6.1 Пакеттен чыгаруу жана жайгаштыруу

1. Принтерди таңгагынан этияттык менен чыгарыңыз.
2. Place the printer on a sturdy, level workbench in a well-ventilated area.
3. тууралаңыз Adjustable Foot Of Base (Figure 5.1) to ensure the machine is perfectly level and stable.

6.2 Screen Template Installation

1. Lift the screen frame holder to its upright position (Figure 6.1).
2. Place your SMT stencil (screen template) into the frame holder.
3. Secure the stencil using the four Template Fixed Knobs with pressure plates (Figure 6.2). Ensure the stencil is firmly held without excessive tension.

Figure 6.2: The screen template is secured by four knobs with pressure plates, providing a stable and firm attachment for printing.

6.3 PCB Positioning

1. Place the PCB onto the Жумушчу платформа.
2. колдонуу Positioning Needles, Fixed Plates, жана Movable Ejector Pins (Figure 6.3) to precisely align the PCB. The movable ejector pins and support plate allow for flexible positioning, convenient for single or double-sided printing.
3. Adjust the position of the PCB using the X Axis Rotary Knob жана Y Axis Rotary Knob (Figure 5.1) until it is perfectly aligned with the stencil apertures.

Figure 6.3: The working platform features movable ejector pins and support plates for flexible PCB positioning, along with fixed rods and plates for precise circuit board alignment.

7. Иштөө нускамалары

7.1 Adjusting Printing Height

1. Lower the screen frame until it rests just above the PCB.
2. колдонуу Бийиктикти жөндөө баскычы (Figure 5.1) which utilizes a spiral screw mechanism (Figure 7.1) to fine-tune the vertical distance between the stencil and the PCB. The goal is to achieve a small, consistent gap (snap-off distance) for optimal paste release.

Figure 7.1: The steel mesh bracket incorporates a spiral screw for precise up and down height adjustment, enabling easy control over the printing gap.

7.2 Applying Solder Paste

1. Using the provided spatula or mixing knife, apply a bead of solder paste across the top edge of the stencil, just above the PCB's printing area.
2. Ensure an even distribution of paste along the width of the stencil.

7.3 The Printing Process

1. With the screen frame lowered and the PCB aligned, use a squeegee (not included, but essential for printing) to spread the solder paste across the stencil.
2. Apply even pressure and a consistent speed as you draw the squeegee across the stencil, ensuring the paste fills all apertures.
3. After one pass, lift the screen frame carefully. The solder paste should now be deposited onto the PCB pads.
4. Inspect the printed PCB for quality. The machine offers guaranteed repeatability and precision fine-tuning (Figure 7.2) for consistent results.

Figure 7.2: The printer's design ensures guaranteed repeatability, adjustable height for various PCB thicknesses, and precision fine-tuning for accurate alignment.

8. Техникалык тейлөө

8.1 Колдонгондон кийин тазалоо

• Immediately after printing, clean the stencil thoroughly to prevent solder paste from drying and clogging the apertures. Use an appropriate stencil cleaner and lint-free wipes.
• Clean any solder paste residue from the working platform and machine frame.
• Ensure all moving parts are free of debris.

8.2 Жалпы кам көрүү

• Periodically check all knobs and fasteners to ensure they are tight.
• Lubricate moving parts as needed with a light machine oil to ensure smooth operation.
• Колдонулбай турган учурда машинаны таза, кургак чөйрөдө сактаңыз.
