Explore our top-tier industrial connectors engineered for extreme environments, heavy vibrations, and moisture resistance, perfectly suited for the demanding applications in Hanoi's evolving tech landscape.
Hanoi, the vibrant capital of Vietnam, has rapidly transformed into a premier hub for high-tech manufacturing, automotive assembly, and telecommunications infrastructure in Southeast Asia. As global supply chains diversify, Northern Vietnam has seen a massive influx of Foreign Direct Investment (FDI) from multinational electronics and electric vehicle (EV) giants. This rapid industrialization demands components that guarantee absolute reliability. Among these critical components, Waterproof Solder Connectors have become indispensable.
The unique climate of Hanoiācharacterized by high humidity, heavy monsoon rains, and fluctuating temperaturesāposes a significant challenge to electronic and electrical systems. Standard interconnects are prone to corrosion, short circuits, and signal degradation under such harsh environmental conditions. Waterproof solder connectors, featuring IP67 and IP68 ratings, provide an impenetrable seal against moisture, dust, and chemical ingress. Furthermore, the soldered termination ensures a mechanically robust and electrically stable connection that outperforms traditional crimping in high-vibration scenarios, such as moving vehicles or heavy industrial machinery.
From the sprawling industrial parks in Bac Ninh and Thai Nguyen on the outskirts of Hanoi to the advanced smart city projects within the capital, the integration of IoT devices, 5G base stations, and smart grid infrastructure relies heavily on these robust connectors. As a leading manufacturer and supplier, we are committed to providing Hanoi's industries with customized, high-performance waterproof soldering solutions that ensure uninterrupted power and data transmission.
As an industry leader supplying the global and Vietnamese markets, Shandong Longli Electronics Co., Ltd. is recognized as a national-level "Key Little Giant" enterprise (specialized, refined, unique, and innovative). We are proud to be a provincial-level Gazelle Enterprise, a Hidden Champion, and a Manufacturing Single Champion in Shandong Province.
To support the complex technical requirements of modern industries, the company operates state-of-the-art R&D centers in Linyi, Xi'an, and Jinan. We possess comprehensive third-party service capabilities, including rigorous testing and inspection services, backed by prestigious certifications such as CMA and CNAS. Our commitment to quality ensures that every waterproof solder connector exported to Hanoi meets the highest international standards.
We are dedicated to forging powerful linksāboth technologically and commercially. Our mission is to provide secure, waterproof, and durable connections that drive the future of global industries, particularly supporting the rapid modernization of Vietnam.
The company primarily offers seven major categories of products, including military connectors, smart grid connectors, new energy vehicle connectors, railway locomotive connectors, mining connectors, petroleum connectors, and marine connectors, encompassing over 130 series and thousands of specifications.
These products are widely used in aviation, aerospace, military electronic equipment, as well as various sectors of the national economy such as power grids, new energy, railways, telecommunications, petroleum, and coal mining. In Hanoi's rapidly expanding infrastructure, our connectors are the invisible heroes ensuring system integrity.
Our waterproof solder connectors are designed to thrive in the specific operational environments found in Hanoi and the broader Vietnamese market. Let's explore how our technology is being applied locally:
Vietnam is experiencing a massive shift towards green mobility. Hanoi's streets are increasingly populated with electric scooters and electric cars. The battery management systems (BMS), motor controllers, and charging interfaces of these vehicles require highly reliable, waterproof interconnects. Our solder connectors provide the necessary current-carrying capacity and IP68 waterproofing to withstand flooded streets during the rainy season, ensuring rider safety and vehicle longevity.
As Vietnam rolls out its 5G networks, telecom base stations are being rapidly deployed across Hanoi's urban and suburban landscapes. These outdoor installations face continuous exposure to UV rays, heavy rain, and high humidity. Our gas-sealed and waterproof circular connectors ensure that RF signals and power are transmitted without interference or degradation, reducing maintenance costs for local telecom operators.
Surrounding Hanoi, the agricultural sector is adopting IoT technology for smart farming. Sensors monitoring soil moisture, weather conditions, and automated irrigation systems require rugged connectors. The soldered joints provide excellent tensile strength, while the waterproof housings protect sensitive electronics from mud, water, and agricultural chemicals.
With the development of Hanoi's Metro network, railway-specific circular connectors are in high demand. These connectors must withstand constant vibration, electromagnetic interference, and environmental exposure. Our LXC Series and similar products are rigorously tested to meet the strict safety and performance standards of modern railway transit.
The company has undertaken more than 60 research projects, including the Torch Program of the Ministry of Science and Technology, provincial major science and technology projects, and provincial key R&D programs. It has received 25 scientific and technological awards, including provincial science and technology awards and provincial SME technological progress awards.

Why do engineers in Hanoi prefer solder connectors over other termination methods? The answer lies in the atomic-level bond created during the soldering process. Unlike crimped connections, which rely on mechanical pressure and can loosen over time due to thermal cycling or vibration, a properly soldered joint forms a solid, metallurgical bond between the wire and the connector contact.
This results in exceptionally low contact resistance, which is crucial for high-current applications such as EV charging and industrial power distribution. Furthermore, when combined with our advanced waterproof sealing technologiesāutilizing high-grade silicone O-rings, potting compounds, and threaded coupling mechanismsāthese connectors completely isolate the conductive elements from the external environment.
Our manufacturing processes utilize precision CNC machining for the connector shells, ensuring tight tolerances that guarantee IP68 performance. The contact pins are typically gold-plated over nickel, providing excellent conductivity and resistance to oxidation, even in the humid, sulfur-rich air sometimes found in heavy industrial zones.
