75% of your top quality difficulties in SMT manufacturing system are linked on the printing system of solder paste printing equipment. The crucial element factors to ascertain the standard of solder paste printing system would be the pursuing. Guangshengde solder paste printing machine will share with you

We provide construction system for digital work supervision.

Working video of computerized solder paste printing device


1?¡é Monitor cleaning of solder paste printing machine


All automated solder paste printing devices are dry cleansing, soaked cleansing and vacuum cleansing. With the progress of SMT, the hole is smaller along with the speed is quick. Several sharp details and tin on PCB are related to cleansing. The quality of computerized cleansing is directly related to the high quality of products. The improvement of cleaning function can notice the significant efficiency of creation. In 2006, the domestic solder paste printing machine was drastically enhanced in cleansing. Unbiased cleansing system, new cleaning notion, together with powerful suction fan vacuum adsorption technique, more uniform liquor spray program, much more successful cleansing system, can notice the benign and steady printing of finepitch.


2?¡é Image positioning section of automated solder paste printing device


The impression positioning of computerized solder paste printing equipment is dependent upon the positioning algorithm, that is also a single from the core algorithms of automatic visual printing equipment. With the expanding manufacturing effectiveness of PCB, the electronic factors to the board are getting to be scaled-down and smaller, which places ahead greater demands for positioning accuracy and pace. At the moment, the vast majority of automatic eyesight printing machine positioning algorithm relies to the picture grey amount, throughout the autocorrelation matching to achieve. With the copper clad plate with superior floor uniformity, the gray algorithm can perfectly total the functionality of automated positioning. However, the appearance of a growing number of tinplate, gold plate and flexible PCB provides excellent problem to gray positioning. Due to tin plating, the surface uniformity of gold-plated plate will not be excellent, as well as reflection price is large, which makes the imaging brightness of mark issue on PCB board enormously diverse, and increases the fake detection fee and missed detection fee of grey positioning. Thanks to the very poor flatness from the area of flexible board, the picture of mark details on PCB will also possess a major variation in brightness, and the sizing and condition of mark factors will change. These issues are tough to beat based mostly on gray positioning algorithm. And also the site algorithm based on geometry can perfectly adapt into the appeal of those challenges.


We provide construction system for digital work supervision.

Because the industrial geometric positioning applications in the marketplace tend to be more costly, normally around ten thousand yuan. Looking at the fee elements, the vast majority of automated visible printing devices use reasonably low-priced common positioning instruments primarily based on gray stage. Guangshengde solder paste printing push has adopted geometric positioning instruments on all styles. Via this technical transformation, the positioning capability of tinplate, gold plate and flexible PCB board has actually been greatly enhanced. Based on the industry reflection, the perfect identification of current mark points can be realized.


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


The demoulding excellent of automated solder paste printing machine straight has an effect on the printing result. Frequently, automatic visible printing machine has two demoulding modes


one. "Start scraper to start with and demould later" is broadly employed, predominantly straightforward PCB board;


From micro bit course and curriculum, learn the fundamentals of coding and programming.

two. "Demoulding in advance of scraper", utilizing thinner PCB board, etcetera;


Automated solder paste printing device automated solder paste printing machine from the standpoint of use: high speed and steadiness would be the essential need. Mark point recognition of printing push is the 1st factor from the equipment: if mark place recognition is poor, mark issue recognition generally happens, but manual intervention impacts production, and corresponding operators have to be additional to improve the use cost.
