When a pick-and-place machine starts producing defects—missing components, skewed placements, or tombstoning—the first instinct is often to blame the feeder, the vision system, or the PCB itself. However, in many cases, the true culprit is smaller and easier to fix: the nozzle. Nozzles are the “fingertips” of the placement machine, directly contacting every component. They are exposed to solder paste residue, dust, and mechanical wear, yet they are often the least maintained component on an SMT line. This article explains why nozzle maintenance is critical, how to identify common problems, and provides step-by-step procedures for cleaning, inspecting, and replacing nozzles. A few minutes of daily nozzle care can reduce placement defects by 50% or more.

n the world of surface-mount technology (SMT), the gap between domestic and imported pick-and-place machines has narrowed dramatically over the past decade. At the forefront of this transformation is Shenzhen ETON Automation Equipment Co.,LTD., a company that has achieved what many thought impossible: developing domestically produced placement machines that rival or exceed imported alternatives in speed, precision, and reliability. But what exactly is inside a ETON machine that enables this performance? This article takes a deep technical dive into ETON's core technologies – from linear magnetic levitation drives to intelligent vision systems, from independent R-axis control to the patented "group pick and group place" architecture. We’ll explain how these innovations improve production efficiency and how ETON has achieved over 95% self-sufficiency in critical components. Whether you are a process engineer evaluating equipment or a technical decision-maker, this inside look will help y

This article provides a systematic, practical guide to diagnosing and resolving the most common pick-and-place-related defects. Based on real-world case studies from contract manufacturers and high-volume lines, we will walk through each defect type, its probable causes, and step-by-step corrective actions. By the end, you will have a troubleshooting framework that reduces downtime and improves first-pass yield.
