In general, boards can be categorized into three categories: rigid, flex, or metal-core.
Standžios lentos are often the vast majority of boards a designer will encounter, where the layout of the board is contained within a rigid substrate created from a high heat and pressure lamination process. The common material for these boards is FR-4, but depending on the particular needs of the design, this can be modified to emphasize or otherwise improve certain characteristics of the board.
Lanksčios lentos yra komponuojama iš a mažiau standi medžiaga kad leidžia už toli didesnis deformacija. Medžiaga yra lytėjimas reminiscent iš a plėvelė ritinys, ir the board storis is paprastai far mažiau nei a standartinis standus lenta. Nors jie jau matyti pagrindinis naudojimas, ten yra viltis kad lanksčios lentos bus usher in the next step of wearable technology and remove the current planar constraints inherent to rigid board devices.
A metalo šerdis PCB yra kažkas iš an offshoot of rigid board designs, with an increased ability to dissipate heat throughout the board to protect sensitive circuitry. This style can be an option for high-current designs to prevent thermal wear and failure.
