High-tech sorting and measurement of LED chips
You need LED chips that are precisely tailored to your application? Our customized LED chip qualification combines high-tech sorting, measurement, and special packaging—ideal for research, industry, and medical technology.
Chips 4 Light offers comprehensive, customized LED chip qualification—including precise measurement and comprehensive quality documentation for high demands.
We have the know-how and equipment needed, including controlled conditions at near cleanroom level, to transfer LED chips in single quantities from the parent wafer to customer-specific carriers such as foil, gel, or wafer packs. Mappings can be used to measure specific performance parameters. The parameters to be characterized are:
- Wavelength
- Current
- Optical power
Complete characterization
At the customer's request, each chip is individually measured, optically inspected, and documented – units outside the desired specification are specifically sorted out. This guarantees maximum quality and creates security for downstream processes such as prototyping or series production.
For this purpose, wafer mappings – the technical specifications (substrate mapping) of the individual LED chips on a wafer – are uploaded to the sorting system and then sorted.
If mapping is not available, Chips 4 Light can conduct the characterization itself on request by measuring the LED chips on the mother wafer. This allows customer-specific selections and quantities to be provided.
Optoelectronics is our expertise
- Offer of miniaturized light sources
Special requirements, for example in sensor technology or medicine, often require particularly small light sources such as point light sources. We have an idea. - Specification for your project
In our range of extensive optoelectronic components we will find the right solution for you together. - Sorting according to customer specifications
At Chips 4 Light, we have the equipment to precisely sort the required quantity in the required specification on film, gel or waffle pack with our LED chip sorters. - Long-term storage
In our dry storage cabinet we store LED chips professionally in gel- or waffle-pack for a longer period of time to support the project runtimes of our customers.
Frequently Asked Questions
Customized LED chip qualification at Chips 4 Light describes the entire process from automatic die sorting and characterization using measurement technology to long-term storage of qualified optoelectronic components. First, automated systems remove individual chips from the wafer, measure wavelength, light output, and voltage as required, and sort them into precisely fitting carriers such as foil, gel, or waffle packs.
LED chip qualification at Chips 4 Light goes far beyond simple measurement: this method, tailored to customer requirements, is a comprehensive process based on certified quality standards that takes various requirements into account throughout the entire product development process. Instead of off-the-shelf individual measurements, our customers receive a solution that is precisely tailored to their specific requirements – including complete parameter documentation, quality assurance, and project-related storage.
Using state-of-the-art technology, we record optical and electrical values not only selectively, but systematically – with tight tolerances and documented quality characteristics that precisely match the market's target specifications. Measurements are always taken under the same conditions. This allows minor deviations to be identified before they become a problem.
This form of optimized and innovative qualification is essential for demanding fields of application such as sensor technology, medical technology, or optical communication—anywhere where reliable, high-quality chips are required. Seamless quality control reduces scrap rates and risks in series production. For our customers, this means maximum reliability, lower testing costs, and measurable savings—from the initial idea to series approval.
Chips 4 Light covers an exceptionally broad wavelength spectrum – from deep UV at 260 nm to the infrared range up to 1900 nm. This means we offer LED chips, detector chips and laser diodes for almost any type of application – from biotechnology and industrial sensor technology to medical products and new developments. Whether UV, blue, green, red, white, or IR. Special wavelengths for optical electronics or spot lighting or in modules can also be realized.
Our chips can be integrated into classic housings or directly onto the circuit board – flexible, application-oriented, and in compliance with the highest quality standards. We offer not only diversity, but also tested safety. This results in high-quality, customized solutions that are precisely tailored to the technical environment and can be reliably integrated into your products.
The customer-specific LED chip characterization from Chips 4 Light is ideal for applications where maximum precision, stability, and tight specifications are crucial. Our service offers real added value, particularly in medical technology, sensor technology, automation, optical data communication, and industrial image processing.
Thanks to fully automated die sorting and precise individual measurement, our chips meet even complex specifications—for example, in LED modules for point light sources, miniaturization, or multi-channel solutions. Special designs are also possible. Applications with high requirements for uniformity, energy efficiency, or long-term stability—such as in laboratory equipment, testing systems, or medical analysis devices—benefit particularly from the quality and flexibility of our processes.
Wherever LED chips not only illuminate but also function reliably and long-term availability is required, Chips4Light is the right choice.
Qualification at Chips 4 Light goes far beyond standard distribution—we offer a comprehensive process for sophisticated electronic products. In addition to the precise selection of individual components from the wafer, each chip can be individually characterized—usually according to current, optical power, and wavelength. We have the necessary equipment and carry out thorough testing, whether by manual, optical inspection or efficient automated processes.
Our additional service for laser measurement of TO housings (CW/QCW) is unique – ideal for components where optical performance is crucial.
Long-term storage in dry cabinets with stable cooling ensures project-critical batches – an advantage when time-delayed calls are necessary. This service is virtually unique in Europe and clearly sets Chips 4 Light apart from the competition.
Are you looking for a partner who can do more than just the standard? At Chips 4 Light, you get tailor-made solutions from precise selection and professional characterization to long-term secure storage – all from a single source, all at the highest technical level. Trust in our expertise, experience, and maximum flexibility for your next generation of intelligent lighting systems. Chips 4 Light – when LED qualification becomes your product's strength, we make the difference.
