Specificaiton:

Print-Stencil/Printing Machines for Solder Paste for Printed Circuit Board & PWB Features:

1. Scraper system

* the arch bridge is suspended straight and straight

* programmable suspension self-adjusting stepping motor drives the printing head

* four-wheel positioning sliding rail structure of bilateral double-slide block ensures the accuracy and smoothness of operation before and after scraping

* for before and after the squeegee pressure difference required and the stability of the lifting design, to prevent leakage of solder paste and blade clamping design has certain elasticity, squeegee pressure, lifting speed, the printing speed, print scope software is adjustable, and provides customers with a variety of tin under the demoulding ways to adapt to different requirements of PCB, for the customer provides a good platform for the control of printing;

* slide rail scraper system to improve operation stability and prolong service life;

Full closed-loop scraper pressure feedback device, always monitor the pressure of scraper pressure, make the lower tin more full.

2. Steel mesh positioning system

The size of steel mesh has good and wide applicability

The imported SMC cylinder is used as the cylinder.

Embedded scale, never fall off

Segmented fixed steel frame.

3. Image and optical path system

X, the Y-axis USES the Japanese black field high ground wire rod, the two ends Japan matsushita motor drive

Internal increase polaroid, automatic accurate grasping different type of the MARK point

The first machine to setup in the manufacturing process is the solder paste printer which is designed to apply solder paste using a stencil and squeegees to the appropriate pads on the PCB. This is the most widely used method for applying solder paste but jet printing is becoming more popular, especially in the sub-contract sector as there is no need for stencils and modifications are easier to make.
Keeping control of this process is critical as any printing defects, if undetected, will lead to defects further down the line. With assemblies becoming more complex the design of the stencil is key and care must be taken to ensure a repeatable and stable process.
