DuPont expands CooLam LED heat sink capacity in Taiwan

Recently, DuPont Precision Circuits and Packaging Materials announced that it has expanded the supply capacity of DuPont CooLam heat sink substrates by more than seven times. CooLam products were first produced at the Towanda plant in Pennsylvania, and in order to meet the needs of rapid growth, the capacity has been expanded to produce in Hsinchu, Taiwan.

In order to achieve a long and efficient service life, a stable and reliable heat sink substrate is an indispensable material for manufacturing LED bulbs. The DuPont CooLam heatsink substrate contains a patented polyimide dielectric designed for thermal conductivity and provides faster and more reliable heat dissipation than traditional epoxy-based boards. Due to its ultra-low thermal impedance and operating temperatures up to 180 °C, the CooLam heatsink substrate remains stable under a variety of environmental conditions.

DuPont offers three CooLam product types to meet the current industry demand for thermal applications. The latest CooLam3D heatsink substrate is designed for the innovative omnidirectional A-19 replaceable bulb and the direct light source required for general illumination; CooLamLX is designed for interchangeable LED bulbs and other ultra-low thermal impedances Lighting applications such as highbaylighting and outdoor lighting are designed; CooLamLA is designed for LED lighting applications that require more stringent electrical performance.

ETH Miner

Mining is the process of creating a block of transactions to be added to the Ethereum blockchain in Ethereum's now-deprecated proof-of-work architecture.

The word mining originates in the context of the gold analogy for cryptocurrencies. Gold or precious metals are scarce, so are digital tokens, and the only way to increase the total volume in a proof-of-work system is through mining. In proof-of-work Ethereum, the only mode of issuance was via mining. Unlike gold or precious metals however, Ethereum mining was also the way to secure the network by creating, verifying, publishing and propagating blocks in the blockchain.

Mining ether = Securing the Network

Mining is the lifeblood of any proof-of-work blockchain. Ethereum miners - computers running software - used their time and computation power to process transactions and produce blocks prior to the transition to proof-of-stake.
