3 Manufacturing flow:
FCCL Cutting->Drilling->Hole blacking->PTH->Inner circuit->Coverlay->FPC MASK->Brown Oxide->Bonding->laminating ->X-Ray drilling->
Hole Plating->resin plug hole ->outer circuit->solder mask->rigid flex opening>Immersion gold->Bonding->FPC UV lasering->E-TEST>outline>FQC
4 Process difficulties:
- The inner soft board anti-welding process.In addition, the inner soft board window Cover lays the tolerance, which needs to be made of soft board anti-welding ink.
However, the process needs to consider the external lamination heat and stress after the anti-welding. And realize the inner layer soft plate gold process design
2. In addition, HDI blind hole design, using first-order HDI+VOP process, laser hole filling after laser blind hole, resin plug hole process.
What’s more ,to meet the requirements of product design signal stability
3. Moreover, the resistance requirements, product design has a conductive network requirement for steel sheet and FPC.
However, low resistance value and stability requirements are achieved through material selection and pressing process optimization
5 Product application :
However, consumer Electronics 3C – Bluetooth voice module PCB. This board is used in true wireless Bluetooth headsets.
Besides,the part of the steel sheet is responsible for the user’s pressing and regulating the volume. And the intermediate IC part is responsible for Bluetooth signal reception.
What’s more, through the three-dimensional bending, the power supply is wrapped in the shape of the RF-PCB to realize the precision and fine structure assembly of the product.
However, SHENZHEN RENCHUANG YI ELECTRONIC CO.,LTD ( Short as RCY ELECTRONIC)
is a professional and trusted pcb manufacturer in Shenzhen, China, specialises in multilayer pcb, HDI pcb, and rigid-flex pcb
