Recruiting 02 electronic repair staff to work in Hanoi

Few people realize that the concept of the "Hipot Test"—or electrical safety testing—has long existed within the electrical equipment manufacturing industry. Driven by the growing need to verify the voltage withstand capabilities of conductors, motors, and electrical devices, the industry required a robust and virtually fail-safe method to detect insulation weaknesses before products reached the market.

EMIN and Keysight sincerely thank you for taking the time to attend the 2026 International Electronics & Smart Manufacturing Exhibition in Dong Anh

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.

Many projects encounter a situation where a freshly applied coating looks perfectly uniform and paint consumption matches the estimate, yet additional coating is required during inspection because the thickness is insufficient. This leads many to suspect measurement errors or equipment inaccuracy, whereas the actual cause is a confusion between WFT (Wet Film Thickness) and DFT (Dry Film Thickness)
