We are testing SAC paste for thru-hole components in the 2nd reflow process. The solder joint is alright but some problem encountered in FR1 or CAM2 PCB after multiple times of reflow due to the temperature. We are very interested in Zn or Bi-based l

We are in the process of transitioning from OA flux to No-Clean. Because of the tighter process window there is a lot of concern about component and PCB solderability and storage. The last thing we want to do is put some solderability specification

Hello Michel...this might be a bit of a battle finding the low thermal EMF material that you are looking for. The first one that comes to my mind is Bismuth Selenium Telluride, with either a nickel or cobalt doping agent. Silver went away from this

Hi! You can choose low-temperature solder paste. The low-temperature solder paste is tin and antimony with a melting point of 138 °C. When the components of the patch cannot withstand the temperature of 200 ° C and above and the patch reflow process

I will start with the statement that I think it is great that we have the ability to solder SMT components that emulates wave soldered components. With that in mind, I would want to find acceptance criteria to be similiar, regardless of the solder me

Immersion Silver, ImAg, is becoming the finish of preference. This is due to it having similar process limits vs. SnPb HASL. There were some early concerns about shelf life, but new chemistries have extended finish shelf life to 12 months+. Many boar

Hello Reese, Lifted leads are and have always been a big concern for us. We were using a system that had 12 cameras total. 8 angled and 4 top-down. I could not get that to catch lifted leads without having a ton of false calls. I thought that may

We're not sure what you mean by temperature sensitive components. From an assembly process stand-point, every component we use is temperature sensitive to one level or another. More specifically, some of our products use polyphenylene sulfide (PPS)
