In order to shorten the signal transmission distance and reduce the signal transmission loss, the 5G communication PCB, gradually move towards high-density wiring, fine wire spacing, the development of small aperture, thin profile and high reliability.   Process Difficulty Of High Frequency And High Speed PCB Board Alignment Accuracy Accuracy is tightened, and tolerance convergence between layers is required. The board size becomes more demanding for this convergence requirement Size Gets Bigger Machinability deteriorates, maneuverability deteriorates, and blind holes need to be buried 1. Cost increase 2. Difficulty in alignment accuracy Impedance Accuracy The etching challenge is great: 1. The etching factor: the smaller the better, the etching accuracy tolerance is 10mil and the line width is controlled by +/-1MIL, and the line width tolerance above 10mil is controlled by +/-10%. 2. Higher requirements for line width, line spacing and line thickness. 3. Others: wiring density, si...

Buried vias PCB & blind vias PCB, use micro blind vias to increase the trace distribution density. Improve radio frequency, electromagnetic wave interference and hear conduction. Apply to computer server, mobile phone and digital camera products.HUIHE CIRCUITS is China HDI PCB manufacturer, Our blind buried via PCB has passed ISO9001/ISO13485/IATF16949/UL/RoHS/REACH certification.   Are PCB Boards With Blind And Buried Vias Called HDI PCB?   HDI circuit boards  are high density interconnect PCB. The high density PCB that are plated with blind holes and then laminated are all HDI boards, which are divided into first-order, second-order, third-order, fourth-order, and fifth-order HDI. Simple buried vias are not necessarily HDI. .   The Difference Between hdi printed circuit boards   And Ordinary PCB   Through Hole Circuit Board Plating Through hole, or PTH for short, is the most common one. You only need to pick up the PCB and face the light, and the hole...
