Protective coating is playing an increasingly important role in high-reliability PCB and PCBA manufacturing. To meet the rising demand for moisture-proof, anti-corrosion assemblies, JY Electronic Technology Co., Ltd. newly introduced a high-precision glue spraying machine. This article introduces our coating capabilities and how it improves production efficiency and product performance for global customers.
About JY – Professional PCB & PCBA One-Stop Service
Leading Manufacturing and Component Procurement
JY focuses on providing comprehensive one-stop PCB and PCBA services, including PCB fabrication, SMT assembly, and global component sourcing. Our products are widely used in telecommunications, medical equipment, industrial control, automotive electronics, and textile machinery. With Panasonic SMT lines and strong engineering support, we accept flexible orders from prototyping to mass production, starting from just 1 piece.
100% Quality Assurance
All PCB and PCBA units undergo electrical testing (E-test) and full functional testing before delivery, ensuring reliable performance for customer applications.
Why We Introduced Glue Spray Coating Technology
Growing Demand for Conformal Coating
With the market trend shifting to high-reliability electronics, more customers require conformal coating to protect PCBA from humidity, salt mist, dust, and vibration. Manual brushing was time-consuming, uneven, and prone to defects. To improve quality, JY invested in a fully automatic glue spray system.
Features of New Spray Coating Machine
- Adjustable spraying shape and glue volume
- Suitable for different viscosities of coating material
- Back-suction design to prevent dripping
- Easy cleaning and maintenance of spray chamber
- Consistent and uniform coating coverage
Application Case – Moisture-Proof PCBA for Global Customers
We received an order from an Australian client for a crane control PCB used in humid seaside environments. All components were high-end: Molex connectors, US-sourced ICs, and customized parts. To protect against moisture, the customer requested conformal coating. Manual brushing caused slow turnover and inconsistent coating, which led to our investment in the automated spraying machine.
Orders from Israeli and Canadian customers also required glue coating. The Canadian customer’s PCBA was large in size; manual brushing wasted time. After introducing the machine and multiple debugging tests, we successfully applied coating in volume production, greatly improving efficiency and coating quality.
