AC620

AC620 Off-line SIP/PCBA Cleaning Machine

The AC620 is an off-line SIP/PCBA cleaning machine, specially designed for the automatic cleaning of flux residues on the bottom of SIP modules and the bottom of PCBA assembled with high-precision components such as BGA, CSP and QFN. It is suitable for various flux cleaning requirements. The machine adopts a process flow of water-based cleaning fluid cleaning, DI water rinsing and hot air drying. Parameters including cleaning time, rinsing time, drying time, cleaning fluid temperature, rinsing water temperature, hot air drying temperature, rinsing times, cleaning spray pressure and rinsing spray pressure can all be set and adjusted as required. It adopts a vertical spray cleaning method, which is ideally suited for flux cleaning of PCBs with fine pitch and flip-chip devices. The machine is equipped with double tracks and two complete cleaning zones (left and right). Each cleaning zone is fitted with 4 high-pressure cleaning spray bars and 4 professional drying air knives, enabling simultaneous cleaning of 2 rows of SIP/PCBA and doubling the production capacity. It is mainly composed of a cleaning system, a rinsing system, a drying system, a filtration system and a control system.

Technical Features:

1. PC+PLC control system​ with Windows OS and a computer software interface for simple operation.
2. Equipped with two independent cleaning systems, capable of simultaneously accommodating two rows of PCBA for cleaning.
3. Comprehensive cleaning system capable of handling various types of flux.
4. Vertical spray cleaning/rinse technology​ suitable for cleaning flux from components with fine-pitch and low standoff height.
5. Independent pumps and pipelines​ for cleaning solution and rinse water to minimize cross-contamination and reduce cleaning agent consumption.
6. Real-time parameter monitoring, display, and adjustment​ for cleaning, rinsing, and drying processes via software.
7. Recirculating filtration for cleaning solution; rinse water can operate in open-loop or closed-loop​ mode (with water treatment unit).
8. Each system is equipped with four spray bars and four air knives​ arranged parallel on left and right sides, with short travel distance for high-efficiency cleaning, rinsing, and drying.
