Panel Level Packaging based on Embedding in PWB Technology: Process and Applications

Heterogeneous integration will pass beyond current system in package (SiP) approaches. Embedding is a possible process of integrating components into high-density organic boards (PWBs). The expert session will give an insight into embedding technologies of PWBs.

Speaker: Lars Böttcher

Future electronic systems will require more and more functions that cannot be managed by a single chip, even if advanced system on chip (SoC) concepts are used. Heterogeneous integration will be the next step and will pass beyond current system in package (SiP) approaches.

Embedding is a possible process of integrating components into high-density organic boards (PWBs). Both active and passive components can be embedded in laminates resulting in thin, planar modules, which can then be stacked into 3D systems. It also allows developers to keep the inductivity between electrical connections to a minimum and provides for the integration of shielding layers.

The embedding techniques we use combine the advantages of conventional PCB manufacturing with high-precision SMT component mounting. Component assembly can be divided into two main ap-proaches: “Face down” – the chip is mounted with the bond pads facing downwards – similarly to flip chips – and “face up” – the semiconductor is mounted with the bond pads facing upwards, as in wire bonding assembly. The resulting package is similar, but the two techniques lend themselves to different applications. The “face-down” approach is already popular in series manufacturing and is particularly suited to com-ponents with small pitch. The “face-up” technique is particularly suited to the embedding of vertical components, such as power MOSFETs, IGBTs and diodes.

Key research areas at Fraunhofer IZM include developing novel techniques for embedding electronic components in PCBs, investigating new basic and packaging materials and developing new processes for manufacturing HDI substrates.

Search / advanced search of the idw archives
Combination of search terms

You can combine search terms with and, or and/or not, e.g. Philo not logy.


You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).


Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.

Selection criteria

You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).

If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
