How to define the order of HDI board | YMSPCB
HDI PCB: non-mechanical drilling, microblind hole ring less than 6mil, inner and outer layer wiring line width. When the gap is less than 4mil and the diameter of the welding pad is no more than 0.35mm, the multilayer production method is called HDI board. 2 Step HDI Bo...Read more -
HDI PCB market supply and demand analysis and circuit advantages | YMSPCB
HDI (High Density Interconnector) printed circuit board (PCB) is a structural component composed of insulation and conductor wiring. Printed circuit boards are assembled with integrated circuits, transistors (transistors, diodes), passive components (resistors, capacitor...Read more -
what are HDI boards | YMSPCB
HDI, short for high-density interconnection, is the production of printed circuit boards, which use microblind burrow technology, a circuit board with a relatively high circuit distribution density. HDI PCB is a compact product designed for small capacity customers. It i...Read more -
Soldered FPC gold finger design tips | YMSPCB
FPC, flexible circuit board. The number of FPC circuits can exceed 100, but only occupies a thickness of 0.2mm. Although more expensive than wiring, it is widely used in compact smart hardware. Especially mobile phones, smart watches and other scenarios. Soldered FPC gol...Read more -
