A conversation with Phil Zarrow and Kimberly Flanagan, Technical Support Engineer.
Phil Zarrow: Kim, why would I use flux-coated preform?
Kimberly Flanagan: Indium Corporation uses a flux-coated preform instead of the more commonly used flux-cored preform. A flux-coated preform has the advantage of an oxidation barrier on the outside of the preform, whereas a flux-cored preform requires free flow in order to remove oxidation.
Phil Zarrow: What are some of the benefits of flux-coated preforms?
Kimberly Flanagan: Flux-coated preforms are solventless, so there's less voiding. They're non-tacky, so it's a hard flux coating that's fused onto the outside of the preform - and they can also come in many different colors. I've brought some pink ones here, and I brought some blue flux-coated preforms. They help the operators to distinguish different variables, so the color can help an operator determine whether it's Sn63 or SAC305.
Phil Zarrow: Kim, where can find out more information?
Kimberly Flanagan: You can go to our website at indium.com, or you can contact me directly at email@example.com.
Phil Zarrow: Kim, thank you very much.
Kimberly Flanagan: Thanks Phil.
