The coronavirus pandemic has led to tighter supply and higher prices for some components including multilayer ceramic capacitors.
Shutdowns and slowdowns in production of electronic components and other manufacturing materials in China caused by the outbreak of coronavirus has resulted in longer lead times, shortages and price increases for some electronic components.
Industry analysts, distributors and buyers say they expect coronavirus will likely continue to disrupt the electronics supply chain through the first half of the year and perhaps longer, resulting in slower component and end equipment shipments and lower sales revenue for semiconductor and other component companies in 2020.
Coronavirus began in Wuhan, Hubei province in China and its impact started to be felt in January when many companies had shut down production for two weeks because of Chinese New Year. Many factories remained shut down for two or more weeks after the lunar new year because of the spread of the virus. When factories reopened in February many operated at 30 to 60 per cent capacity.
As a result, buyers at OEMs and EMS providers expect shipment delays of components and other materials needed for production. A survey conducted by trade association IPC said electronics manufacturers are expecting at least a five-week delay in components and other production materials. IPC surveyed OEMs, electronics manufacturing services providers and printed circuit board manufacturers.
About 65 per cent of manufacturers surveyed said they were told by their suppliers to expect a three-week delay in deliveries of components and materials. However, executives at electronics manufacturers surveyed said they expect delays to be longer than what their suppliers were saying. On average, manufacturers were expecting shipment delays of at least five weeks and some said delays could be nine weeks or longer.
“The delays will likely have ripple effects for the rest of the year,” said John Mitchell, IPC’s president and CEO. “The longer China is affected by the epidemic, and the more it spreads to other parts of the world, the supply chain will experience more and varied strains and disruptions.”
The survey found that 84 per cent of electronics manufacturers and suppliers are worried about the coronavirus’ impact on their business operations including factory downtime, higher costs, transportation bottlenecks, pressure for alternative sourcing, delayed sales, and delayed prototyping that slows the introduction of new products.
Some companies said that they were considering alternate sources for parts materials produced in China. However, in most cases “it’s not easy for manufacturers to switch suppliers,” said Mitchell. “Securing alternate sources requires an investment of significant time and money that must be weighed against the value gained.”
MLCC shortages again?
One company that has already seen delays in shipments of components is EMS provider Vexos. Lead times of “raw boards and mechanicals are extended at least four weeks and some longer,” said Stephanie Martin, senior vice president global supply for Vexos, which has manufacturing facilities in the US, Canada, Denmark, China and Vietnam.
There are also delivery delays, shortages and price increases for electronic components. “Hardest hit seems to be the passive products particularly MLCCs. Some suppliers are not even acknowledging new orders. So, we have shortages, price increases and extended lead-times all happening,” she said in early March.
Vexos is telling its buyers if there is available inventory of components, but the parts are not needed until May or June, buyers should “pull in the delivery date of the order and take the stock in house,” said Martin. “Right now (in early March) there is availability of stock in the channel in many cases. The delay caused by the coronavirus and subsequent freight issues will create a hole in the available inventory down the road,” she said. Vexos wants to make sure it has parts in inventory that it may need in the future so production is not impacted, said Martin.
Besides passive components and printed circuit boards, buyers may also find it’s harder to buy light emitting diodes (LEDs) and liquid crystal displays (LCDs) because of production slowdowns by suppliers in China. China’s display utilization rate fell about
20 to 25 per cent in February and the country’s overall production output would drop 40 to 50 per cent due to component shortages, according to research firm Omdia.
There are about 20 LED and LCDs buyers in the coronavirus affected areas of China. Many suppliers have resumed operations, but many employees did not return to work when factories reopened in February, so unit production of LEDs and LCDs in the first quarter declined. Compared to the first quarter of 2019, the researcher said. LCD panel makers also face challenges sourcing components needed for production, including LCD polarizers, LCD modules printed circuit boards and other ICs because of a slowdown in customs clearance, according
Delays and shortages seen
While coronavirus has slowed down production of many components and materials, industry analysts said in early March that it was too early to say how severe the impact will be on the electronics supply chain, but said it will have a negative impact on sales for 2020.
“The biggest impact initially has been some delays in shipping products,” said Paul Romano, chief operating officer of independent distributor Fusion Worldwide, based in Boston. He noted that some suppliers in China had been “shuttered for the last 30 to 45 days and that is going to create some impact with our market.”
“We’re seeing shortages across a number of different products,” but the coronavirus is not the only reason for tighter availability of some parts, according to Romano. “Certainly, there is still some hangover from what we saw in 2018 and 2019,” when there were severe shortages of MLCCs, chip resistors and some discretes. At the same time there has been a push in usage and demand is outstripping supply,” said Romano.
