As a professional PCBA board supplier, we provide customized 2- to 32-layer PCB assembly services, focusing on providing efficient and reliable solutions for high-end household appliances such as home air conditioning control boards. 

During the PCBA assembly process, we use green solder HASL surface treatment technology, which is an environmentally friendly and economical solution, which provides good soldering performance and circuit board protection. HASL technology enhances the mechanical strength and corrosion resistance of solder joints by forming a uniform solder layer on the PCB surface, ensuring the reliability of the control board in long-term operation. 

 In short, our customized 2 to 32-layer PCB assembly service, combining inversion technology and green solder HASL surface treatment, provides a high-performance, high-reliability and environmentally friendly PCBA solution for home air conditioning control boards plan. We are committed to becoming our customers' most trustworthy partner in the field of home appliances through continuous technological innovation and excellent customer service.
