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.
