Hitamo uburyo bwinshi bwanditse bwumuzunguruko

Mugushushanya imbaho ​​nyinshi zacapwe zumuzunguruko (PCBs), guhitamo uburyo bukwiye bwo gutondeka ni ngombwa. Ukurikije igishushanyo mbonera, uburyo butandukanye bwo gutondekanya, nka enclave stacking hamwe na stacking simmetric stacking, bifite ibyiza byihariye.Muri iyi nyandiko ya blog, tuzareba uburyo bwo guhitamo uburyo bwiza bwo gutondeka, tuzirikana ibintu nkuburinganire bwibimenyetso, gukwirakwiza ingufu, no koroshya inganda.

Sobanukirwa nuburyo bwinshi bwo gutondekanya PCB

PCBs nyinshi igizwe nibice byinshi byibikoresho bitwara bitandukanijwe no kubika ibice. Umubare wibice muri PCB biterwa nuburyo bugoye bwo gushushanya nibisabwa byumuzunguruko. Uburyo bwo gutondeka bugena uburyo ibice bitunganijwe kandi bigahuzwa. Reka turebe neza uburyo butandukanye bwo gutondeka bukunze gukoreshwa mubishushanyo mbonera bya PCB.

1. Gushyira hamwe

Enclave stacking, izwi kandi nka matrix stacking, nuburyo bukunze gukoreshwa muburyo butandukanye bwa PCB. Iyi gahunda yo gutondekanya ikubiyemo guteranya ibice byihariye hamwe kugirango habeho agace kegeranye muri PCB. Gutondekanya enclave bigabanya inzira ihuza amatsinda atandukanye, bikavamo ubuziranenge bwibimenyetso. Yoroshya kandi gukwirakwiza amashanyarazi (PDN) igishushanyo mbonera kuko imbaraga nindege zubutaka birashobora guhuzwa byoroshye.

Nyamara, gutondekanya enlave nabyo bizana ibibazo, nkikibazo cyo gukurikirana inzira hagati yinzira zitandukanye. Hagomba kwitabwaho neza kugirango inzira zerekana ibimenyetso zidahungabanywa nimbibi zinyuranye. Byongeye kandi, enlave stacking irashobora gusaba uburyo bukomeye bwo gukora, byongera ibiciro byumusaruro.

2. Gutondekanya ibimenyetso

Symmetric stacking nubundi buryo busanzwe muburyo bwa PCB. Harimo gahunda yo guhuza ibice bikikije indege yo hagati, mubisanzwe bigizwe nimbaraga nindege. Iyi gahunda itanga no gukwirakwiza ibimenyetso nimbaraga muri PCB yose, kugabanya kugoreka ibimenyetso no kunoza ubuziranenge bwibimenyetso.

Gushyira hamwe bitanga inyungu nko koroshya inganda no gukwirakwiza ubushyuhe bwiza. Irashobora koroshya uburyo bwo gukora PCB no kugabanya ibibaho byumuriro, cyane cyane mubisabwa imbaraga nyinshi. Ariko, gutondekanya neza ntibishobora kuba bibereye kubishushanyo mbonera bisabwa byangiritse cyangwa gushyira ibice bisaba imiterere idasanzwe.

Hitamo uburyo bwiza bwo gutondeka

Guhitamo uburyo bukwiye bwo gutondekanya biterwa nibisabwa bitandukanye byubushakashatsi hamwe nubucuruzi. Dore ibintu bimwe na bimwe ugomba gusuzuma:

1. Ubunyangamugayo

Niba ubunyangamugayo bwibimenyetso ari ikintu gikomeye mubishushanyo byawe, gutondekanya enclave bishobora kuba amahitamo meza. Mugutandukanya amatsinda atandukanye yibice, bigabanya amahirwe yo kwivanga no kunyura. Kurundi ruhande, niba igishushanyo cyawe gisaba gukwirakwiza kuringaniza ibimenyetso, gutondekanya neza byerekana ibimenyetso byuzuye.

2. Gukwirakwiza ingufu

Reba imbaraga zo gukwirakwiza imbaraga zishusho yawe. Enclave stacking yoroshya imiyoboro yo gukwirakwiza amashanyarazi kuko ingufu nindege zubutaka birashobora guhuzwa byoroshye. Kurundi ruhande, gutanga amashanyarazi aringaniye, kugabanya ingufu za voltage no kugabanya ibibazo bijyanye nimbaraga.

3. Gukora ingamba zo kwirinda

Suzuma ibibazo byo gukora bijyanye nuburyo butandukanye bwo gutondeka. Gutondekanya enclave birashobora gusaba uburyo bukomeye bwo gukora bitewe no gukenera inzira ya kabili hagati ya enclave. Gutondekanya ibimenyetso biringaniye kandi byoroshye gukora, bishobora koroshya inzira yo gukora no kugabanya ibiciro byumusaruro.

4. Inzitizi zihariye zo gushushanya

Ibishushanyo bimwe bishobora kuba bifite aho bigarukira bituma uburyo bumwe bwo gutondeka bukundwa nubundi. Kurugero, niba igishushanyo cyawe gisaba kugenzura impedance yihariye cyangwa gushyira ibice bitamenyerewe, gutondekanya enlave birashobora kuba byiza.

ibitekerezo byanyuma

Guhitamo uburyo bukwiye bwa PCB uburyo bwo gutondeka ni intambwe yingenzi mubikorwa byo gushushanya. Mugihe ufata umwanzuro hagati ya stack stacking hamwe nuburinganire bwa tekinike, tekereza kubintu nkuburinganire bwibimenyetso, gukwirakwiza ingufu, no koroshya inganda. Mugusobanukirwa imbaraga nimbibi za buri nzira, urashobora guhindura igishushanyo cyawe kugirango uhuze ibisabwa neza.
