Igikorwa cyo gukora ibice 8 bya PCBs kirimo intambwe zingenzi zingenzi kugirango habeho umusaruro mwiza wibibaho byiza kandi byizewe.Kuva igishushanyo mbonera kugeza inteko yanyuma, buri ntambwe igira uruhare runini mugushikira imikorere, iramba kandi ikora neza PCB.
Ubwa mbere, intambwe yambere mubikorwa 8 byo gukora PCB ni igishushanyo mbonera.Ibi bikubiyemo gukora igishushanyo mbonera cyinama, kugena aho ibice bigizwe, no guhitamo inzira yerekana inzira. Iki cyiciro mubisanzwe gikoresha ibikoresho bya software byashushanyije nka Altium Designer cyangwa EagleCAD kugirango ikore imibare ya PCB.
Igishushanyo kirangiye, intambwe ikurikira ni uguhimba ikibaho cyumuzunguruko.Igikorwa cyo gukora gitangirana no guhitamo ibikoresho bya substrate bikwiye, mubisanzwe epoxy ya fiberglass-ishimangirwa, izwi nka FR-4. Ibi bikoresho bifite imbaraga zubukanishi hamwe nuburyo bwo kubika ibintu, bigatuma biba byiza mubikorwa bya PCB.
Igikorwa cyo gukora kirimo intambwe-ntambwe nyinshi, zirimo guterana, guhuza ibice no gucukura.Etching ikoreshwa mugukuraho umuringa urenze kuri substrate, hasigara ibimenyetso na padi inyuma. Guhuza ibice noneho bikorwa kugirango bikurikirane neza ibice bitandukanye bya PCB. Icyitonderwa ni ngombwa muri iyi ntambwe kugirango tumenye neza ko imbere n'inyuma byahujwe neza.
Gucukura ni iyindi ntambwe yingenzi mubikorwa 8 byo gukora PCB.Harimo gucukura umwobo utomoye muri PCB kugirango ushobore guhuza amashanyarazi hagati yinzego zitandukanye. Ibyo byobo, byitwa vias, birashobora kuzuzwa nibikoresho byayobora kugirango bitange amasano hagati yabyo, bityo bizamura imikorere nubwizerwe bwa PCB.
Nyuma yo gukora ibicuruzwa birangiye, intambwe ikurikiraho ni ugukoresha masike yo kugurisha hamwe no gucapa ecran kugirango bimenyekanishe.Mask ya Solder ni igicucu cyoroshye cya polymer yerekana amafoto akoreshwa mukurinda ibimenyetso byumuringa okiside no gukumira ibiraro byabagurisha mugihe cyo guterana. Ububiko bwa silike ya ecran, kurundi ruhande, itanga ibisobanuro byibigize, ibishushanyo mbonera, nandi makuru yibanze.
Nyuma yo gukoresha masike yo kugurisha no gucapura ecran, ikibaho cyumuzunguruko kizanyura munzira yiswe icapiro rya paste.Iyi ntambwe ikubiyemo gukoresha ikaramu kugirango ubike urwego ruto rwa paste kugurisha hejuru yubuyobozi bwumuzunguruko. Solder paste igizwe nicyuma kivanze nicyuma gishonga mugihe cyo kugurisha ibintu kugirango bigire umurongo ukomeye kandi wizewe wamashanyarazi hagati yibigize na PCB.
Nyuma yo gukoresha paste yuwagurishije, imashini itwara-yikora ikoreshwa mugushira ibice kuri PCB.Izi mashini zerekana neza ibice mubice byagenwe hashingiwe ku gishushanyo mbonera. Ibigize bifatirwa hamwe hamwe na paste yagurishijwe, bigakora imiyoboro yamashanyarazi nigihe gito.
Intambwe yanyuma mubikorwa 8 byo gukora PCB murwego rwo kugurisha.Inzira ikubiyemo kwerekera ikibaho cyose cyumuzunguruko kurwego rwubushyuhe bugenzurwa, gushonga paste yo kugurisha no guhuza burundu ibice kubibaho. Igicuruzwa cyo kugurisha cyerekana uburyo bukomeye kandi bwizewe bwamashanyarazi mugihe wirinze kwangirika kubice kubera ubushyuhe bwinshi.
Nyuma yo kugurisha ibicuruzwa birangiye, PCB irasuzumwa neza kandi ikageragezwa kugirango irebe imikorere yayo nubuziranenge.Kora ibizamini bitandukanye nko kugenzura amashusho, ibizamini byo gukomeza amashanyarazi, hamwe nibizamini bikora kugirango umenye inenge cyangwa ibibazo.
Muri make ,.Inzira 8 ya PCB yo gukoraikubiyemo urukurikirane rw'intambwe zikomeye zikenewe mugutanga ikibaho cyizewe kandi cyiza.Kuva mubishushanyo mbonera no gukora, guteranya no kugerageza, buri ntambwe igira uruhare mubwiza rusange n'imikorere ya PCB. Mugukurikiza izi ntambwe neza kandi hamwe no kwitondera amakuru arambuye, abayikora barashobora kubyara PCB nziza cyane yujuje ibyangombwa bisabwa.
