  HDI is the abbreviation of High Density Interconnection, which is a kind of technology for the production of printed circuit boards.   High density interconnection PCB   board is a circuit board with a relatively high line distribution density using micro-blind and buried via technology. HDI includes the use of fine features or signal traces and spaces of 0.003” (75 µm) or less and laser-drilled blind or buried microvia technology. Microvias allow the use of micro-interconnects from one layer to another within a PCB utilizing a smaller pad diameter creating additional routing density or reducing form factor. HDI pcb board is a compact product designed for small-capacity users. Advantages of high-density interconnected PCB boards It can reduce the cost of PCB: When the density of PCB increases to more than eight-layer board, it is manufactured by HDI, and its cost will be lower than that of the traditional complex pressing process. Increase circuit density: has better in...

  Advantages of aluminum PCB printed circuit boards It is more suitable for SMT process; Meet the requirements of RoHs; The heat dissipation has been effectively treated, thereby reducing the operating temperature of the module, prolonging the service life and improving the reliability; The volume is decreasing, reducing the assembly area of ​​radiators and other hardware, reducing product volume, and reducing hardware and assembly costs; Good mechanical durability, better than ceramic circuit boards made by some simple processes. Disadvantages of aluminum pcb printed circuit boards Higher cost: Compared with other cheap PCB products, the price of aluminum-based PCB boards accounts for 30% of the total product price. At present, the mainstream manufacturer can only make single-sided PCB boards, and it is difficult to make double-sided aluminum PCB boards. At present, single-sided aluminum PCB boards are relatively skilled in China, and the process and technology of multi-layer alum...

  Main usages and applications of aluminium PCB board: Audio devices: input, output amplifiers, balanced amplifiers, audio amplifier, preamplifier, power amplifier etc. Power Supply: switching regulator, DC / AC converter, SW regulator . Telecommunications electronic equipment: high-frequency electric amplifiers, filtering appliance, transmitter circuit etc . Office automation equipment: electric motor, drivers etc .

Aluminum pcb vs fr4 pcb board FR4 board is a code name for the grade of flame-retardant material. It represents a material specification that the resin material must be able to extinguish by itself after burning. It is not a material name, but a material grade. ...
