A device may operate stably for months, yet suffer cracks, broken solder joints, or snapped component leads after being transported. What surprises many engineers is that the vibration amplitude during transport is no greater than usual. The root cause lies in a specific frequency range where the product's structure absorbs energy most intensely, triggering resonance and causing continuous stress concentration at a single point.

Một kiện hàng gần như không bao giờ bị rơi ngay khi vừa rời khỏi nhà máy. Quãng đường hàng trăm kilomet trên xe tải, container hay băng chuyền mới là giai đoạn diễn ra đầu tiên, nơi bao bì liên tục chịu rung lắc trong nhiều giờ. Chỉ sau đó mới đến những cú va chạm khi bốc xếp, giao nhận hoặc rơi ngoài ý muốn.

An automatic servo wire stripping machine delivers high precision, stable performance, and seamless integration into modern production lines. But when is the right time for manufacturers to invest in one? This article explores the key situations where upgrading can improve productivity and wire processing quality.

Learn how to choose the right wire stripping machine based on wire size, production volume, and manufacturing requirements. Make smarter equipment investments while optimizing long-term operating costs.

An automatic wire stripping machine improves productivity, reduces errors, lowers labor costs, and ensures consistent cable processing quality in industrial manufacturing.

Bridging the gap between theoretical simulation and actual hardware implementation remains the greatest challenge in advanced engineering projects. In fields such as radar, 5G/6G, and quantum computing, a lack of synchronization between the design environment and operational hardware often prolongs development timelines

For many factories, downtime is often viewed as an unexpected event that strikes during a production shift. In reality, however, the situation is different. Before a motor fails, a variable frequency drive (VFD) reports an error, or a production line requires an emergency stop, the equipment typically emits multiple warning signals—such as abnormal temperature rises, excessive vibration, degraded power quality, or unstable communication performance. These indicators can persist for days or even months before an actual breakdown occurs

The widespread adoption of wideband semiconductor components such as SiC and GaN in photovoltaic inverters, motor drives, and automotive charging systems has driven the switching frequency and power density of three-phase inverters to unprecedented levels. However, this development has also brought with it severe measurement challenges: high voltages, intense electromagnetic interference, and the requirement for ultra-fast switching signal capture at the nanosecond scale

Is it dangerous to live near a BTS base station? Find out the assessments from the WHO, ICNIRP, Vietnamese regulations, and the actual electromagnetic radiation levels in residential areas.

Set up two multimeters at the same location and their displays may still differ by several volts or a few percentage points. The difference often comes from how each device processes the input signal before converting it into a displayed value.
