Kubwimpamvu nyinshi, hariho ubwoko bwinshi bwimishinga yo gukora PCB isaba uburemere bwumuringa bwihariye.Twakira ibibazo byabakiriya batamenyereye igitekerezo cyuburemere bwumuringa burigihe, iyi ngingo rero igamije gukemura ibyo bibazo.Mubyongeyeho, ibikurikira bikubiyemo amakuru ajyanye ningaruka zuburemere butandukanye bwumuringa mugikorwa cyo guteranya PCB, kandi turizera ko aya makuru azagira akamaro no kubakiriya basanzwe bamenyereye icyo gitekerezo.Gusobanukirwa byimbitse kubikorwa byacu birashobora kugufasha gutegura neza gahunda yinganda nigiciro rusange.

Urashobora gutekereza kuburemere bwumuringa nkubunini cyangwa uburebure bwumuringa, nicyo gipimo cya gatatu imibare yumuringa ya dosiye ya Gerber idatekereza.Igice cyo gupima ni ounci kuri metero kare (oz / ft2), aho 1.0 oz y'umuringa ihindurwamo umubyimba wa mili 140 (35 mm).

Umuringa uremereye PCBs ukoreshwa mubikoresho bya elegitoroniki cyangwa ibikoresho byose bishobora guhura nibidukikije.Ibimenyetso byimbitse birashobora gutanga igihe kirekire, kandi birashobora kandi gutuma inzira yo gutwara ibintu byinshi bitarinze kongera uburebure cyangwa ubugari bwurwego kugeza kurwego rutumvikana.Ku rundi ruhande rwikigereranyo, uburemere bwumuringa bworoheje rimwe na rimwe bugaragazwa kugirango ugere ku mbogamizi zidasanzwe zidakenewe uburebure buto cyane cyangwa uburebure.Kubwibyo, mugihe ubara ubugari bwikurikiranwa, "uburemere bwumuringa" numurima ukenewe.

Ubusanzwe umuringa ufite uburemere ni 1.0 ounce.Byuzuye, bibereye imishinga myinshi.Muri iyi ngingo, bivuga gushira uburemere bwa mbere bwumuringa kugeza ku giciro cyo hejuru mugihe cyo gukora PCB.Mugihe ugaragaza uburemere bwumuringa busabwa mumakipe yacu yo kugurisha, nyamuneka werekane agaciro kanyuma (plaque) yuburemere bukenewe bwumuringa.

Umuringa mwinshi PCB ufatwa nka PCBs hamwe nuburebure bwumuringa wimbere ninyuma kuva kuri 3 oz / ft2 kugeza 10 oz / ft2.Uburemere bw'umuringa bw'umuringa uremereye PCB yabyaye kuva kuri ounci 4 kuri metero kare kugeza kuri 20 kuri metero kare.Uburemere bwumuringa bwongerewe imbaraga, bufatanije nu mubyimba mwinshi hamwe na substrate ikwiye mu mwobo, birashobora guhindura ikibaho cyumuzunguruko kidakomeye muburyo burebure kandi bwizewe.Imiyoboro iremereye y'umuringa izongera cyane umubyimba wa PCB yose.Ubunini bwumuringa bugomba guhora busuzumwa mugihe cyizunguruka.Ubushobozi bwo gutwara bugenwa nubugari nubunini bwumuringa uremereye.

Uburemere buringaniye bwumuringa ntabwo buzongera umuringa ubwabwo, ahubwo buzanatera uburemere bwubwikorezi nigihe gikenewe kumurimo, ubwubatsi butunganyirizwa, hamwe nubwishingizi bufite ireme, biganisha ku kongera ibiciro no kongera igihe cyo gutanga.Ubwa mbere, izi ngamba zinyongera zigomba gufatwa, kubera ko umuringa wongeyeho umuringa kuri laminate bisaba igihe kinini kandi ugomba kubahiriza amabwiriza yihariye ya DFM.Uburemere bwumuringa bwibibaho byumuzunguruko nabwo bugira ingaruka kumikorere yubushyuhe, bigatuma ikibaho cyumuzunguruko gikurura ubushyuhe vuba mugihe cyo kugurisha kugarura inteko ya PCB.

Nubwo nta gisobanuro gisanzwe cyumuringa uremereye, biremewe muri rusange ko niba intanga 3 (oz) cyangwa zirenga zumuringa zikoreshwa kumurongo wimbere ninyuma yikibaho cyacapwe, byitwa PCB ikomeye y'umuringa.Umuzunguruko uwo ariwo wose ufite umubyimba wumuringa urenga ounci 4 kuri metero kare (ft2) nawo ushyirwa mubikorwa nkumuringa uremereye PCB.Umuringa ukabije bisobanura 20 kugeza kuri 200 kuri metero kare.

Inyungu nyamukuru yibibaho byumuringa biremereye nubushobozi bwabo bwo kwihanganira guhura ningaruka zikabije, ubushyuhe bwinshi hamwe nubushyuhe bwumuriro, bishobora gusenya imbaho ​​zisanzwe zisanzwe mumasegonda make.Isahani iremereye y'umuringa ifite ubushobozi bwo gutwara ibintu byinshi, ituma ishobora guhuzwa na porogaramu mu bihe bibi, nk'ingabo zirwanira mu kirere n'ibicuruzwa byo mu kirere.Bimwe mubindi byiza byimbaho ​​zumuringa ziremereye zirimo:

Bitewe nuburemere bwinshi bwumuringa kumurongo umwe wumuzunguruko, ingano yibicuruzwa iroroshye
Umuringa uremereye ushyizwe mu mwobo unyura hejuru ya PCB kandi bigafasha guhererekanya ubushyuhe mumashanyarazi yo hanze
Impinduka zo mu kirere zifite ingufu nyinshi

Ikibaho kinini cyumuringa cyacapwe gishobora gukoreshwa mubikorwa byinshi, nka transformateur planar, gukwirakwiza ubushyuhe, gukwirakwiza ingufu nyinshi, guhindura amashanyarazi, nibindi. Gukenera imbaho ​​zikomeye zometseho umuringa muri mudasobwa, imodoka, igisirikare, no kugenzura inganda bikomeje kwiyongera.Ikibaho cyumuringa cyacapishijwe imbaho ​​nacyo gikoreshwa kuri:

Amashanyarazi
Kohereza amashanyarazi
Ibikoresho byo gusudira
Inganda zikora imodoka
Imirasire y'izuba, nibindi

Ukurikije ibishushanyo mbonera, igiciro cyumusaruro wumuringa uremereye PCB urenze uw'ibisanzwe PCB.Kubwibyo, uko igishushanyo kirenze, nigiciro cyinshi cyo gukora umuringa uremereye PCBs.
