Scripts or commands to create the package stackup

sidm

Hi All,

are there any commands or scripts that can help to create package stack-up from scratch in an automated manner.

Something that can take in no. of conductor , dielectrics layers along with the thickness and material information and dump a tech file or mcm to be imported into SIP ?

I also wish to parametrize the package dimensions.

regards

    thanks ,is it fine to define mask as a dielectric layer ?

    For the package on package each package stack up has a solder mask for itself. So I wish to define solder make separately for them.

    Thanks , can you please also advise how can I place balls in the gap area of a POP structure (by GAP area I am referring to the air gap separating the 2 packages) ?

    you can simply add one conductor between the 2 solder masks.

    you need to make sure that the padstacks connecting the upper and lower packages have the conductor you have just added as well.

    Hi All,

    Is it possible to combine 2 sip packages through some utility instead of manual work ? 

    For example I have a 4 layer OSAT database and I need to add a different interposer database to this original 4 layer database ?

    Also can you please share any documents for doing silicon interposer design in SIP/APD ?

    regards
