Kwirinda umwobo muguhitamo no gusudira bikubiyemo kwipimisha inzira nshya yo gukora no gusesengura ibisubizo. Guhitamo no gusudira hasudira akenshi bitera kumenyekana, nkubwoko bwumusirikare paste cyangwa drill bikinishwa muburyo bwo gukora. Abakora ibicuruzwa barashobora gukoresha ingamba zingenzi zo kumenya no gukemura impamvu zisanzwe zitera.

1.Gukurikirana ubushyuhe bwa reflux

Bumwe mu buryo bwo gukumira imyuka yo gusudira nuguhindura agace kanini k'umurongo wa reflux. Gutanga ibihe bitandukanye birashobora kwiyongera cyangwa kugabanya amahirwe yo kuzura. Gusobanukirwa neza kugaruka kugaruka ni ngombwa mugukumira ibyatsi byiza.

Ubwa mbere, reba igenamiterere rya none mugihe cyo gushyuha. Gerageza kongera ubushyuhe (kwagura igihe cyo guhindura imirongo. Imyobo yagurishijwe irashobora gushinga kubera ubushyuhe budahagije muri zone ibaho, bityo bagakoresha izi ngamba kugirango bakemure intandaro.

Ahantu h'ubushyuhe bushingiye kuri hamwe nabyo birasanzwe kandi abanyabyaha mu mutima usudira. Ibihe bigufi ntibishobora kwemerera ibice byose hamwe ninzego zubuyobozi kugera kubushyuhe bukenewe. Gerageza kwemerera igihe cyinyongera kuriyi gice cyumurongo wa reflux.

2.USE SHOX

Flux cyane irashobora kongera kandi mubisanzwe biganisha ku gusudira. Ikindi kibazo hamwe nu mwobo uhuriweho: Slux Swessing. Niba flux idafite umwanya uhagije wo guhagarikwa, gaze irenze izafatwa kandi idafite icyuho.

Iyo flux cyane ikoreshwa kuri PCB, igihe gisabwa kugirango flux itunganijwe rwose iragunze. Keretse niba wongeyeho igihe cyangiritse, flux yinyongera izavamo indabyo.

Mugihe wongeyeho igihe cyatuje gishobora gukemura iki kibazo, nibyiza gukomera kumashanyarazi asabwa. Ibi bizigama imbaraga nubutunzi kandi bigatuma ihuriro ryinshi.

3.Koresha imyitozo ityaye gusa

Impamvu rusange yo gushushanya ni umukene binyuze mu gucukura umwobo. Ibiti byijimye cyangwa ubukene buke birashobora kongera amahirwe yo kwishyiriraho imyanda mugihe cyo gucukura. Iyo ibyo bice byimye kuri PCB, bashiraho ahantu hashobora gushyirwaho umuringa. Iyi ituzo ryibikorwa, ubuziranenge no kwizerwa.

Abakora barashobora gukemura iki kibazo bakoresheje imyitozo ityaye kandi ityaye. Shiraho gahunda ihamye yo gukaraba cyangwa gusimbuza imboga bits, nka buri gihembwe. Uku kubungabunga buri gihe bizemeza ko bihuje ubuziranenge bushingiye ku buhanga no kugabanya ibishoboka ku myanda.

4.Ibishushanyo mbonera bitandukanye

Igishushanyo mbonera gikoreshwa muburyo bwuzuye birashobora kugufasha gukumira indwara nziza. Kubwamahirwe, ntamuntu numwe-ufite ubunini - igisubizo cyose kubishushanyo mbonera byo guhitamo. Ibishushanyo bimwe bikora neza hamwe numucuruzi utandukanye paste, flux, cyangwa ubwoko bwa PCB. Irashobora gufata ibigeragezo no kwibeshya kugirango ubone amahitamo yubwoko runaka.

Kubona neza igishushanyo mbonera cyanditse bisaba inzira nziza yo kugerageza. Abakora bagomba gushaka uburyo bwo gupima no gusesengura ingaruka zigishushanyo mbonera ku bupfu.

Inzira yizewe yo gukora ibi nugukora icyiciro cya PCB hamwe nigishushanyo cyihariye cyo gushushanya hanyuma ubigenzure neza. Inyandikorugero zitandukanye zikoreshwa mugukora ibi. Ubugenzuzi bugomba guhishura ibishushanyo mbonera bifite impuzandengo yumwobo wa abacuruzi.

