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
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

Backplane,
High performance computing
Line
cards, Storage
Servers,
Telecom, Base station, Office Routers
