1. Umwanya uri hagati

Umwanya uri hagati ya SMD nikibazo abajenjeri bagomba kwitondera mugihe cyimiterere.Niba intera ari nto cyane, biragoye cyane gucapa paste yo kugurisha no kwirinda kugurisha no gutobora.

Ibyifuzo byintera nibi bikurikira

Ibikoresho bisabwa hagati yibi bikoresho:
Ubwoko bumwe bwibikoresho: ≥0.3mm
Ibikoresho bidasa: ≥0.13 * h + 0.3mm (h nuburebure ntarengwa bwo gutandukanya ibice bituranye)
Intera iri hagati yibigize bishobora guterwa intoki gusa: .51.5mm.

Ibyifuzo byavuzwe haruguru nibyerekanwe gusa, kandi birashobora gukurikiza gahunda ya PCB yuburyo bwihariye bwibigo.

2. Intera iri hagati yumurongo wumurongo na patch

Hagomba kubaho intera ihagije hagati yumurongo wigikoresho cyo kurwanya umurongo, kandi birasabwa kuba hagati ya 1-3mm.Bitewe no gutunganya ibibazo, ikoreshwa rya plug-ins igororotse ni gake ubu.

3. Kubijyanye no gushyira ubushobozi bwa IC decoupling capacator

Umuyoboro wa decoupling ugomba gushyirwa hafi yicyambu cya buri IC, kandi ikibanza kigomba kuba hafi hashoboka ku cyambu cy’amashanyarazi cya IC.Iyo chip ifite ibyambu byinshi byamashanyarazi, capacitor ikuramo igomba gushyirwa kuri buri cyambu.

4. Witondere icyerekezo cyo gushyira hamwe nintera yibigize kuruhande rwubuyobozi bwa PCB.

Kubera ko muri rusange PCB ikozwe muri jigsaw, ibikoresho hafi yinkombe bigomba kuba byujuje ibintu bibiri.

Iya mbere ni ukugereranya nicyerekezo cyo guca (kugirango ukore stress ya mashini yikintu kimwe. Kurugero, niba igikoresho gishyizwe munzira kuruhande rwibumoso bwishusho hejuru, imbaraga zinyuranye zerekezo za padi ebyiri za ibishishwa birashobora gutuma ibice hamwe no gusudira bigabanywa)
Iya kabiri ni uko ibice bidashobora gutondekwa mumwanya runaka (kugirango wirinde kwangirika kw ibice mugihe ikibaho cyaciwe)

5. Witondere ibihe aho udupapuro twegeranye dukeneye guhuzwa

Niba udupapuro twegeranye dukeneye guhuzwa, banza wemeze ko ihuza ryakozwe hanze kugirango wirinde ikiraro cyatewe nihuza, kandi witondere ubugari bwumugozi wumuringa muriki gihe.

6. Niba padi iguye ahantu hasanzwe, hagomba gutekerezwa gukwirakwiza ubushyuhe

Niba padi iguye kumwanya wa kaburimbo, inzira nziza igomba gukoreshwa muguhuza padi na kaburimbo.Kandi, menya niba uhuza umurongo 1 cyangwa imirongo 4 ukurikije ikigezweho.

Niba uburyo bwibumoso bwakoreshejwe, biragoye cyane gusudira cyangwa gusana no gusenya ibice, kuko ubushyuhe bwatatanye rwose numuringa washyizweho, bigatuma gusudira bidashoboka.

7. Niba isonga ari ntoya kuruta gucomeka, birasabwa amarira

Niba insinga ari ntoya kuruta padi yumurongo wumurongo, ugomba kongeramo amarira nkuko bigaragara kuruhande rwiburyo bwishusho.

Ongeraho amarira afite inyungu zikurikira:
.
(2) Ikibazo ko guhuza padi na tronc byacitse byoroshye kubera ingaruka byakemutse.
(3) Gushiraho amarira birashobora kandi gutuma ikibaho cyumuzunguruko cya PCB gisa neza.
