Pcb Board Material Name. These are commonly referred to as copperclad laminates. Normally all pcb base material used by weller conform to ipc4101 specification for base materials for rigid and multilayer printed boards and ul certificated.
The table below is an extract of certain characteristics from ipc 4101 classifications highlighting some of the details already referenced. When pcb is not developed at that time all components are connected with a wire which increases complexity and decreases reliability of the circuit by this way we cannot make a very large circuit like motherboard. Fr 4 this is the most commonly used material in pcbs.
Pcb generally consists of four layers which are heat laminated together into a single layer.
The last of those layers substrate is made of fiberglass and is also known as fr4 with the fr letters standing for fire retardant. Pcb trade names aceclor. Components are generally soldered onto the pcb to both electrically connect and mechanically fasten them to it. When ordering a copper clad laminate board the fr 4 and copper thickness can both vary and so are specified separately.
