Printed Circuit Board (PCB) Material is important. Usually a simple
circuit board comprises a substrate and a variety of electronic
components, Since 1931, Austrian Paul Eisler using the first block
printed circuit board in a radio device, till now,types of PCB
materials has become more and more abundant, like flexible circuit
board in use of polyimide woven glass fiber substrate for the
environment temperature which is rather high; circuit that adopts Teflon
glass fiber substrate for high frequency; metal substrate material
should be used for high heat dissipation requirements of electronic
products and so on.
So how to choose the appropriate type of pcb materail for your product? Generally the following factors should be considered when choosing PCB materials:
(1) to select the substrate material with appropriate temperature (Tg)
of the glass transition , Tg should be higher than the circuit operating
(2) low thermal expansion coefficient is required. Due to the
difference of thermal expansion coefficient among axis X, Y, and
thickness direction, it is easy to cause PCB material deformation, and
when it is serious, it will cause the metal hole breakage and component
(3) General high heat resistance is required. PCB with Heat resistance of 250 degrees /50S is required.
(4) Good flatness is required. SMT PCB warping degree should be less than 0.0075mm/mm.
(5) Material with high permittivity and small dielectric loss is
necessary in electrical performance of high frequency circuit.
Insulation resistance, voltage resistance, anti arc properties should
also meet the requirements of the products.
