LPKF Delivers First AMP Laser System for Volume Manufacturing of IC Packages
October 8, 2020 | LPKFEstimated reading time: 2 minutes
LPKF’s Active Mold Packaging (AMP) technology enables electrical circuits directly on the surface and inside the volume of the epoxy mold compound. This contributes to cost and space savings in advanced packaging manufacturing, and to a higher functional density of finished ICs. In addition, AMP helps to reduce power consumption, improves heat dissipation for power applications, enables additive 2L EMC-RDL formation and enables a whole suite of RF applications relevant for use in 5G. Taken together, these key factors contribute to a meaningful advance of the semiconductor industry. Starting now, the advantages made possible by AMP are leveraged by a large OEM manufacturer of integrated circuits in one of its production sites in South-East Asia. Together with LPKF, the company recently installed an LPKF system, which will make the AMP process available for high volume manufacturing in advanced packaging applications.
More than ever, innovative solutions for mounting and connection technology are crucial factors in the semiconductor industry. Functional integration of the kind made possible by AMP technology is another signifi-cant step towards this goal. Active Mold Packaging simplifies integrated circuits (ICs) and systems-in-package (SiPs), and it increases value add for the users. When using AMP, the epoxy molding compound (EMC) – previously used only to protect ICs or SiPs – is converted into an active carrier of electrical functionality. The simple, time-saving, and reliable 2.5D packaging approach of AMP is based on three proven and standardized electronic production technologies: EMC encapsulation, laser processing using laser direct structuring (LDS), and selective metallization of the laser-processed areas with copper.
A new class of epoxy molding compounds (EMCs) has been developed for the laser direct structuring (LDS) process and is available in granulate and tablet form from a selection of well-known suppliers. In addition, this material is well suited for the plating process. In this process, laser direct structuring can reach a resolution range of 25µm for each linewidth and space.
Active Mold Packaging enables direct, electrically conducting connections between active and passive components in an IC or SiP. This shortens electrical path lengths and thus ohmic resistance and induct-ance.
Target applications of AMP are currently being developed for the 5G technology segment, and also for “beyond 5G” (B5G) – or 6G – RF technologies. They can apply to a wide range of uses: mmWave antennae as antenna-in/on-package (AiP/AoP) modules that operate in ISM bands at e.g. 24 GHz, 61 GHz, and 121 GHz, vehicle radar modules that operate between 76 GHz and 81 GHz, 5G amplifiers, or even EMI shielding. Other applications are package-on-package (PoP), 2L interposers, multi-chip modules (MCMs), thermal management and SiP connections.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week
07/18/2025 | Nolan Johnson, I-Connect007It may be the middle of the summer, but the news doesn’t quit, and there’s plenty to talk about this week, whether you’re talking technical or on a global scale. When I have to choose six items instead of my regular five, you know it’s good. I start by highlighting my interview with Martyn Gaudion on his latest book, share some concerning tariff news, follow that up with some promising (and not-so-promising) investments, and feature a paper from last January’s inaugural Pan-European Design Conference.

Digital Twin Concept in Copper Electroplating Process Performance
07/11/2025 | Aga Franczak, Robrecht Belis, Elsyca N.V.PCB manufacturing involves transforming a design into a physical board while meeting specific requirements. Understanding these design specifications is crucial, as they directly impact the PCB's fabrication process, performance, and yield rate. One key design specification is copper thieving—the addition of “dummy” pads across the surface that are plated along with the features designed on the outer layers. The purpose of the process is to provide a uniform distribution of copper across the outer layers to make the plating current density and plating in the holes more uniform.
