Hello
Everybody,
Glad to join this
forum.
This is Matthew Ma, SQE from Flextronics
SHENZHEN CHINA, I have one question about IPC/J-STD-020C. Could
you please tell me how to comprehend
"Package thickness" on page11 Table 4-1 & Table
4-2 ?
For example,we are identifing if the
peak reflow temperature can meet Pb-free process per IPC/J-STD-020C for a
Aluminum Electrolytic Capacitor. The case size of the capacitor is
Diameter 5 mm &
Length 5.4 mm,so the volume
is about 106 mm3.Then we need to know the package thickness to refer to Table
4-2 for the peak temperature.
So i am writing to ask
help:
1. If the Package thickness is
the barrel thickness of the case or not?
2. How to comprehend the package
thickness for a MLCC 0402 capacitor?
3. Is it right to identify the peak
temperature for Lead-free part as above method?
Thanks for your kinkly
help.
