Kubigo byinshi bito n'ibiciriritse bikoresha ibikoresho bya elegitoroniki, gutunganya PCB gutunganya ibintu nibintu bisanzwe.Ariko muri rusange, inganda nyinshi ziva hanze ntizizagukorera byose, cyangwa ntizishobora gusimbuza abakiriya kunoza ibintu bimwe na bimwe, nk'ibicuruzwa n'ibicuruzwa bihuza n'imiterere, gushyira mu gaciro, guhuza ibice, n'ibindi.
Niba amasoko cyangwa injeniyeri yikigo bashobora gukora ibintu 8 bikurikira neza mbere yo kujugunya ibikenerwa nibikoresho byumusaruro muruganda rutunganya ibicuruzwa bya PCB, ibibazo byinshi byahuye nabyo mubyakozwe nyuma no kubyara birashobora kwirindwa.
1. Shakisha ingano nziza ya PCB kubishushanyo byawe
Kubikorwa bya PCB, ikibaho gito gisobanura igiciro gito, ariko igishushanyo gishobora gusaba ibice byinshi byimbere, bizamura ibiciro byawe.Ikibaho kinini kizoroha gushushanya kandi ntibisaba ibimenyetso byerekana ibimenyetso, ariko bizaba bihenze kubikora.Ubwa mbere, ugomba gutekereza uburyo bwo kubara ingano ikwiriye utabuze ibiranga.
2. Kugaragaza ingano yikigize
Gusohora PCB gutunganya patch.jpg
Kubice bya pasiporo, ubunini busanzwe bwa 0603 bushobora kuba amahitamo meza kubiciro buke, nabwo nubunini busanzwe kandi bifasha guterana kwa SMT.Ibikoresho 0603 nabyo biroroshye kwimuka na serivisi, kandi ntukabe inzitizi nkibikoresho bya ultra-miniature.
Mugihe Pinho ishobora gutunganya ibikoresho bifite ubunini bwa 01005, ntabwo abateranya bose bashobora kubikora, kandi ibice byo munsi ntabwo ari ngombwa.
3. Reba ibice bitagikoreshwa cyangwa bishya cyane
Ibice bitagikoreshwa biragaragara ko bitagikoreshwa, ntibizakubuza gukora PCBA, ariko bizaguma mubikorwa byo guterana.Uyu munsi, ariko, ibice bimwe biboneka gusa muri ultra-miniature wafer BGA cyangwa ingano ya QFN.Reba igishushanyo cya PCBA hanyuma urebe ko wasimbuye ibice byose bishaje nibindi bishya.
Indi nyandiko ni ukuzirikana MLCCs ukoresha, ubu irasaba kugura igihe kirekire.
Noneho duha abakiriya isesengura-BOM ireba imbere, twandikire kugirango umenye uburyo ishobora kugufasha kwirinda ingaruka no kugabanya ingengo yimari kurwego runini.
4. Reba ubundi buryo
Ibindi ni igitekerezo cyiza, cyane cyane niba usanzwe ukoresha ibice bimwe-bimwe.Isoko rimwe risobanura ko utakaza kugenzura ibiciro nigihe cyo gutanga, ubundi buryo buzagufasha kwirinda ibyo.
5. Ntiwibagirwe gukwirakwiza ubushyuhe mugihe ukora imbaho zicapye
Ibice binini cyane nibice bito cyane birashobora gutera ibibazo.Igice kinini gikora nkicyuma gishyuha kandi gishobora kwangiza igice gito.Ikintu kimwe kirashobora kubaho mugihe umwenda wumuringa wimbere urenze igice cya kabiri cyigice gito ariko ntakindi gice.
6. Menya neza ko umubare wigice hamwe nibimenyetso bya polarite byemewe
Menya neza ko bigaragara neza ibara rya silkscreen rijyana nigice, kandi ko ibimenyetso bya polarite bidasobanutse.Witondere byumwihariko ibice bya LED kuko ababikora rimwe na rimwe bahinduranya ibimenyetso bya polarite hagati ya anode na cathode.Kandi, shyira ibimenyetso kure ya vias cyangwa padi iyo ari yo yose.
7. Reba verisiyo ya dosiye
Hazabaho verisiyo nyinshi zagateganyo zishusho ya PCB cyangwa BOM, gusa menya neza ko abo utwoherereje guhimba PCB ari ubugororangingo bwa nyuma.
8. Niba ibice bimwe bizatangwa
Nyamuneka wemeze ko wanditseho kandi ugapakira neza, harimo ingano n'umubare uhwanye.Amakuru arambuye yatanzwe azafasha abayikora kurangiza guhimba no guteranya imbaho zumuzingo zacapwe vuba.
