I worked for a company that had an industrial nurse come in and talk to us about lead and saftey. Basically she told us in no uncertain terms that we had nothing in the facility that would come close to producing the temperature required to have lea

With the added temperature peak associated to Lead free reflow is anyone seeing or concerned about the increased vapor pressure that may result from moisture entrapment in moisture sensitive components?

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

Yes, appropriate storage & component handling proceedures should be followed depending on the MSL (Moisture Sensitivity Level) class of the component. Some component suppliers are now marking the MSL class on the label, along with PBT (Peak Body

I presume you are looking at low melting point solders. Firstly, I would consider running BOTH sides with the same paste - this will cut down the opportunities for a mix up with rework or retro-fit. Secondly, check that there is a cored wire availabl

proper pad geometries, accurate placement, and good reflow profile. Are you having problems right now?

HI!!! its a ERSA Reflow Oven HotFLOW 7 and I really appreciate some help thanks

Hi Armando, I think you have to buy a bigger reflow let say 7 zones to get the correct profile. The reason you are getting that problem is due to short profile time. What is the size of your board? What is the composition of your solder paste? Ple

Everyone's telling you setpoints, but yet, we haven't seen a thermal profile from you. It'd help if you can provide this, and using everyone's recommended setpoints, determine if your profile is meeting: 1.)Time Above Liquidus 2.) Peak 3.) Ramp
