Indium Mailbag – Two Heat-Spring® Questions

  • Heat-Spring®
  • Indium

  • In today’s Indium Mailbag, we have two questions regarding the Heat-Spring® thermal interface material. The first question asks, “We're interested in testing your Heat-Spring material in an optics application. How do we get hold of a sample?”

    When we initially started offering the Heat-Spring years ago, we knew it was important to get this product into the hands of engineers and technicians. We have a few different ways for you to obtain the Heat-Spring material. The easiest is to visit our online store to purchase a Heat-Spring Kit and order a pre-packaged bundle of 0.5, 1, or 2 inch square preforms. Another way to start the process is to contact us at and discuss your needs with an Technical Engineer or Account Coordinator. This is your best option when you need a customized solution that we don’t have avaialble in the online store.

    Speaking of customization, our next question takes us way past the footprint of the larger 2” x 2” square preforms we mentioned earlier. This person asks, “Do you have a size limit on your Heat-Spring TIM?”

    This is going to be answered more completely on a case-by-case basis, but we can easily provide Heat-Springs up to 4” x 4”. If you have a larger Heat-Spring design in mind, please contact one of our Technical Support Engineers so that we can find the perfect solution for you.
