What Are The 6 Key Steps in Chip Manufacturing?
In 2020, more than a trillion chips were produced worldwide, which equates to 130 chips owned and used by each person on the planet. Yet even so, the recent chip shortage continues to show that this number has not yet reached its upper limit. Although chips can already be produced on such a large...Read more -
What Is HDI Circuit Board?
I. What is HDI board? HDI board (High Density Interconnector), that is, high-density interconnect board, is the use of micro-blind buried hole technology, a circuit board with a relatively high density of line distribution. HDI board has an inner line and outer line, and then the use of drilling,...Read more -

Why SMT needs a reflow oven tray with a full carrier?
SMT reflow oven is an essential soldering equipment in the SMT process, which is actually a combination of a baking oven. Its main function is to let the paste solder in the reflow oven, the solder will be melted at high temperatures after the solder can make the SMD components and circuit boards...Read more -
How to Optimize PCB Design?
1. Figure out which are the programmable devices on the board. The devices on the board are not all programmable within the system. For example, parallel devices are usually not allowed to do so. For programmable devices, the serial programming capability of the ISP is essential to maintain desig...Read more -
