SMT & THT Automation Insights

Southern Machinery's S7020 4-head odd form inserter automates rice cooker PCB assembly, feeding, inserting and clinching pin, eyelet and terminal components that manual stations cannot keep up with. Built for the THT bottleneck on home appliance control boards, the machine handles terminals from 0.5 mm to 1.2 mm on PCBs up to 380 x 280 mm standard, with 360-degree insertion angles and inward or outward clinching for mechanical retention before wave soldering. This buyer guide covers what the machine is used for, typical applications in rice cookers, power supplies and LED drivers, how it fits into a complete SMT/THT assembly line, the key selection parameters to evaluate, and the labor and quality ROI case for EMS factories. Published specs, applications and evaluation checklist from Southern Machinery, Shenzhen, China.

Automate ribbon cable stripping and splitting in your PCB assembly line with Southern Machinery's S330A Computer Wire Stripping Machine. Designed for EMS providers and OEMs producing automotive electronics, industrial controls, and consumer appliances, the S330A replaces inconsistent manual wire preparation with computer-controlled precision — delivering repeatable strip lengths, clean insulation removal, and batch-to-batch consistency. Positioned at the pre-insertion stage of the THT workflow, it feeds stripped wire assemblies directly to manual or automated insertion stations and downstream Wave Soldering processes. By eliminating manual stripping variability, manufacturers reduce rework, improve line balancing, and free skilled labor for higher-value assembly tasks. Backed by Southern Machinery's global support network — founded 2011, Shenzhen, 237+ customers worldwide — the S330A is a practical investment for any facility where ribbon cable interconnects drive throughput and quality outcomes.

When irregular connectors, relays, shields, and other non-standard parts disrupt an SMT line, the pickup tool is often the constraint. Southern Machinery helps EMS and manufacturing engineering teams evaluate custom nozzles and grippers around component geometry, pickup surfaces, center of gravity, side clearance, and host-machine interfaces. The result is a more deliberate path from manual handling to stable automated placement, with configuration and final feasibility confirmed against the actual component and production line.
