MIS Packaging Takes Off
“AS3+ is an embedded trace (ET) coreless organic substrate that can offer some similar benefits as the C2IM/MIS solution. In addition, the AS3+/ET substrate allows for three or more routing layers where C2IM/MIS may be limited,” he said.
Molded Interconnect Subtrate
With its embedded copper trace technology, it enable a finer line and space that is needed for high I/O count with smaller form factor. It also provides a robust Flip Chip assembly process. Another important feature of MIS substrate is copper filled-via and filled-pad technologies, which is significantly important for high frequency requirements, and improve thermal dissipation.
Bridges Vs. Interposers
RDLs are measured by line and space, which refer to the width and pitch of a metal trace. In simple terms, a silicon bridge is embedded in the core of a substrate. Then, in a separate process, tiny bumps or pillars are formed on the dies. Using a flip-chip
Stripline vs Microstrip: PCB Routing Differences and …
· Like microstrip, their model is based on the trace thickness and width, and the substrate height and the dielectric type with the calculation adjusted for the trace being embedded between the two planes. Asymmetric Stripline.

For both, different physical structure options were considered – a simple trace on the substrate, a 3-D structure using vertical vias through the overmold of the SiP, and a separate 3-D antenna component contained within the SIP overmold. An iterative approach
Embedded Microstrip Impedance Calculator
Embedded microstrips are commonly crafted using printed circuit boards, although other materials can be used. An embedded microstrip can be constructed using a microstrip with a solder mask. Just enter the given values for trace thickness, substrate heights, trace width and subtrate dielectric in the calculator above and press the “calculate” button.
