Core Fastening and Connection Solutions
Application of PCB（SMT）
Tin-plated copper nuts and spacers are used for PCB soldering to create threaded connections and are available in tape-and-reel packaging. High-current terminals are designed for conductive connections in high-power applications, while 'Super Screws' are utilized for multi-layer PCB assemblies and PCB-to-chassis&sheet metal connections.
Riveting （Clinching、Blind Riveting）
Self-clinching Nut/Fastening solutions for server enclosures include Self-clinching nut or standoffs, blind rivet nuts, and rivets. For grounding, self-clinching terminals are integrated into the sheet metal. Our sealed fasteners provide IP68-rated protection, and flat-head rivets are available for applications requiring superior surface flushness.
UQD Connectors (Liquid Cooling System)
UQD connectors feature non-drip, high-flow, and quick-connect capabilities; they are used in AI server liquid cooling systems to achieve rapid, sealed connections between cold plates and piping, ensuring efficient heat dissipation and convenient maintenance.
Screws(Anti-loosening.Sealing、Captive Screw）
Bolts achieve anti-loosening through the use of SEMS (integrated assemblies) and pre-applied adhesives. To reach an IP68 sealing rating, adhesives can be pre-applied under the head or on the threads, or specialized sealing rings can be integrated. Furthermore, captive screws remain attached to the panel after disassembly, facilitating easy maintenance of equipment panels.
Industry Challenges
Project Cycle Cost Influence Model
The primary R&D challenge in modern industry is that early-phase strategic decisions lock in most expenditures despite a limited time window. Conversely, the cost of rectification in later stages is extremely high, leading to a significant disproportion between risk exposure and potential gains.
15-85 Law
An over-focus on explicit procurement costs leads to the neglect of hidden costs—which account for 85% of the total. This lack of systematic coordination across design, supply chain, and after-sales service significantly inflates the Total Cost of Ownership (TCO) across the entire product lifecycle.
