II. Safety Operating Procedures (Must Read)

Before operation, press the emergency stop switch, turn off the air supply (0.5~0.6MPa), and disconnect the power to the placement head.

Do not touch the ceramic/tungsten carbide surface of the nozzle tip with bare hands to avoid oil stains and fingerprints affecting vacuum and recognition.

Handle with care during installation/removal; avoid collisions with the nozzle head and suction rod.

Use only isopropyl alcohol (IPA) and anhydrous ethanol for cleaning; do not use acetone, strong acids, or strong alkalis.

Nose springs and retaining rings are consumable parts; use original parts for replacement.

III. Nozzle Installation and Removal (Depending on Model)

1. Standard Nozzle (A-type, YV/YG/YS/YSM)

Removal Steps

Emergency stop → Turn off the air supply → Move the placement head to a safe position.

Loosen the nozzle holder set screws with a 2.0mm Allen wrench (1-2 turns are sufficient; do not completely unscrew).

Gently pull the nozzle vertically downwards and place it in the dedicated nozzle box (avoid impact).

Installation Steps

Clean the mating surfaces of the nozzle rod and nozzle holder (with a lint-free cloth and IPA).

Insert the nozzle vertically upwards into the nozzle holder, ensuring the retaining spring/locking pin is in place (a “click” sound is heard).

Tighten the set screws evenly with an Allen wrench (torque 0.5-0.8 N·m; overtightening may cause deformation).

Turn on the air supply → Release the emergency stop → Perform nozzle initialization (Device → HEAD → Initialization).

2. FNC High-Speed ​​Nozzle (F-head, YV100X/XG)

Turn off the air supply → Release the FNC locking pin → Manually rotate the nozzle block to the disassembly position.

Loosen the nozzle block fixing screws → Remove the nozzle block → Disassemble the nozzle separately.

During installation, reverse the operation to ensure accurate positioning of the gear baffle and locking pins.

3. Nozzle Exchange Station Operation (YV100XG/YS12)

When returning the nozzle to the exchange station, place it in the designated direction (notch aligned).

Do not directly install the nozzle onto the placement head; it must be automatically exchanged through the exchange station to avoid damage.

IV. Cleaning and Maintenance (Core Process)

1. Daily Inspection (Once per shift)

Visually inspect the nozzle tip: No blockage, no wear, no solder paste/oil residue.

Vacuum Test: Device → HEAD → Suction → Close after 5~10 seconds. Vacuum value ≤110kPa is normal; >110kPa requires cleaning.

Rebound Test: Gently press the nozzle head with your finger; it should rebound smoothly without jamming; if jamming occurs, clean/replace the spring.

2. Deep Cleaning (Weekly, Ultrasonic Cleaning)

Required Tools

Ultrasonic cleaner, IPA/anhydrous ethanol, dedicated cleaning line (KV8-M8883-A0X), air gun, lint-free cloth, turbine oil (YAMAHA specific).

Cleaning Steps (Universal for A-head):

Disassemble the nozzle → Remove the rubber sleeve/spring → Separate the nozzle head from the rod.

Place in the ultrasonic cleaner (50℃, 5~10 minutes, IPA solution).

After removal, blow air in the opposite direction with the air gun (from the rod end towards the nozzle head) to clear the air holes.

Clean the center hole of the nozzle with the cleaning line (repeated 3~5 times) → Blow dry again with the air gun.

Cleaning the spring: Wipe with IPA → Drip 1~2 drops of turbine oil → Repeat the springing motion 5 times → Wipe away excess oil.

Assemble the rubber sleeve/spring → Vacuum retest → Reinstall in the equipment after passing the test.

F-type nozzle cleaning tips

Wash the entire nozzle block → Clean the locking pin and gears → Check for airflow obstruction → Reassemble and recalibrate the position.

YAMAHA Pick and Place Machine Nozzle Clogging/Vacuum Leakage: Common Causes

I. Common Causes of Nozzle Clogging
* Solder Paste, Red Glue, Flux Curing: Solder paste splattering after printing, and red glue/flux carbonizing at high temperatures on the bottom of components, clogging the nozzle orifice.

Component Fragments, Dust, Small Solder Balls: Cracked capacitors and resistors, PCB dust, and solder balls enter the air passage, most commonly seen in 0402/0201 models.

