Full Automatic Measurement For Laser Chips At A Controlled Temperature

Description of the OptoSystem Laser Diode Chip Tester VMS3100

Knowing the behavior of your chips at the actual application temperature can be hard to achieve in a fast speed manufacturing environment. This full automatic tool from OptoSystem is a masterpiece in integration of machine vision, testing equipment and chip handling know-how. Although it is used for edge emitter laser diodes, it can be custom built for other types of semiconductor chips as well. The tool automatically picks up the chip from your tape, places it on the temperature-controlled chuck and performs a full electro-optical characterization before moving it forward to the sorting stage. The measurements include the integral light output power, the spectrum and the electrical properties. You may even set an electron-absorbtion-modulator (EAM) voltage as well for data communication laser types. According to the specified criteria, the laser chips are sorted in different GelPaks or Rings. This means you can offer your chips specified at the application temperature because you have tested it.


Is it possible to handle larger frames?

The VMS3100 chip tester is designed with a supply table that handles 5 inch diameter rings or frames with 175mm inside diameter where to pick up from, but we are happy to discuss a customization for larger frames. Opto System’s tools are often a custom-made design and the we are happy to discuss with you your requirements.

Why is the testing equipment optional?

You may want to use the equipment you are used to work with. We would be happy to either propose an optional testing equipment package or work with you to integrate the testing equipment that you provide us from a third party.

How much space do I have to sort the measured laser diodes?

This is also fully customizable to satisfy your specific requirements. The standard set-up has space for four rings with inside diameter of 170mm or 16 2inch GelPaks or 4 4inch GelPaks. For the defective laser diodes we also have a trash bin.

Can I measure more than one different temperatures?

The VMS3100 is designed for only one temperature. If your volume is small and this is not something that would happen every time, you can of course re-run the measurement several times with different temperature settings. The temperature adjustment of the measurement chuck is not designed for quick temperature changes and it is not advisable to change the temperature while measuring but only between measurement lots. If you have a lot of volume and will regularly need more than one temperature testing, we recommend to use the option of having as many measurement chucks in a single tool as different temperatures that you need to measure. Check out our VMS3200 for two different temperatures and VMS3300 for three different temperatures. If that is not enoug, we will be happy to take up the challenge. Opto System has delivered testing machines with as many as 5 chucks until now!
