After just finishing her department’s monthly activity report, Patty took a break to stare out of her window, admiring the beauty of last night’s fresh snowfall.Her mind quickly went to

The use of gold layers deposited onto nickel is standard in many industries, from DRAMmemory module edge connectors, to electrical test probe contacts, to power semiconductor die metallizations and

一般に、相変化材料とは、固体から液体へ、あるいは液体から固体へと相変化するときにエネルギーを貯蔵または放出する材料のことである。

Folks, While at SMTAI a few weeks ago, I ran into Patty.She agreed to sit down for an interview.Here it is. Dr. Ron (DR): Patty, it’s great to see you here at SMTAI.Congratulations on your

As a supplier of electronics materials, Indium Corporation is constantly faced with customer requests for “halogen-free” (HF) soldering fluxes and associated materials. This is an interesting

If you’re a reader of this blog, you most likely deal with solder paste, flux, or some other messy material. How can you keep these materials off of you working surfaces? Step 1) Clean before

Had some very interesting conversations at the IWLPC show last week, as always: one discussion was with my good friend Jeff Schake of

Folks, The adventures of Patty and The Professor continue….. Patty and The Professor agreed to work with two of the local process engineers to develop a plan of attack to try and find the lost

Folks, Business was good at ACME. Even in these challenging times, the company’s three assembly lines could not keep up with demand. John, the manger of the assembly lines, decided to request

Once the flux has been formulated and scaled up it then must be mixed with solder powder. The mixing procedure and equipment must be capable of providing a homogenous product batch after batch after

The second main ingredient in solder paste is the flux (vehicle). Flux is a very complex group of chemicals/materials that must be able to do a number of things, some of which must happen

Eutectic Gold Tin (AuSn) with a composition of 80Au20Sn is a unique material. This particular alloy of gold tin (AuSn) is considered a solder because it has a melting temperature of 280ºC, which

Much to the surprise of the SnPb and SAC alloy consuming world, there are a number of alloys available in solder paste, each with their own unique melting points and soldering and mechanical

Materials to be used in packaging of high power semiconductor devices are often chosen by their coefficient of thermal expansion, or

Folks, Recently, I ran into The Professor. He graciously agreed to an interview. The following is the discussion from our meeting. Note: I was a student and mentee of his in the ‘70s, hence he is

After you've reflowed solder in contact with a flux, you're always left with a certain amount of flux residue. There are no clear industry guidelines on how you refer to the residue, and new