Dust, Lint, Oil: Workshop dust, lint-free cloth fibers, and oily fingers enter the air passage.

Aging Debris from Springs/Sleeves: Powder from internal buffer rubber rings and springs falls off and clogs the holes.

Inadequate Cleaning: Only wiping the surface, not clearing the center hole → leading to increasing clogging with use.

II. Common Causes of Vacuum Leakage in Nozzles

1. Nozzle Body Issues
* Cracks, chipping, or wear on the ceramic head of the nozzle
* Nozzle deformation or poor concentricity
* Increased nozzle orifice diameter due to wear, unable to pick up small components

2. Sealing Issues
* Aging, deformation, or damage to the O-ring/sleeve at the top of the nozzle
* Missing, reversed, or improperly installed sleeve
* Wear or scratches on the mating surface between the nozzle and the nozzle rod

3. Nozzle/Head Issues
* Wear and leakage on the inner wall of the nozzle rod
* Clogged/dampened filter cotton in the nozzle rod, leading to unstable vacuum
* Nozzle not fully inserted, loose set screw
* Aging of the air passage seal ring on the mounting head

4. Usage and Installation Issues
* Incompatible nozzle model (e.g., 30A installed on a YS machine)
* Misaligned installation, snap ring not properly engaged
* Large dimensional tolerances between different brands/aftermarket nozzles, causing leakage

III. Simplest Diagnosis: Is it a blockage or a leak? High vacuum (e.g., above -95kPa), components fall off immediately upon suction → most likely due to blockage.
Consistently low or unstable vacuum, failing to reach the threshold → most likely due to leakage.
Intermittent vacuum → wet suction rod filter/aged rubber sleeve.

IV. Quickest On-Site Solution (1-Minute Assessment)
Remove the nozzle and blow air backwards from the tail end with an air gun.
Clean the center hole with a cleaning cable.
Check the top rubber ring for damage.
Replace the suction rod filter.
Reinstall in place → Perform a vacuum test.

What are the effects of nozzle blockage or leakage on a Yamaha pick-and-place machine?

I. Direct Impact on Production (Immediately Visible)

Component Pickup Failure → Frequent Component Throwout
Unable to pick up components, unstable pickup, components fall off with slight movement
Surge in throwout rate, most noticeable with 0402/0201

Vacuum Abnormality Alarm
Equipment continuously reports: Insufficient vacuum, nozzle error, component pickup detection NG
Frequent machine stoppages, awaiting processing

Placement Misalignment, Crooked Components, Tombstoneing
Insufficient suction power → Unstable component posture → Crooked placement, skewed placement, tombstoneing
Small components are particularly prone to problems
Missing components, missing components
Nose blockage/air leakage → Completely unable to pick up components → Missing components on PCB
Numerous alarms from downstream AOI, high rework costs

II. Impact on Quality (Hidden but Fatal)

Increased Soldering Defect Rate
Misalignment → Cold solder joints, poor solder joints
Short circuits, insufficient solder, open solder joints

Component Damage
Unstable suction power → Nozzle scratches components, impacts components
Cracked capacitors, resistors
PCB Higher defect rates
Mass rework and rework
Customer complaints and high quality risks
III. Impact on costs and efficiency (most important to the boss)
Decreased production capacity
Stops, alarms, material rejection, rework
Output drops of 10% to 50% are common
High material loss
Material rejection → Waste of resistors and capacitors
Component damage → Direct scrap
Increased labor costs
Operators constantly dealing with alarms
Maintenance, cleaning, and nozzle replacement
Workload of repair personnel doubles
Shortened equipment lifespan
Nose rods, head air passages, and vacuum valves are subjected to abnormal stress over a long period
More prone to wear, aging, and malfunction
IV. Damage to the equipment itself
Increased load on the vacuum system
Accelerated wear of the nozzle rod
Premature aging of the head seal ring
Long-term damage to the vacuum valve may occur
V. Summary in one sentence
One blocked/leaky nozzle:
Material rejection ↑ → Alarms ↑ → Stops ↑ → Misalignment ↑ → Rework ↑ → Costs ↑
Production capacity ↓ → Efficiency ↓ → Quality ↓ → Profit ↓
