The continuation of The Professor’s second visit to ACME…… “Well what should we do Professor?” John said weakly. “Clearly, not shut the line down over the lunch

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

In this report by the National Renewable Energy Laboratory (NREL), ITO (indium tin oxide) is proven to be more resistant to moisture than aluminum doped ZnO

The binary eutectic alloy of bismuth and tin (Bi/Sn) is well suited for many low temperature applications due to its melting point of 138°C, but the alloy is known for being rather brittle for a

Folks The Professor’s adventure continues: The Professor continued, “Your chipshooter is “the Herbie” in your process…” “That’s it!” a confident

Recebemos algumas perguntas sobre a utilização de metal líquido ou ligas de índio-líquido à temperatura ambiente contendo índio e gálio, e a sua reação ao aço inoxidável. Muitos cientistas estão ativamente

… and we're back now with the real situation of solder powder size and its effect on solder paste rheology. Size distribution – Real solder powder is not monodisperse (single

Folks, The day of the line balancing telecom with AJAX had arrived and Patty was nervous.She had a feeling that the meeting might be contentious. She felt some relief that The Professor would be

This week Eric Bastow offers a series of 3 entries to explain the basics of water soluble solder paste: “All these product names generally refer to a type of solder paste that leaves behind a

Folks, The adventoures of The Professor continue: In contemplating the events that transpired in the 9 months since The Professor's last visit, Patty had to chuckle.John, her boss, received

I was asked by a customer (who I consider a friend), if I had any information about formic

A well-respected colleague asked this week if the metal loading of type '4' solder powder in a paste was lower than that for type '3' because the particles were smaller. The

Dr. Andy Mackie recently put together a model to determine the probability that a componentcan besuccessfully dipped in solder paste or

A recent blog posting on Metroblogs titled, "Tin Whiskers sound harmless, don't they?" left me shaking my head regarding the association which is often made between Pb-Free Solder and
