Core Fastening and Connection Solutions
Application of PCB
Tin-plated brass nuts and spacers are used for soldering onto PCBs to create threaded connections or for board standoff applications, supporting tape-and-reel packaging. Super Screws are designed for multi-layer PCB assembly and for joining PCBs to sheet metal components.
Clinching（Nylon anti-loosening）
Self-clinching Nut is used for sheet metal fastening in consumer electronics; integrated nylon components provide anti-loosening and anti-detachment functions. Installed using clinching equipment for stable and reliable performance.
嵌件
Used for reinforcing threaded holes in consumer electronics plastic parts to allow for repeated screw disassembly/assembly; materials include brass, stainless steel, and titanium alloy.
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 initial R&D decision window is extremely narrow yet locks in the majority of costs, whereas late-stage corrections incur prohibitive expenses; this severe misalignment of risk and reward necessitates precise judgment at the earliest possible phase.。
15-85 Law
Enterprises tend to focus excessively on visible procurement costs while overlooking the hidden costs that account for 85% of the total; this lack of coordination across design, supply chain, and after-sales service ultimately drives up the Total Cost of Ownership (TCO) throughout the product lifecycle.
