Single Phase Semi-Auto Screen Printer Solder Paste Machine For Printing Solder Paste With Scraper

Single Phase Semi-Auto Screen Printer Solder Paste Machine For Printing Solder Paste With Scraper
 
Introduce
Semi-Automatic Solder Paste Printer is a device used to apply solder paste on printed circuit boards (PCBs). It is an important step in the SMT (Surface Mount Technology) assembly process and is used to accurately apply solder paste to the pads on the PCB so that components can be soldered to the PCB in the subsequent patch process.
 
The following is a general introduction to semi-automatic solder paste printing machines:
 
1.Equipment structure: Semi-automatic solder paste printing machines usually consist of the following main components:
Workbench: used to support and position the PCB.
2.Printing Squeegee: Responsible for applying solder paste evenly to the pads on the PCB.
3.Stencil Fixing Device: Used to fix printing stencils to ensure accurate solder paste application.
 

Specification

Features

1. The machine adopts PLC control system.
2. The machine built-in auto 4-digit counter.
3. Vertical constructure, the screen frame lift up and down verticaly by electricity, driving transversa stroke of printing head left and right action by the linear guide.
4. The screen frame can be adjusted up and down to meet the differnet height.
5. Four point stencil positioning, the printing accuracy reacy ±0.02mm,flexible stencil frame, can use different size stencil.

6, The squeegee can be adjustable, convenient for lead-free stainless steel scraper, 200-350options.

7, Flexible PIN thimble to positioning the PCB, can print the double side PCB.

8, LED touch screen can adjust the scraper speed, also use high quality HIWIN brand linear guide.

9, The scraper left and right adjustment use the Frequency converter control, can set the printing speed on the screen, make sure the printing speed is consistently, then the printing thickness more evenly.
working principle:
 
1.Preparation: Place the PCB on the workbench and adjust and position it according to the PCB size and positioning marks.
2.Stencil preparation: Place the printed stencil (also called stencil) on the stencil fixture and make sure it is aligned with the PCB.
3.Solder paste application: Start the semi-automatic solder paste printer, move the printing scraper smoothly through the template, scrape the solder paste evenly through the template holes, and apply the solder paste to the PCB pads through the openings of the template.
4.Unload the PCB: After printing is completed, remove the PCB coated with solder paste from the workbench.
 
 
Functions and features:
 
1.Accuracy and Repeatability: The semi-automatic solder paste printer has high accuracy and repeatability, ensuring even application and consistency of solder paste on the pads.
2.Adjustment and Adaptability: The printing squeegee and stencil fixture can be adjusted to accommodate different sizes and types of PCBs, as well as different solder paste thickness requirements.
3.Easy to operate: The operation of the semi-automatic solder paste printer is relatively simple. You only need to make appropriate adjustments and settings according to the PCB and solder paste requirements, and then press the start button to start the printing process.
4.Production efficiency: Compared with manual solder paste printing, semi-automatic solder paste printing machines can improve production efficiency and reduce manual operation time and labor costs.
