Indium to Feature Solder Technologies at SMTA Queretaro Expo & Tech Forum


Reading time ( words)

Indium Corporation will feature its Indium8.9HF and Indium10.1 solder pastes at SMTA Queretaro Expo & Tech Forum on July 12 in Mexico. These exceptional materials help increase reliability by allowing assemblers to avoid the void.

Indium has specifically formulated solder pastes to reduce voiding significantly below the industry average for improved finished goods reliability, while maintaining the other important process performance attributes that our customers are accustomed to.

Indium8.9HF is a no-clean, halogen-free solder paste that delivers low-voiding, as well as versatility and stability in the printing process. Under optimal process conditions, Indium8.9HF delivers excellent response-to-pause even after being left on the stencil for 60 hours.

Indium10.1 delivers our lowest voiding performance, along with excellent print transfer efficiency and response-to-pause performance. In addition, it provides robust reflow capabilities and a wide processing window, which accommodates various board sizes and throughput requirements, and minimizes defects, such as head-in-pillow and graping.

In addition, Indium will feature its “no-spatter” flux-cored wire, Core 230-RC. Core 230-RC is REACH- and RoHS-compliant, and J-STD-004B tested and compliant. It delivers an exceptionally impressive 0.09% total flux spatter, as tested per IPC TM-650 2.4.48. “No-spatter” is important to ensure that flux does not contaminate gold fingers or other contacts where it can interfere with circuit board electrical properties or spatter hot flux on operators’ hands. It is available in lead-free, tin-lead, and high-lead cored wires. Lead-free cored wire is available in diameters from 0.008” (0.2mm) to 0.125” and flux weight content from 1.0% to 4.5%.

Solder in PCBA: Can’t Live Without It... or Can We?

02/17/2020 | Joe Fjelstad, Verdant Electronics
For most of its historical use in electronics, the solder alloy of choice was tin-lead, either an Sn60/Pb40 alloy or the Sn63/ Pb37 eutectic version of the tin-lead alloy. These two alloys were the workhorses of the industry. They were both well understood in terms of their processing and reliability—that is, until the advent of lead-free, a well-meaning but ill-conceived and poorly executed conversion, forced on the industry by the European Union in 2006.
