Targeting Zero Overlook with 360° Inspection
Even metal components requiring visual inspection of whole surfaces can be inspected in 5 seconds. Defects with a depth of 0.3 mm are accurately detected.
Defects detectable with a depth of
0.3 mm or more
Issues including ironing marks, scrubbing marks, dents, pits, underfills, die attributable defects and surface roughness/unevenness with a depth of 0.3 mm or more can all be detected at high speed.
Examples of targeted components
STEP
1
Setup, adjustment
Setting of defect inspection parameters
(performed before shipment)
Our engineers preset optimal inspection parameters using defect limit products. We also offer parameter setting training, which enables operators to make the required settings themselves whenever they inspect new components after system installation.
STEP
2
Move-in & setup
SCREEN engineers also perform setup of new systems, providing customers with a turnkey solution.
STEP
3
Mass production trial
As a final step, our engineers have customers evaluate a fixed volume of target components using their system. They then use this data to perform final adjustment of parameters optimized for mass production.
Inspection
All inspection processes are performed automatically inside the system.
STEP
1
Registration of master images
Master images of approved components can be created in just a few minutes. Comparison with these masters enables even components with large tolerances to be inspected with great accuracy.
STEP
2
Loading
We are able to design automatic loaders that can handle a wide range of components as optional units.
STEP
3
Surface inspection
Components loaded into the system are automatically transferred to the first inspection unit. This unit is equipped with 17 cameras that are used to capture images for inspection. The images are then compared with the masters using our proprietary image processing technologies, enabling the detection of defects.
STEP
4
Reversal
Once image capturing is completed for components in the inspection unit, their front and rear surfaces are reversed. They are then transferred to the second inspection unit.
STEP
5
Rear Inspection
Images of the rear surfaces are captured in an inspection unit similar to that used in step 3. These images are also compared to the masters.
STEP
6
Separation and unloading
After inspection is completed, accepted and rejected components are judged and sent to their respective unloaders for discharge.
Monitors displayed inspection results
Images with detected defects are displayed in red frames
Enlarged views of defect sites
Defect areas are marked with yellow
Inspection histories are
displayed in a list view
STEP
1
Setup change
Switching of chucks
The chucks in the transfer system and inspection units are replaced.
If customers specify their component types in advance, we can design common chucks that are able to handle a variety of components .
STEP
2
Changing of parameter presets
Parameters for target components are loaded from the system’s operation screen.

SCREEN’s comprehensive
service network
The highly experienced engineers of SCREEN Group companies provide customers with optimized support from their bases located throughout the world. Lulimo users can rely on the personnel for expert assistance whenever required.
Process leading to installation
We perform inhouse evaluations of all steps from trial assessment of whether defect detection is possible right through to final installation.
Please understand that the way these evaluations are handled may change depending on the target components.
Detection of limit defects*
We first check whether the component shapes and target defects can actually be processed using our systems. If this is possible, we then ask customers to supply defect limit products and around 100 defect-free components. These components are then used to confirm zero overlook on our systems.
Live demonstration &
Facility tour
Customers have the opportunity to visit our facilities and observe the procedure as our demonstration systems perform inspection of their components.
Final decision on installation
* The smallest defects to be rejected.
