Customer specific LED Chip / LED qualification

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.