Igikoresho cyingenzi muburyo bwo kugenzura ni imashini ya x-ray. X-Imirasire ni bumwe mu buryo bwo kubona indagihe kandi ni ingirakamaro cyane mugihe ukorana na mato mato, yuzuye cyane. Kugira imashini yoroshye x-ray izakora inzira yo kugenzura byoroshye kandi neza.

5.Gukoresha imiyoboro

Usibye gukaza imbere gato, umuvuduko wo gucukura nawo uzagira ingaruka zikomeye ku bwiza. Niba umuvuduko muto uri hejuru cyane, bizagabanya ukuri no kongera amahirwe yo kwihitiramo imyanda. Umuvuduko mwinshi wo gucukura urashobora no kongera ibyago byo gusenyuka kwa PCB, ubangamira ubunyangamugayo.

Niba umwobo uri mu ipfundo uracyari rusange nyuma yo gukangura cyangwa guhindura bike, gerageza kugabanya igipimo cyo gucukura. Umuvuduko utinda wemerera igihe kinini cyo gukora, gusukura binyuze mu mwobo.

Wibuke ko uburyo gakondo bwo gukora ntabwo aribwo buryo bwo guhitamo. Niba imikorere isuzumwa mugutwara ibiciro byo gucumura hejuru, 3d Gucapa birashobora guhitamo neza. 3D yacapwe PCB ikozwe neza kuruta uburyo gakondo, ariko hamwe na kimwe cyangwa hejuru. Guhitamo 3D byacapwe PCB ntibishobora gusaba gucukura ukoresheje umwobo rwose.

6.Sstick to Umugurisha Uhemutse Paste

Ni ibisanzwe gushakisha uburyo bwo kuzigama amafaranga mubikorwa bya PCB. Kubwamahirwe, kugura paste uhendutse cyangwa bike-byiza umusirikare ashobora kongera amahirwe yo gukora imbonankubone.

Imitungo minini yubwoko butandukanye bwa paste igira ingaruka kumikorere yabo nuburyo bakorana na PCB mugihe cya reflux. Kurugero, ukoresheje paste yumusirikare itarimo iyambere irashobora kugabanuka mugihe cyo gukonjesha.

Guhitamo umusirikare mwiza usaba kumva ukeneye ibikenewe bya PCB na Inyandikorugero. Paste umusirikare ya paste azagorana kwipimisha inyandikorugero hamwe na aperture nto.

Birashobora kuba ingirakamaro yo kugerageza umucuruzi utandukanye icyarimwe nkuko bigerageza inyandikorugero zitandukanye. Hashimangiweho ukoresheje itegeko rya gatanu kugirango uhindure icyitegererezo cyintoki kugirango umucuruzi paste ahuye nibisobanuro. Amategeko avuga ko abakora bakoresha imirimo hamwe na aperture basabwa guhuza imipira itanu yaka. Iki gitekerezo cyoroshya inzira yo gukora inyandiko y'ibishushanyo mbonera bya paste yo kwipimisha.

7.Umusirikare umusirikare paste okiside

Okidation yumucuruzi Paste ibaho mugihe hari umwuka mwinshi cyangwa ubuhehere mubikorwa byo gukora ibidukikije. Okiside ubwayo yongera amahirwe yo kutagira amabara, kandi yerekana ko umwuka urenze cyangwa ubuhemu wongeraho byoroshye ibyago byo kuvugiza. Gukemura no kugabanya ibimama bifasha gukumira indahiro gukora no kunoza ubuziranenge bwa PCB.

Banza ugenzure ubwoko bwumucuruzi paste yakoreshejwe. Umusirikare-Gukuramo Amazi Paste akunda kuri okiside. Mubyongeyeho, flux idahagije yongera ibyago byo kunyeganyega. Nibyo, flux cyane nayo nikibazo, abakora rero bagomba kubona uburimbane. Ariko, niba okiside ibaye, yongera ingano ya flux irashobora gukemura ikibazo.

Abakora PCB barashobora gufata ingamba nyinshi zo kwirinda gushushanya no gusudira imyobo yibicuruzwa bya elegitoroniki. Amabara agira ingaruka kwizerwa, imikorere nubwiza. Kubwamahirwe, kugabanya amahirwe yo kuvoma ni byoroshye nko guhindura umugurisha paste cyangwa ukoresheje igishushanyo gishya.

Ukoresheje uburyo-Kugenzura-Gusesengura-Gusesengura, uruganda wese rushobora kubona no gukemura intandaro yumuzi uhindagurika no gushushanya.
