8 points for attention in the maintenance of ASM mounter board

ASM Mounter boards are an important part of modern electronic equipment. Once a fault occurs, timely maintenance is the key to ensuring the normal operation of the equipment. As a professional SMT maintenance engineer, we need to pay attention to some important matters to ensure the efficiency and reliability of maintenance work. This article will introduce the matters needing attention in the maintenance of the placement machine board, and provide some practical maintenance skills and suggestions.

1. Preparatory work before maintenance

1. Familiar with the working principle and structure of the placement machine board

Before repairing the board of the ASM placement machine, we need to have a deep understanding of the working principle of the placement machine and the structure of the board, and be familiar with each component and function. This helps us locate the fault point faster and accurately judge possible repair solutions during the maintenance process.

2. Collect relevant technical information and maintenance manuals

Maintenance manuals and technical data are important references for our maintenance work. Before maintenance, we need to collect and study relevant technical information to understand the fault codes, common fault points and solutions of the placement machine board. This helps us better understand equipment issues and make the right repair decisions.

2. Precautions during maintenance

1. Safety first

When performing ASM pick and place machine board maintenance, safety is the primary consideration. Make sure that the equipment is stopped and disconnected from

 the power supply to avoid electric shock and other accidental injuries. Also, ensure your own safety by using insulated tools and materials.

2. Carefully observe and record

During the maintenance process, we need to carefully observe the various components and connections of the board, and pay attention to whether there is any

 obvious damage or burnt phenomenon. At the same time, we also need to record the problems and observed phenomena for subsequent analysis and solution.

3. Use the right tools and equipment

Mounter board maintenance requires the use of some specific tools and equipment, such as multimeters, heat guns, welding tools, etc. When selecting and using a tool, 

we need to ensure that it is suitable for the specific repair task and use the correct tool operation method to avoid damaging the board or causing other problems.

4. Anti-static measures

Static electricity is one of the common causes of failure in many electronic devices. When repairing the placement machine board, we need to take a series of anti-static measures, 

such as wearing anti-static clothing, using anti-static mats and gloves, etc., to protect the board from static damage.

5. Handle sensitive components with care

There are some sensitive components in the placement machine board, such as chips, capacitors, etc. During the maintenance process, we need to handle these parts 

with special care to avoid damage caused by excessive force or wrong operation.

6. Cleaning and maintenance

After the repair is completed, we need to clean and maintain the board. Remove dust and stains generated during the repair process to ensure that the surface of the board is clean. 

At the same time, we can also carry out some preventive maintenance work, such as replacing aging capacitors or other components, cleaning fans or radiators, etc., to extend the service life of the board.

7. Testing and Validation

After the repair is completed, we need to test and verify to ensure the normal operation of the board. Functional testing, performance testing, etc. can be performed 

using testing tools and equipment to confirm whether the fix is effective.

8. Learn and update knowledge

Mounter technology is constantly evolving and updating, so we need to maintain an attitude of learning and updating knowledge. You can participate in relevant training courses, 

read technical literature, participate in industry exchanges, etc., to improve your maintenance ability and knowledge level.
