RCY ELECTRONIC :Rigid-flex PCB new product release ( IV )
1 Product picture display
Application:Smart wearable system/Consumer electronics
layer count :4L
Min. hole size：0.2 mm
process difficulty：Flying tail structure, fixed depth drilling
3 Manufacturing 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.
