PCB FABRICATION
FABRICATION SINGLE SIDED, DOUBLE SIDED,
MULTI LAYER BOARDS (UPTO 16 LAYERS) AND FLEX PCBS (PRINTED CIRCUIT BOARDS)
[CODE NO. 3178]
A PCB is a printed circuit board is used in electronics to build electronic devices. A PCB serves two purposes in the construction of an electronic device; it is a place to mount the components and it provides the means of electrical connection between the components.
PCBs are categorized in several ways according to
• Layer count
• Substrate
• Additive or subtractive technology
• Rigidity or flexibility.
According to layer count, the PCBs are classified into three main categories:
• Multilayer PCB
• Double-sided PCB
• Single-sided PCB.
PCBs are also categorized by substrates or base materials into three classes:
• Rigid PCB
• Flexible
• Rigid–flex.
Rigid PCBs are the most common type of PCBs especially when used to interconnect components. Flexible circuits are manufactured on polyimide and polyester substrates that remain flexible at finished thickness.
They allow 3D movements. Rigid–flex boards are assembly of rigid and flexible boards laminated together during the manufacturing process.
