Flux dispensing is a critical process in robotic soldering that involves precisely applying flux—a chemical cleaning agent—onto a printed circuit board (PCB) before soldering. Flux removes oxidation and prepares the metal surfaces for a stronger, more reliable solder bond. In robotic systems, this task is automated to ensure high accuracy, repeatability, and minimal waste, especially in high-volume or high-precision electronics manufacturing.

HOW FLUX DISPENSING WORKS IN AN AUTOMATED SYSTEM
In robotic soldering, flux is applied through a micro dispensing valve system controlled by a digital controller. The robot positions the dispensing nozzle exactly where flux is needed—usually on solder pads or component leads—before the soldering tool makes contact. Depending on the setup, the system can apply micro-dots or fine lines of flux with consistent pressure and volume.
The dispensing valve (like the FCM100) does the actual fluid delivery, while the controller (such as the ST100) regulates air pressure and timing to ensure accurate and consistent dispensing. This combination eliminates the variability found in manual soldering, enhances quality control, and supports high-speed production.
FLUX DISPENSING ESSENTIALS
1. ST100 Digital Benchtop Controller
A compact and user-friendly controller, the ST100 manages the timing, pressure, and operation of the dispensing valve. This controller is a smart solution for improving dispensing efficiency and reducing fluid waste in automated processes.
2. FCM100 Non-Contact Micro Dispensing Valve
This is the heart of the dispensing process. The FCM100 delivers ultra-precise amounts of flux without touching the PCB—perfect for high-speed soldering robots.
