How do PCBA manufacturers handle small components such as 0201?

The miniaturization of electronic products has brought challenges to handling extremely small components such as 0201 in PCBA. The size of 0201 components is only 0.6 mm * 0.3 mm, and the extremely small size is very difficult to place, inspect and solder. We will explore how PCBA manufacturers overcome these challenges.

The miniaturization of electronic products has brought challenges to handling extremely small components such as 0201 in PCBA. The size of 0201 components is only 0.6 mm * 0.3 mm, and the extremely small size is very difficult to place, inspect and solder. We will explore how PCBA manufacturers overcome these challenges.

0201 components are very small and cannot be handled manually. They are prone to misalignment and tombstone effects, as well as accidental loss. In addition, soldering 0201 components is very strict. Even a slight misalignment can cause short circuits in high-density designs.

Of course, PCBA manufacturers also have corresponding solutions:

1. High-precision placement machine

The latest high-precision placement machine can handle components as small as 01005. The machine has a high-resolution camera. The vacuum nozzle is specially designed for small components and can accurately place 0201 components on the PCB at a speed of thousands per hour.

2. Specialized soldering techniques

Thinner stencils: Use stencils with thicknesses of 0.1 mm to 0.12 mm to deposit the right amount of solder paste.
Smaller apertures: The apertures are designed to match the tiny pads of 0201 components.
Fine-pitch solder paste: Use type 4 or type 5 solder paste with smaller particle sizes to ensure smooth deposition.

3. Automated optical inspection (AOI)

The small size of 0201 components makes manual visual inspection difficult. AOI with high-resolution cameras can detect defects in small 0201 components.

4. Dust-free manufacturing

Anti-static measures: Grounded workstations and equipment protect components.
Temperature and humidity control: Maintaining optimal temperature and humidity levels can reduce static electricity accumulation.
Dust-free environment: Use a Class 1000 dust-free workshop to prevent contamination.

Conclusion
Today, by mastering the handling of small components such as 0201, 01005, smaller and more powerful electronic devices can be achieved.
