Top 1 Turnkey SMT Line Solutions Expert in China

A turnkey SMT line is a complete, ready-to-run assembly line delivered by the provider. It includes all necessary machinery (solder paste printer, pick-and-place, reflow oven, AOI/SPI, conveyors, etc.) plus peripheral equipment and infrastructure. The provider handles everything – from layout and equipment selection to installation and testing – so the line is “plug-and-play”.

Our “0-to-1” service means taking you from project conception (no production line) to full operation. We start with consulting and layout design, select all machines, set up and optimize the line, train your operators, and provide documentation. In short, we manage every stage of the build, delivering a fully integrated factory line.

For example, industry leaders include Panasonic, Hanwha (Samsung), FUJI, Yamaha, and JUKI , and we can supply these (both new and refurbished). In addition, we manufacture our own Meraif – brand machines (reflow ovens, wave soldering, printers, AOI/SPI, soldering robots, etc.) for customers who require customized or cost-effective alternatives.

Beyond selling machines, we offer full consulting and integration services. This includes production line engineering (layout, MES/software integration), operator training (programming and process), and ongoing maintenance. We also supply all spare parts/consumables (feeders, nozzles, solder paste, stencils, etc.) so you can maintain the line. Our goal is a “one-stop solution” – we handle everything from system integration to after-sales support.

A mixed (or “mixed technology”) SMT line is designed for high flexibility. It typically uses modular equipment (such as dual-lane or multi-head pick-and-place machines) and interchangeable processes to handle a variety of products on one line. This is common for high-mix, low-volume manufacturing (small runs of many different boards) . Such a line allows quick changeovers and can even assemble two different products simultaneously, maximizing utilization.

Yes. Meraif customizes lines for any volume. For small-batch or prototype production, we build high-mix, low-volume lines that allow rapid changeovers and accommodate custom components. For mass production, we design low mix, high-volume lines (like those used for smartphones or LED panels) with fast machines and inline inspection. In both cases, the line is sized and automated for your expected order quantities.

SMT assembly lines serve virtually all electronics industries. Low-mix, high-volume lines are common in consumer electronics, automotive modules, telecom equipment, lighting (LEDs), and appliances. High-mix, low-volume lines are used in aerospace, medical devices, military/defense electronics, prototyping labs, and specialized industrial applications. Meraif’s solutions are applied wherever PCBs are assembled – from toys to turbines.

We provide complete after-sales support. This includes on-site commissioning and training, prompt troubleshooting assistance, and a full supply of spare parts. We emphasize “worry-free” maintenance – proactively checking your line, preventing faults, and updating your staff on new technologies. Our 24/7 technical hotline and field service team ensure that help is always available when you need it.
