The Working Principle
TRJ-401 Plus soldering process:
Feed plate → select position spray flux → select position weld → out the plate
The whole system is a closed-loop processing system.
Closed loop processing control
Feed plate → spray → preheat → welding → out plate

Description of soldering characteristics
Teljia Select Soldering has many applications and can be used conveniently in factory automation production lines. It also has several extended functions and can be used to weld a variety of mixed PCB boards either over the fixture or directly.
This material is suitable for a wide range of applications, including the design of high-performance nozzles for welding systems. It accurately and stably ejects various tin wave heights, improving the ability to continuously repeat welding in limited space or too close to parts. The welding system utilizes a welding pump, propeller, lifter, robot technology, nitrogen transportation, temperature control technology, and a unique crest nozzle to achieve high precision and minimize defective products.
The system also boasts excellent temperature control capabilities on-site, thanks to using nitrogen for welding wave crest inerting and protection. The PID temperature control principle is employed, with a 0-400 degrees range. This nitrogen-direct heat system heats the wave’s crest, and the operator can increase or decrease the temperature.
The system uses closed-loop servomotor technology for high accuracy, repeatability, and welding quality. The servo motor is an intelligent motor that maintains perfect repeatability and is guided by a ball screw and linear guide for accurate positioning, low noise, and smooth movement.
Motion control system
The system’s platform allows for easy control of running, stopping, and speed, among other attributes. The touch screen can save motion speed, temperature parameters, product count, height correction of a wave crest, and automatic width adjustment of the guide rail.
Both systems use advanced robotic control technology, specifically the closed-loop server, an intelligent motor that maintains perfect repeatability and knows its position.
The system also features a ball screw and linear guide for accurate positioning, low noise, and smooth movement.


Cam conductor Programming software
The industrial computer system offline programming software has a user-friendly interface and allows for fast programming. Programmers can convert imported scanned images or Gerber files, select solder joints, configure nozzles, and set up a selective soldering system in just a few minutes.
Additionally, the system allows for editing parameters such as starting point, welding time, moving speed, air travel speed, Z-axis height, and pump migration.
CCDVisual positioning system
The visual recognition system automatically adjusts based on the board’s offset.
The pewter height detection system
Accuracy test of tin spraying height:
To perform this test, a titanium alloy test plate is connected to a positive voltage and positioned on the side of the orbit. The plate’s coordinates relative to the origin are set in the system settings beforehand. After a certain number of products have been sprayed (adjustable), the plate will automatically move to the position of the test probe. Meanwhile, the system will gradually increase the motor speed applied to the wave peak. This will cause the spout tin wave to contact the test probe and connect the positive voltage. The system will then automatically modify and control the offset based on the measured results to achieve a stable wave.
Spray solder monitoring system
During soldering, the monitor displays real-time footage of the spray and welding situation to aid understanding.
Teljia’s specialized video software supports photo-taking and recording functions.
