Our breaker for hard substrates

Description of the Wafer Breaker WBS 4000

The wafer breaker from Opto System is a classic equipment that was originally developed more than 20 years ago to separate LEDs made on sapphire substrates. The machine has a cut force of up to 100kg, which effectively separates even hard substrates. It is used to separate pre-scribed substrates. The sheer yet controlled force of up to 100kg makes sure that the substrate actually separates along the intended breaking lines. It is also used when the substrates are not that hard, but when the thickness or aspect ratio of the substrate does not work with the standard cleaver or with the tape cleaver.



Why not another Breaker, like the LDH 100TSX?

The LDH 100TSX is an excellent universal full automatic breaker with an attractive price point, but it will not work if the substrates are thick, or too hard. The wafer breaker WSB4000 has just more power behind the cutter to effectively cut through thick or hard substrates. If you only need to process wafers up to 2 inches, then the LDH-50TS could be a more affordable choice. We have a lot of customers that perform all their tasks with one of those breakers just fine. All tools perform excellent at any cleaving and breaking task.

“custom half automatic operation mode”??

This breaking machine has a machine vision system, motors and sensors that allow a full automatic operation of a full wafer from beginning til end. Add the autoloader and up to 25 wafers can be processed at once.

On the other side, the breaker has also a joystick and index buttons to manually move and rotate the wafer, a monitor to see what the cameras see, and the ability to perform all tasks manually while avoiding damaging the tool unintentionally. This allows a huge flexibility when trying something out in a very efficient way, because you choose which steps should run automatically and which steps should be done manually. All these settings can be saved as a recipe as well.

Do you also sell expanders and the tape?

We do provide tape and all the required consumables to run the tools smoothly. These are materials with which we have had a positive experience for very long time. If you need to use a specific type of tape we will be happy to try it out and optimize the parameters for that specific set. We do not offer expander tools right now but we are happy to share information about possible vendors.

What are the critical process parameters?

A deep hands-on training at your location is part of our delivery. Prior to that, it is best if you contact us and send us some samples.  Our engineers will be happy as well to discuss your specific needs and share their decade long expertise with you. Besides, we are building a Wiki site to collect experiences with our tools on this website. You can consult those basics on your own right here right now!

Do you process my wafers?

Right now we do not have the capability to act as an OEM manufacturer but we are looking for partners to be able to do so in the future. If you want to try out how our tools work on your devices, please get in touch and send us some samples. We are eager to show off and learn about new applications. If you own Opto System tools and would like to offer OEM services, please get in touch too!

Can I also Process larger Wafers?

This very tool is only capable to handle 4 inch wafers, but Opto System has available modifications for the WSB4000 that are capable of handling 6″ wafers or even 8″ wafers. If you want to break larger wafers, please also get in touch with us. Opto System’s strength lays in the customization of tools for customer requirements.

Why Opto System?

Opto System’s tools are built to last and very robust with a focus on performance and quality. Opto System has been around for for more than 40 years and has earned a reputation for excellent tools in the semiconductor industry across the world.
