Optimizing Your SoC or ASIC to Design PCBs More Cost Effectively

Optimizing Your SoC or ASIC to Design PCBs More Cost Effectively

Shrinking silicon process nodes and increasing memory demands are a nightmare for PCB design teams working with custom ASICs or SoCs on high-performance systems. Huge devices with challenging bump and package-ball net assignments must be integrated onto the PCB while overall system integrity is maintained and signal-layer count and overall PCB size stay within system and cost constraints. This pap... »

Implementing High-Density Advanced Packaging for OSATs and Foundries

Implementing High-Density Advanced Packaging for OSATs and Foundries

Moore’s law is increasingly difficult to maintain and is driving the growth of innovative, high-density advanced packaging technologies in response to system scaling demands. These innovations are increasingly in the form of fan-out wafer level packaging (FOWLP) or multi-substrate / multi-device packages like interposers and system-in-package (SiP). New challenges come with these disruptive tech... »

Replacing NMP: Are You Ready?

Replacing NMP: Are You Ready?

NMP is an abbreviation for N-methyl-2-pyrrolidone (other synonyms are 1-Methyl-2-pyrrolidone and 1-Methyl-2-pyrrolidinone) (Figure 1). NMP has proven itself as an effective and versatile cleaning agent, removing photoresist residue while leaving the surface in good shape for processing steps downstream. However, its time may be short-lived as companies strive to meet environmental health and safet... »

Designing and Integrating MCM/SIP Packages into Systems PCBs

Designing and Integrating MCM/SIP Packages into Systems PCBs

The challenge of designing smaller, cost-effective systems that require additional processing and performance power led to 3D chip stacking of bare die and a new approach to packaging known as SiP (systems-in-package), also known as multi-chip modules (MCMs). The benefits of MCM/SiP package technology include the ability to achieve greater functionality in a reduced time-to-market window that cann... »

Using Co-Design to Ensure Multi-Fabric System-Design Success

Using Co-Design to Ensure Multi-Fabric System-Design Success

As next-generation High-Density-Advanced-Packaging (HDAP) designs become more common, PCB designers and engineers are looking to system-level co-design to tie multi-substrate visualization, planning, and optimization, into a complete multi-board design. Co-design methodology allows design teams to plan and optimize I/O and connectivity from a chip, through multiple packaging scenarios, and on to p... »

Package Designers Need Assembly-level LVS Signoff for HDAP Verification

Package Designers Need Assembly-level LVS Signoff for HDAP Verification

While advanced IC packaging is a fast-growing market, comprehensive package verification still has a ways to go. Unique package connectivity issues, such as missing or misplaced interposer/package bumps/pads, pin naming and text labeling issues, and the like, require new and enhanced layout vs. schematic (LVS)-like verification techniques that can move across the entire package to ensure proper co... »

Perspectives on the Cost of Fan-out Wafer Level Packaging vs. Flip Chip Packaging

Perspectives on the Cost of Fan-out Wafer Level Packaging vs. Flip Chip Packaging

Recently, I read a paper published in the 2017 IMAPS Device Packaging Conference proceedings, titled “Cost Comparison of Fan-out Wafer Level Packaging and Flip Chip Packaging,” written by Amy Lujan, of Savansys. Lujan did a very good analysis on the cost comparison of fan-out wafer-level packaging (FOWLP)  with chip-first and die face-down and flip chip (FC) packaging, according to a... »

Striking the Right Chord for Chiplet Integration

Striking the Right Chord for Chiplet Integration

The growing digitalization of our society has made our lives connected and, in many aspects, easier. But the digital revolution also implies that the total amount of data processed in the world is doubling every two years or so. Electronic devices such as mobile phones, laptops, satellites, servers or self-driving vehicles must cope with twice as much data, at higher speeds. Traditional signaling ... »

Optimizing Your SoCs and ASICs to Design PCBs More Cost Effectively

Optimizing Your SoCs and ASICs to Design PCBs More Cost Effectively

Many high-performance systems today use custom ASICs or SoCs to provide the necessary computational power and data bandwidth demanded by their host system, whether it’s a network storage device, network data switch, complex industrial equipment controller, or a critical core module of a defense system. And they are not getting any smaller or slower as silicon process nodes shrink and memory dema... »
