Kuki Copper Foil ikoreshwa mu gukora PCB?

Ibibaho byacapwe bya circuit ni bimwe mu bigize ibikoresho byinshi by'amashanyarazi. Ibikoresho bya PCB byo muri iki gihe bifite ibice byinshi: substrate, traces, solder mask, na silkscreen. Kimwe mu bikoresho by'ingenzi kuri PCB ni umuringa, kandi hari impamvu nyinshi zituma umuringa ukoreshwa aho gukoresha izindi alloys nka aluminiyumu cyangwa icyuma.

PCB zikozwe n'iki?

Nk’uko bivugwa n’ikigo gishinzwe guteranya PCB, PCB zikozwe mu kintu cyitwa substrate, gikozwe muri fiberglass ishyigikiwe na epoxy resin. Hejuru ya substrate hari urwego rwa foil y’umuringa rushobora gufatanywa ku mpande zombi cyangwa ku mpande imwe gusa. Iyo substrate imaze gukorwa, abakora bayishyiramo ibice. Bakoresha mask yo gusoda na silkscreen hamwe na resistor, capacitors, transistors, diodes, circuit chips, n’ibindi bice byabugenewe cyane.

Kuki ikoreshwa rya foil y'umuringa muri PCB?

Abakora PCB bakoresha umuringa kuko ufite ubushobozi bwo gutwara amashanyarazi n'ubushyuhe bwinshi. Uko umuriro w'amashanyarazi ugenda ujyana na PCB, umuringa urinda ubushyuhe kwangiza no gukomeretsa igice gisigaye cya PCB. Hamwe n'izindi alloys - nka aluminiyumu cyangwa icyuma - PCB ishobora gushyuha idahuje kandi ntikore neza.

Umuringa ni wo ukoreshwa cyane kuko ushobora kohereza ibimenyetso by'amashanyarazi ku rubuga nta kibazo cyo gutakaza cyangwa kugabanya umuvuduko w'amashanyarazi. Ubuhanga bwo kohereza ubushyuhe butuma abakora ibikoresho bashobora gushyiraho utumashini dushyushya twa kera hejuru y'ubutaka. Umuringa ubwawo urakora neza, kuko agace gato k'umuringa gashobora gutwikira metero kare ya PCB ku bunini bwa santimetero 1.4 cyangwa mikorometero 35.

Umuringa uyobora cyane kuko ufite electron yigenga ishobora kuva kuri atome imwe ijya ku yindi idatinze. Kubera ko ikomeza gukora neza kuri urwo rwego rworoshye cyane nk'uko ikora ku rwego rwo hejuru, umuringa muto ugira akamaro kanini.

Umuringa n'ibindi byuma by'agaciro bikoreshwa mu bikoresho bya PCB
Abantu benshi bemera ko PCB ari icyatsi kibisi. Ariko, akenshi ziba zifite amabara atatu ku gice cyo hanze: zahabu, ifeza, n'umutuku. Zifite kandi umuringa mwiza imbere no hanze ya PCB. Ibindi byuma biri ku rubuga rw'amashanyarazi bigaragara mu mabara atandukanye. Igice cya zahabu ni cyo gihenze cyane, igice cya feza ni cyo cya kabiri gihenze cyane, naho igitukura ni cyo gihenze cyane.

Gukoresha zahabu yo kwibira mu bikoresho bya PCB
umuringa ku kibaho cy'uruziga cyacapwe

Urupapuro rwa zahabu rukoreshwa mu gukata uduce duhuza uduce n'uduce tw'ibice. Urupapuro rwa zahabu rukoreshwa mu gukumira kwimuka kw'atomu zo hejuru. Urupapuro si zahabu gusa, ahubwo rukozwe muri zahabu nyayo. Zahabu ni nto cyane ariko irahagije kugira ngo yongere igihe cyo kubaho cy'ibice bigomba gushongeshwa. Zahabu irinda ibice bya solder kwangirika uko igihe kigenda.

Gukoresha ifeza yo kwibiza mu bikoresho bya PCB
Ifeza ni ikindi cyuma gikoreshwa mu gukora PCB. Ihendutse cyane ugereranyije no kwibiza zahabu. Kwibiza zahabu bishobora gukoreshwa mu mwanya wo kwibiza zahabu kuko binafasha mu guhuza, kandi bigabanya ikiguzi rusange cy'urubaho. Kwibiza amafaranga akenshi bikoreshwa muri PCB zikoreshwa mu modoka no mu bikoresho bya mudasobwa.

