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 [...]

Confused about picking a benchtop SMT pick and place machine? We break down key specs, common pitfalls and real factory experience for small-batch PCB assembly. Benchtop SMT pick and place machines have become the go-to choice for small electronics workshops, prototype labs and low-volume PCB assembly. Many of our customers come to us after buying […]
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 […]
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 […]
