Hi, Thanks for the valuable feedback. We are at lower spec : ( TAL )Reflow time : Around 50 Sec ( Above 217 deg C) Peak Temp : 240- 245 deg C. Any other suspects. And your English is fine :) Regards, Ameen

Hi, Now in my wave the PCB TOP Side temperature before WAVE is 110 - 115 DegC and the Peak temp in the wave is 240 - 245. These informations are for an 63/37 Alloy. What is the PCB TOP Side temperature and the peak temperature for Lead Free Wave Sn

Hi all, What do most of you aim for when profiling BGAs ? Currently I aim for time above 60 or 70 secs but I read a report that 40 secs would be more suitable. Also peak temp - I aim for 240-245 but again this report stated 230-235. any input app

Hi, Have you checked out the BGA datasheet and see what profile is recommended for the BGA ? I use OM338 and there are dozens of recommended profiles for the Paste but you have to consider the components aswell. You state your Peak temp which I w

one of my customers with a BTU VIP 70 has the following settings, 100 / 175 / 210 / 250 / 265 with conveyor speed of 18 ins per minute. They get a peak temp of 240~245C and time above liquidus of 220 C is @ 55 secs. Built in thermocouples should give

Today's regular Sn-Pb paste chemistries are designed to run at higher peak temperatures ensuring that your lead-free alloys will coalesce with your regular Sn-Pb solder. That being said, it is do-able to solder both types in one oven. Generally, wit

The European WEEE has issued a new (5th) version of its recommendations. In it they say that , on January 1st, 2004, they will review the status of the Pb-Free issue. There is currently NO DEADLINE for implementation. As far as a direct replacemen

Last week I had the opportunity to get a sample of AIM SN100C solder paste. The SN100C paste was very nice to work with. My initial observations was that the paste had a very light odor, much less than the Alpha UP78 paste that we are currently