Laminate y'umuringa ikozwe muri PCB
Aho gukoresha icyuma cyo kwibiza mu mazi, umuringa ukoreshwa mu buryo bupfutse. Uru ni urwego rutukura rwa PCB, kandi ni cyo cyuma gikoreshwa cyane. PCB ikozwe mu muringa nk'icyuma cy'ibanze, kandi ni ngombwa kugira ngo imiyoboro ihuze kandi ivugane neza.

Ni gute Copper Foil ikoreshwa muri PCB?

Umuringa ukoreshwa mu buryo butandukanye muri PCB, kuva kuri laminate ipfutse umuringa kugeza ku duce duto. Umuringa ni ingenzi cyane kugira ngo PCB zikore neza.

PCB Trace ni iki?
Uburyo bwo kumvikana bwa PCB ni bwo buryo bwumvikana, inzira uruziga rukurikira. Uburyo bwo kumvikana burimo urusobe rw'umuringa, insinga, n'ubushyuhe, ndetse na fuse n'ibice bikoreshwa ku kibaho.

Uburyo bworoshye bwo gusobanukirwa ikimenyetso ni ukugitekereza nk'umuhanda cyangwa ikiraro. Kugira ngo imodoka zigere ku modoka, ikimenyetso kigomba kuba kinini bihagije kugira ngo kibe cyakira nibura bibiri muri byo. Kigomba kuba kinini bihagije kugira ngo kidasenyuka bitewe n'umuvuduko. Kigomba kandi gukorwa mu bikoresho bihangana n'uburemere bw'imodoka zigendamo. Ariko, ibimenyetso byose bikora ibi ku rugero ruto cyane kugira ngo bitware amashanyarazi aho gutwara imodoka.

Ibice bigize PCB Trace
Hari ibice byinshi bigize ikimenyetso cya PCB. Bifite imirimo itandukanye igomba gukorwa kugira ngo ikibaho gikore akazi kacyo neza. Umuringa ugomba gukoreshwa kugira ngo ufashe ibimenyetso gukora imirimo yabyo, kandi iyo PCB itagira, nta bikoresho by'amashanyarazi twari kugira. Tekereza isi idafite telefoni zigendanwa, mudasobwa zigendanwa, imashini zikora ikawa, n'imodoka. Ibyo nibyo twari kugira iyo PCB zidakoresha umuringa.

Ubunini bwa PCB Trace
Igishushanyo cya PCB giterwa n'ubugari bw'ikibaho. Ubunini buzagira ingaruka ku buringanire kandi bugatuma ibice biguma bihujwe.

Ubugari bwa PCB Trace
Ubugari bw'ikimenyetso nabwo ni ingenzi. Ibi ntibigira ingaruka ku buringanire cyangwa ku gufatanya kw'ibice, ariko bituma umuriro ukomeza kwimuka nta gushyuha cyane cyangwa kwangiza ikibaho.

Umuyoboro wa PCB Trace
Umuyoboro wa PCB ni ngombwa kuko ari wo ikibaho gikoresha mu gutwara amashanyarazi binyuze mu bice n'insinga. Umuringa ufasha ibi kubaho, kandi electron yigenga kuri buri atome ituma umuriro ugenda neza hejuru y'ikibaho.

Kuki Copper Foil iri kuri PCBs

Uburyo bwo gukora PCB
Uburyo bwo gukora PCB ni bumwe. Hari ibigo bimwe bibikora vuba kurusha ibindi, ariko byose bikoresha uburyo n'ibikoresho bimwe. Izi ni intambwe:

Kora fondasiyo ukoresheje fiberglass na resin
Shyira inkingi z'umuringa ku rufatiro
Kumenya no gushyiraho imiterere y'umuringa
Oza ikibaho mu bwogero
Shyiramo agapfukamunwa gakingira PCB kugira ngo urinde PCB
Shyira agakoresho k'ubudodo kuri PCB
Shyira kandi ushodeshe resistor, imiyoboro ihuriweho, capacitors, n'ibindi bice
Gerageza PCB

PCB zigomba kugira ibice byihariye cyane kugira ngo zikore neza. Kimwe mu bintu by'ingenzi bya PCB ni umuringa. Iyi alloy ikenewe kugira ngo ijyane amashanyarazi ku bikoresho PCB zizashyirwamo. Iyo umuringa udafite, ibikoresho ntibizakora kuko amashanyarazi adafite alloy yo kunyuramo.
