Common Problems and Solutions of Second Intelligent Automation Dispensing Machines in PCB Applications.

I. Project Background

As electronic products evolve towards higher integration, miniaturization, and higher reliability, the requirements for dispensing accuracy, repeatability, and process stability in the SMT (Surface Mount Technology) back-end processes of PCB manufacturing are constantly increasing.

 

Especially in the mobile phone, consumer electronics, and precision module fields, the dispensing process not only affects the appearance quality but also directly relates to the structural reliability and long-term stability of the product.

 

In actual production, dispensing quality is easily affected by multiple factors, including equipment accuracy, fluid characteristics, environmental factors, and process parameters, leading to yield fluctuations and production instability.

 

This report, based on Second Intelligent Automation’s experience in applying equipment in the PCB industry, systematically analyzes typical problems and proposes standardized solutions.

 

1. Jetting valve : Suitable for micro-dot, high-speed dispensing

2. Screw valve : Suitable for high-consistency quantitative dispensing

3.CCD vision positioning system

 

“Precise positioning + stable dispensing + process matching”

Second Intelligent Automation Equipment, through its comprehensive motion control, vision system, and fluid control technology, can effectively solve the main process problems in PCB dispensing and meet the needs of high-end electronic manufacturing.
