Joey writes: Dear Dr. Ron, I have a stencil aperture with an unusual shape. See Figure 1. How do I calculate the area ratio? The stencil thickness is 5 mils. The dimensions of the aperture are also

Cos'è il tricloruro di indio e perché è importante? Il tricloruro di indio (formula chimica InCl3), indicato anche come cloruro di indio (III) (poiché l'atomo di indio si trova nello stato di ossidazione +3) è

Il tricloruro di indio (formula chimica InCl3), chiamato anche cloruro di indio (III) (poiché l'atomo di indio si trova nello stato di ossidazione +3) è il composto di indio più diffuso dopo l'indio

At Indium Corporation, we get a lot of questions about solder paste – its composition, its application, and best practice advice.Many of those questions often involve inquiries aboutthe metal

Folks, To the SMT process engineer, the second most important thixotropic material in their lives is solder paste. If solder paste was not thixotropic, it would be difficult to print and would likely

In precedenza, in questa serie di blog, abbiamo discusso alcune delle migliori pratiche per collegare le termocoppie a una scheda a circuito stampato (PCB) per la profilatura a riflusso. Oggi, concluderò questa serie con alcune altre

In order to get an accurate reflow profile of a Printed Circuit Board (PCB), it is important to keep best practices for attaching thermocouples in mind. The first thing to remember is that a

As discussed in a previous blog post, it is important to followbest practices for attaching thermocouples to a printed circuit board (PCB) toaccurately measure the reflow profile of an assembly.

Torniamo oggi per concludere la nostra conversazione con Miloš Lazić. Se vi siete persi le prime tre parti, sentitevi liberi di tornare all'inizio qui. Jim: Cosa ti interessa di questo materiale

Yesterday, in Part 2 ofour interview, Miloš mentioned how using a hybrid solid/liquid TIM provides benefits over thermal grease. Today we discuss the challenges to working with liquid metal,

In yesterday’s post, Miloš and I discussed what he’s been working on in the

I recently caught up with Miloš Lazić,one of our Technical Support Engineers who has taken a special interest in liquid metals. In the lab, Miloš has been experimenting with and

It may seem obvious that we need dimensions on an engineering drawing to specify a solder preform, but we often receive drawings with missing dimensions or tolerances. I’m guilty of that too

Scanning Electron Microscopy (SEM) is a technique used to characterize cross sections of solder joints to identify a root cause to a soldering failure. Although there are many different detection

Quando sono stato introdotto per la prima volta al fenomeno del voiding dei QFN, sembrava un problema semplice: il degassamento del flusso crea sacche d'aria intrappolate che causano problemi di affidabilità. Ma da allora mi sono reso conto che

For the plethora of applications that require a high-melting die-attach solder, 80Au20Sn is a great choice to ensure good performance and reliability. Typical applications for 80Au20Sn in die-attach

Folks, Let’s assume your company has decided that transfer efficiency (TE) is the key metric in determining solder paste quality. Transfer efficiency is the ratio of the volume of the solder

Low-temperature solders can have a wide variety of reflow profiles. One of the great things about Durafuse® LT is that it opens up an entirely new set of options for combining low oven

Flux charring isan undesirable cosmetic defect and one of the more common issues in hand and robotic soldering operations. There are multiple factors that can contribute to the charring of flux in

Michel writes: Dr. Ron, when if comes to SMT printing of solder paste, why do some people use the five-ball rule for rectangular apertures and the eight-ball rule for circular apertures? Michel: The

When you are choosing a low temperature solder alloy, there are some key properties that you should to consider. The first, and most important, is the melting temperature.This is commonly referred to
