ASM E BY DEK impresora de pega rehegua

DEK E by DEK is a new generation of fully automatic high-precision solder paste printer launched by ASM Assembly Systems (formerly DEK). It is designed for modern SMT (surface mount technology) production lines and is suitable for precision solder paste printing of high-density PCBs (such as mobile phone motherboards, automotive electronics, and 5G modules). This model is further optimized on the basis of DEK TQL, providing higher speed, accuracy, and intelligent functions to meet the needs of Industry 4.0.

2. Principio de trabajo rehegua

PCB ñembohasa ha ñemohenda

The PCB enters the printing position through the transmission track, is fixed by the clamping mechanism, and the high-resolution CCD camera recognizes the Mark point for precise alignment.

Enlace malla de acero rehegua

The steel mesh and PCB are bonded by vacuum adsorption or mechanical clamping to ensure no gap (key to affect printing quality).

Impresión pasta de soldadura rehegua

The scraper (metal or polyurethane) pushes the solder paste at a set pressure, angle, and speed, and leaks through the steel mesh opening to the PCB pad.

Desmoldeo ha detección rehegua

The steel mesh is separated from the PCB (the demoulding speed is adjustable), and some models can be equipped with 3D SPI (solder paste detection) to monitor the printing quality in real time.

5. Core features

1. Intelligent scraper system

Adaptive pressure control: Automatically adjust scraper pressure according to steel mesh tension to avoid solder paste leakage or insufficient solder.

Dual scraper design: Supports one-way/two-way printing to meet different process requirements.

2. Advanced visual alignment

10μm-level CCD camera: Supports precise alignment of PCB and steel mesh, and can still be identified even if the mark point is slightly contaminated.

3D SPI integration (optional): Real-time detection of solder paste thickness and volume to prevent defective products from flowing into the patch process.

3. Fully automatic steel mesh cleaning

Multi-mode cleaning: dry wipe, wet wipe, vacuum adsorption combination to reduce solder paste residue (can be set to automatically clean after every N printings).

4. User-friendly design

Touch screen HMI: Graphical operation interface, support one-click recipe call.

Fast line change: PCB size switching fully automatically adjusts to reduce human errors.

VI. Functions and roles

1. Funciones centrales rehegua

High-precision solder paste printing: Ensure the welding reliability of fine-pitch components.

Intelligent process optimization: Automatically record printing parameters and recommend the best settings through AI algorithms.

Defect prevention: 3D SPI real-time feedback to reduce rework rate.

2. Role in SMT production line

Improve yield: Reduce welding defects such as cold soldering and bridging.

Reduce costs: Reduce solder paste waste and reduce the need for manual intervention.

Flexible production: Adapt to multi-variety, small batch orders (such as customized automotive electronics needs).

VII. Ñañangareko hagua ojeporu hagua

1. Environment and installation

Temperature and humidity control: 23±3℃, 40-60%RH, to prevent solder paste from drying.

Air source stability: The air pressure needs to be stable at 0.5–0.7MPa, and fluctuations will cause uneven printing.

2. Especificaciones operación rehegua

Solder paste management: Reheat for 4 hours + stir for 3 minutes to avoid agglomeration.

Steel mesh maintenance: Check the tension daily (≥35N/cm²) and clean the openings regularly.

Scraper maintenance: Metal scrapers are replaced every 3 months, and polyurethane scrapers are checked for wear every week.

3. Process optimization

Demolding speed: 0.3–1mm/s is recommended, too fast and easy to pull the tip.

Scraper angle: usually 45–60°, too small an angle affects the tin.
