TU-883 Multi-layer Printed Circuit Board (PCB) HDI Low Loss High Temperature PCB With 90 Ohm Impedance Controlled
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
Brief Introduction
This is a type of low loss high performance multi-layer PCB built on TUC’s TU-883 core with 20 copper layers (20-layer PCB). It’s also a type of HDI circuit boards (N+1+N) with 0.1mm laser drill. This is also a type of impedance controlled PCB, 90 Ohms and 50 Ohms are controlled on each signal layers with 10% tolerance. The copper foils are 1 oz and half oz used alternately between layers. The whole PCB is 3.0mm thick, with immersion gold on pads, green solder mask and white silkscreen.
Applications
Radio frequency
Backplane, High performance computing
Line cards, Storage
Servers, Telecom, Base station, Office Routers
