Kutheni le i-cailper foil isetyenziswe kwimveliso ye-PCB?

Iibhodi zesekethe eziprintiweyo zizinto eziyimfuneko zezixhobo zombane. I-PCBS yanamhlanje inezingxwaba zalo: i-substrate, umkhondo, imaski yomthengi, kunye nesilika. Esona sixhobo sibalulekileyo kwi-PCB ngobhedu, kwaye kukho izizathu ezininzi zokuba kutheni kusetyenziswa ngobhetele endaweni yabanye abantu be-alloys njenge-aluminium okanye i-tin.

Yintoni i-PCBS?

Ichazwe yinkampani yendibano yePCB, i-PCBS yenziwa ngento ebizwa ngokuba yindawo engumhlaba, eyenziwe nge-fiberglass eqiniswe nge-Epoxy Retin. Ngaphezulu kwe-substrate i-suble ye-foil yobhedu enokudinwa kumacala omabini okanye enye kuphela. Nje ukuba kwenziwe umhlaba, abavelisi babeke izinto ezikhoyo. Basebenzisa imaski yomthengi kunye ne-Silkscreen kunye nabaphathi, abasebenzi, abathwele, ii-Deds, i-chips zesekethe, kunye nezinye izinto ezizodwa.

Kutheni le i-cailper i-cail isetyenziswe kwii-PCB?

Abavelisi be-PCB basebenzise i-Popper kuba inomsebenzi obalaseleyo wombane kunye nemvukelo. Njengoko i-shop yombane ihamba kunye ne-PCB, ubhedu lugcina ubushushu buvela kwingozi kwaye bucinezele i-PCB yonke. Ngolunye uhlobo lwe-alloys-njenge-aluminium okanye i-tin - i-PCB inokugcina ngokungalinganiyo kwaye ayisebenzi kakuhle.

Ubhedu yinto ekhethiweyo kuba inokuthumela imiqondiso yombane kwiBhodi ngaphandle kweengxaki zokulahlekelwa okanye ukunciphisa umbane. Ukusebenza kakuhle kobushushu kudlulisa abavelisi ukuba bafake ubushushu be-classic ejingayo kumphezulu. Ubhedu ngokwalo lusebenza ngokufanelekileyo, njengoko i-ounce yobhedu inokugubungela inyawo le-PCB kwi-1.4 amawaka ee-intshi okanye ii-micrometer ezingama-35 ezinkulu.

Ubhedu lukhule kakhulu kuba ine-elektroni yasimahla enokuhamba ukusuka kwenye iatom ukuya kwelinye ngaphandle kokucothiswa. Kuba ihlala isebenza ngokufanelekileyo kulowo nqanaba lincinci elincinci njengoko lisenza ngamanqanaba amancinci, ubhedu oluncinci luhamba ixesha elide.

Ubhedu kunye nezinye izinyithi ezixabisekileyo ezisetyenzisiweyo kwii-PCBs
Uninzi lwabantu luyaqonda i-PCBs njengeGreen. Kodwa, zihlala zinemibala emithathu kungqingo lwangaphandle: igolide, isilivere, kwaye ibomvu. Banayo nobhedu olumsulwa ngaphakathi nangaphandle kwePCB. Ezinye izinyithi kwibhodi yesekethe zibonisa ngemibala eyahlukeneyo. I-Golder yeGolide yeyona ibiza kakhulu, i-style theter inendleko yesibini ephakamileyo, kwaye ibomvu yeyona nto iphambili.

Sebenzisa igolide yokuntywila kwi-pcbs
Ubhedu kwiBhodi yeSekethe eprintiweyo

Umaleko wegolide osetyenziselwa i-chanchct Shrapnel kunye neepads zecandelo. Ukungqinwa kwegolide esebenzayo ukuthintela ukufuduswa kweeathom zomphezulu. Umaleko ayisiyo golide, kodwa yenziwa ngegolide. Igolide icekeceke kodwa yanele ukwandisa ixesha lobomi bezinto ekufuneka zithengiswe. Igolide ithintela amalungu orhwebi ukusuka ekuveleni kwexesha.

Sebenzisa isilivere yokuntywila kwi-pcbs
Isilivere yenye yentsimbi esetyenziswe kwimveliso ye-PCB. Ingabizi kakhulu kunentywili yegolide. Ukuntywiliselwa kwesilivere kunokusetyenziswa endaweni yokuntywiliselwa kwegolide kuba iyanceda ukunxibelelana, kwaye inciphisa iindleko zeBhodi. Ukuntywila kwesilivere kuhlala kusetyenziswa kwii-PCBs ezisetyenziswa kwiimoto kunye neekhompyuter zekhompyuter.

