Kuki umuringa wakoreshejwe mukora pcb?

Ibibaho byumuzunguruko nibice bikenewe byibikoresho by'amashanyarazi menshi. PCB yuyu munsi ifite ibice byinshi kuri bo: substrate, ibimenyetso, mask yumucuruzi, na silksien. Kimwe mubikoresho byingenzi kuri PCB ni umuringa, kandi hari impamvu nyinshi zituma umuringa ukoreshwa aho kubandi gato nka aluminium cyangwa tin.

PCBs ikozwe iki?

Byavuzwe na Sosiyete ikora PCB, PCBs ikozwe mubintu bita substrate, bikozwe muri fiberglass ishimangirwa na epoxy resin. Hejuru ya Substrate ni urwego rwumuringa ushobora guhuzwa kumpande zombi cyangwa imwe gusa. Iyo substrate imaze gukorwa, abayikora bashyira ibice kuri yo. Bakoresha mask yumucuruzi hamwe na silkscreen hamwe nabatuwe, ubushobozi, basenga, diodies, imirongo yumuzunguruko, nibindi bikoresho byihariye.

Kuki umuringa wakoreshejwe muri PCB?

Abakora PCB bakoresha umuringa kuko ifite amashanyarazi arenze amashanyarazi. Mugihe amashanyarazi arimo amashanyarazi hamwe na PCB, umuringa utuma ubushyuhe bwangiza kandi ashimangira ibisigaye bya PCB. Hamwe nibindi bikoresho - nka aluminium cyangwa amabati - PCB ishobora gushyuha nta nubwoho kandi ntabwo ikora neza.

Umuringa nicyo wahisemo kuko ushobora kohereza ibimenyetso by'amashanyarazi hakurya y'inama nta kibaho cyo gutakaza cyangwa gutinda amashanyarazi. Imikorere yubushyuhe yemerera abakora kwishyiriraho ubushyuhe bwa kera hejuru. Umuringa ubwawo, ukomoka ku muringa ushobora gutwikira ikirenge cya PCB ku giciro cya 1.4 cya kabiri cya santimetero imwe.

Umuringa aragenda cyane kuko afite ectron yubusa ishobora gutembera muri atome imwe kugeza ku wundi ntatinze. Kuberako bigumye neza kuri iyo nzego zidasanzwe nkuko bigenda mu rwego rwabyitse, umuringa muto ujya kure.

Umuringa nibindi bindi byuma bikoreshwa muri PCBS
Abantu benshi bamenya PCB nkicyatsi. Ariko, mubisanzwe bafite amabara atatu kumurongo wo hanze: zahabu, ifeza, n'umutuku. Bafite kandi umuringa wuzuye imbere no hanze ya PCB. Ibindi byicaramo ku kibaho cyumuzunguruko cyerekana mumabara atandukanye. Igice cya Zahabu nicyo gihenze cyane, urwego rwa feza rufite ikiguzi cya kabiri, kandi umutuku ni urwego ruhenze cyane.

Gukoresha zahabu ya PCBS
Umuringa ku kibaho cy'umuzunguruko

Igice cyagenwe cya zahabu gikoreshwa muguhuza shrapnel nibigize ibice. Igitangaza cya zahabu kibaho kugirango wirinde kwimurwa kwa atome. Igice ntabwo ari zahabu gusa, ahubwo gikozwe muri zahabu nyayo. Zahabu iraryoroshye ariko irahagije kugirango yongere ubuzima bwimiterere yibyo bigomba kubatwara. Zahabu irinda ibice byumucuruzi muri Coroding mugihe.

Gukoresha ifeza ya PCBS
Ifeza ni iyindi fer ikoreshwa mukora pcb. Birashimishije cyane kuruta kwibiza kwa zahabu. Kwibizwa kwa feza birashobora gukoreshwa mu mwanya wa zahabu kuko nayo ifasha hamwe no guhuza, kandi bigabanya igiciro rusange cyinama. Kwibiza kwa feza akenshi bikoreshwa muri PCB ikoreshwa mumodoka na peteroli ya mudasobwa.

