS-DP System Fault: Telegram timeout (Slave 17-32)</span> The signal amplitude was only 0.8Vpp (standard requirement ≥1.5Vpp), with a rise time jitter of 35ns (IEC61158 … Read more
The 3D silicon capacitor is a capacitive component manufactured based on semiconductor processes. Its development requires overcoming key technologies such as deep silicon etching, heterogeneous integration of dielectric materials and silicon-based materials, and balancing interface stress caused by differences in thermal expansion coefficients. Geli Micro has successfully developed the compact, high-density, low-parasitic, and highly reliable … Read more
Special Surface Treatments for Touch Screen Glass Covers The current mainstream processes for cover glass surface treatments include AG (Anti-Glare), AR (Anti-Reflection), AF (Anti-Fingerprint), AM (Anti-Microbial), and AUV (Anti-UV). In this issue, we will delve into the key technologies of the four major surface treatment processes for cover glass: AG (Anti-Glare), AR (Anti-Reflection), AF (Anti-Fingerprint), … Read more
Comparing LCD screens and OLED screens is akin to comparing fuel vehicles with electric vehicles. The acceleration and power levels are simply not on the same scale. The emergence of new technologies inevitably leads to the obsolescence of older ones, often without any warning. Nokia phones are a prime example of this. First, let’s understand … Read more
