Ishicilelwe ibhodi yesekethe (PCBS) ziimakhishithi ezenziwe nge-fiberglass, i-resin epoxy resins okanye ezinye izinto ezilaminethiweyo. I-PCBS inokufumaneka kwizinto ezahlukeneyo zombane neze-elektroniki (umzekelo, ii-buzzers, iiradiyo, iiradars, iinkqubo zekhompyuter, njl. Iindidi ezahlukeneyo zePCBS zinokusetyenziswa ngokuxhomekeke kwisicelo. What are the various types of PCBS? Funda ukuze ufumane.

What are the different types of PCBS?

PCBS are usually classified by frequency, number of layers used, and substrate. Ezinye iintlobo ezidumileyo zixutyushwa ngezantsi.

L PCB enamacala amabini

Single-sided PCB is the basic type of circuit board, consisting of only one layer of substrate or base material. Uluhlu logqunywe ngentsimbi encinci, ubhedu, ongumqhubi wombane olungileyo. Ezi PCBS ziqulathe umaleko okhuselekileyo wokumelana nomaleko osetyenziselwa phezulu kumaleko obhedu ngokudibeneyo nokwaleka kwesilika. Ezinye zeenzuzo ezibonelelwa ngamacala amabini e-PCBS zezi:

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

Ezi PCBS zisetyenziswa kwiisekethi ezilula ezinje ngeegesi zamandla, ukuhanjiswa, iisenzi kunye nezinto zokudlala zekhompyuter.

L double-sided PCB

Omabini amacala e-PCB enamacala amabini anezinto zokuhambisa zentsimbi. Imingxunya kwibhodi yesekethe ivumela iinxalenye zesinyithi ukuba zidityaniswe ukusuka kwelinye icala ukuya kwelinye. These PCBS are connected to the circuit on either side by either through-hole or surface-mount techniques. Inkqubo yokufaka umngxunya kubandakanya ukudlula kwindibano ekhokelayo ngomngxunya owenziwe kwangaphambili ebhodini emva koko uyidibanise nephedi kwelinye icala. Ukunyusa umphezulu kubandakanya ukubeka izinto zombane ngokuthe ngqo kumphezulu webhodi yesekethe. Amacala amabini e-PCBS abonelela ngezi zinto zilandelayo:

Ukunyusa umphezulu kuvumela imijikelezo engaphezulu ukuba idityaniswe ebhodini kunakwindawo yokufaka umngxunya.

Ezi PCBS zisetyenziswa ngokubanzi kwiinkqubo zefowuni eziphathwayo, ukujonga amandla, izixhobo zovavanyo, izikhulisi kunye nezinye izinto ezininzi.

L multilayer PCB

I-PCB ye-multilayer yibhodi yesekethe eprintiweyo ebandakanya ngaphezulu kweebini zobhedu, ezinje nge-4L, 6L, 8L, njl. Ezi PCBS zandisa itekhnoloji esetyenziswe kwi-PCBS esecaleni. Ubume be-substrate kunye nokugquma buyahlula ngokwahlulahlula kwi-PCB eyahlukeneyo. PCBS are compact in size and offer weight and space advantages. Ezinye zeenzuzo ezibonelelwa zii-multilayer PCBS zezi:

Uluhlu lwee-PCBS ezininzi lubonelela ngezinga eliphezulu lokuguquguquka koyilo.

Ezi PCBS zidlala indima ebalulekileyo kwiisekethe ezinesantya esiphezulu. Banikezela ngakumbi ngendawo yeepateni zabaqhubi kunye nemithombo yamandla.

L PCB engqongqo

Ii-PCBS ezinzima zezo zenziwe ngezinto eziqinileyo kwaye azinakugotywa. Ezinye zezibonelelo ezibalulekileyo abazibonisayo:

Ezi PCBS zihambelana, ziqinisekisa ukuba iintlobo ngeentlobo zeesekethe ezenziweyo ziyangqongile.

Ii-PCBS ezilukhuni zilula ukuzilungisa kunye nokuzigcina kuba zonke izinto ziphawulwe ngokucacileyo. Ngaphaya koko, iindlela zomqondiso zilungelelaniswe kakuhle.

L I-PCB eguqukayo

I-Flexible PCB yakhelwe kwizinto ezisisiseko eziguquguqukayo. These PCBS are available in single-sided, double-sided and multi-layer formats. Oku kunceda ukunciphisa ukuntsokotha ngaphakathi kwezinto zefowuni. Some of the advantages these PCBS offer are:

Ezi PCBS zinceda ukugcina indawo eninzi kunye nokunciphisa ubunzima bebhodi iyonke.

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

Ezi PCBS ziyilelwe iimeko zokusebenza apho ubushushu kunye noxinano luthathelwa ingqalelo.

L Ngqongqo-eguqukayo -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. Ngenxa yoko, isetyenziselwa iindlela ezahlukeneyo zonyango kunye nezomkhosi.

Ezi PCBS zilula, zigcina ukuya kuthi ga kwi-60% yobunzima kunye nendawo.

L iphindaphindwe nge-PCB

Hf PCBS are used in the frequency range of 500MHz to 2GHz. Ezi PCBS zinokusetyenziswa kwizicelo ezahlukeneyo zokuhamba rhoqo, ezinje ngeenkqubo zonxibelelwano, i-microwave PCBS, i-microstrip PCBS, njl.

L I-Aluminium yeplani yePlanethi

Ezi iipleyiti zisetyenziselwa usetyenziso lwamandla aphezulu kuba isakhiwo sealuminium sinceda ukutshabalalisa ubushushu. IAluminiyam exhaswa yi-PCBS yaziwa ngokuba nenqanaba eliphezulu lokuqina kunye namanqanaba asezantsi okusasazeka kwe-thermal, okwenza ukuba kube lula kwizicelo ezinokunyamezelana okuphezulu koomatshini. I-PCB isetyenziselwa ukuhambisa umbane nge-LED.

Ibango le-PCBS lifikelela kumashishini onke. Namhlanje, uya kufumana iintlobo ezahlukeneyo zabenzi be-PCB kunye nabasasazi abanokuhlangabezana neemfuno zentengiso yezixhobo ezinokhuphiswano. Kuhlala kucetyiswa ukuba kuthengwe ii-PCBS kusetyenziso lweshishini kunye nentengiso kubavelisi abanesidima nabathengisi.
