Umzi-mveliso we-PCB uchithe ixesha elininzi ephuhlisa izixhobo ezibonelela ngelahleko ephantsi. Kwisantya esiphezulu kunye ne-Refloquency Deces, ilahleko iya kumka umgama wokusasaza umgama kunye nemiqondiso yokugqwetha, kwaye iya kudala ukuphambuka okunokubonwa kwimilinganiselo ye-TDR. Njengoko siyila nayiphi na iBhodi yeSiphaluka eprintiweyo kwaye siphuhlise isepheshana esebenza kwizantya eziphakamileyo, kunokuba lilingane ukukhetha ubhedu olunokwenzeka kulo lonke uloyilo olwenzileyo.

Nangona kuyinyani ukuba ukrokrela kobhedu kudala ukuphambuka kunye nokulahleka, kulula kangakanani na ubhedu lwakho? Ngaba zikho iindlela ezilula onokuzisebenzisa ukoyisa ilahleko ngaphandle kokukhetha i-Ultra-fity yobhedu yonke uyilo? Siza kujonga la manqaku kweli nqaku, kunye nento onokuyijonga ukuba uqala ukuthenga izilwanyana ze-PCB.

Iintlobo zeI-PCB Copper ye-PCB

Ngokwesiqhelo xa sithetha ngobhedu kwizinto ze-PCB, asithethi ngohlobo oluthile lobhedu, sithetha kuphela ngoburharha. Iindlela ezahlukeneyo zokucwangciswa kobhedu ivelise iifilimu ezinamaxabiso ahlukeneyo okuba rhabaxa, enokwahlula ngokucacileyo kwimifanekiso ye-elektroni ye-elektroni (i-SM). Ukuba uza kusebenza kwi-RESTEENTES ephezulu (ngesiqhelo i-5 GHz WIFI okanye ngasentla) okanye ngesantya esiphezulu, emva koko unikele ingqalelo kuhlobo lobhedu oluchaziweyo kwidatha yedatha yakho.

Qiniseka ukuba uyayiqonda intsingiselo yamaxabiso e-DK kwidatasheet. Bukela le ngxoxo ye-Podcast kunye noJohn Coodod ukusuka eRogers ukuba ifunde ngakumbi malunga neenkcazo zeDK. Ngale nto engqondweni, makhe sijonge ezinye zeentlobo ezahlukeneyo ze-PCB Copper foil.

I-electroded

Kule nkqubo, idrum isuswe isisombululo sesisombululo se-electrolytic, kwaye intetho ye-electrovide isetyenziselwa "ukukhulisa" ukuvela kobhedu kwiDrum. Njengoko i-Drum ijikeleza, ifilimu yobhedu ephekiweyo ihamba kancinci kwi-roller, inika iphepha eliqhubekayo lobhedu olunokuthi liqengqiwe kamva. Icala ledrum lobhedu liza kutshatisa uburharha be-Drum, ngelixa icala elicacileyo liya kuba luphawu oluninzi.

I-PCB ye-PCB ye-PCB

Ukuveliswa kwemveliso yobhedu.
Ukuze isetyenziswe kwinkqubo yokufunda i-pcb ye-pcb ye-PCB, icala eliqaqambileyo lobhedu liza kuqala lidinwe kwisidlo se-reseclin seglasi. I-Copper eseleyo (icala leDrum) liya kufuna ukuba liqengqelwe ngobuchule (umz. Oku kuyakuqinisekisa ukuba kungabhalwa kwi-bitter elandelayo kwi-PCB stackup.

I-terroded ye-elektroniki ephathwayo

Andazi eli gama libalaseleyo elibandakanya zonke iintlobo ezahlukeneyo zomhlaba ophathwayoIifayile zobhedu, ngaloo ndlela isihloko singentla. Ezi zixhobo zobhedu zaziwa ngokuba ziintshaba eziphathwayo, nangona ezinye izinto ezimbini ziyafumaneka (jonga ngezantsi).

