Vehicle-mounted light-emitting component inspection [Easily establish optical characteristic testing]

Vehicle-mounted light-emitting component inspection [Easily establish optical characteristic testing]

Simultaneous inspection of the optical characteristics and appearance defects of light-emitting components using a hybrid of a 2D luminance meter and a high-resolution camera!

As the performance of automotive lighting components evolves, accurate measurement of their optical characteristics is increasingly required. Uniformity of brightness and color, improved visibility, and verification are crucial factors directly linked to driver comfort and safety. Tekunos Co., Ltd. offers inspection solutions that easily enable brightness and color measurements and inspections using 2D luminance meters. You can implement inspection systems that match your production processes at a low cost. Additionally, in cases where the resolution of the 2D luminance meter is insufficient, hybrid inspections using high-resolution cameras allow for the detection of minute foreign objects and pinholes. The system is equipped with automatic recognition of misalignment of light-emitting marks and an automatic tracking function for measurement spots, accommodating various inspections required in the manufacturing process. Leveraging years of experience and know-how, we strongly support your production processes. *For more details, please download the PDF or feel free to contact us.

[Inspection Case] Lighting and functional inspection of LCD modules from overseas manufacturers.

[Inspection Case] Lighting and functional inspection of LCD modules from overseas manufacturers.

Defective LCD modules from overseas manufacturers. Sorting inspection using jig computers. Solving issues domestically without sending them overseas, reducing transportation costs and ensuring short delivery times!

We would like to introduce a case study of problem-solving involving the inspection of LCD modules for lighting and functionality. Our client requested an inspection using lighting fixtures and computers because defects were discovered in the LCD modules manufactured overseas upon delivery. To respond promptly, we coordinated with other departments and implemented overtime as necessary. We managed product lot control and provided daily inspection performance reports. The urgently needed quantities were directly shipped to the specified destination via a charter service arranged by our company. As a result, the procedures and costs for sending the products overseas were eliminated, and most importantly, we were able to meet the production line deadlines without delay, for which we received great appreciation. Additionally, we heard that the client was pleased that the issue did not escalate into a major problem and was resolved. 【Proposal Case (Partial)】 <Problem> ■ There was no time to spare for re-delivery due to the sudden discovery of defects. ■ Issues with transportation procedures to overseas. <Proposal Content> ■ Ship the inspected items in boxes as they are completed via charter service to the client. <Result> ■ We managed to avoid difficulties by meeting the production line schedule. *For more details, please refer to the PDF document.

[PCB Circuit Design and PCB Assembly] Regarding Non-measurable Components

[PCB Circuit Design and PCB Assembly] Regarding Non-measurable Components

There are many combinations that become impossible to measure! Compare the implementation value with the reference value and make a judgment.

This document contains information about components that cannot be measured. Since we are inspecting components within a circuit rather than individual parts, there may be cases where inspections cannot be conducted due to surrounding influences. Examples of components that cannot be measured are also included, making it a useful reference. We encourage you to read it. [Contents (excerpt)] ■ Board mounting, quality, technology ■ Components that cannot be measured *For more details, please refer to the PDF document or feel free to contact us.

Lighting solutions for solving issues in appearance inspection! Inspection of resin parts with glossy paint treatment.

Lighting solutions for solving issues in appearance inspection! Inspection of resin parts with glossy paint treatment.

To reduce the burden on workers in visual inspections. Adoption of LEDs that take circadian rhythms into account.

The "Light Board VS Series" is an inspection lighting that uses the LED "Vitasolis," which emits a natural white light by suppressing yellow light and containing a significant amount of blue-green light. By enhancing the spectrum around 480nm (blue-green region), it increases the melanopic illuminance that promotes serotonin secretion by more than 10% compared to our conventional products, contributing to improved work efficiency through the enhancement of the circadian rhythm. 【Features】 ■ Reduces the burden on workers with a wide spectrum ■ Emits a clear white light by suppressing yellow light ■ Contributes to the improvement of EML, which is an indicator of WELL certification ■ Supports the efficiency of visual inspection processes and reduces mental and physical stress *You can view materials introducing the evaluation results of the LED through PDF download. Please feel free to contact us.
