5G (Next-Gen Communication Technology) - Passive Components and Crystal Oscillators Solving Conventional Inline Vision System Inspection Problems

As use of 5G continues to spread, the production of passive components (such as capacitors and ceramic capacitors) continues to increase, but these components face a variety of inspection problems.

  • Product miniaturisation
  • Increased production to meet greater demand
  • Compliance with stricter inspection standards

KEYENCE's Vision System technology can solve these and other problems easily.

High-Frequency Components

High-frequency components are used to transmit and receive radio waves at the required frequency.
Products designed for 4G and LTE cannot be used with 5G communication due to the different frequencies and standards, so new products must be developed.
With the increased need for product miniaturisation and the exponential increase in the number of components installed in smartphones and other devices, production lines are becoming faster than ever.

Assembly process: Counting tray-loaded chips

Problems with conventional systems

The various colours of the tray mean there is little difference between the background colour and the chips, making stable inspection difficult.

Improved inspection with multi-spectrum lighting

Accurate inspection of even minute colour variations is possible with 8-colour lighting.

Inspection process: Appearance inspection of high-frequency components

Problems with conventional systems

Stable inspection is difficult due to the low contrast of the defects detected in the target surface.

Improved inspection with LumiTraxTM

Only shape (irregularity) information is extracted regardless of surface conditions.

Ceramic Capacitors

Ceramic capacitors are used to stabilise voltage and eliminate noise in a wide range of products such as smartphones, base stations, and automobiles.
With the increased need for product miniaturisation and the exponential increase in the number of components installed in smartphones and other devices, production lines are becoming faster than ever.

Sheet formation: Appearance inspection of sheets

Problems with conventional systems

Inspection stability is hindered by the background surface conditions.

Improved inspection with LumiTraxTM

Various defects difficult to detect with conventional systems are clearly captured, ensuring stable inspection.

Inspection/packaging process: QR code and marking inspection

Problems with conventional systems

Marking is often light to prevent damage to the target, but light marking makes inspection less stable.

Improved inspection with multi-spectrum lighting

The optimal lighting colour can be selected from the 8 lighting colours, enabling clarity even with difficult-to-see marking for greater inspection stability. (UV lighting is useful for increasing marking contrast.)

Crystal Oscillators

Crystal oscillators utilise the piezoelectric effect of quartz to generate high-frequency precision oscillations.
In 5G communication technology, the oscillators are used to transmit and receive voice and information via radio waves.

Blanks formation: Appearance inspection of blanks

Problems with conventional systems

Setting an inspection area for an indefinite shape is difficult.

Improved inspection with the XG-X Customizable Vision System

The inspection area can be set according to the target shape using image calculation.
Multi-profile defect detection can also be used to detect abnormalities on the target outline.

Shape set using image calculation function (outline area)
Scratch defect extraction

Sealing process: Positioning during blanks assembly

Problems with conventional systems

Stable inspection is difficult due to the low contrast of the background.

Improved inspection with multi-spectrum lighting

LumiTraxTM mode makes it possible to ensure stable inspection with shape images.

Appearance inspection of cases (lids) is simple with LumiTraxTM shape images.

KEYENCE vision systems have become a trusted tool in manufacturing 5G components both in Japan and overseas.
Today, demand for high-accuracy, high-speed, miniaturised manufacturing and an even greater number of inspection items is on the rise.
This trend is expected to continue in the future.

This guide provides information on a variety of current inspection applications and image-based inspection of 5G-related components.