Umuringa Clad Laminate muri PCB
Aho gukoresha kwibiza, umuringa ukoreshwa muburyo bwambaye. Ngiyo urwego rutukura rwa PCB, kandi ni icyuma gikunze gukoreshwa. PCB ikozwe kumuringa nkicyuma cyibanze, kandi ni ngombwa kubona imirongo yo guhuza no kuvugana neza.

Nigute umuringa wakoreshejwe muri PCB?

Umuringa ufite imikoreshereze myinshi muri PCB, uhereye kumurima wambaye umuringa uhemba kuri tras. Umuringa ningirakamaro kuri PCB kugirango ukore neza.

PCB ikurikirana iki?
Ibisobanuro bya PCB nibyo birumvikana, inzira yumuzenguruko ugomba gukurikiza. Ibisobanuro bikubiyemo urusobe rw'umuringa, insinga, no kwishinyagurira, kimwe no guswera n'ibigize bikoreshwa ku kibaho.

Inzira yoroshye yo gusobanukirwa ibimenyetso nugutekereza nkumuhanda cyangwa ikiraro. Kugira ngo hashingiwe ku modoka, inzira ikeneye kuba yagutse bihagije kugirango ifate byibuze bibiri muri byo. Ikeneye kuba umubyinshi bihagije kugirango atasenyuka mukibazo. Bakeneye kandi gukorerwa ibikoresho bizahangana nuburemere bwimodoka zigenda. Ariko, ibimenyetso bikora ibi byose kurwego ruto cyane kugirango rwimuke amashanyarazi aho kuba imodoka.

Ibice bya PCB
Hano hari ibice byinshi bigize PCB. Bafite imirimo itandukanye igomba gukorerwa Inama y'Ubutegetsi gukora akazi kayo bihagije. Umuringa ugomba gukoreshwa kugirango ufashe ibimenyetso akazi kabo, kandi udafite PCB, ntabwo twaba dufite ibikoresho byamashanyarazi. Tekereza isi idafite terefone, mudasobwa zigendanwa, abakora ikawa, n'imodoka. Nibyo twaba dushaka niba PCB idakoresheje umuringa.

PCB THER
Igishushanyo cya PCB giterwa nubunini bwinama. Ubunini buzagira ingaruka ku buringanire kandi buzakomeza ibice bihujwe.

Ubugari bwa PCB
Ubugari bw'imyandikire nabwo ni ngombwa. Ibi ntabwo bihindura impirimbanyi cyangwa umugereka wibigize, ariko bikomeza kwimura ikiriho utaruye cyangwa wangiza ikibaho.

PCB Trace Ubu
Ibimenyetso bya PCB birakenewe kuko aribyo Ubuyobozi bukoreshwa bwo kwimura amashanyarazi binyuze mubice hamwe ninsinga. Umuringa ufasha ibi, kandi electron yubusa kuri buri atom abona igenda neza hejuru yinama.

Kuki umuringa wa file kuri PCB

Inzira yo gukora PCB
Inzira yo gukora PCB nimwe. Ibigo bimwe nibikora byihuse kurusha abandi, ariko bose bakoresha muburyo bumwe nibikoresho. Izi ni intambwe:

Kora urufatiro kuri fiberglass no kurenga
Shira ibiceri byinama kuri fondasiyo
Menya kandi ushireho imiterere yumuringa
Koza inama yo kwiyuhagira
Ongeraho mask yumugurisha kugirango urinde PCB
Shyira muri silksien kuri PCB
Ahantu n'umucuruzi abatuye, imizunguruko ihuriweho, ubushobozi, nibindi bikoresho
Gerageza PCB

PCB igomba kugira ibice byihariye byo gukora neza. Kimwe mubintu byingenzi bya PCB numuringa. Ibi bisobanuro birakenewe kugirango dukore amashanyarazi kubikoresho PCB izashyirwaho. Hatagira umuringa, ibikoresho ntibizakora kuko amashanyarazi atazagira amubuyoko kunyuramo.
