Dans mon dernier article, Étapes d'un profil de refusion : Partie I, j'ai expliqué comment la dispersion des billes de soudure et l'affaissement de la pâte à braser peuvent se produire au début d'un profil de refusion. Dans cet article, je vais

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

Mes amis, pour souder du cuivre au cuivre avec un alliage à base d'étain, tel qu'un alliage eutectique étain-plomb ou un alliage sans plomb courant comme le SAC305, il suffit de l'alliage fondu et du cuivre pour former l'alliage étain-cuivre

Les gens ont pitié d'Ötzi, l'homme des glaces, qui date d'environ 3 500 ans avant notre ère. On pense qu'il était impliqué dans la fonte du cuivre, car des particules de cuivre et de l'arsenic, un oligo-élément présent dans certains minerais de cuivre, ont été trouvés dans son corps.

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

La soudure est une technologie ancienne. On estime qu'elle a été découverte pour la première fois il y a 4 000 ans avant Jésus-Christ. Pour Jules César (100 av. J.-C. - 44 av. J.-C.), la soudure était donc bien plus ancienne que la soudure à l'étain.

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, la norme industrielle pour la caractérisation des processus est Cpk, et parfois Cpu ; le Dr Lasky en a parlé en ce qui concerne les processus d'assemblage. En ce qui concerne les matériaux,

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

Nous avons eu l'occasion d'examiner les alliages de soudure à basse température et l'indium en particulier. Il est maintenant temps d'examiner les options d'alliages de brasage tendre et de brasage fort à haute température. Bernie Leavitt est notre chef de produit

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

Dans notre premier article sur le bon alliage de soudure pour la bonne application, nous avons abordé les alliages de soudure à basse température en général, y compris les alliages contenant du bismuth et de l'indium. Dans cet article, nous

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
