No meu último post, Estágios de um perfil de refluxo: Parte I, discuti como o espalhamento de bolas de solda e a queda da pasta de solda podem ocorrer nos estágios iniciais de um perfil de refluxo. Neste post eu vou

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

Pessoal, soldar cobre a cobre com uma solda à base de estanho, como a solda eutética de estanho-chumbo ou uma solda comum sem chumbo como a SAC305, requer apenas a solda líquida e o cobre para formar a liga de estanho-cobre

Pessoal, tenham pena de Ötzi, o Homem de Gelo, cerca de 3500 AC. Acredita-se que esteve envolvido na fundição de cobre, uma vez que foram encontradas partículas de cobre e arsénico, um oligoelemento presente em alguns minérios de cobre, na sua

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

Pessoal, a soldadura é uma tecnologia antiga. Estima-se que a soldadura tenha sido descoberta pela primeira vez há cerca de 4000 AC. Assim, para Júlio César (100 a.C. - 44 a.C.), a soldadura era muito mais antiga do que para o próprio

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

Phil Zarrow: Robert, a norma da indústria para a caraterização de processos é o Cpk e, por vezes, o Cpu; o Dr. Lasky discutiu este assunto no que diz respeito aos processos de montagem. Relativamente aos materiais,

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

Tivemos a oportunidade de analisar as ligas de solda de baixa temperatura e o índio em particular. Agora é altura de analisar as opções de ligas para soldadura e brasagem a alta temperatura. Bernie Leavitt é o nosso Diretor de Produto Sénior

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

No nosso primeiro post sobre A liga de solda certa para a aplicação certa, discutimos ligas de solda de baixa temperatura em geral, incluindo ligas contendo bismuto e índio. Neste post, vamos

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
