2,000 keychain lights have been successfully delivered and received by our client 🔦

This project is a good example of how we support our customers beyond manufacturing.

While PCBA manufacturing is our core business, we also assist with related electronic product sourcing and supply chain coordination when needed.

For us, it’s not about selling products —
it’s about helping customers complete their projects more efficiently.

From PCBA to finished small electronic products, we aim to be a reliable long-term partner.

Is Manual Inspection Still Needed After AOI?

AOI (Automated Optical Inspection) plays a critical role in modern SMT assembly, helping detect defects quickly and accurately.

However, in many electronics manufacturing environments, manual visual inspection is still used alongside AOI to ensure high reliability and product quality.

At LEOONPCBA, we combine advanced inspection technologies and experienced manufacturing teams to support high-quality PCB fabrication and PCBA assembly services.

Last week I did a questionnaire survey---In SMT, every PCBA has been inspected by AOI. Is manual visual inspection still required? I also received votes from many friends.

Understanding PCB Packaging

PCB packaging describes the form and technology used to connect electronic component pins to a circuit board. It defines the component’s physical size, pin configuration, and electrical connections.

Selecting the right package type is essential for PCB design, SMT assembly, and overall product reliability.

At LEOONPCBA, we provide professional PCB fabrication and PCBA assembly services to support various component packaging technologies.

Gain insight into the diverse methods of PCB packaging, helping you make informed decisions for your project's needs.
