VII. In-depth fault diagnosis guide

1. Fault tree analysis (taking printing offset as an example)

Possible causes:

Visual alignment abnormality (45%)

PCB positioning looseness (30%)

Insufficient steel mesh tension (15%)

Others (10%)

Diagnostic process:

Check MARK point recognition rate (should be ≥99.5%)

Test vacuum adsorption force (standard ≥-65kPa)

Measure steel mesh tension (center point ≥30N/cm²)

2. Five common fault handling

Fault 1: E205 alarm (visual alignment failure)

Handling steps:

Clean CCD lens (use special cleaning rod)

Adjust light source intensity (recommended 70-80%)

Update MARK point parameters (expand search range by 10%)

Fault 2: Solder paste pull tip

Root cause:

Excessive demoulding speed (accounting for 60%)

Abnormal solder paste viscosity (accounting for 30%)

Solution:

Parameter adjustment

1. Reduce demoulding speed to 0.5mm/s

2. Increase scraper pressure (recommended +10%)

3. Check solder paste reheating time (need ≥4h)

Fault 3: Abnormal scraper pressure

Quick troubleshooting:

Check pressure sensor wiring

Calibrate pressure zero point (need to be performed in unloaded state)

Test servo motor current (standard 1.5A±0.2)

Fault 4: Vacuum leakage

Preventive measures:

Check nozzle seal weekly

Replace vacuum filter monthly

Fault 5: System freeze

Emergency treatment:

Backup current program

Run memory test after restart (command: *#MEMTEST)

Update system firmware (need to contact after-sales)
