Mefuta e fapaneng ea liboto tsa potoloho

The boto ea potoloho e hatisitsoeng or PCB is the physical support board while electrically connecting the various electronic components of the wider system. Boto ea potoloho e sebelisa li-wiring tsa conductive, padding le lintho tse ling tse lumellanang le lera la koporo.

Lehlakore le le leng

Joalo ka ha lebitso le bontša, PCB e lehlakoreng le le leng e entsoe ka thepa e le ‘ngoe, e tsejoang hape e le “substrate.” Ka holim’a setsi ke lesela le tšesaane la foil le entsoeng ka koporo. Sena se sebetsa joalo ka conductor ea lipontšo tsa motlakase.

Tsena ke mefuta e atileng haholo ea PCBS mme e tumme haholo tlhahiso ea molumo ka lebaka la theko ea eona e tlase. Hangata liboto tsena li fumanoa lik’hamera, li-calculator le thepa ea seea-le-moea.

Li ka boela tsa fumanoa ka mekhoa e bonolo ea lipapali.

Mahlakore a mabeli

Liboto tsa potoloho tse hatisitsoeng ka mahlakoreng a mabeli li sebetsa joalo ka liboto tsa potoloho tse hatisitsoeng ka lehlakore le le leng, empa li kopantsoe pakeng tsa likarolo tse tsamaisang mahlakore ka bobeli. In addition, they are designed to have holes drilled into the plate.

These holes are placed on the board to allow the circuit to be mounted on either side of the PCB or fed through the board. Additional flexibility and conductive surfaces allow double-sided materials to be used in more advanced applications.

Li-PCBS tse nang le mahlakore a mabeli li atisa ho fumanoa ka liselefouno, mechine ea thekiso, lisebelisoa tsa likoloi le lisebelisoa tsa metha ea motlakase.

Multilayer

Moqapi o na le mahlakore a mabeli ‘me o atoloha ho oona. Multilayer ke pokello ea li-PCBS tse mahlakoreng a mabeli tse seng ka tlase ho tse tharo (3). They take the technology established here and increase their production capacity.

Size and space are the main advantages of multi-layer PCBS. Ba ka sebelisa boto ea multilayer ho e-na le liboto tse ‘maloa.

Ke karolo ea bohlokoa ea lipotoloho tse lebelo le phahameng hobane boholo ba boto ea bona bo lumella sebopeho se nepahetseng sa conductor le matla.

E thata

Rigid PCBS can be single, double, or multi-layered. Rigidity e bolela thepa ea substrate eo mapolanka a entsoeng ho eona. When a PCB is rigid, it is, as the name implies, made of materials that resist distortion or deformation.

A very common rigid PCB is the motherboard on a computer. Li etselitsoe ho tšoarella ‘me li ka sebelisoa sebakeng se le seng le sebopeho.

Rigid PCBS benefit from ease of maintenance and ease of use. Merero eohle e na le sebaka ‘me e tšoailoe ka ho hlaka ha e entsoe. Ha li felle feela moralong o le mong mme li ka tloha ho lera le le leng ho isa ho meralo ea PCB e leshome (10).

tenyetsehang

flexible PCBS sebetsa ka tsela e tšoanang le PCBS thata, empa li entsoe ka thepa e fapaneng.

Lipoleiti tse thata li entsoe ka thepa e tšoarellang (e bolelang ho tšoara sebōpeho sa tsona) (hangata ke motsoako oa fiberglass), ha lipoleiti tse tenyetsehang hangata li entsoe ka polasetiki kapa lisebelisoa tse tšoanang.

Ho feto-fetoha ha maemo ke molemo o ka sehloohong oa PCBS e tenyetsehang. Ho boloka litšenyehelo hoa khoneha ka lebaka la bokhoni ba bona ba ho “phuthela” libaka tseo lipoleiti tse thata li ka tlamehang ho tsamaea ho tsona.

The main applications of flexible PCBS are in systems that may cause damage to the environment. Moralo oa tsona o li etsa hore li se ke tsa hlola li futhumala, metsi, kutu le lintho tse ling tse ka senyang lipoleiti tse thata.

Ho kopanya le bonolo

Rigid-flexibility Bridges the gap between the two types built on text and graphics, which is most common in mobile phones and digital cameras.

Tsena li kenyelletsa sehlopha sa li-circuits tse feto-fetohang tse hokahantsoeng le lipoleiti tse ngata tse thata. Sena se etsa hore moralo o be bonolo le ho feta, kaha o kopanya likarolo tsohle tse hlokahalang bakeng sa likarolo tsena hore e be karolo “e le ‘ngoe”.

Ho thatafala le ho tenyetseha le tsona li ka fumanoa lits’ebetsong tsa bongaka.

Aluminium morao

Phallo ea mocheso e bohareng ba PCB. Ha mocheso oa tsamaiso ke ho nahanela, ho sebelisa aluminium backboard PCB ke khetho e ntle ka ho fetisisa, e kenyelletsang melemo e meng e totobetseng.

Sebopeho sa PCB se batla se tšoana le sekhahla se le seng kapa se habeli, empa lisebelisoa tse sebelisoang li fapane.

Li tšoarella haholoanyane ebile li na le botsoalle haholo tikolohong. Aluminium ha e chefo ebile e bonolo haholo ho e sebelisa hape. On top of that, it’s incredibly cheap, it’s one of the cheapest metals in mining, and it’s cheap to make.

Lebelo le phahameng

Hf PCBS ha e ea hahuoa ka mokhoa o mocha, mohlala, ho bapisa e le ‘ngoe ho mekhahlelo e mengata, empa e bua ka mofuta oa tšebeliso. PCBS ea maqhubu a phahameng e ka sebelisoa ha matšoao a hloka ho fetisoa ka litefiso tse fetang 1GHz. They are mainly used in large communication systems.

Melemo ea ho sebelisa PCB

Le hoja mofuta o mong le o mong oa boto o na le melemo ea oona, ho na le melemo e mengata ea ho sebelisa PCB ka kakaretso.

Easy trouble shooting and maintenance

Sebopeho, kapa “trace,” ea boto e etsa hore ho be bonolo ho khetholla thepa e nang le bothata le ho e nkela sebaka

Remove and reattach to board

Ho sebetsa hantle ha: Ha ho hlokahale ho tsosolosa potoloho eohle ha ho etsoa litokiso kapa liphetoho

Boto ea potoloho ke moralo o entsoeng esale pele ‘me o nka nako e nyane haholo ho aha ho feta lipotoloho tsa setso

Low lerata: Sebopeho se entsoeng hantle sa PCB se ka lebisa ho likarolo tsa motlakase tse nang le mahlaseli a tlaase, tse tsejoang e le “cross talk.”

E thusa ho felisa lerata la elektroniki le ka theolang tšebetso ea sesebelisoa

tšepahala: Therefore, the connection of the board is inlaid with copper wire. Ha ho na likhokahano tse hlephileng kapa “lithapo tse sisinyehang.”

Ho tjheseletsa ho kopanya likarolo tsohle ho boto ka boeona, kahoo li sebetsa le haeba boto e sisinyeha.
