How to Choose SMT Solder Paste for Benchtop Pick and Place Machines
Many small-batch assemblers and PCB prototyping users overlook one critical factor: solder paste matching. Even with a high-precision benchtop pick and place machine, wrong solder paste will cause bridging, tombstoning, poor wetting, and low assembly yield. Unlike large industrial SMT lines, desktop SMT systems serve prototyping, small runs, and mixed-component jobs. Their solder paste requirements […]
SMT Feeder Troubleshooting: Common Issues & Quick Fixes for Pick and Place Machines
If you run a small electronics assembly shop, your benchtop SMT pick and place machine works nearly every day. Most downtime we see does not come from the main machine head or motion system. In fact, feeder-related problems account for the majority of daily interruptions. Many small workshop owners run into unexpected stops on their [...]

External Vacuum Packaging Machine: Ideal for SMT Component Protection
For SMT manufacturers, preserving the quality of moisture-sensitive components like BGA, 0402, and 0201 chips is critical to production yield. An external vacuum packaging machine from QiHe offers a reliable solution to protect these components from moisture, oxidation, and contamination during storage and shipping. Key Features of External Vacuum Packaging for SMT H2: Why SMT […]
How to Optimize Assembly Line Layout for Faster LED Light Component Production
In LED light component manufacturing, a poorly designed assembly line layout is one of the most common efficiency bottlenecks. Even with high-quality placement, printing, and soldering equipment, simple adjustments to workstation arrangement, material storage, and space planning can significantly shorten production cycles, reduce downtime, and boost output for LED bulbs, panel lights, and strip lights. […]
Why SMT Solder Joints Have Pinholes & Bubbles? Solder Paste & Printing Fixes
Pinholes and bubbles on SMT solder joints are common welding defects in PCB production, which directly reduce solder joint reliability, cause hidden issues like cold solder and poor conductivity, and even lead to product failure. The root causes mostly lie in two core links: solder paste selection/control and stencil printing process, rather than a single […]
What is the role of air compressors in the SMT industry?
Air compressors convert electrical or mechanical energy into compressed air, providing a high-pressure, dry, and clean air supply, and serve as the “pneumatic power source” for industrial applications. Role in the SMT Industry 1.Air supply for pneumatic components (cylinders, solenoid valves) in equipment such as placement machines, printers, and reflow ovens 2.Air blowing for PCB […]
Why Do SMT Nozzles Get Damaged Frequently? 6 Overlooked Selection & Maintenance Tips
Frequent damage to SMT pick-and-place nozzles in PCB SMT production not only increases consumable costs but also slows down production due to unplanned downtime for replacements. In most cases, the damage is not caused by poor quality, but by overlooked details in nozzle selection, operation and maintenance. Master the following 6 key tips to reduce […]

Reflow Soldering Temperature Curve Setting Guide: Make Your Product Soldering More Reliable
For overseas electronics manufacturers and SMT factory buyers, reflow soldering is the core process deciding product quality and yield, and a proper temperature curve is key to stable, reliable solder joints and fewer batch defects. Wrong temperature settings lead to PCB warpage, component damage, cold/poor solder joints, higher rework costs, delayed deliveries and damaged brand […]
