GKG GT++ High-Speed Fully Automatic SMT Stencil Printer

GKG GT++ High-Speed Fully Automatic SMT Stencil Printer

GKG is a leading manufacturer of SMT equipment in China, and GT++ is the flagship or high-performance model in its advanced fully automatic vision printing machine series. It is mainly used in the most front-end stage of PCB assembly production lines for electronic products (such as mobile phones, computer motherboards,

The GKG GT++ is a high-performance automatic solder paste printer developed for precision SMT production where print quality and cycle time must be controlled together. It combines high-speed vision alignment, stable PCB support, programmable print pressure, controlled stencil separation and automatic underside cleaning in one inline platform.

With a published print accuracy of ±18 μm at 6σ and a core cycle time below 7.5 seconds, the GT++ is aimed at factories producing fine-pitch and high-density assemblies at a sustained line speed. Its supported PCB range reaches approximately 510 × 510 mm, allowing the printer to handle standard boards as well as larger production panels.

High-Speed Vision Alignment

The vision system locates PCB and stencil reference marks before printing. Positional correction is applied in the X, Y and rotational directions, helping maintain registration as boards enter the machine.

Precision Printing for Fine-Pitch Assemblies

The published print accuracy is approximately ±18 μm at 6σ, with Cpk stated at 2.0 or higher under the specified test method. Repeat positioning performance is commonly listed at approximately ±12.5 μm at 6σ.

Core Cycle Below 7.5 Seconds

The listed core cycle time is below 7.5 seconds, excluding process conditions that vary by program. Actual throughput must include PCB transfer, alignment, the print stroke, separation and any scheduled stencil cleaning.

Programmable Print Head

Print speed, squeegee pressure and stroke can be stored with the product program. This allows different settings to be created for boards with fine passive components, large thermal pads or mixed aperture designs.

Controlled Stencil Separation

Stencil separation can be adjusted to suit the paste and aperture design. Fine apertures often benefit from a different release profile than large pads, particularly when stencil thickness and aperture geometry create a more demanding area ratio.

Automatic Stencil Cleaning

Dry, wet and vacuum cleaning modes can be programmed individually or in combination. Cleaning intervals can be assigned to the product program instead of being left to operator memory.

Stable PCB Support and Clamping

The support and clamping system holds the PCB during vision alignment and printing. Correct support is especially important for thin boards, large panels, routed areas and double-sided assemblies.

Compact Back-to-Back Line Arrangement

Published GT++ configurations can be installed in a back-to-back printing arrangement with a combined width of approximately 2,830 mm. This may benefit dual-line factories where floor-space efficiency is important.

The GKG GT++ can be considered for:

  • Smartphones and smart electronic devices
  • Communication and networking products
  • Automotive electronic modules
  • Medical electronics
  • Industrial control systems
  • Server and computing boards
  • Power electronics
  • High-density consumer electronics
  • Semiconductor-related PCB assemblies
  • Fine-pitch and miniature-component production
  • High-volume contract PCBA manufacturing
  • Mixed boards combining small apertures and large thermal pads

The machine is most useful where its accuracy and cycle-time capability are supported by suitable stencil design, controlled solder paste handling and an effective SPI process.

The GT++ should be positioned as the high-speed, high-precision option within these product pages.
