as a followup thought, what is your current peak reflow deg-C? and reflow timing (sec)? Au/Ni calls for reflow temperature of 217 deg-C for solder fusion that produces secondary eutectic alloy. there was one time we thought 183 deg-C was the magic

Hi, What would also be important is the time above 217. 20 secs above 225 may be the same as 45 secs above 218 That 7 degres might just buy you enough to sweep the non lead free components through Has anyone tried 220 or 218 peak temp but at lo

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

Does anyone have any experience running Aluminum Electrolytic Caps with a SAC305 alloy. The profile for the solder calls out a peak temp of 235-255C and 60-75 seconds above 217C. Most can cap manufacturers are calling out for 230-245c max for no lo

with lead-free solders, one would expect to find less instances of tombstoning. this is because SAC alloys are not eutectic and melt over a range of temp (usually 217-220 deg C) instead of at a single temperature. therefore the forces due to solder s

aj, check out the link http://www.smtnet.com/forums/index.cfm?fuseaction=view_thread&CFapp=8&Thread_id=10387&mc=5 as Samir mentioned in that link, try keeping your peak temp within 220-225degC.. TAL 217 around 20-40 sec..depending on your ball d

Tks for the answers,, My concern is about the intermetalic layer,,I run SMQ230 LEAD FREE paste.. its liquidous at 217C..the oven have 7 zone, but I run in 5 zones also with a more agressive profile (due to the line rate)..I would like to know if runn

Fellas: I'm having a tough time with voiding with my lead free water soluble paste under my large BGAs. I know some is almost inevitable, but this is more than I'd like. This is with a slope of .9, soak of 60 seconds, above 217 for 85 seco

How do the SUBJECT "CCLEF100X8M-R" and the link on your posting relate to each other? Assuming the link is important, [couldn't you find an English site posting your component?] Look here: http://www.calmicro.com/applications/app_docs/ap-217.pdf
