RCY ELECTRONIC :Rigid-flex PCB new product release ( V )
1 Product picture display
Application:industrial camera/ Communication electronics
layer count :8L
Min. hole size：0.2 mm
process difficulty：High multi-laminate, short slot process, small BGA process
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, communication class, choose DuPont material PI 50um, copper thickness 18um; high TG NF PP+FR4 material, DF<0.002.
b. High multi-layer NF PP pressing process, positive and negative control deep open cover structure design; NF PP laser window opening, CORE plate laser counter control deep, mechanical control deep open cover.
c. Short slot hole process, this board has short slot hole deformation problems, which is improved by optimizing the drilling resolution.
d. Anti-welding black oil dense BGA (0.25mm) process, matte black oil, soft and hard board ink printing uneven improvement.
e. Multiple sets of differential, single-ended impedance process design, different layers of soft board and hard board impedance design.
5 Product application :
Industrial control system for industrial control dynamic sensing, integrated high-speed imaging chip, dynamic scanning, image acquisition
