The SMT chip placement and sampling process is like a precision symphony performance, where various components, welding techniques, and equipment operate like melodies and rhythms in the music, while the throwing phenomenon is like a sudden dissonant note, breaking the perfection of performance. Throwing material is a common problem in SMT surface mounting process, which not only leads to resource waste, but also affects product quality and production efficiency. This article will delve deeper into the causes of material throwing in SMT surface mount sampling, helping readers better understand and solve this problem.
1. Equipment reasons
One of the common causes of material throwing is the malfunction of SMT mounting equipment.
After long-term operation, the equipment may experience component wear or aging, leading to a decrease in surface mount accuracy and even misoperation. In addition, inadequate maintenance of equipment can also increase the risk of equipment failure, leading to material throwing.
2. Material quality reasons
The quality issues of the SMT components and PCB substrates used during the SMT process may also lead to material throwing.
For example, the pins of a component may have oxidation or deformation, leading to poor soldering; Improper surface treatment or defects on PCB substrates can also have a negative impact on welding quality. Therefore, selecting high-quality components and PCB substrates is crucial for avoiding material throwing issues.
3. Reason for setting process parameters
The process parameter settings during SMT mounting directly affect the quality and stability of welding.
If the temperature, speed, pressure and other parameters of the SMT machine are not set properly, it can lead to unstable welding or component displacement, resulting in material throwing. Therefore, operators need to accurately adjust and monitor the process parameters of the equipment to ensure the stability and reliability of the SMT process.
4. Reasons for human operational errors
Human error is also one of the common causes of material throwing.
If the operator does not follow the standard operating procedures or is negligent when operating the equipment, it will increase the risk of material throwing. Therefore, for operators, standardized operation training and strict operating procedures are the key to avoiding material throwing problems.
In summary, there are multiple reasons for material throwing in SMT surface mount sampling. In response to these reasons, both SMT surface mount sampling production enterprises and operators need to strengthen training and equipment maintenance in all aspects to reduce errors in various aspects.
