3  Manufacturing flow:

Main flow

FCCL Cutting->Drilling->electroplating->Brown Oxide->Inner circuit->Coverlay->Bonding->laminating ->Panel PTH->

outer circuit->pattern PTH->Etching>solder mask->Immersion gold->FPC UV lasering->E-TEST->Outline->FQC

 

4  Process difficulties:

a. This product adopts a flying tail structure, and the soft board needs to be selectively pressed after plating. Soft plate selective plating process; electroplating thick copper NF PP press-filling process
b. Double-sided deep drilling process with high-precision drilling rig (contact induction current). After deep drilling, copper plating and mechanical blind hole process are required.
c. Multiple sets of differential, single-ended impedance process design; different layers of soft board and hard board impedance design.
e. Positive and negative laser + laser depth control process to improve open cover loss

 

 

 

5  Product application :

Intelligent wearable system for the collection and analysis of human health data.

The board is equipped with a human body contact sensing intelligent module, and is equipped with a soft and hard board to realize a light and convenient carrying design.
