Not all solder paste works well for small desktop SMT machines. Learn alloy types, particle size, viscosity and storage tips to get stable soldering results for your small-batch PCB assembly. For hobbyists, small electronics workshops and prototype labs, desktop SMT pick and place machines are the go-to solution for low-volume PCB assembly. But many users […]

Component Selection

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 […]


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 […]

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. […]

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 […]

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 […]

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 […]
