Guaranteed Dimension Measurement Accuracy

Measuring Base Station Antenna

5G antenna have a lot of integrated transmit and receive elements to strengthen radio waves in a specific direction and increase the reception sensitivity. The antenna emits beams from many elements. To keep them from interfering with each other, the elements and circuits must have precise shapes.

Measuring Printed Circuit Boards (PCBs)

5G devices have a lot of components, and they need to be small and thin enough to fit inside modern smartphones. They also need excellent high-frequency characteristics and the ability to withstand a wide temperature and humidity range. To help ensure that PCBs meet these strict requirements, they’re carefully inspected using a microscope.

Measuring Printed Circuit Boards (PCBs)

PCB Measurement Challenges

PCBs can be difficult to image because reflectance varies greatly, depending on the material. Without uniform brightness, measurement data may not be reliable.

Through-Hole Measurement

Through-hole measurement is a standard PCB inspection item to make sure the component is manufactured as specified. The through-hole diameter can be easily measured using OLYMPUS Stream™ software’s throwing power measurement and the BX53M or MX63 microscope.

Measuring Noise Filters

5G technology uses miniaturized noise filters whose electrodes are extremely small. Because of their small size, measuring the electrode’s size and shape requires advanced inspection equipment.

Noise Filter Electrode Measurement Challenges

Metallurgical or digital microscopes may not be able to reliably measure these electrodes due to their small size.

Accurate Electrode Measurements

The OLS5100 measuring laser microscope provides highly accurate measurements of fine electrodes with guaranteed accuracy and repeatability.

The input radio wave passes through the electrodes formed on the substrate, and the required frequency is selected and output.

Measuring Multilayer Ceramic Capacitors

Multilayer ceramic capacitors are used to suppress noise and set circuit constants in electronic devices. A large number of capacitors are required in 5G base stations and mobile terminals. The demand for miniaturization requires that the layers be increasingly thin, requiring careful inspection for quality control.

Multilayer Capacitor Measurement Challenges

Metallurgical microscopes, stereo microscopes, and conventional digital microscopes are typically used to inspect ceramic capacitors, but reflectance from electrodes and the dielectric are so different that it’s impossible to view the entire capacitor at the same time.

Accurate Multilayer Ceramic Capacitor Measurements

The DSX1000 digital microscope has features that enable you to observe the shape of minute electrodes and dielectrics with uniform brightness. And thanks to the microscope’s telecentric optical system, we can guarantee the measurement accuracy of all DSX objectives and at all magnifications.

Measuring Electronic Component Packages

The resin that wraps electronic components is called the packaging. It protects the elements and connection terminals and must also transmit signals and power. They are manufactured in a wide variety of shapes to fit various components’ blueprints. Because their fit is a critical factor, their shape must be carefully checked and measured.

Measuring Optical Fiber Core Diameters

Optical fibers are used as transmission lines since they’re not easily affected by electromagnetic noise. In 5G, multicore fiber is used to expand the transmission capacity, and the distance between each core as well as their diameter must be carefully controlled.

Measuring Optical Fiber Core Diameters

Optical Fiber Measurement Difficulties

When using a metallurgical or stereo microscope, it is often not possible to make observations with uniform brightness, leading to unreliable measurement data.

Accurate Fiber Core Measurement

The DSX1000 digital microscope makes it simple to accurately measure optical fiber core diameters and core spacing with guaranteed accuracy and repeatability.

Measuring Optical Fiber End Faces

Optical fibers are often connected to each other in a way that avoids attenuating light due to connection loss (Fresnel reflection). To prevent this, the fibers’ end faces are sphere shaped or inclined, but controlling this process can be difficult.

Measuring Optical Fiber End Faces

Fiber Optic End-Face Measurement Challenges

Measuring microscopes and conventional digital microscopes cannot accurately measure the spherical shape or inclined shape of the end face.

Accurate Fiber Optic End-Shape Data

The OLS5100 measuring laser microscope uses 4K scanning technology to capture accurate data on spherical shapes and steep slopes that are close to vertical.

Measuring Fiber-Optic Connectors

Optical fibers connect to base stations using coaxial connectors that dissipate heat efficiently, have minimal noise, and meet strict size standards. As part of the QA/QC process, the connectors are measured to make sure they meet requirements.
