TRA SX320S | Semi-Automatic Solder Paste Printing Machine

SX-320S Solder Paste Printer

TRA Semi-Automatic Stencil Printer

The TRA SX320S is a semi-automatic solder paste printer for the stencil-printing stage of SMT PCB assembly. Its 320 × 500 mm worktable accommodates a maximum printing area of 250 × 420 mm, providing a dedicated workstation for applying solder paste before component placement.

PLC control and a 4.3-inch SamDraw colour touchscreen provide a convenient operating interface. Linear slide guidance supports smooth printing movement, while the dual-squeegee assembly and adjustable printing stroke give operators practical control over the printing setup.

The micro-adjustable printing table supports setup for single- and double-sided PCBs. Adjustable stencil-clamping arms, an up/down adjustment handwheel and LED working lights provide access and visibility during preparation. Two start buttons, located on opposite sides of the control panel, must be operated simultaneously to initiate the machine cycle.

Key Features for TRA SX-320S

The PLC-based control system is operated through a 4.3-inch SamDraw colour touchscreen, providing a central interface for routine machine operation.

Adjustable guide rails allow the stencil frame to be clamped and positioned for the printing setup. The catalogue specification table lists a maximum frame size of 550 × 900 mm.

The linear slide guides the printing mechanism through its travel, supporting smooth movement and consistent printing operation.

The printing head incorporates two squeegees. This is a dual-squeegee arrangement, not a claim of simultaneous printing on both sides of a PCB.

The table provides fine adjustment for board positioning and setup. The catalogue identifies it as suitable for printing single- and double-sided boards.

The left and right start buttons must be activated together. This operating arrangement supports deliberate two-handed cycle initiation; no specific safety certification is claimed.

The proximity-switch arrangement allows the printing stroke to be adjusted for the job. Its sliding adjustment provides access to the stroke-setting positions.

An up/down adjustment handwheel assists mechanical setup, while LED working lights illuminate the printing area.

Production Advantages TRA solder paste printer

• Accessible operation: Touchscreen control brings routine operation to a central interface
• Practical setup adjustment: Adjustable arms, the handwheel and micro-adjustable table support preparation for different board and stencil jobs.
• Consistent guided motion: Linear slide guidance and the stated repeat precision support repeatable operation.
• Job-specific stroke setting: Adjustable proximity switches allow printing travel to be set for the task.
• Visible work area: LED lighting assists operators during setup and inspection of the working area.
• Controlled cycle initiation: The simultaneous dual-button arrangement requires intentional operation from both sides of the panel.
