Ikibaho cya PCBamategeko n'uburyo
1. Ukurikije ibisabwa byinganda zinganda zitandukanye, ubunini ntarengwa nubunini bwikibaho bigomba kumvikana neza.Mubisanzwe, PCB ntoya ya 80X80mm igomba guhurizwa hamwe, kandi ingano ntarengwa biterwa nubushobozi bwo gutunganya uruganda.Muri make, ingano ya pcb igomba kuba yujuje ibisabwaIbikoresho bya SMTibikoresho, bifasha gutunganya SMT patch no gufasha guhitamo ubunini bwubuyobozi bwa PCB.
2. Inteko hamwe n-ibyicaro bigomba kuba byujuje ibisabwa na DFM na DFA, kandi mugihe kimwe kugirango inteko ya PCB ikosorwe kandi idahinduka byoroshye nyuma yo gushyirwa mubikorwa.Kugabanya ibice hagati yibibaho bigomba kuba byujuje ibisabwa hejuru yubuso mugihePCBAgutunganya chip.
3. Muburyo bwa PCBigishushanyo, gutondekanya ibice bigomba kwirinda gucamo ibice no gutera ibice.Gukoresha ibipapuro byabanjirije amanota birashobora kugabanya urupapuro rwintambara no guhindura ibintu mugihe cyo gutandukana, kandi bikagabanya imihangayiko kubigize.Nibura, gerageza kudashyira agaciroIbigizeubutahakuruhande rwibikorwa.
4. Ingano nuburyo bwikibaho bikemurwa ukurikije umushinga wihariye, kandi igishushanyo mbonera kigaragara hafi ya kare bishoboka.Birasabwa cyane gukoresha uburyo bwa 2 × 2 cyangwa 3 × 3.Ntabwo byemewe guhuza yin na yang paneli niba bidakenewe;
5. Iyo urucacagu rwumuhuza wurubaho rurenze kwivanga hagati yimbaho nyinshi, bikemurwa no kuzenguruka uruhande + rwibikorwa kugirango hirindwe ubuziranenge bw’ibyangiritse mugihe cyo kohereza cyangwa gutunganyanyuma yo gusudira.
6. Nyuma yo gushushanya ikibaho, hagomba kwemezwa ko inkombe yerekana aho ikibaho kinini iba byibuze byibuze 3.5mm uvuye ku nkombe yikibaho (intera ntoya ya mashini ifata inkombe ya PCB ni 3.5mm ), kandi ingingo ebyiri zerekana diagonal ku kibaho kinini ntizishobora gushyirwa hamwe.Ntugashyire ingingo yerekanwe muburyo bumwe, kugirango impande zinyuma / zinyuranye za PCB zishobore kwinjira mumashini binyuze mumikorere iranga igikoresho ubwacyo.
7. Iyo ubunini bwaUbuyobozi bwa PCBni munsi ya 1.0mm, imbaraga zumwanya wibibaho byose bizagabanuka cyane (gucika intege) mugihe hongeweho guteranya ingingo cyangwa v-gukata, kuko ubujyakuzimu bwa V bwaciwe ni 1/3 cyubugari bwibibaho, Hagati ya ikibaho cya PCB gikoreshwa mu mbaraga, kandi igice cya skeleton ishigikira - umwenda wa fibre fibre ya V wacitse, bikaviramo koroshya imbaraga.Niba idashyigikiwe na jig, bizagira ingaruka kubikorwa biri munsi ya PCBA.
8. Iyo bihariintoki za zahabukuri PCB, mubisanzwe shyira intoki za zahabu hanze yubuyobozi mu cyerekezo cyumwanya utagabanijwe.Impera y'urutoki rwa zahabu ntishobora guterwa cyangwa gutunganywa.
