Koresha 2-layer igoye PCB hamwe na mask yo kugurisha umutuku

Kora 2-layer igoye PCB hamwe na mask yo kugurisha umutuku Kugaragaza Ishusho

Ibisobanuro bigufi:

Ikibaho cyumuzingi cyibice bibiri cyane cyane kugirango gikemure igishushanyo mbonera cyumuzenguruko hamwe nuburinganire bwagace, kumpande zombi zubuyobozi bwashyizweho ibice, ibyuma bibiri cyangwa ibyuma byinshi. , ibyongerera imbaraga, sisitemu yo kumurika, hamwe nimbaho yimodoka. PCBs zibiri ninziza kubikorwa byubuhanga buhanitse, imiyoboro ya elegitoroniki yoroheje, hamwe nizunguruka zikomeye. Porogaramu yayo ni nini cyane kandi igiciro ni gito.

Ibibazo

Ikibazo: PCB ni iki?

PCB-ibice 2 ni umuringa usizwe kumpande zombi hamwe na insuline hagati. Ifite ibice kumpande zombi zubuyobozi, niyo mpamvu nanone yitwa PCB-impande ebyiri. Bahimbwe muguhuza ibice bibiri byumuringa hamwe, hamwe nibikoresho bya dielectric hagati.

Ikibazo: ibice 2 PCB na 4 ibice PCB: itandukaniro irihe?

Urashobora kwerekana itandukaniro rigaragara riri hagati yibice 2 PCB na 4 PCB ukurikije amazina yabo. Ibice 2 PCB ifite ibimenyetso bibiri byuruhande hamwe hejuru no hepfo, mugihe ibice 4 PCB ifite ibice 4. Niba ufite gusobanukirwa neza ubwoko bubiri bwibibaho bya PCB, uzasanga hari itandukaniro ryinshi muburyo bwubatswe nuburyo bwo gukora.

Ikibazo: Uruhande rumwe & Impande ebyiri PCBs - Ni irihe tandukaniro?

Inzira imwe ya PCB iraboneka kuruhande rumwe gusa, mugihe impande zombi PCB zifite ibimenyetso kumpande zombi hamwe hejuru no hepfo. Ibigize hamwe nu muringa uyobora byashyizwe kumpande zombi za PCB impande zombi, kandi ibyo biganisha ku ihuriro cyangwa guhuzagurika.

Ikibazo: Nshobora kubona prototype yubusa ya 2 layer board?

Nibyo, twohereze gusa dosiye yawe ya gerber.

Ikibazo: Niki gihe gisanzwe cyo kuyobora gahunda ya prototype?

3WDS.

UwitekaPCB 2(impande zombi PCB) ni ikibaho cyumuzingo cyacapishijwe umuringa usize impande zombi, hejuru no hepfo. Hariho urwego rukingira hagati, arirwo rusanzwe rukoreshwa rwanditseho uruziga. Impande zombi zirashobora gutondekwa no kugurishwa, bigabanya cyane ingorane zimiterere, bityo ikoreshwa cyane.

Gukoresha imirongo kumpande zombi, hagomba kubaho imiyoboro ikwiye ihuza impande zombi. "Ikiraro" hagati yizunguruka zitwa vias. A kunyuramo ni umwobo muto ku kibaho cya PCB cyuzuye cyangwa usize icyuma, gishobora guhuzwa n'imirongo ku mpande zombi. Kuberako ubuso bwibibaho byimpande ebyiri burikubye kabiri ubw'ubutegetsi bumwe, ikibaho cyimpande zombi gikemura ingorane zubuyobozi bumwe kubera imiterere ihuza (irashobora guhuzwa kurundi ruhande; unyuze mu mwobo), kandi birakwiriye cyane kumirongo igoye kuruta ikibaho kimwe.

Dukeneye ibicuruzwa bya elegitoronike bifite imikorere ihanitse, ingano ntoya, hamwe nibikorwa byinshi, biteza imbere iterambere ryibicuruzwa byumuzunguruko byacapwe kugirango byorohe, byoroshye, bigufi, na bito. Hamwe n'umwanya muto, ibikorwa byinshi birashobora kugerwaho, ubwinshi bwimiterere bwabaye bunini, kandi umwobo wa diameter ni muto. Umwobo ntarengwa wa diameter yubushobozi bwo gucukura wagabanutse uva kuri 0.4mm ugera kuri 0.2mm cyangwa muto. Umwobo wa diameter ya PTH uragenda uba muto. Ubwiza bwa PTH (Yashizweho Binyuze mu mwobo) aho umurongo uhuza umurongo uhuza biterwa no kwizerwa kwicapiro ryumuzingo ryacapwe.
