Evaluation & Analysis

CDK offers wide range of evaluation and analysis to meet our customers' needs.
We provide the immediate & flexible service such as electrical measurement, visual inspection (x-ray, SEM, EDS…), chemical etch and so on.

Observing Equipment

Stereomicroscope

Purpose	Expanding the observation image by stereomicroscope.
Method	Magnification rate X 7 to 90 Lighting Ring type / Coaxial lighting type *Polarization observation(λ/4) is possible by using the coaxial lighting.
Equipment	OPTIPHOT 150 (NIKON) ,etc.

Metallograph

Purpose	Expanding the observation image by metallograph.
Method	Magnification rate X 20 to 5000 Lighting Coaxial lighting type
Equipment	SZX12 (OLYMPUS) ,etc.

Digital Microscope

Purpose	Expanding the observation image by digital microscope.
Method	Magnification rate X 20 to 5000 Lighting Ring type / Coaxial lighting type
Equipment	VHX-500 (KEYENCE)

Measuring Equipment

Laser Microscope

Purpose	Observing the image by scanning the laser.
Method	Depth resolution 0.01 um Width resolution 0.01 um
Equipment	VHX-8710 (KEYENCE)

X-ray Fluorescence Thickness Meter

Purpose	Measuring thickness and elemental ratio of films.
Method	Ag/Cu Ag/Ni Au/Ni
Equipment	XDVM-W (FISCHER)

Inside Inspection

X-ray Analysis Equipment

Purpose	Taking the fluoroscopic image to observe the inside.
Method	Tube voltage MAX 90 kV Tube current MAX 0.1 uA Table size 250 X 330 mm
Equipment	WL-90 (SOFTEX)

IComponent Analysis

SEM／EDS

Purpose	Taking the image and analyzing the component.
Method	Acceleration voltage 0.5kV to 30kV Minimum resolution 4.0 nm Stage size 80 X 40 mm
Equipment	SEM:JSM-6380(JEOL) EDS:JED-2300(JEOL)

ex)component analysis by EDS: interface of solder

Device Processing

Ion Milling

Purpose	Polishing the surface of the device by noble gas beam.
Method	Acceleration voltage 2kV to 6kV Beam diameter from 500 um/li Sample size 11 X 10 X 2 mm/li *As processible size is tiny, it may be necessary to do precutting.
Equipment	IB-09010CP (EOL)

Chemical Etching

Purpose	Etching the plastic package by using mixed acid.
Method	By difference of plastic composition, the state of dissolving is different. so it may be necessary to do pretest. Please ask us in advance.
