75% on the quality difficulties in SMT creation method are linked into the printing process of solder paste printing machine. The real key factors to determine the standard of solder paste printing procedure will be the pursuing. Guangshengde solder paste printing device will share along with you

1?¡é Display cleaning of solder paste printing device

All automated solder paste printing devices are dry cleaning, damp cleansing and vacuum cleansing. Along with the growth of SMT, the hole is small as well as the velocity is fast. Several sharp points and tin on PCB are related to cleansing. The standard of automated cleaning is instantly connected to your good quality of items. The advance of cleansing function can recognize the superior performance of generation. In 2006, the domestic solder paste printing machine was enormously enhanced in cleaning. Unbiased cleansing mechanism, new cleaning principle, like highly effective suction fan vacuum adsorption system, far more uniform liquor spray program, much more effective cleaning technique, can know the benign and continual printing of finepitch.

2?¡é Impression positioning part of automated solder paste printing device

The image positioning of computerized solder paste printing device is dependent upon the positioning algorithm, which is also one in the main algorithms of computerized visual printing equipment. While using the increasing manufacturing efficiency of PCB, the electronic parts within the board are getting to be scaled-down and more compact, which places forward increased prerequisites for positioning accuracy and velocity. At the moment, the vast majority of automatic vision printing equipment positioning algorithm is predicated within the picture grey amount, through the autocorrelation matching to realize. To the copper clad plate with very good surface area uniformity, the grey algorithm can effectively finish the perform of automatic positioning. On the other hand, the looks of a growing number of tinplate, gold plate and flexible PCB brings fantastic obstacle to gray positioning. Because of to tin plating, the floor uniformity of gold-plated plate is not superb, as well as reflection charge is high, that makes the imaging brightness of mark position on PCB board enormously distinctive, and increases the wrong detection level and skipped detection charge of grey positioning. Thanks towards the bad flatness of the area of adaptable board, the graphic of mark factors on PCB will likely have got a massive big difference in brightness, and the size and form of mark points will modify. These complications are difficult to beat based mostly on grey positioning algorithm. And also the spot algorithm dependent on geometry can nicely adapt on the attractiveness of these difficulties.

As the industrial geometric positioning tools out there are more expensive, normally all-around ten thousand yuan. Taking into consideration the price things, most of the automated visible printing machines use comparatively affordable classic positioning tools primarily based on gray stage. Guangshengde solder paste printing push has adopted geometric positioning tools on all designs. Through this complex transformation, the positioning potential of tinplate, gold plate and versatile PCB board is enormously improved. In accordance with the market reflection, the right identification of current mark factors is often realized.

3?¡é Steel display screen demoulding method of automated solder paste printing machine

The demoulding high-quality of computerized solder paste printing device instantly affects the printing effect. Typically, automated visual printing device has two demoulding modes

1. "Start scraper to start with and demould later" is commonly employed, largely uncomplicated PCB board;

two. "Demoulding ahead of scraper", working with thinner PCB board, and many others;

Computerized solder paste printing machine automated solder paste printing equipment with the perspective of use: significant speed and stability could be the fundamental prerequisite. Mark position recognition of printing push is the very first element of the device: if mark point recognition is poor, mark place recognition normally happens, but manual intervention has an effect on production, and corresponding operators should be extra to enhance the use cost.
