Indium Corporation to Feature Proven Products at SiP Conference China

Indium Corporation will feature products from its SiP portfolio at SiP Conference China, May 21, Shanghai, China.

From water-soluble solder pastes to ultra-low residue, no-clean fluxes, Indium Corporation has an industry-proven portfolio of products that meet the current and evolving challenges encountered in fine-pitch SiP applications. Those products include:

  • SiPaste® ultrafine-pitch solder paste series is specifically designed for fine feature printing with fine powders ranging from Type 5 to Type 7. They help Avoid the Void®, reduce slumps, and demonstrate consistent superior printing performance. SiPaste® C201HF is specifically formulated to accommodate fine feature printing, combining superior non-wet open performance with excellent stencil print transfer efficiency to satisfy the broadest range of process requirements and boost SPI yields. Additionally, SiPaste® 3.2HF has been adopted by leading OSATs and has been used in more than 5 billion mobile FEM SiP modules.
  • WS-446HF ball-attach and flip-chip flux is a robust, halogen-free, water-wash flux designed to provide one simple solution to complicated applications, especially those with a single cleaning step, for both ball grid array (BGA) ball-attach and flip-chip processes.
  • WS-823 ball-attach flux is a proven one-step BGA ball-attach flux designed to eliminate the costly and warpage-inducing prefluxing step, especially on Cu-OSP substrate. Its unique formulation provides excellent solderability on a wide range of surfaces, uniform pin transfer over extended periods, and low-voiding.
  • WS-829 wafer-level ball-attach flux is a water-soluble, halogen-free flux that can be used for ball-attach on substrate in a standard BGA manufacturing process (especially for the smallest sphere applications < 0.25mm) as well as wafer-/panel-level packaging.

Indium Corporation also offers a wide array of proven no-clean fluxes designed for today’s industry challenges, such as electronics devices in applications from the Internet of Things (IoT) to mobile devices and next-generation applications.
