Hi ​I would like to ask a questions about measure BSC package outline dimension.

100-Pin (TQFP) package have 14mm BSC dimension for size D1 and E1. After measure this dimension I have 13.82-13.84mm. 

Package with dimension D1/E1 13.82mm conform specification for 100-Pin (TQFP)?

If I measure other BSC dimension for other package, how do I know measured size conform to the package specification or not, if BSC dimension do not have tolerance?

 

Your prompt reply would be appreciated.

Hi Andrey,

 

I just got this from internal team. BSC does not have tolerance. All our POD is following JEDEC specification. For this OPN, we follow JEDEC spec, MS-026- D variance AED. Intel's representative has sent you some information through private message. Please take a look.

 

Regards,

Hi.

Private message don't answer on me question.

Can you answer the question? If I measure BSC dimension for package (D1,E1=13.82mm), how do I know measured size conform to the package specification or not, if BSC dimension do not have tolerance?

D1,E1=14mm BSC

Hi,

 

We are very sorry that we can't help that much but by following JEDEC standard, BSC has no tolerance.

According to our KDB, BSC means basic spacing between centers which has no tolerance. Apologize for the inconveniences.
