Product Description

Gold finger PCB 2 Layer cricuit board with Black Soldermask and Immersion Gold


Commodity Introduction
This is a type of FR-4 PCB for the application of CODEC. It's a 2  layer board at 1.6mm thick.
The base laminate is from ITEQ, Solder mask and silkscreen from Kuang Shun and Taiyo. It's
fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 10 boards or panels are pa
-cked separately.

Layer Stackup

The purpose of stackup is to interleave the thin laminates and the prepreg sheets in correct
sequence and ensure correct layer-to-layer registration. The stackup of multilayer boards can be
done in many different ways.

Among multilayer PCB's, 12- layer is the largest number of layers that can be produced easily in
1.6mm thick.
