FC-BGA

Despite the pandemic lock-down, demand for electronic products and services remains strong. Work-from-home, video conferencing, and remote learning are driving data center growth and laptop and tablet demand. 5G infrastructure rollout is underway and smartphone sales are returning to normal levels. Automotive sales are increasing. At the same time, the industry is experiencing acute shortages of substrates. The October 2020 fire at Unimicron’s IC package substrate plant in Taiwan exposed the serious nature of the capacity shortage for IC package substrates. Substrate makers have been reluctant to make large investments in capacity over the last few years due to the fear that demand could decline and they would have excess capacity. Relentless price pressures by customers and the resulting low margins have weakened the finances of substrate suppliers. With tight capacity, substrate prices have increased and lead times are 14 weeks or more. The most critical shortage is for flip chip ball grid array (FC-BGA) substrates. In addition to increased demand in units, applications such as servers and networking products are seeing requirements for larger body sizes and increased layer counts. Shortages will not improve very soon because it takes time to build a new plant. And equip it. Key equipment for substrate production has lead times of up to a year. SEMI and TechSearch International detailed the substrate makers and provide projections for the substrate market, trends, and a list of suppliers and their plant locations in the Global Semiconductor Packaging Materials Outlook report. The report also highlights the market and suppliers for leadframes, bonding wire, encapsulation materials, underfill, die attach, solder balls, wafer level package dielectrics, and wafer-level plating chemicals. In times of shortages the report is an important indicator of suppliers in the industry and trends. Jan Vardaman is President at TechSearch International Inc.

Outsourced Semiconductor Assembly and Test (OSAT) service providers experienced strong growth in 2017, but will this growth continue? In the last few years, OSAT growth has been driven by shipments for packages found in smartphones, but this market is slowing. What will replace it? Growth in power devices is strong and electronic content in vehicles is increasing. Will OSATs participate in this growth? Many OSATs have plants dedicated to automotive package assembly and will see continued growth. Growing demand for connectivity everywhere, called IoT, is generating large amounts of data, creating the need for more servers and datacenters. The adoption of Artificial Intelligence (AI) across a broad range of applications is driving demand for high-performance packages, but will this assembly take place at the OSATs or foundries? In the third and fourth quarters of 2017, growth in cryptocurrency provided unanticipated revenue for a number of OSATs. Given that the most well-known crypto mining companies and the biggest mining pools are all based in China, several OSATs, including major Taiwanese and Chinese service providers, experienced revenue growth in 2017 directly attributed to the assembly of ASICs in flip chip scale packages (FC-CSPs) and GPUs in flip chip ball grid arrays (FC-BGAs) for the cryptocurrency market. However, the first and second quarter of this year has seen decreased demand for GPUs and ASICs for this application. The assembly of packages for cryptocurrency slowed considerably in the first half of the year and therefore can’t be counted on to add as much to the revenue base as in the previous year. Going into the latter half of the year, the demand for Crypto ASICs is expected to pick up as new generation of 7nm chips will drive new investment and replacement cycle while crypto-mining GPU will see a further decline. Three of the top 10 OSATs, Jiangsu Changjiang Electronics Technology (JCET), Tianshui Huatian Technology (Huatian), and Tongfu Microelectronics (TFME), are based in China. China’s share of the top 10 OSATs’ revenue increased from slightly less than 23 percent in 2016 to more than 25 percent in 2017, and this trend is expected to continue. Crypto-related packaging and test business has certainly contributed a big portion of the share gain. Major OSATs such as TFME and Tianshui Huatian plan expansion in their plants and they expect to fill this added capacity in a broad range of packages. Huatian’s new Nanjing plant will include assembly for memory packages. TFME plans to set up a plant in Xiamen, Fujian Province to provide bumping, wafer level packaging, and system-in-packaging (SiP) services. Tracking the capabilities of OSATs is increasingly important. SEMI and TechSearch International have introduced a new Worldwide OSAT Manufacturing Site Database that provides listings of OSAT facility locations and package and test options in each factory. This database indicates the specific packages offered at each location. Finding plants that offer automotive qualified assembly is also possible with the database. Companies that offer bumping and wafer level packaging are identified. Over 120 companies and 300 facilities are tracked in this database covering both OSAT packaging and test facilities.
