Flexible Circuit Boards (FCBs) have become the core components of many innovative products. From smart watches to foldable phones, from medical devices to automotive electronics, FCBs are used everywhere. With the continuous advancement of technology, the requirements for FCB materials are also increasing.
This article explores the history and development of
As technology advances, PCB design and manufacturing processes have become increasingly complex, all of which rely heavily on the selection of core materials. The choice of materials directly impacts the reliability, durability, and cost of the PCB. Therefore, selecting the right materials is a critical step in PCB design and
PCB materials types included HB sheet and V0 sheet
HB sheet has low flame retardancy and is mostly used for single-layer PCB. VO sheet has high flame retardancy. It is mostly used in double-sides and multi-layer boards. This type of PCB sheet meets V-1 fire rating requirements and becomes FR-4 sheet.
When designing a PCB to factory fabrication, how to choose PCB material?
PCB material classification:
According to different materials (the most commonly used classification method)
Paper substrate (FR-1, FR-2, FR-3)
Epoxy glass cloth substrate (FR-4, FR-5)
Composite Substrates (CEM-1, CEM-3)
HDI sheet (RCC)
Special substrates (metal substrates, ceramic substrates, thermoplastic substrates, etc.)
Divided by resin
Phenolphthalein resin board
Epoxy board
Polyester
In recent months,PCB material cost is continual increase lead to China PCB enterprisers are in difficult situation. Especially price soared of copper foil,copper ball,glass fibre,epoxy resin have exceeded the limit of maximum cost of printed circuit enterprises. In pass 10 years, PCB enterprises have cut the price to bottom for
Some comments for select PCB materials:
For electronic products, using FR4 epoxy fiberglass materials.
For high temperature application or flexible circuit board, using polyimide materials.
For high-frequency circuit, using Rogers or Teflon materials.
For high heat dissipation products, using metal core materials,like Al based material.
Five factors we should consider when
