PCBA Cleaning Machine

CY-600 Offline PCBA Cleaning Machine

I. Equipment Introduction

A PCB flux cleaning equipment designed for small to medium production capacities. Featuring a typical batch cleaning process, the CY600 completes the entire process of cleaning, rinsing, and drying within a single cleaning chamber. It enhances cleaning quality, meets the cleaning requirements for various types of PCB boards, utilizes industry-standard cleaning processes, and ensures cleanliness and environmental protection.

The machine consists of a cleaning system, rinsing system, drying system, and filtration system. Powered by electricity and compressed air, the PCB boards are manually placed into the cleaning chamber. After setting the cleaning, rinsing, drying, and other relevant parameters on the touchscreen, clicking start initiates the automatic cleaning, rinsing, and drying of the PCB boards. Upon completion of the set cleaning process, the machine automatically stops and resets for the next workflow. This machine greatly facilitates operators in cleaning PCB boards, significantly improving production efficiency and quality. It is a new, high-performance fully automatic cleaning device. The equipment uses environmentally friendly water-based liquids or DI water as cleaning agents, causing no harm and posing no risk to personnel.

II. Application Areas:

Widely used in SMT communications, automotive electronics, aerospace, medical electronics, semiconductors, military research institutes, and other industries.
 

III. Process Flow:

Place PCB board → Set parameters → Heat diluted solution → Pump diluted solution to spray tank → Clean → Recover diluted solution → Rinse → Hot air drying

10. Convenient cleaning agent mixing method: Can be added manually or automatically proportioned with DI water (5%-25%).

11. Alarm提示 and buzzer design ensure operators accurately understand equipment status. In case of abnormalities, the buzzer sounds and a red light flashes, with fault information displayed textually for prompt troubleshooting.

12. Heating temperature control uses automatic PID and analog control algorithms for strict temperature deviation control and smoother temperature changes.

13. Heating sections include over-temperature protection in addition to automatic temperature control to prevent machine damage in case of accidents.

14. All motors have overload protection to effectively prevent equipment damage under abnormal conditions.

15. Transparent liquid level and markings on清洗液箱 for easy observation of level and water quality;液箱 has level sensors to ensure operation within normal levels and prevent abnormalities.

16. Machine constructed with SUS304 material for strong corrosion resistance and good temperature tolerance.

17. Hot air drying uses low-noise, high-airflow涡流 fans combined with heating elements for significantly improved drying效果.

18. All door panels are lined with soundproofing material to reduce fan noise and improve the working environment.

19. The spray chamber bottom is倾斜 designed to allow complete drainage for easier cleaning and maintenance.

V. Function Introduction

1. Operating system:

The entire system is controlled by PLC with touchscreen operation, facilitating adjustment, storage, query of various parameters, and records.

Chinese operation interface: Intuitive and简洁. Set process parameters and cleaning cycles via touchscreen. After training, operators can quickly master software programming and清洗工艺流程 operation, rapidly editing and storing multiple cleaning programs: solvent temperature setting, cleaning time setting, rinse time/frequency setting, drying time/temperature setting, conductivity monitoring, etc.

Real-time monitoring of operational data for easy data tracking and cleaning quality management.

2. Spray pump system:

5.5KW high-power stainless steel horizontal spray pump, spray pressure up to 60-80 PSI, adjustable as needed to clean PCB surfaces and component bottom contaminants, meeting lead-free soldering high-pressure spray cleaning requirements.

3. Innovative spray system with科学合理 nozzle arrangement, better suited to actual清洗工艺 requirements:

3.1 Nozzles installed horizontally, 360-degree rotation for even spraying.

3.2 Two sets of pressure喷射 systems, top and bottom, each with 12 nozzles, totaling 48 nozzles; ensuring sufficient liquid flow and eliminating cleaning dead zones.

3.3 Nozzles distributed in a gradually increasing pattern left and right, greatly enhancing cleaning capability and efficiency.

3.4 Nozzles staggered top and bottom (asymmetric) to eliminate blind spots.

3.5 Spray system equipped with pressure gauge for easy adjustment of spray pressure.

3.6 Double filtration design in the lower spray chamber filter网 effectively filters debris from清洗液 and循环 DI water, preventing pump and nozzle clogging, and greatly improving liquid usage efficiency.

4. Solvent automatic proportioning system

Utilizes the advanced German DOSATRON automatic proportioning system, which automatically mixes solvent concentrate and DI water according to the required ratio. The dilution ratio typically ranges from 5% to 20%.

6. Built-in循环 filtration system

The精密循环 filtration system effectively filters out particulate impurities like solder balls and dust剥离 from PCB boards during cleaning, maintaining the cleaning power and extending the lifespan of the recycled清洗液, reducing operating costs.

7. Built-in cleanliness detection device

After the machine automatically enters the rinse cycle, it monitors the rinse water status in real-time until the PCB boards reach the preset cleanliness, enhancing the continuity of the cleaning process.

8. Solvent recovery function:

Through software settings, before automatically switching to the rinse cycle, there is a approximately 20-second blow-dry process to effectively recover residual清洗液 from the machine chamber, pipeline walls, and pump, minimizing dilution and loss of清洗液 in the subsequent rinse cycle. This function significantly reduces清洗液 consumption.

9. Cleaning chamber temperature compensation function

In addition to the high-power heating device in the清洗液 tank, the chamber is equipped with an auxiliary temperature compensation heater. This ensures that the清洗液 remains at the activated temperature (50°C-60°C) during cleaning for optimal效果, and allows rinse water to heat up quickly for effective rinsing.
