HW-QS4340 Printer
The HW-QS4340 is a fully automatic high-precision screen printer from a China SMT machine manufacturer, engineered to deposit solder paste uniformly and accurately onto PCB pads ahead of chip mounting. Controlled through a Windows XP interface with a high-performance CCD and image processing system, it achieves repeat printing accuracy of ±0.02 mm and printing accuracy of ±0.025 mm. With a print cycle under 8 seconds per board, stencil sizes up to 737x737 mm and PCB capacity up to 600x400 mm, it anchors the front end of demanding SMT production lines. The SMEMA interface lets it hand boards to loaders, conveyors and chip mounters automatically, keeping the whole line balanced and moving without operator intervention.

SMT Industry News
October 2026's NEPCON Asia highlighted next-generation SMT placement systems and advanced packaging, including the China debut of the ASMPT SIPLACE V platform, Essemtec's all-in-one SMT and packaging solutions, and Hanwha Semitec chip mounters paired with AMR robots. The common thread is that automation and process data now decide line competitiveness, and printing is where that quality chain begins. AI server boards and high-end computing PCBs are also pushing factories toward tighter, more repeatable solder paste printing, exactly the role a fully automatic printer such as the HW-QS4340 plays at the head of a high-precision SMT production line. For buyers evaluating automatic printers, the HW-QS4340 also stands out on total cost: lifetime free software maintenance and timely upgrades protect the investment well beyond the initial purchase.
Applications
The HW-QS4340 is built for volume PCB assembly in consumer electronics, communications, automotive electronics, LED lighting and industrial control. Its CCD alignment, SMEMA interface and single-stage conveyor let it join a fully automatic SMT production line between a loader and a chip mounter, delivering uniform paste deposition that maximizes placement yield. As a high-precision automatic screen printer from a China SMT machine manufacturer, it gives factories a reliable, upgradeable printing platform with lifetime software support and a single-stage conveyor that is simple to maintain on busy shop floors.
