Sorry theres a mistake on previous question. It should be lead free component termination but non lead free solder alloy Sn63/Pb37. The reflow profile i am using : Soaking temp. 120 to 160 deg C; time 90 to 120 sec. Peak temp. 215 to 225 deg C; time

Indium Pb paste has always been great but the flux tends to implode on the BGA's (despite many different profile strategies). The Indium Pb-Free is horrible...horrible, and have been kicked out of my lead-free eval. PS-I went to Moonman/Guru link a

There are some RoHS BGA:s that are within the "so called" solder joint strength & reliability, that can be solder in a non LF-environment! Certaininly LF-free or RoHS BGA will sometimes work the other way around. (I know about the ball melting point)

Hi, For now we use a Specnor wave and we will by another one for Lead-Free process. We look for an other Specnor but we can have another one from Novastar Model 18FDE. Is someone work with a Novastar wave and do you have some recommandation (concer

Hi. I am trying to understand Tg and how it relates to reflow. With the higher temperatures of lead free, we have been looking toward laminates with a Tg of 180 instead of the current 140. My question is a little more general. In either lead free

Pure ignorance is my answer to that.... You're with a CM, right?? Your idiot customer probably has never stepped foot on a manufacturing floor in his entire gott-damn life, but.... he reads SMT Magazine every month, and probably read some article

I saw this MS2 in action at APEX on my friend's lead free wave during the show. Very impressive results. Appeared to simply pool in one specific location at the end of the pot...away from the wave completely...although I wasn't sure if this was due t

This stuff is great! Remember to do the maintenance correctly and you'll have great results. I've been using for about 2 months and reduced my solder purchases nearly 70% with my 63/37. I will be using the lead free version in my SAC 305 machine as s

No, but Kemet were late in adopting lead free finishes in comparison to the Japanese manufacturers, some of which have been compliant for years. The finish on Kemet Chip Caps is generally Matte Tin, & I have checked with our parent company that sell
