Mu gutunganya pcba, uburyo buhebuje bwinama yumuzunguruko bugira ingaruka zikomeye kumikorere no kugaragara kwumuzunguruko. Kubwibyo, ni ngombwa cyane kugenzura ubuziranenge bwikibaho cya PCB.Ubuyobozi bw'umuzungurukoUbwiza buhebuje bufitanye isano rya bugufi nigishushanyo mbonera cyumuzunguruko, ibikoresho byo gutunganya, Ikoranabuhanga ryisumbuye nibindi bintu.
一, Igishushanyo cya PCB Umuzunguruko
1. Igishushanyo cya padi
. Niba padi ari nini cyane, umugurisha akwirakwira ahantu ni manini, kandi ingingo zamazi zashizweho ntizuzuye. Kurundi ruhande, amakimbirane yubuso bwimiyoboro yumuringa ya padi ntoya ni nto cyane, kandi ingingo zifatanije nintoki zidashidikanywaho. Icyuho gihuye hagati ya aperture kandi ibice biganisha cyane kandi biroroshye gutera abagurisha ibinyoma. Iyo apeture ari 0.05 - 0.2Mm nini kuruta iyambere na padi diameter ni 2 - 2.5 Aperture, ni ibintu byiza byo gusudira.
. Gabanya kugurisha ibinyoma no kubura kugurisha. Ibigize bito ntibigomba gushyirwaho nyuma yibice binini kugirango birinde ibice binini byo kwivanga numuryango bitemba no kuvugana nibikoresho bito, bikavamo kumeneka.
2, PCB Umuzunguruko ugenzura
Kugarura umugeri ufite ibisabwa byinshi muburyo bwo gufunga imbaho. Mubisanzwe, intambara isabwa kuba munsi ya 0.5mm. Niba biruta 0.5mm, bigomba gugorora. By'umwihariko, ubunini bw'ibibaho bimwe byacapwe bigera kuri 1.5mm, kandi ibyangombwa byabo by'intambara biri hejuru. Bitabaye ibyo, ubuziranenge busurwa ntibushobora kwemezwa. Ibibazo bikurikira bigomba kwishyurwa:
(1) Ububiko bwanditse neza hamwe nibigize kandi bigabanye igihe cyo kubika bishoboka. Mugihe cyo gusudira, umuringa hamwe nibigize biganisha ku buryo butagira umukungugu, amavuta, na oxides bifasha gushinga gushiraho amakuru yuburayi babishoboye. Kubwibyo, imbaho n'ibigize ibice bigomba kubikwa ahantu humye. , ahantu hasukuye, kandi bigabanya igihe cyo kubika bishoboka.
(2) Kubibaho byacapwe byashyizwe igihe kirekire, ubuso muri rusange bugomba gusukurwa. Ibi birashobora kunoza imyanda no kugabanya abagurisha ibinyoma no kwiyera. Kubice bigize ibice hamwe nurwego runaka rwimyanda yubusa, hejuru igomba kuvanwaho mbere. oxide.
二. Igenzura ryiza ryibikoresho
Mugurisha umuraba, ibikoresho nyamukuru bikoreshwa ni: flux n'umucuruzi.
1. Gusaba flux birashobora gukuraho oxide hejuru yubusurwe, irinde kongera gusohora umugurisha no gusudira mugihe cyo gusudira, kugabanya amakimbirane yo hejuru, kandi afasha kwimura ubushyuhe mu rubuga rwo gusudira. Flux igira uruhare runini mu kugenzura ubuziranenge.
2. Igenzura ryiza ryumucuruzi
Amabati-umusirikare akomeje kunyerera mubushyuhe bwo hejuru (250 ° C), bitera amabati yo kuyobora amabati mu nkono ya eutectike, bituma habaho amazi meza kandi bikagabanya ibintu bike byo kugurisha, imbaraga zubusa, hamwe nimbaraga zubusa. .
三, inzira yo gusudira
Ingaruka zo gusudira ibipimo kuri gusudira hejuru yubusa ni ibintu bitoroshye.
Hariho ingingo nyinshi zingenzi: 1. Kugenzura ubushyuhe. 2. Gusunika inzira nziza. 3. Umuhengeri muremure. 4. Ubushyuhe bwo gusudira.
Isulding ni inzira yingenzi yintambwe mubikorwa bya PCB byumuganda. Kugirango tumenye neza ubuziranenge bwinama yumuzunguruko, umuntu agomba kuba yari akwiriye uburyo bwo kugenzura ubuziranenge nubuhanga bwo gutangara.
