Hatisitsoeng oa potoloho boto (PCBS) ke maqephe a entsoeng ka fiberglass, li-resin tsa epoxy tse nang le likarolo tse ngata kapa lisebelisoa tse ling tse laminated. PCBS e ka fumanoa mefuteng e fapaneng ea likarolo tsa motlakase le tsa elektroniki (mohlala, li-buzzers, li-radio, li-radar, litsamaiso tsa likhomphutha, jj.). Mefuta e fapaneng ea PCBS e ka sebelisoa ho latela ts’ebeliso. What are the various types of PCBS? Bala ho tseba ho tseba.

What are the different types of PCBS?

PCBS are usually classified by frequency, number of layers used, and substrate. Mefuta e meng e tsebahalang e tšohloa ka tlase.

L PCB e le ‘ngoe

Single-sided PCB is the basic type of circuit board, consisting of only one layer of substrate or base material. Lera le koahetsoe ka tšepe e tšesaane, koporo, e leng mokhanni o motle oa motlakase. Li-PCBS tsena li boetse li na le lera le sireletsang la ho qhekella le sebelisitsoeng kaholimo ho lera la koporo hammoho le seaparo sa silika. Melemo e meng e fanoang ke PCBS e le ‘ngoe ke ena:

Single-sided PCB is used for mass production and low cost.

Li-PCBS tsena li sebelisoa lipotolohong tse bonolo joalo ka li-sensors tsa motlakase, li-relays, sensors le lintho tsa ho bapala tsa elektroniki.

L PCB e mahlakore a mabeli

Mahlakore ka bobeli a PCB e mahlakore a mabeli a na le likarolo tse tsamaisang tšepe. Likoti tsa boto ea potoloho li lumella likarolo tsa tšepe hore li hokahane ho tloha ka lehlakoreng le leng ho ea ho le leng. These PCBS are connected to the circuit on either side by either through-hole or surface-mount techniques. Mokhoa oa ho phunya lesoba o kenyelletsa ho fetisetsa kopano ea pele ka lesoba le seng le phunngoe ka lebokoseng ebe oe cheselletsa padeng ka lehlakoreng le leng. Ho hloa bokaholimo ho kenyelletsa ho beha likarolo tsa motlakase ka kotloloho holim’a boto ea potoloho. Li-PCBS tse mahlakore a mabeli li fana ka melemo e latelang:

Ho hloa bokaholimo ho lumella lipotoloho tse ngata hore li hokahane le boto ho feta ka ho hloa masoba.

Li-PCBS tsena li sebelisoa haholo lits’ebetsong tsa mehala ea mohala, ho lekola matla, lisebelisoa tsa liteko, li-amplifiers le lits’ebetso tse ling tse ngata.

L multilayer PCB

PCB ea multilayer ke boto e hatisitsoeng ea potoloho e nang le likarolo tse fetang tse peli tsa koporo, joalo ka 4L, 6L, 8L, jj. Li-PCBS tsena li holisa theknoloji e sebelisoang ho li-PCBS tse mahlakore a mabeli. Lithako tsa substrate le insulation li arola likarolo ho PCB e nang le mekhahlelo e mengata. PCBS are compact in size and offer weight and space advantages. Melemo e meng e fanoang ke li-PCBS tse ngata ke:

Li-PCBS tse mekato e mengata li fana ka maemo a holimo a ho tenyetseha ha moralo.

Li-PCBS tsena li bapala karolo ea bohlokoa lipotolohong tse lebelo. Li fana ka sebaka se eketsehileng bakeng sa lipaterone tsa mokhanni le mehloli ea matla.

L thata PCB

Li-PCBS tse thata ke tse entsoeng ka lintho tse thata ‘me li ke ke tsa kobeha. Melemo e meng ea bohlokoa eo ba fanang ka eona:

Li-PCBS tsena li kopane, ho netefatsa hore ho entsoe mefuta e fapaneng ea lipotoloho tse rarahaneng.

Li-PCBS tse thata li bonolo ho li lokisa le ho li hlokomela hobane likarolo tsohle li tšoailoe ka ho hlaka. Ho feta moo, litsela tsa lipontšo li hlophisitsoe hantle.

L PCB e feto-fetohang

Tenyetsehang PCB e hahiloe holim’a thepa tenyetsehang botlaaseng. These PCBS are available in single-sided, double-sided and multi-layer formats. Sena se thusa ho fokotsa ho rarahana kahare ho likarolo tsa sesebelisoa. Some of the advantages these PCBS offer are:

Li-PCBS tsena li thusa ho boloka sebaka se ngata le ho fokotsa boima ba boto ka kakaretso.

Flexible PCBS help reduce board size and are therefore ideal for a variety of applications requiring high signal routing density.

Li-PCBS tsena li etselitsoe maemo a ts’ebetso moo ho nahanoang mocheso le letsoalo.

L Rigid – e tenyetsehang -PCB

Rigid flexible – A PCB is a combination of rigid and flexible circuit boards. They consist of multiple layers of flexible circuits connected to more than one rigid plate.

These PCBS are precisely constructed. Ka lebaka leo, e sebelisoa lits’ebetsong tse fapaneng tsa bongaka le tsa sesole.

Li-PCBS tsena li bobebe, li boloka ho fihlela 60% ea boima le sebaka.

L maqhubu a phahameng a PCB

Hf PCBS are used in the frequency range of 500MHz to 2GHz. Li-PCBS tsena li ka sebelisoa lits’ebetsong tse fapaneng tsa maqhubu a bohlokoa, joalo ka lits’ebetso tsa likhokahano, microwave PCBS, microstrip PCBS, jj.

L Aluminium mokokotlo oa PCB

Lipoleiti tsena li sebelisetsoa lits’ebetso tse nang le matla a maholo hobane sebopeho sa aluminium se thusa ho felisa mocheso. Aluminium e tšehelitsoeng ka Aluminium e tsejoa e na le maemo a phahameng a ho tenyetseha le maemo a tlase a phallo ea mocheso, e li etsang hore li be ntle bakeng sa lits’ebetso tse nang le mamello e phahameng ea mochini. PCB e sebelisetsoa phepelo ea LED le phepelo ea motlakase.

Tlhokahalo ea PCBS e ntse e ts’oara liindasteri kaofela. Kajeno, o tla fumana bahlahisi le barekisi ba PCB ba tsebahalang ba ka fihlelang litlhoko tsa mmaraka oa thepa e amanang le tlholisano. Kamehla ho khothalletsoa ho reka li-PCBS bakeng sa ts’ebeliso ea liindasteri le tsa khoebo ho tsoa ho bahlahisi le barekisi ba nang le botumo bo botle.
