Fan-Out Packaging Gets Competitive


Fan-out wafer-level packaging (FOWLP) is a key enabler in the industry shift from transistor scaling to system scaling and integration. The design fans out the chip interconnects through a redistribution layer instead of a substrate. Compared to flip-chip ball grid array (FCBGA) or wire bonds, it creates lower thermal resistance, a slimmer package, and potentially lower costs. Yet, if the h... » read more

Scaling Bump Pitches In Advanced Packaging


Interconnects for advanced packaging are at a crossroads as an assortment of new package types are pushing further into the mainstream, with some vendors opting to extend the traditional bump approaches while others roll out new ones to replace them. The goal in all cases is to ensure signal integrity between components in IC packages as the volume of data being processed increases. But as d... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs Samsung has announced its latest foldable smartphones--the Galaxy Z Fold3 5G and Galaxy Z Flip3 5G. The systems are based on Samsung’s 5nm application processor. One system is the company’s most affordable foldable phone. The Galaxy Z Fold3 is $1,799.99, while the Galaxy Z Flip3 is $999.99. Samsung also announced two smartwatches—the Galaxy Watch4 and Galaxy Watch4... » read more

Shortages, Challenges Engulf Packaging Supply Chain


A surge in demand for chips is impacting the IC packaging supply chain, causing shortages of select manufacturing capacity, various package types, key components, and equipment. Spot shortages in packaging surfaced in late 2020 and have since spread to other sectors. There are now a variety of choke points in the supply chain. Wirebond and flip-chip capacity will remain tight throughout 2021... » read more

Planning For Panel-Level Fan-out


Several companies are developing or ramping up panel-level fan-out packaging as a way to reduce the cost of advanced packaging. Wafer-level fan-out is one of several advanced packaging types where a package can incorporate dies, MEMS and passives in an IC package. This approach has been in production for years, and is produced in a round wafer format in 200mm or 300mm wafer sizes. Fan-out... » read more

Manufacturing Bits: June 4


Chiplet printer A number of companies, R&D organizations and universities separately presented a slew of papers and technologies at the recent IEEE Electronic Components and Technology Conference (ECTC) in Las Vegas. It’s difficult to write about all of the papers at ECTC. But one paper that stood out is a prototype chiplet micro-assembly printer developed by the Palo Alto Research Cente... » read more

Panel Fan-out Ramps, Challenges Remain


After years of R&D, panel-level fan-out packaging is finally beginning to ramp up in the market, at least in limited volumes for a few vendors. However, panel-level fan-out, which is an advanced form of today’s fan-out packaging, still faces several technical and cost challenges to bring this technology into the mainstream or high-volume manufacturing. Moreover, several companies are d... » read more
