Product details

Surface Mount Technology (SMT), as the mainstream process for modern electronic assembly, directly mounts components onto the PCB surface, replacing traditional through-hole (THT) mounting, thus achieving "miniaturization, integration, and high reliability" of electronic devices. Its assembly capabilities are deeply synergistic with PCB processing, playing a crucial role in consumer electronics, automotive electronics, and industrial control. Compared to traditional assembly processes, SMT assembly possesses four core advantages and distinct characteristics, precisely meeting the development needs of the electronics manufacturing industry.

High-speed placement capability: Utilizing high-speed pick-and-place machines (placement speed ≥ 50,000 points/hour), fully automatic solder paste printers (printing accuracy ±0.01mm), and reflow ovens (precise temperature control in 8-12 temperature zones), a fully automated production line is constructed. A single line can assemble 3,000-5,000 PCBs per day (based on smartphone motherboards), which is 50-100 times more efficient than manual assembly. For example, when assembling PCBs for laptop energy storage boards, the entire process of "solder paste printing → component placement → reflow soldering → inspection" can be automated, with a single board assembly time ≤ 3 minutes, matching the mass production rhythm of PCB processing. Continuous uninterrupted production: The production line supports 24-hour continuous operation. The MES system monitors equipment status and production progress in real time, automatically issuing early warnings for faults (such as pick-and-place machine nozzle blockage, abnormal reflow soldering temperature), reducing downtime maintenance time to ≤ 1 hour/day, and increasing the overall equipment efficiency (OEE) to ≥ 85%, ensuring on-time delivery of mass production orders.

Reduced labor costs: Automated production lines require only 2-3 people for monitoring and operation, replacing a traditional manual assembly team of 10-20 people. This increases per capita output by 10-15 times and reduces labor costs by 60%-80%. Improved material utilization: Solder paste printing uses stencils for precise dosage control (solder paste usage error per PCB ≤5%), achieving a component placement yield of ≥99.9% and reducing material waste. Simultaneously, large-scale procurement of placement consumables (such as solder paste and nozzles) can reduce material costs by 15%-20%, making the unit assembly cost of mass-produced products 40%-50% lower than small-batch manual assembly.
