Cutting, fillet, edging, baking, inner layer pretreatment, coating, exposure, DES (development, etching, film removal), punching, AOI inspection, VRS repair, browning, lamination, pressing, target drilling, Gong edge, drilling, copper plating, film pressing, printing, writing, surface treatment, final inspection, packaging and other processes are countless
People who make circuit boards know that the production process is very complex~
the difference between longitude and latitude causes the change of substrate size; Due to the failure to pay attention to the fiber direction during shearing, the shear stress remains in the substrate.
The development of printed circuit board substrate materials has gone through nearly 50 years
Integrated circuit is a way of miniaturization of circuits (mainly including semiconductor equipment, also including passive components, etc.). Using a certain process, the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit are interconnected, fabricated on a small or several small semiconductor chips or dielectric substrates,
Under the background of chip shortage, chip is becoming a crucial field in the world. In the chip industry, Samsung and Intel have always been the world's largest IDM giants (integrating design, manufacturing and sealing and testing, basically without relying on others). For a long time, the Iron Throne of global chips was fought back and forth between the two until TSMC rose and the bipolar pattern was completely broken.
