Nkumushinga wibyuma, akazi nugutezimbere PCB mugihe no muri bije, kandi bakeneye gukora mubisanzwe! Muri iki kiganiro, nzasobanura uburyo bwo gusuzuma ibibazo byinganda zubuyobozi bwumuzunguruko mugushushanya, kugirango ibiciro byubuyobozi bwumuzunguruko bigabanuke bitagize ingaruka kumikorere. Nyamuneka uzirikane ko tekinike nyinshi zikurikira zishobora kutuzuza ibyo ukeneye, ariko niba ibintu bibyemereye, nuburyo bwiza bwo kugabanya ibiciro.
Komeza ibice byose byubuso (SMT) kuruhande rumwe rwibibaho
Niba hari umwanya uhagije uhari, ibice byose bya SMT birashobora gushyirwa kuruhande rumwe rwumuzunguruko. Muri ubu buryo, ikibaho cyumuzunguruko gikeneye kunyura mubikorwa bya SMT rimwe gusa. Niba hari ibice kumpande zombi zumuzunguruko, bigomba kunyura kabiri. Mugukuraho SMT ya kabiri ikora, igihe cyo gukora nigiciro birashobora kuzigama.
Hitamo ibice byoroshye gusimbuza
Mugihe uhitamo ibice, hitamo ibice byoroshye gusimbuza. Nubwo ibi bitazigama ikiguzi icyo aricyo cyose cyo gukora, kabone niyo ibice byasimbuwe bidahari, nta mpamvu yo kongera gushushanya no guhindura ikibaho cyumuzunguruko. Nkuko abajenjeri benshi babizi, ni inyungu za buri wese kwirinda gushushanya!
Hano hari inama zo guhitamo ibice byoroshye gusimburwa:
Hitamo ibice bifite ibipimo bisanzwe kugirango wirinde gukenera guhindura igishushanyo igihe cyose igice kibaye impitagihe. Niba ibicuruzwa bisimburwa bifite ikirenge kimwe, ukeneye gusimbuza igice gishya kugirango urangize!
Mbere yo guhitamo ibice, nyamuneka sura imbuga zimwe na zimwe zabakora kugirango urebe niba ibice byose byanditseho "bitagikoreshwa" cyangwa "ntibisabwa kubishushanyo mbonera."
Hitamo igice gifite ubunini bwa 0402 cyangwa bunini
Guhitamo ibice bito bizigama umwanya wubuyobozi, ariko ubu buryo bwo guhitamo bufite inenge. Birasaba igihe kinini nimbaraga zo gushyirwa no gushyirwaho neza. Ibi biganisha ku giciro cyo gukora cyane.
Ninkaho umurashi urasa umwambi ku ntego ifite ubugari bwa metero 10 kandi ushobora kuwukubita utarinze kwibanda cyane. Abarashi barashobora kurasa ubudahwema badatakaza umwanya n'imbaraga nyinshi. Ariko, niba intego yawe yagabanutse kugera kuri santimetero 6 gusa, noneho umurashi agomba kwibanda no kumara igihe runaka kugirango akubite intego neza. Kubwibyo, ibice bito kurenza 0402 bisaba igihe kinini nimbaraga zo kurangiza kwishyiriraho, bivuze ko ikiguzi kizaba kinini.
Sobanukirwa kandi ukurikize ibipimo byumusaruro
Kurikiza ibipimo byatanzwe nuwabikoze. Bizakomeza igiciro gito. Imishinga igoye isanzwe itwara amafaranga menshi yo gukora.
Mugihe utegura umushinga, ugomba kumenya ibi bikurikira:
Koresha igipande gisanzwe hamwe nibikoresho bisanzwe.
Gerageza gukoresha PCB ya 2-4.
Komeza byibuze intera / icyuho kiri hagati yumwanya usanzwe.
Irinde kongeramo ibisabwa bidasanzwe bishoboka.
