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. 


 


 


 


 





 





Best Regards


Matthew Ma
