Let’s talk about COB packaging in detail. Why is it so important for LED chips?
ByGrace January 28, 2025January 21, 2025
What is COB? Its full name is chip-on-board, which is a new packaging method that is different from SMD surface mount packaging technology. Specifically, the LED bare chip is adhered to the PCB with conductive or non-conductive glue, and then wire bonding is performed to achieve its electrical connection, and the chip and bonding wires…

Four Steps to Ensure Successful PCB Design
ByGrace January 28, 2025January 21, 2025
Printed circuit boards (PCBs) are the backbone of electronic products, and the performance, life, and reliability of the end product depend on the electrical systems they form. If designed properly, products with high-quality circuits will have lower field failure and field return rates. As a result, products will be less expensive to produce and more…

Are FPGAs the new PCBs?
ByGrace January 27, 2025January 21, 2025
Perhaps the biggest change in the industry in recent years has been the introduction of low-cost microprocessors. Microprocessors were first used to implement calculators and then personal computers. With their dynamic reconfiguration capabilities, they have replaced many hard-wired digital system circuits, bringing true “embedded artificial intelligence” to previously “dumb” devices. The key to the success…
