Enhancing functionality, accelerating time to market, and ensuring silicon yield resilience are all possible with heterogeneous and homogeneous integration
A new strategy for design and verification at all levels is necessary for today’s advance packages, which use manufacturing methods, materials, and procedures that resemble silicon foundry procedures more and more.
Accurately aggregating discrete devices and substrates—which can be active or passive—is one of the first difficulties a design team faces. These substrates and devices are available in a variety of formats and likely come from many manufacturers and sources.
Here are some of the tips for next generation IC Packaging Design Services:
More compact footprints
By removing some of the external components, an IC package is currently anticipated to free up board space, contribute to the development of a more robust design, and lower the cost of PCB assembly.
To maximize the space and provide design flexibility, the new packaging designs also offer interchangeable pinout options. Additionally, some packages have inline or zigzag leads, which optimizes the board space and necessary pin spacing.
Some of the new packages for battery-powered designs are also being create with a threshold voltage at the logic level, enabling them to be driven directly from the microcontroller by power devices.
Power output
The requirement for higher power density without increasing packaging size is being driven by the rising demand for power chips and modules in devices including motor drives, solar inverters, and power supply.
How can designers boost power density while maintaining the reliability and durability of the package? First off, a package can support bigger power processors like insulated-gate bipolar transistors by having a larger lead frame area (IGBTs). Additionally, the package’s thermal resistance is reduce as a result, allowing for better heat dissipation.
Power switches are safeguard by the shutdown circuitry, and low voltage malfunction is avoid using undervoltage lockout. The bootstrap diode does the same thing by lowering the bill of materials (BOM) and streamlining board architecture.
It demonstrates how selecting the right package is essential to increase energy efficiency and take into account a wide supply range. It’s also important to note that advancements in thermal conditions are link to a package’s power density in this context.
Heating effectiveness
The reliability of a package is inextricably link to its thermal behavior some operate more efficiently at lower temperatures. The size of the heatsink is also influence by thermal properties. Because smaller heatsinks can withstand lower temperatures. Additionally, less cooling is need, giving designers more room to enhance power density.
There are packages that expose the top-side source electrode as a location for heat dissipation. While retaining the footprint and thermally efficient bottom-side architecture of the package. As a result, the current rating is increase, increasing power density and decreasing package footprints.
Changing losses
In particular, in hard-switching circuits working up to 20 kHz in devices like industrial drives. It is crucial to reduce switching losses to increase package efficiency. Further enhancing heatsink-free operating in low-power applications are dependable switching and reduced EMI.
A second Kelvin emitter source pin is include in some packaging designs to reduce switching losses. The gate control loop’s emitter lead inductance is bypassed, increasing a component’s switching speed and decreasing switching energy.
By eliminating the requirement for isolation materials and thermal grease. Such isolation packages enable designers to save the assembly time by up to 35%. It also increases reliability by getting rid of mismatched foils. Additionally, it results in advancements like 10°C lower temperature than a FullPAK.
Virtual prototype’s digital twin
Building a virtual twin of the 2.5D/3D heterogeneous assembly gives a thorough depiction of the entire system. Which includes several devices and substrates.
Enhancing device functionality, accelerating time to market, and ensuring silicon yield resilience are all possible with heterogeneous and homogeneous integration.
The ability to drive thorough physical and electrical verification. At every level of the design hierarchy is one of the key advantages of the digital twin approach. As a result, a complete, system-level netlist in Verilog format takes the place of various, static spreadsheets. That were previously use to record pin and connectivity information.
Integration of multiple domains
Multi-domain and cross-domain integration is also make possible by a digital twin methodology. It is necessary to design and verify complicated sophisticated IC packages with high integration. Including electrical, thermal, test, reliability, and, of course, manufacturability. From the design of the electronic substrate to the mechanical package heat spreader. Engineers run the danger of expensive respins or worse without a system-level approach to design and verification.
Unique Projects
The ability to synchronize package design with mechanical and thermal design is another major obstacle to first-time success for pc board manufacturers. One of the most significant chip-package interactions in heterogeneous multi-substrate packages is the thermal dissipation of heat. Particularly the non-linearly generated heat that is typical of such packages.
A heat spreader is typically use for heat transfer and heat dissipation in thermal management strategies. A heat spreader, however, is only as effective as its design. The heat spreader must be develop and simulated in conjunction with the package. Not as an afterthought, for it to be efficient and successful. The entire package being design in 3D ensures effective heat transfer without making substantial design sacrifices.
Flexibility and scope
Because heterogeneous packaging methods are more difficult to develop, make, and assemble, only the top semiconductor businesses with cutting-edge products may be able to use them.
Design guidelines that the foundry develops and makes available to design houses in a PDK serve as the foundation for automated IC verification. To ensure that their verification tools generate results. That are proven, reproducible, and signoff-quality, EDA tool suppliers evaluate their toolsets against these guidelines.
Advanced IC packages’ size and complexity placed direct pressure on designers and their often-extended design schedules. Concurrent team design is a growingly popular method of handling this. Allowing multiple designers to work on the same design simultaneously over local or international networks. While maintaining the ability to visualize all design activity without having to deal with cumbersome setup or process management.
