VFAT3 Packaged

This page contains all the technical data and information about the design and the test of the packaged version of the VFAT3 chip.

Organizzations Involved

• INFN - Sezione di Bari: technical management and testing,
• IMEC: design, simulations and production.

VFAT3 Package Design & Production

Design, simulations and production of the package has been assigned to IMEC (https://www.imec-int.com/en/iclink) by means of a public price enquiry. The VFAT3 packaging process has been organized into three main steps:

1. Package substrate design and simulations.
2. Prototypes production.
3. Series production.

Regarding to the first step IMEC will provide:

• Design files of the package design compatible with Cadence Allegro Package Designer (.mcm),
• An electrical analysis report including the characteristic impedance of the high-speed nets,
• A thermal analysis report of the package,
• Design guidelines for the PCB.

Package General Description

VFAT3 will be enclosed in a Ball Grid Array (BGA) package with the following specifications:

• Ball Grid Array: 20 x 20 array,
• Ball Grid Array Pitch: 0.8 mm,
• Package size: 17 mm x 17 mm,
• Package material: organic,
• Number of layers of the substrate: 4,
• Thickness of complete assembly at its thickest point: <= 1.6 mm.
