From December 3 to 5, 2025, the 2025 China Shenzhen International Electronic Circuit Exhibition convened at the Shenzhen World Exhibition & Convention Center (Bao’an). As a flagship industry event covering the entire industrial chain of “design-manufacturing-equipment-materials-application,” the exhibition attracted over 350 premium exhibitors and more than 40,000 professional visitors, collectively exploring the technological innovation and green upgrading pathways of the PCB industry in the AI era. BSK made a prominent appearance with its custom-developed pneumatic diaphragm pumps tailored for PCB equipment, delivering targeted solutions for critical links such as wet processes and waste liquid treatment in PCB manufacturing. Leveraging core advantages of corrosion resistance, leak-proof performance, and high precision, BSK emerged as a standout highlight of the exhibition.
Targeting Core Pain Points in PCB Manufacturing, Custom Solutions Gain Strong Traction
Wet processes in PCB manufacturing—including etching, developing, copper plating, and stripping—involve frequent conveyance of corrosive media such as strong acids, alkalis, and particle-containing waste liquids. Manufacturers are confronted with three pivotal challenges: environmental compliance, product precision control, and production continuity. Traditional conveying equipment often suffers from corrosion-induced leakage, clogging-related downtime, and chemical contamination, which not only reduces production efficiency but also elevates operational risks, failing to cater to the manufacturing requirements of high-end products such as high-multilayer PCBs and high-frequency boards for automotive electronics.
To address these industry-wide pain points, BSK’s pneumatic diaphragm pumps have achieved three core technological breakthroughs:
1. Optional Wetted Component Materials for Versatile Chemical Compatibility
Key wetted components of the pumps are available in optional materials, including 316L stainless steel and PTFE (polytetrafluoroethylene), allowing customization based on the specific corrosiveness of PCB production media. These materials enable the pumps to withstand common aggressive substances such as etchants, developers, and strippers, while adapting to fluid conveyance across a pH range of 0-14. This flexible material selection effectively addresses longstanding challenges of traditional equipment—including leakage and shortened service life caused by inadequate corrosion resistance. The pump variant optimized for PCB cleaning processes features a modular fluid channel structure, ensuring efficient conveyance of particle-containing waste liquids while eliminating clogging hazards.
2. Leak-Proof & Low-Shear Design: Safeguarding Precision and Compliance
Adopting a sealed diaphragm isolation structure, the pumps fully separate the conveyed medium from drive components, achieving near-zero leakage performance. This minimizes VOCs emissions resulting from chemical volatilization, ensuring compliance with relevant environmental standards. Meanwhile, the low-shear pneumatic drive technology maintains the integrity of chemical compositions, preserving the purity of process fluids for etching and copper plating. This not only enhances PCB circuit precision and product yield but also proves particularly suitable for the manufacturing of AI-driven high-multilayer PCBs.
3. Flexible Adaptability to Full-Process PCB Equipment
BSK pneumatic diaphragm pumps can seamlessly integrate into PCB production lines, including etching machines, developing equipment, copper plating systems, and waste liquid recycling units. Flow rates can be precisely regulated via air pressure adjustment, accommodating the full range of process requirements—from raw material conveyance and process fluid circulation to centralized waste liquid treatment. Their compact structure and safety-optimized design adapt seamlessly to the upgraded layout of intelligent PCB factories, ensuring compatibility with automated control systems.
Immersive Experience & In-Depth Communication: Forging Solid Cooperation Bridges
BSK’s exhibition format, combining “physical demonstrations with scenario-based solutions,” drew a multitude of PCB equipment manufacturers and circuit board producers. In the interactive demonstration zone, staff simulated the circulation and conveyance of PCB etchants, intuitively showcasing the stable operation of BSK pumps in highly corrosive environments. Their clogging resistance and low-noise performance garnered widespread acclaim from on-site visitors. Targeting the personalized needs of niche segments—such as high-multilayer PCBs and automotive electronic PCBs—BSK’s technical team provided one-on-one consulting services, optimizing conveying solutions based on individual enterprise production processes and securing several preliminary cooperation agreements.
Aligning with Industry Trends, Jointly Building a Sustainable PCB Ecosystem
Currently, the PCB industry is evolving toward three core directions: AI-driven design optimization, green manufacturing, and high-frequency performance enhancement, which imposes higher requirements on the reliability, environmental friendliness, and compatibility of supporting equipment. With years of technical accumulation in the fluid conveyance field, BSK continuously iterates its products to meet the evolving needs of the PCB industry. Its pneumatic diaphragm pumps hold ISO9001 quality management system certification and have reached advanced industry levels in terms of material compatibility and flow control precision.
Through its participation in the 2025 China Shenzhen International Electronic Circuit Exhibition, BSK not only showcased its core products supporting PCB equipment but also conducted in-depth exchanges with industry leaders in the PCB sector on topics including technological innovation and industrial chain collaboration, laying a solid foundation for future cooperation. Moving forward, BSK will continue to focus on technological innovation, launching more customized products for high-end PCB manufacturing and empowering the electronic circuit sector to achieve efficient, green, and intelligent upgrading.
