At today's data rates, the package is no longer electrically invisible. A SerDes lane running tens of gigabits per second, a DDR interface tightening its timing margins, or a 5G/6G mmWave antenna radiating above 100 GHz will all expose package parasitics that a slower design would never have noticed. The interconnect that used to be a wire is now a transmission line with impedance, crosstalk, and loss that decide whether the link closes. ASE's Electrical Laboratory (E-Lab) is built to characterize and design out exactly those effects — across simulation and measurement, from DC power delivery up to 260 GHz.
The E-Lab works with customers on IC package electrical design, analysis, and characterization: package design optimization, system-level signal-integrity and power-integrity (SI/PI) analysis, high-speed and high-frequency performance verification, and turnkey passive filter solutions. It also provides advanced, high-accuracy measurement for package characterization, electrical failure analysis, and both chip- and system-level millimeter-wave (mmWave) antenna-in-package (AiP).
Designing the Electrical Behavior In
Electrical performance is decided at design time, so the E-Lab's design service starts where the problems originate. It covers impedance control, package design optimization for the demanding interfaces — DDR, SerDes, and power — and RF filter design and characterization. For mmWave and high-density modules, it also covers package EMI shielding design, in both conformal and compartment forms, so a noisy radio and a sensitive receiver can share a package without interfering.
Those design choices only transfer to the customer's flow if they arrive as usable models. The E-Lab's modeling service delivers package R/L/C models and S-parameter models, and exports them in the formats system designers actually run — package IBIS, SPICE, and S-parameter models — so the package can be co-simulated inside the larger system rather than treated as a black box.
Signal Integrity and Power Integrity
SI and PI are the two halves of "does the link work and does the silicon get clean power," and the E-Lab addresses both.
On signal integrity, the lab runs TDR simulation, eye-diagram analysis, and crosstalk, jitter, and timing analysis — the toolset that tells a designer whether a high-speed lane will close its eye at the target data rate or whether the package routing needs rework first. On power integrity, it covers DC IR-drop, power distribution network (PDN) analysis, decoupling-capacitor (de-cap) optimization, and power-noise analysis — the work that keeps supply rails quiet enough for high-current AI, HPC, and processor silicon to hit their performance without throttling on noise.
Measurement Up to 260 GHz
A model is only as good as the measurement that anchors it, and the E-Lab's measurement capability reaches the frequencies modern designs actually operate at. Its S-parameter characterization spans an unusually wide range:
| Capability | Specification |
|---|---|
| Double-side S-parameter probe station | Up to 170 GHz |
| Single-side S-parameter probe station | Up to 260 GHz |
| Wafer / panel-level S-parameter probe station | 12-inch wafer and panel size |
Alongside S-parameters, the lab performs electrical failure analysis using TDR impedance and 4-wire DC resistance (open/short) techniques, and characterizes parasitics at the component level, including on-chip capacitors and RF inductors. Reaching 260 GHz on a single-side probe and supporting full 12-inch wafer- and panel-level S-parameter measurement is what lets the E-Lab characterize the next generation of mmWave and high-speed packages rather than just today's.
Antenna-in-Package Testing: Chip Level to System Level
mmWave AiP is where electrical characterization meets antenna performance, and the E-Lab supports it at two levels with two dedicated chambers.
The spherical chamber handles chip- and package-level passive testing through a probing feed, measuring antenna gain and 2D radiation pattern over 18 to 110 GHz with spherical and direct far-field capability. The Compact Antenna Test Range (CATR) chamber moves up to system-level active testing through a connector feed, with a 30 × 30 cm² quiet zone over the same 18-110 GHz range, measuring antenna gain, equivalent isotropically radiated power (EIRP), and full 3D pattern — and, critically, beamforming test. Beamforming verification at the system level is exactly what a 5G/6G phased-array module needs before it can be qualified, which is why pairing both chambers under one roof matters for antenna-in-package programs.
Where the E-Lab Fits in ASE's Portfolio
ASE is the world's largest outsourced semiconductor assembly and test (OSAT) provider, and the Electrical Laboratory is one pillar of the analytical backbone behind its packaging — working alongside the Stress-Thermal Laboratory on the mechanical and thermal side and the broader test services organization. As designs push into heterogeneous integration (HI), chiplet interconnect, and mmWave AiP, the package's electrical behavior becomes a first-order design variable — and having SI/PI simulation, up-to-260-GHz measurement, and AiP antenna testing co-located with assembly lets a customer treat electrical performance as a design input from the first day, not a problem discovered at bring-up.
What Comes Next
As SerDes rates climb, DDR generations tighten, and 5G/6G push radiated frequencies higher, the package's contribution to the electrical budget keeps growing. ASE's Electrical Laboratory — spanning impedance and EMI design, IBIS/SPICE/S-parameter modeling, full SI/PI analysis, S-parameter measurement to 260 GHz, and chip- to system-level AiP testing with beamforming — gives product teams a way to verify and optimize electrical performance before silicon, backed by a partner that carries the discipline from mature packages through heterogeneous integration and mmWave AiP.

Frequently Asked Questions
Q: What does ASE's Electrical Laboratory (E-Lab) do? A: The E-Lab provides IC package electrical design, analysis, and characterization through simulation and measurement. It covers package design optimization, system-level signal-integrity and power-integrity (SI/PI) analysis, high-speed and high-frequency verification, turnkey passive filter solutions, package characterization, electrical failure analysis, and chip- and system-level millimeter-wave (mmWave) antenna-in-package (AiP) testing.
Q: What is the difference between signal integrity and power integrity analysis? A: Signal integrity (SI) confirms that a high-speed link works: the E-Lab runs TDR simulation, eye-diagram analysis, and crosstalk, jitter, and timing analysis. Power integrity (PI) confirms the silicon gets clean power: the lab covers DC IR-drop, power distribution network (PDN) analysis, decoupling-capacitor optimization, and power-noise analysis. Both are needed for high-speed AI, HPC, and processor designs.
Q: What frequency range can ASE's E-Lab measure? A: The E-Lab's S-parameter characterization reaches up to 170 GHz on a double-side probe station and up to 260 GHz on a single-side probe station, with 12-inch wafer- and panel-level capability. Its mmWave AiP chambers operate over 18 to 110 GHz. This range covers high-speed SerDes, DDR, and 5G/6G mmWave designs.
Q: How does the E-Lab test antenna-in-package (AiP) modules? A: The E-Lab uses two chambers. A spherical chamber performs chip- and package-level passive testing via a probing feed, measuring antenna gain and 2D pattern over 18-110 GHz. A Compact Antenna Test Range (CATR) chamber performs system-level active testing via a connector feed, with a 30 × 30 cm² quiet zone over 18-110 GHz, measuring antenna gain, EIRP, full 3D pattern, and beamforming.
Q: What package models can the E-Lab provide? A: The E-Lab generates package R/L/C models and S-parameter models, and exports them as package IBIS, SPICE, and S-parameter models. These let system designers co-simulate the package inside the full system rather than treating it as a black box, which is essential for closing high-speed and high-frequency timing and power budgets.
