Hi,

I am using the IPC 7351 LP Viewer Version 7.03.00 to ascertain the
Solder Land Patterns of Chip Type Resistors in my PCB design. 

 

I have the following query -

The Viewer shows the following dimensions for Vishay and Panasonic
respectively.

Vishay RESC0603X28N:        Pad X= 0.40, Pad Y= 0.45, Pad Space C= 0.70

Panasonic RESC0603X30N: Pad X= 0.40, Pad Y= 0.45, Pad Space C= 0.70

 

However based on the component datasheets specs I work out the following
dimensions.

Vishay 0603: Pad X= 0.50, Pad Y= 0.9, Pad Space C= 1.5

Panasonic 0603: Pad X= 0.65, Pad Y= 0.9, Pad Space C= 1.45

 

Can someone please help me clarify my query?

 

Regards,

--Tushar
