Human Error in SMT and Its Causes, as well as Improvement Measures

The SMT pick-and-place machine is the main equipment used in SMT mounting processing. To ensure quality
placement, material must be properly prepared before loading into the placement machine.

When loading, be careful not to damage the equipment or material.

What Is the Cause of SMT Assembly Error?

1.Negligence:

For a number of reasons, employees can be negligent at work.

As a result of fatigue and lack rest, the alertness is reduced, making it easy to make mistakes.

Inattention can also be caused by distraction or lack attention.

When there are distractions from the outside world, the mind becomes distracted and leads to negligence.

2. Insufficient Training or Improper Training:

Lack of training and insufficient skills can lead to mistakes by employees.

This can lead to unhappy customers and even accidents.

3. Time Management Problems:

Employees can be under time pressure due to issues with time management, which increases the likelihood
of mistakes.

Employees who are pressed for time may rush through tasks without considering the details.

4.Poor Working Environment:

Unstable, noisy or crowded conditions can cause employees to lose concentration and lead to mistakes.

5. Lack of Quality Awareness:

Lack of quality awareness is one example. Other examples include insufficient quality attention, failing
to check thoroughly, or ignoring standards.

This can lead to defective products and increase the likelihood of future problems.

6. Internal Communication Problems:

Inadequate communication and unclear instructions among staff can cause misunderstandings, confusion and
errors.

To avoid errors, it is important to have a good communication system within the company and to provide
clear instructions.

Improve Strategy

1. Increase Employee Rest and Training to Prevent Excessive Fatigue

Improve the focus and concentration of employees, for instance, by providing mental health support or
training.

Standard operating procedures and clear workflows will ensure that employees do not miss important
steps.

Encourage your employees to use time management and reminder tools to help them stay focused and alert.

2. Formulate a Work Schedule and Plan

Working hours that are reasonable can help reduce the time pressure on employees.

You can reduce wasted time and use your time more effectively.

3. Provide a Comfortable Working Environment Including Proper Lighting, Ventilation and Seating

A quiet, clean and orderly work environment can help reduce environmental disturbances.

4. Establish Effective Quality Control Procedures in order to Ensure Employees are Following the
Correct Processes and Steps during Operations

Develop standard operating procedures, SOPs and quality control standards.

5. Encourage Employee Feedback and Communication

Encourage employees to continually learn and improve skills, seek feedback from them, and encourage them
to do so.

Summary

Employee errors are primarily caused by negligence, insufficient training, inadequate skills, poor time
management, a poor work environment, a lack of quality awareness and problems with internal
communication.

To improve these issues, take a number of measures, such as adequate rest, training in operating skills,
detailed production plans and a PCBA factory that is suitable, setting up quality control procedures and
encouraging employee feedback and communication.

These measures can reduce human error in SMT and improve product quality and work efficiency.

The importance of management and quality controls in SMT assembly is evident, and employees need to be
supported and trained.
