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?

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

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

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

Hello Folks, I am getting a Passaat SMRO-0406 reflow machine for auction. So i would like to know is this machine good or bad for doing the lead free re-flow process. The vendor said this machine is 2000 model. We wanted to do the board with size -

Thanks for your reply!! But i dont understand the 300 degree is okay to for lead free process

What do you mean by solder in ROHS. Can you please explain me little bit. Is that really important while doing lead free process. Also, please tell me wether a 8 zone (4 bottm and 4 top) reflow oven with 300 degree max.. Is good to do the lead free

Hello, So in short, i wanted to know.. for 8 zones i guess that will be a great deal. and the machine made year is 2000. Also, coming to the max. thickness of PCB we have is 0.085 inches.

I don't have one, but a lot of ovens of this vintage are on the market because they DO NOT cope well with lead free processes. There is one of these on eBay right now and it even says ROHS is right at the limit of what it can just about manage so thi
