Multi-layer Printed Circuit Board 8 Layer PCB Board Built on Tg170
FR-4 With Immersion Gold for Wireless Communication.
1.1 General description
This is a type of 8 layer printed circuit board built on FR-4 Tg170
substrate for the application of Wireless Communication. It's 1.6
mm thick with white silkscreen on green solder mask and immersion
gold on pads. The base material is from ITEQ supply 1 up board per
panel. They're fabricated per IPC 6012 Class 2 using supplied
Gerber data. Each 20 panels are packed for shipment.