I-Copper Clad i-lamote ye-PCBS
Endaweni yokusebenzisa ukuntywiliselwa, ubhedu lusetyenziswa kwifom ye-Clad. Lo ngumaleko obomvu we-PCB, kwaye yeyona ntsimbi isetyenziswa kakhulu. I-PCB yenziwa ngobhedu njengentsimbi yentsimbi, kwaye iyimfuneko yokufumana imijikelezo yokudibanisa nokuthetha nomnye ngokukuko.

Injani i-tiil yobhedu isetyenziswe njani kwi-PCBS?

Ubhedu lusebenzisa izibonelelo ezininzi kwii-PCBs, ukusuka kwi-Copper-Clad-Clad ukuya kumkhondo. Ubhedu lubalulekile kwi-PCBS ukuze usebenze ngokufanelekileyo.

Yintoni trice trace?
Umkhondo we-PCB yinto evakalayo, indlela yesekethe emamele. Umkhondo ubandakanya uthungelwano lobhedu, i-wiring, kunye nokufakelwa, kunye ne-fuse kunye nezinto ezisetyenziswa kwiBhodi.

Eyona ndlela ilula yokuqonda umkhondo kukucingela njengendlela okanye ibhulorho. Ukulungiselela izithuthi, umkhondo kufuneka ubenzi ngokwaneleyo ukubamba okungenani ezimbini kuzo. Kufuneka ibe nkulu ngokwaneleyo ukuba ingabi nakuphantsi koxinzelelo. Kananjalo kufuneka zenziwe ngezinto ezinokwazi ukumelana nobunzima bezithuthi ezihamba phezu kwayo. Kodwa, iitrato zenza konke oku ukuya kwinqanaba elincinci kakhulu lokuhambisa umbane kunokuba iimoto.

Izinto ze-pcb trace
Kukho izinto ezininzi ezenza umkhondo we-PCB. Banemisebenzi eyahlukeneyo ekufuneka yenziwe iBhodi ukuba yenze umsebenzi wayo ngokufanelekileyo. Ubhedu kufuneka lusetyenziselwe ukunceda umkhondo ukuba imisebenzi yabo, kwaye ngaphandle kwe-PCB, ngekhe sibe nazo izixhobo zombane. Khawufane ucinge ngehlabathi ngaphandle kwe-smartphones, iilaptops, abenzi bekofu, kunye neemoto. Yile nto besinokuyifumana ukuba i-PCBS ayisebenzisi ubhedu.

I-PCB TRACE YOKUGQIBELA
Uyilo lwe-PCB luxhomekeke kubungqingqwa beBhodi. Ubungqingqwa buya kuchaphazela ibhalansi kwaye buya kugcina izinto ezixhunyiwe.

Ububanzi bePCB trace
Ububanzi bomkhondo bize. Oku akuchaphazeli ibhalansi okanye iqhotyoshelwe amacandelo, kodwa igcina ukutshintshelwa kwangoku ngaphandle kokuthatha iBhodi.

I-PCB Trace okwangoku
I-PCB Trace okwangoku iyimfuneko kuba le yinto esetyenziswa yiBhodi ukuhambisa umbane ngamacandelo kunye neengcingo. Ubhedu lunceda oku kwenzeke, kwaye i-elektroni yasimahla kwi-Atom nganye ifumana i-sullly ihamba kakuhle ngaphezulu kweBhodi.

Kutheni i-foilper foil kwi-pcbs

Inkqubo yokwenza i-PCBS
Inkqubo yokwenza i-PCB iyafana. Ezinye iinkampani zenza ngokukhawuleza kunabanye, kodwa zonke zisebenzisa inkqubo efanayo nezixhobo. La ngamanyathelo:

Yenza isiseko ngaphandle kwe-fiberglass kunye ne-resins
Beka uluhlu lweendlela zokucwangcisa kwisiseko
Chonga kwaye usete iipateni zobhedu
Hlamba iBhodi kwindawo yokuhlamba
Yongeza imaski yomthengi ukukhusela i-PCB
Chaza i-Silkscreen kwi-PCB
Indawo kunye nomthengisi abaqeqeshayo, iisekethe ezihlanganisiweyo, abasebenzi kunye nezinye izinto
Vavanya i-PCB

I-PCBS idinga ukuba nezinto ezodwa ezikhethekileyo ukuze zisebenze ngokufanelekileyo. Enye yezona zinto zibalulekileyo ze-PCB ngubhedu. Le alloy iyafuneka ukuqhuba umbane kwizixhobo ezizakwe kuzo ii-PCBs. Ngaphandle kobhedu, izixhobo azizukusebenza kuba umbane awuyi kuba ne-alloy yokudlula.
