A Nikkei report spells bad news for anyone hoping that prices of electronic devices won’t go up this year. A critical component in many products with advanced chips in them is in short supply.The material is called “glass cloth” and it is an important component in a particular type of substrate (essentially a little pad that the chip is mounted on to attach it to the circuit board). There aren’t may companies that make it at a high quality level and high volume.
