In previous posts, we have mentioned soldering to gold, but never discussed the unique processing aspects related to this. Soldering to copper is straight-forward.It is done all the time and the

Folks, In teaching process optimization and failure analysis, one of the most helpful concepts is understanding he difference between common cause and special cause defects. A special cause defect,

In addition to Au/Sn sputtering pucks, Indium Corporation can also manufacture full size Au/Sn sputtering targets. 80Au/20Sn is a versatile solder that is used in a wide variety of specialty

Figure 1: Solderspatter (soldersplash) on Gold/Nickel Figure 2: Phase Inversion during Reflow Most people are aware that solder paste is a mixture of solder powder and a flux

After transferring flux, align the stencil Setup print parameters to minimize doubles and missing solder spheres Remove stencil, substrate/die should be ready for inspection and reflow Spheres can be

Folks I was chatting recently with Indium Corporation's Mike Fenner about Sn/Cu alloys for solder paste.Mike has many years of experience and I value his opinions greatly. Here is a summary of

Au stud bumped flip chip attachment? Low temperature assembly requirements? Indium is your answer… Indium can be used in many ingenious ways to attach flip chips. It can be used for solder

If you deal with indium, this is a book for you. “Phase Diagrams of Indium Alloys and Their Engineering Applications” has information about pure indium and indium

Diagram of Solder-Dipping Test Apparatus Solder-wetting Curve Interesting question from a Power Semiconductor customer this week about how to test solder paste for use in Power die-attach

Folks, Recently I caught up with Ed Briggs, a member of Indium Corporation's technical staff. I asked Ed if he would share with us his thoughts on "graping" and how to minimize it. His

Liquid thermal interface materials are available in two forms: The major difference between the two is in the temperature which these alloys become molten. Liquid metals remain molten at room

Indium Foil used as a thermal interface can easily be handled with pick and place tools. Never worked with indium foil and wondering, "What's all the hype about?" In many ways, indium

How hot are you setting your solder iron for hand soldering using solder wire or preforms? If you are cranking up the solder iron temperature because you have transitioned to lead-free solders, think

최근 제 동료 애플리케이션 엔지니어 중 한 명인 Jim Hisert가 반도체 웹사이트에 인듐 본딩과 인듐 냉간 용접에 관한 블로그를 게시했습니다. 이 주제는 두 가지 모두 자주 등장하는 주제입니다.

I recently visited a customer to help optimize a flux-less indium soldering application. They admitted they needed flux but didn’t know 1) what to use, or 2) if there was a better way to fix

This is the shape of flux deposits left after pin transfer Spheres attached after pin transfer Pin transfer is a way of selectively depositing a semi-solid or liquid material (like a solder paste or

As previously posted, Indiums Table of Specialty Alloys and Solders contains hundreds of solder alloys used as thermal interface materials and for each of them, we have listed melting temperatures.