“Many of those parts are produced in China and Japan. Remember China also produces many of the raw materials” needed for production of components which is contributing to the slowdown in manufacturing of parts, he said.
Because component manufacturing in China shut down for a while some component manufacturers “are trying to moderate demand and shortages by not accepting new orders. We expect that practice will continue to grow,” said Romano.
Little impact on chips
The good news for semiconductor buyers is that coronavirus has had little impact on semiconductor production in China. “Global chip supply through the first two months of 2020 appears to be largely unaffected by the coronavirus outbreak,” said Len Jelinek, research vice president, components & devices, for researcher Omdia.
“There’s plenty of chip inventory in the channel, compensating for any coronavirus-related production shortfalls at semiconductor fabs located in the Wuhan area and elsewhere in China are a few semiconductor suppliers located in areas affected by the virus,” said Jelinek.
The bad news is semiconductor packaging and testing operations were being adversely impacted by coronavirus because employees could not make it back to work following Chinese new year because of travel restrictions caused by the virus. As a result, many chip packaging and testing plants in China reduced or stopped operations, which created a bottleneck for chip companies that rely on back-end packaging and testing capacity, according to Omdia.
Perhaps the biggest problem for chipmakers is that coronavirus is disrupting production at electronics manufacturing services (EMS) providers and original design manufacturers (ODM). Those companies are the world’s largest semiconductor buyers accounting for about 29 per cent of global chip purchases, said Jelinek. EMS providers and original design manufacturing (ODM) companies also face worker challenges as many electronics manufacturing employees were not able to return to work because of coronavirus.
Major EMS/ODM operations in China include Foxconn’s iPhone production operations located about 300 miles from Wuhan in Zhengzhou. This plant was open and running, but only at about 10 to 20 percent of capacity due to workforce issues in February, according to Omdia. Jabil Circuit said the outbreak has slowed its electronics factories in the affected part of China to 65 to 70 percent of normal output.
EMS provider Plexus has facilities in China and its business has slowed because of the effect coronavirus has had on its supply base according to Omdia. It expects a $40 million drop in its fiscal second quarter revenues.
The capacity utilization rate for all electronics manufacturers in China was lower than normal in late February, the researcher said. Reduction in the production of equipment means fewer semiconductors and other components need to be purchased.
Semiconductor suppliers in China are also dealing with the logistics issues because of restrictions on air travel to and from China. The restrictions prevented many government staff numbers from returning to work after the lunar new year holiday break. As a result, the import/export process in China now is taking much longer than before, slowing the pace of commerce, said Omdia.
Electronics production resuming
Kevin Anderson, senior analyst, power semiconductors for Omdia, said there had been improvement in China in early March in terms of production resuming for components and other materials used in electronics. “But we are not out of the woods yet,” he said. Coronavirus will have a big impact in first-quarter sales for many semiconductor companies. In addition the slowdown in production materials needed by electronics OEMs will continue beyond the first quarter.
“We think there will be some impact on Q2 as well. It depends on how quickly all the factories can get workers back in place,” said Anderson. He said that coronavirus will result in semiconductor sales revenue planning by about 3 per cent this year.
However, Anderson said a silver lining in terms of disruption of production caused by coronavirus is that the outbreak occurred during the Chinese New Year. “A lot of the companies had built ahead in anticipation of the lunar new year so there was inventory. If the outbreak had happened in Q3 we would have a lot different situation because there would have been a lot more demand and less inventory in the supply chain, he said.
Electronics distributors are not sure how much the outbreak will impact their businesses for the year, but in the short term it may boost sales as buyers at OEMs and EMS providers build their own inventories because of fear of shortages and price increases later in the year.
“Right now things are a little bit cloudy. There is some thought that with the coronavirus situation anyone who has inventory is likely going to be in a good position,” said Jeff Newell, senior vice president of products for Mouser Electronics. “That’s generally true, but then again once
you sell through it, replenishing inventory might be a bit difficult.”
Don Akery, president, TTI Americas, said TTI was starting to see increased booking activity driven by fear of supply chain disruptions, including “customers placing orders further out. We are moving to ensure that our customers have assurance of supply and peace of mind,” he said.
“We are seeing some uptick in sales. When people fear a disruption of their supply chain, the scarcity mentality comes in and people want to secure some products to be safe,” said Dave Doherty, president and chief operating officer for Digi-Key “ We’re seeing some of that,” he said in March.
He said the full extent of the disruption of production component factors was not known as of early March. “We don’t have a handle on how big the disruption of the supply chain is going to be.”
Distributors are trying to get as much information as possible from their component manufacturers that they carry. “We are in constant conversations with our suppliers about deliveries and expectations of when products will be available when they will be delivered,” said Frank Cantwell, vice president of product and supplier management Allied Electronics.
