No one can bear the "breakdown" of smt placement machine halfway, because the machine stops as soon as it stops paying. The PCB board of the ASM placement machine is like a human nerve. The components on the PCB are like human neurons. The placement head is the core and most critical part of smt pick and place machine. Its control board, the C700B of the X-axis head board, is equivalent to the brain nerve of the placement machine. Chip machine factories will face a crisis of shutdown and production shutdown.
"The last time the C700B failed, we didn't have a spare C700B. It took us three days to find the cause of the failure. Big loss. I was scared, so I came to you as soon as there was a failure this time."
Recently, Xinling Geekvalue received the customer's C700B emergency repair order, first provided the normal C700B to solve the customer's urgent need for shutdown, and then helped the customer repair the faulty C700B, successfully avoided the accident of shutdown and production stop for the customer. Considering that many customers may also encounter such problems, the editor sorted out the common faults and maintenance ideas of ASM SX1/2 V2 X-axis head board C700B, and took you to explore the truth behind the faults of C700B.
What is ASM placement machine SX1/2 V2 series X-axis head board C700B:
The X-axis head board of ASM smt mounter SX1/2 V2 series includes Modul Head Interface C700B, PCB / B-Basisadapter, VISION BOARD Spread Spectrum HCU cpl, MHCU complete compatible, Sensor module X axis 5 modules, the functions of each module are as follows:
(1) Modul Head Interface C700B: power conversion card (DC/DC)
(2) PCB / B-Basisadapter: signal adapter card
(3) VISION BOARD Spread Spectrum HCU cpl: processing image data
(4) MHCU complete compatible: inverter, DC to AC
(5) Sensor module X axis: Provide position feedback signal processing function
Common faults of ASM siplace machine SX1/2 V2 series X-axis head board C700B:
(1) Environmental factors such as high current, dust or temperature cause a short circuit, resulting in the burning of the C700B board.
(2) The working voltage is abnormal.
All DPs of the placement head cannot be powered on (DP_24V is not supplied to the placement head), and the placement head cannot be detected.
The ±15V/5V/3.3V/1.5V system core power supply voltage has no output, causing the placement head to fail to work.
The power supply is abnormal, and the MHCU and MGCU cannot establish a communication connection.
(3) The communication chip on the C7OOB board works abnormally, and the MHCU and MGCU cannot establish a communication connection.
(4) Human error in operation leads to wrong connection of cables.
ASM chip mounter SX1/2 V2 series X-axis head plate C700B maintenance ideas:
The fault of C700B is relatively easy to find. The key is to understand the control logic of C700B. After mastering its basic idea, measure the voltage of several key points to determine where the fault occurs.
(1) Whether the 40V to 24V is normal - if the voltage is not normal: ±15V/5V/3.3V/1.5V no output.
(2) Check the communication circuit - whether the IC is working normally - power-on test, input/output voltage measurement, waveform judgment.
ASM placement machine SX1/2 V2 series X-axis head board C700B hardware itself has a relatively low probability of failure. Once the C700B fails, it is easy to cause the ASM placement machine to stop production. Equipment failure will face downtime? what to do? As the gold medal service provider and solution provider of the ASM placement machine factory, Xinling Industry has proposed
(1) annual all-inclusive service,
(2) all-inclusive Azimuth skills training,
(3) Emergency maintenance and other program measures to ensure the safe and stable operation of the customer's ASM placement machine.
