Sembra una cosa abbastanza semplice da fare. Cosa c'è di difficile nel saldare un filo a una piazzola? Beh, sento tre comuni lamentele ed espressioni di frustrazione: POSIZIONAMENTO: in genere, in

Lasers and fiber optic waveguides can be used to activate NanoFoil®. Why would you want to use a laser to do this? It lends itself to automation: Imagine a part moving into position, the laser

Folks, In the last posting, we saw how Weibull analysis helped us to determine that SACm® lead-free solder (SAC105 with about 0.1% manganese) has comparable (actually better) thermal cycle

Derivation of the Weibull Graph Folks, Last time we introduced Weibull analysis. Let's now derive the relationships needed to calculate the slope, beta, and characteristic life, eta. F(t) is the

Due to its softness and compressibility, indium is ideal for use in creating a seal. Let's get right into it: Indium preforms are commonly used to create seals. The preforms are made into an

Folks, The Weibull distribution is arguably the most important distribution in failure analysis of leaded and lead-free solder joints. It is the first thought of someone trying to model thermal

Folks, Everyday, we are exposed to the results of surveys and polls. A typical example might be that President Obama is leading Mitt Romney in a poll by 48% to 45%, but the results are not

Here is a picture of an Indium Corporation solder flux pen, sectioned to show you the internals. Who DOESN'T want to see THAT, right?!? Flux pens are commonly used to accurately supply small

Folks, Let’s see how Patty and Pete are making out on their latest adventure…. “Here is the ProfitPro™ output,” Dave Ferris said as he pointed to a PowerPoint slide on the

Calculating the exact amount of solder paste needed for a given circuit board or for a full production run can be difficult for several reasons, including: print deposit variations paste left on the

Folks, It has been a while, let’s look in on Patty…… Patty had to admit that she was very fortunate. She had yet to turn 30 and she was a Senior Vice President at ACME. There was

Folks, There is a lot of interest in cleaning PCBs that have been assembled with no-clean solder pastes. Recently I discussed the topic with my good friend Mike Bixenman of Kyzen. Dr. Ron (DR) Mike,

It is not often that we get a request for SIR (Surface Insulation Resistance) and/or ECM (Electro-Chemical Migration) results for a water washable/soluble flux or solder paste, but often enough to

I have been asked to explain why someone would want to use rotary sputtering targets instead of planar sputtering

Folks, Some time ago I wrote a post, “In Search of Tin Whiskers,” Michael responds below. He makes some good points. Dr. Ron, I'm responding to your blog regarding tin

Vi è mai capitato di aver bisogno di una saldatura a "bassa temperatura" (cioè una lega che fonde a meno di 175C)? Potreste avere componenti delicati che non possono sopportare le temperature di rifusione standard,

I saldatori, come classe, sono metalli "interessanti". E le proprietà delle saldature contenenti indio sono eccezionalmente interessanti. Le proprietà fisiche e fisiche dell'indio (e delle leghe di indio)

Folks, Let’s look in on Patty and Pete and see how they are handling Rex “The Torrent.” Patty wanted to give Pete a little more exposure so she nodded to him to chime
