RCY ELECTRONIC :Rigid-flex PCB new product release ( II)
1 Product picture display
Application:industrial camera/Industrial control
layer count :12L
Min. hole size：0.2 mm
process difficulty：metal groove on the side, high and multilayer Stackup
3 Manufacturing flow:
FCCL Cutting->Drilling->Inner circuit->Coverlay->Brown Oxide->Bonding->laminating ->Panel PTH->
outer circuit->pattern PTH->Etching>solder mask->Immersion gold->FPC UV lasering->E-TEST->Outline->FQC
4 Process difficulties:
a. Material selection, industrial control, use DuPont AP series material PI 100um, copper thickness 35um; high TG NF PP + core board material selection.
b. High multi-layer NF PP pressing process, NF PP thick copper pressure-filling process, open cover structure design.
c. Multiple sets of differential, single-ended impedance process design; different layers of soft board and hard board impedance design.
d. The side metal groove process uses an alkaline etching process to improve the metal burr problem.
e. Solder-resistant black oil dense BGA (0.25mm) process.
f. Positive and negative laser + mechanical control deep processing, to meet the thick cover open cover design
5 Product application :
Industrial camera vision system for HD, precision, dynamic image acquisition and intelligent identification systems.
However,the BGA position of the board includes a camera acquisition processing chip and a memory chip.
In addition, dynamic control through vertical soft and hard plate bending design, three-dimensional structure assembly
