Iindidi ezahlukeneyo zeebhodi zeesekethe

The ibhodi yesekethe eprintiweyo okanye i-PCB yibhodi yenkxaso ebonakalayo ngelixa idibanisa ngombane amacandelo ahlukeneyo ombane wenkqubo ebanzi. Ibhodi yesekethe isebenzisa i-wiring conductive, i-padding kunye nezinye izinto eziphuma kwi-copper layer.

Icala elinye

Njengoko igama libonisa, iPCB enecala elinye yenziwe ngento enye, eyaziwa ngokuba yi “substrate.” On top of the base is a thin foil layer made of copper. Oku kusebenza njengomqhubi wemiqondiso yombane.

Ezi zezona ntlobo zixhaphakileyo ze-PCBS kwaye zithandwa kakhulu kwimveliso yevolumu ngenxa yexabiso labo eliphantsi. Ezi bhodi ziqhele ukufunyanwa kwiikhamera, iikhatyhuleyitha kunye nezixhobo zerediyo.

Zinokufumaneka nakwiziyilo ezilula zokudlala.

Amacala amabini

Iibhodi zesekethe eziprintiweyo ezinamacala amabini zisebenza kakhulu njengeebhodi zesekethe eziprintiweyo ezinecala elinye, kodwa zifakwe phakathi kweeleya zokuqhuba kumacala omabini. 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.

I-PCBS enamacala amabini ahlala efumaneka kwiifowuni eziphathwayo, oomatshini bokuthengisa, iimonitha zeemoto kunye nezixhobo zemitha yombane.

I-Multilayer

Uyilo lunamacala amabini kwaye lwandisa kuwo. I-multilayer yingqokelela engekho ngaphantsi kwesithathu (3) i-PCBS enamacala amabini. Bathatha itekhnoloji esekwe apha kwaye bandise umthamo wabo wemveliso.

Ubungakanani kunye nendawo zezona zinto ziluncedo kwi-PCBS yamanqanaba amaninzi. Bangasebenzisa ibhodi ye-multilayer endaweni yeebhodi ezininzi.

Ziyinxalenye ebalulekileyo yeesekethe zesantya esiphezulu kuba ubungakanani bebhodi yabo buvumela ukucwangciswa okufanelekileyo komqhubi kunye namandla.

Yenziwe lukhuni

Rigid PCBS can be single, double, or multi-layered. I-Rigidity ibhekisela kwi-substrate yezinto ezenziwe ngamabhodi. 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. Zenzelwe ukuba zihlale kwaye zinokusetyenziswa kwindawo enye kunye nokuma.

Rigid PCBS benefit from ease of maintenance and ease of use. Zonke iiprojekthi zinendawo kwaye ziphawulwe ngokucacileyo xa ziyilwa. Azikhawulelwanga kuyilo olunye kwaye zinokususela kumaleko omnye ukuya kwishumi (10) loyilo lwePCB.

thambile

PCBS Flexible ukusebenza ngendlela efanayo PCBS engqongqo, kodwa zenziwe ngezinto ezahlukeneyo.

Iipleyiti eziqinileyo zenziwe ngezinto ezihlala ixesha elide (ezithetha ukubamba imilo yazo) (ngokuqhelekileyo umxube we-fiberglass), ngelixa iipleyiti eziguquguqukayo zihlala zenziwe ngeplastiki okanye izinto ezifanayo.

Ukuguquguquka okucacileyo yeyona nto iluncedo kwiPCBS ebhetyebhetye. Ukongiwa kweendleko kunokwenzeka ngenxa yokukwazi kwabo “ukusonga” iindawo apho iipleyiti eziqinileyo zinokuhamba.

The main applications of flexible PCBS are in systems that may cause damage to the environment. Uyilo lwazo luzenza zikwazi ukumelana nobushushu, amanzi, umhlwa kunye nezinye izinto ezinokuthi zonakalise iipleyiti eziqinileyo.

Mixing and soft

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

Ezi ziquka isethi yeesekethe eziguquguqukayo ezixhunywe kwiipleyiti ezininzi eziqinileyo. Oku kwenza ukuba uyilo lube lula ngakumbi, njengoko ludibanisa zonke izinto ezifunekayo kula malungu zibe yinxalenye “enye”.

Ukuqina kunye nokuguquguquka kunokufumaneka kwizicelo zonyango.

Aluminiyam ngasemva

Ukutshatyalaliswa kobushushu kungundoqo kwi-PCB. Xa ubushushu benkqubo buqwalaselwa, ukusebenzisa i-aluminium backboard PCB lolona khetho lungcono, olubandakanya ezinye izibonelelo ezicacileyo.

Ulwakhiwo lwePCB luyafana nomgangatho omnye okanye umaleko ophindwe kabini, kodwa izinto ezisetyenziswayo zahlukene.

Zihlala ixesha elide kwaye zinobuhlobo kakhulu nokusingqongileyo. Ialuminiyam ayinayo ityhefu kwaye kulula kakhulu ukuyiphinda isetyenziswe. On top of that, it’s incredibly cheap, it’s one of the cheapest metals in mining, and it’s cheap to make.

Ukuhamba rhoqo

I-Hf PCBS ayakhiwanga ngendlela entsha, umzekelo, ukuthelekisa enye ukuya kwiileya ezininzi, kodwa bhekisa kuhlobo losetyenziso. I-PCBS yefrikhwensi ephezulu ingasetyenziswa xa imiqondiso ifuna ukuhanjiswa kumazinga aphezulu kuno-1GHz. They are mainly used in large communication systems.

Iingenelo zokusebenzisa iPCB

Nangona uhlobo ngalunye lwebhodi luneenzuzo zalo, kukho iinzuzo ezininzi ekusebenziseni i-PCB ngokubanzi.

Easy trouble shooting and maintenance

Indlela emiswe ngayo ibhodi, okanye “umkhondo,” webhodi yenza kube lula ukubona izixhobo eziyingxaki uze uzibuyisele endaweni yazo

Remove and reattach to board

Ukusebenza kakuhle kwe: Akukho mfuneko yokuphinda kwakhiwe isiphaluka sonke xa kulungiswa okanye kusenziwa utshintsho

Ibhodi yesekethe sisicwangciso esenziwe kwangaphambili kwaye kuthatha ixesha elincinci kakhulu ukwakha kuneesekethe zemveli

Ingxolo ephantsi: Uyilo lwePCB oluyilwe ngokufanelekileyo lunokukhokelela kwizinto zombane ezinemitha ephantsi, eyaziwa ngokuba “yintetho enqamlezileyo.”

Inceda ukuphelisa ingxolo ye-elektroniki enokuthomalalisa ukusebenza kwesixhobo

ukuthembeka: Ngoko ke, ukudityaniswa kwebhodi kufakwe ngocingo lobhedu. Akukho ziqhagamshelo zixengaxengayo okanye “iingcingo ezishukumayo.”

I-welding idibanisa zonke iinqununu kwibhodi ngokwayo, ngoko zisebenza nokuba ibhodi iyasuswa.
