Three classifications of solder paste printing machines

Solder paste is widely used in solder paste printing, and solder paste printing is generally divided into three categories.

Manual Solder Paste Printing Machine

Manual solder paste printing machines are the most basic and cheapest.

PCB pick and place, solder paste placement, squeegee scraping printing, all manual operation. Printing quality, PCB alignment stencil all need the experience and technical support of the operator, under a certain technology, to ensure that almost every piece of PCB consistent printing quality. For the time being this printing technology is outdated, inefficient, low quality and unable to keep up with current productivity. Manual solder paste printers are generally used for small-scale processing.

1. T screw rod regulating handle, ensure adjustment accuracy and levelness of PCB fixed plane, minimum lead pitch achieved 1mm.

2. Adjustable rubber footing, ensure the flatness while operating.

3. Letter mark for each regulating handle, better and easier to operate.

4. Rulers of stencil fixed frame for reference lines, ensure the levelness between stencil and PCB.

5. Straight damping shaft, ensure the stencil fixed frame can be fastened at random angles, to improve convenience while operating.

Semi-automatic solder paste printing machines

The semi-automatic solder paste printer is the most widely used machine for solder paste printing.

Semi-automatic is reflected in the fact that PCB pick and place is dependent on manual, but the squeegee operation of the solder paste printing machine is regulated by equipment parameters and automated printing. The printing quality and productivity of this equipment is much greater than that of manual printing. The control of the equipment solves to a certain extent the problem of inconsistent printing quality. The angle, pressure, speed and distance of the squeegee can all be adjusted to achieve the best printing results all over again.

1. PC control, touch screen display and menu operation interface.

2. Floating scraper. similar to automatic printer, the scraper can be floated freely up and down and can be adjusted automatically to level with the steel grid.

3. The pressure of the scraper is adjustable. The pressure of the scraper on the steel grid is adjustable according to the length of the scraper.

4. The process of the stell gird removing from the PCB can be adjustable from 0 to 5seconds.

5. Use both of your hands to press the button to operate so that the safety and reliability are ensured.

Automatic solder paste printing machine

with the advent of the 5G Internet of Things, fully automatic solder paste printing machines are slowly becoming more widespread and many manufacturers are switching to fully automatic solder paste printing machines. Fully automatic as the name implies, all operations are completed by the equipment, the operator to adjust the parameters, the equipment is all automated to complete production. But this need to start using a few test pieces to see the quality of printing, there are problems need to improve the parameters to allow the quality of standards before starting production, this equipment is the most efficient, but the initial cost is also high.

1. Four way light source is adjustable, light intensity is adjustable, light is uniform, and image acquisition is more perfect;Good identification (including uneven mark points), suitable for tinning, copper plating,Gold plating, tin spraying, FPC and other types of PCB with different colors.

2. Intelligent programmable setting, two independent direct motors driven squeegee, built-in precise pressure control system.

3. The platform height is automatically calibrated according to PCB thickness setting, which is intelligent, fast, simple and reliable in structure.

4. The scraper Y axis adopts servo motor drive through screw drive,to improve accuracy grade,operational stability and extend the service life,to provide customers with a good printing control platform.
