Selective flux spray machine, commonly known as programmable spray machine and selective spray machine, refers to a new environment-friendly and economical machine that sprays PCB carriers at designated positions in wave soldering process.

Research and Development Background: With the ongoing global economic downturn, electronic contract manufacturers are increasingly focusing on how to reduce production costs to increase market competitiveness. In order to meet this demand,

It is very important to change the existing production process, and the current SMT process is mature. Through analysis, it is believed that with the development of electronic technology and the need of automated production, a new type of spray is developed

System - selective spray,This programmable spray machine canA new environmentally friendly and economical machine for spraying PCB carriers at designated locations, and with the development of technology,PCB boardUp there

Using more surface mount components to reduce manual insertion has led to many issuesPCBThe plug-in area is much smaller than50%In the traditional wave soldering process, all rosin spray

Spraying the bottom of the vehicle once not only wastes a large amount of rosin and pollutes the environment, but also causes some harm to employees' bodies, which has led to an urgent need for many companies to

A new type of spray system - selective fluxSelective spray,Selective flux spray,selectivityRosin spray machine, programmable spray machine.

Installation method:selective fluxerThere are currently two main installation methods, one is an external device and the other is an embedded device. Advantages and disadvantages of external and embedded:

1 External typeselective fluxerInstalled between the wave soldering and the plug-in line, as it is not inside the wave soldering, the risk of fire is almost zero, and it is also important for the maintenance and upkeep of the machine

Very convenient

2 Embeddedselective fluxerThe spray system will be implanted into the wave soldering. This method saves space and costs relatively low, but the requirements for maintenance are very high

High temperature and poor maintenance can easily cause fires

I recommend everyone to use an external device

Usage efficiency:Take the selective spray EA-SF450 as an example, this type of selective sprayAdopting independently patented product (patent number 201220418031.5), spiral airflow nozzle, atomization effect

Strong fruit, strong penetration, equivalent atomization and penetration, no ejector pin design, compact structure. For some PCBs that are difficult to solder, our company can use dual nozzles, which greatly improves the performance

Solder quality. The company's selective spray machine is equipped with automatic nozzle cleaning function! Stability of mechanical structure operation - using independent patented structure (patent application number 201320100247.1), operation

Smooth operation. Nozzle operating mechanism - three-axis; By interpolating the third axis, it is ensured that the nozzle is spraying directly onto the solder components, thereby effectively ensuring the quality of the solder. Control system - using PC

Machine motion control card control. Multi functional, strong interface operability, with 100 programming points. It can achieve point spraying, small continuous spraying, and continuous spraying. Software Copyright (2012SR113370) 1.8m/min

The chain speed can meet the production needs of all wave soldering. These independent patented designs enable this programmable spray to achieve an average rosin content of 75% under the condition of quality assurance, which can