I-Revernerd ii-foils zisebenzisa unyango lomphezulu osetyenziswa kwicala eligudileyo (icala lesigulana) lephepha le-electroded. Umanyano lonyango ngumkhenkce nje onqabileyo ocinga ngobhedu, ngoko ke uya kuba nobumbiso obukhulu kwizinto ze-diadic. Olu nyango lusebenza njengesithintelo se-oxidotion esithintela ukususwa. Xa le ndlela yobhedu isetyenziselwa ukwenza iipaneli ze-lamite, icala eliphathwayo ligcwele i-diecric, kunye necala elinqabileyo lingabonakali. Icala elibonisiweyo aliyi kufuna nayiphi na into eyongezelelweyo ngaphambi kokuba i-etch; Iza kuba namandla aneleyo okuya kwi-suble elandelayo kwi-PCB stackup.

Umahluko wesithathu kwi-reverser foil ithwalwe i-foil yobhedu ibandakanya:

Iqondo lokushisa eliphezulu (HTE) Copper Foil: Le yi-elektroniki ye-electrodiyo ehambelana ne-IPC-4562 yeBanga lesi-3. Ubuso obutyhiliweyo bukwaphathwa ngesithintelo se-oxidition ukuthintela i-corrosion ngexesha lokugcina.
I-foil ephathelwe kabini: Kule fore i-foil, unyango lusetyenziswa kuwo omabini amacala efilimu. Ezi zixhobo ngamanye amaxesha zibizwa ngokuba zidrum-icala elihluthwe i-foil ephathwayo.
Ukunganyangeki: Oku akuqhelekanga ukubanjwa njengobhedu oluphawulweyo. Le foilper foil isebenzisa i-metallic i-mestellic kwicala le-Matte yobhedu, emva koko ikhutshelwe kwinqanaba elifunayo.
Isicelo sonyango lomphezulu kwezi zixhobo zobhedu zithe tye: I-Foil iqengqele iibhafu ezongeziweyo ezisebenzisa ukubekwa kobhedu, ilandelwa ngumqobo wefilimu, kwaye ekugqibeleni ifilimu yefilimu.

I-PCB Copper ye-PCB

Iinkqubo zonyango ezingaphezulu ze-foild yeendlela zobhedu. [Umthombo: IPytel, Steven G., et al. "Uhlalutyo lonyango lobhedu kunye neziphumo kwisasazi yomqondiso." Ngo-2008 amacandelo eNkomfa ye-elektroniki kunye neNkomfa yeTekhnoloji, iphe. 1144-1149. IEEE, 2008.
Ngale nkqubo, unesixhobo esinokusetyenziswa ngokulula kwinkqubo yeBhodi yeBhodi esemgangathweni.

Uqengqeleka ubhedu

I-ron-ron-ronped foils iya kudlulisa i-roll ye-foil ye-callper ye-rollers, eya kuthi ibandezeleke iphepha lobhedu. Ubunzima bephepha lemithombo elinokubakho luya kwahluka ngokuxhomekeka kwiiparamitha eziqengqelekayo (isantya, uxinzelelo, njl. Njl.).

Iphepha elinemiphumo linokugudisa kakhulu, kwaye imichiza ibonakala kumphezulu wephepha lobuqhetseba. Imifanekiso ingezantsi ibonisa ukuthelekisa phakathi kwe-elektroniki yobhedu

Ubhedu olusezantsi
Oku akunyanzelekanga ukuba luhlobo lobhedu Ubhedu oluphantsi lweprofayile yi-electroded yobhedu ophathwayo kwaye iguqulwe ngenkqubo ye-roboting encinci yokubonelela ngomgangatho ophakathi ophantsi olwenziweyo nge-subthen. Iinkqubo zokwenza la magama obhedu iqhele ukungqubana. La magama ahlala ahlulwe njengeprofayile ye-Ultra (ilp), iprofayile ephantsi kakhulu (i-VLP), kunye neprofayile encinci (i-LP, i-1 microron iphakathi).
