In my last post, Stages of a Reflow Profile: Part I, I discussed how thespattering of solder balls and solder paste slumping can occur in the beginning stages of a reflow profile. In this post I will

Often times solder defects such as spattering, voiding, slumping/bridging, and tombstoning can be remedied just by adjusting the reflow profile. For this reason it is important to understand the

Your first consideration when determining how much flux to use in your solder wire is whether you are doing hand soldering or robotic soldering. Robotic soldering requires a greater flux percent than

Folks, Soldering copper to copper with a tin-based solder, such as tin-lead eutectic solder or a common lead-free solder like SAC305, requires only the liquid solder and copper to form the tin-copper

朋友们，可怜可怜约公元前 3500 年的冰人厄齐吧。人们认为他参与了铜冶炼，因为在他的尸体中发现了铜微粒和砷，砷是某些铜矿石中的微量元素。

In a previous post I mentioned some non-solder uses for low melting point alloys – meaning that they are used for purposes other than simply “joining two surfaces with a filler

朋友们，焊接是一项古老的技术。据估计，焊接最早发现于公元前 4000 年。因此，对凯撒大帝（公元前 100 年-公元前 44 年）来说，焊接比

Folks, Patty, Pete, Rob and the Professor were having their weekly book club meeting. As they were wrapping up, Patty said, “Remember about a month ago we talked about using an SMT Pretest

Patty was excited about today’s book club meeting with, “The Boys.” She had started calling her husband Rob, her former co-worker at ACME and now research technologist at Ivy U,

Folks, My good friends, Phil Zarrow and Jim Hall, in their award-winning audio series “Board Talk,” were recently asked about the “Five Ball Rule”. In the comments section for

Folks, Let’s see how Patty is doing, it’s been a very, very long time… Even though Patty and her husband Rob both worked at Ivy University, they seldom drove in together. It was

菲尔-扎罗罗伯特，工艺表征的行业标准是 Cpk，有时是 Cpu；拉斯基博士已经讨论过这个问题，因为它与装配工艺有关。关于材料、

I just read an article published on an SMT-focused website by Paul Socha. Mr. Socha was the Manager of Applications Engineering for many years and was instrumental in creating the group that Indium

Phil Zarrow: Eric, the topic of surface insulation resistance, SIR. What exactly is it? What are we doing here? Eric Bastow: Well, simply put you are measuring the electrical reliability of a

The tremendous increase in the use of bottom terminated components (BTCs), some estimates are at more than 50 billion per year, have heightened the concern for minimizing voiding between the thermal

Robotic Soldering II After reading my last post on robotic soldering, you have decided that you have a good robotic soldering application and want to get started. You have also decided that you will

我们之前已经探讨过低温 特别是铟基焊料。现在是时候来了解高温焊料和钎合金 了。伯尼·莱维特是我们的高级产品

Phil Zarrow: Brook, we've discussed handling solder paste from the refrigerator to the stencil printer, but there's a lot more to this story, particularly from the factory to the customer.

Most articles I have read regarding Thermal Interface Materials (TIMs) focus on one application. Others generally focus on only one material (the material the author is promoting). In the case of a

在我们关于合金 不同应用正确合金 的第一篇文章中，我们概述了低温 的一般情况，包括含铋和含铟的合金。在本篇文章中，我们将

Promation Robotic Soldering Unit Folks, There is currently considerable interest in robotic soldering, with good reason. Robotic soldering can increase productivity and profitability, but it must be
