Ngatitarisei pcb bhodhi dhizaini uye pcba
Ndinotenda kuti vanhu vazhinji vakadarofamiliarpamwe pcb bhodhi dhizaini uye anogona kazhinji kuzvinzwa muupenyu hwezuva nezuva, asi vangasaziva zvakawanda pamusoro PCBA uye kunyange kuvhiringa nayo akadhindwa redunhu mapuranga.Saka chii chinonzi pcb board design?PCBA yakashanduka sei?Yakasiyana sei nePCBA?Ngatinyatsoongororai.
*Nezve pcb bhodhi dhizaini*

Nemhaka yekuti yakagadzirwa nemagetsi ekudhindwa, inonzi "yakadhindwa" bhodhi redunhu.The pcb bhodhi chinhu chinokosha zvemagetsi chikamu mune zvemagetsi indasitiri, kutsigira zvemagetsi zvinoriumba, uye mutakuri kuti magetsi kubatana zvemagetsi zvinoriumba.Mabhodhi ePCB akashandiswa zvakanyanya mukugadzira nekugadzira zvigadzirwa zvemagetsi.Hunhu hwayo hwakasiyana hunogona kupfupikiswa sezvizvi:

1. Yakakwira wiring density, diki diki uye uremu huremu hunoenderana neiyo miniaturization yezvigadzirwa zvemagetsi.

2. Pamusana pekudzokorora uye kuwirirana kwemifananidzo, zvikanganiso zve wiring uye gungano zvakaderedzwa, uye nguva yekugadzirisa michina, kugadzirisa uye kuongorora kunoponeswa.

3. Zvinobatsira kugadzira michina uye otomatiki kugadzira, kuvandudza kugadzirwa kwevashandi, uye kuderedza mutengo wemidziyo yemagetsi.

4. Iyo yakagadzirwa inogona kuenzaniswa kuitira nyore kuchinjana.

*Nezve PCBA*

PCBA ndiyo chidimbu cheakadhindwa redunhu bhodhi + gungano, kureva kuti, PCBA ndiyo nzira yese yekubatanidza chikamu chepamusoro chebhodhi isina chinhu chebhodhi redunhu rakadhindwa uye dipping.

CHERECHEDZA: Surface mount uye die mount inzira dzese dzekubatanidza michina pane yakadhindwa redunhu bhodhi.Musiyano mukuru ndewekuti tekinoroji yepamusoro haidi maburi ekuchera mubhodhi redunhu rakadhindwa, mapini echikamu anoda kuiswa mumakomba ekuchera eDIP.

Surface Mount Technology (SMT) Surface Mount tekinoroji inonyanya kushandisa pikicha uye yekuisa muchina kuisa zvimwe zvidiki pabhodhi redunhu rakadhindwa.Maitiro ayo ekugadzira anosanganisira PCB chinzvimbo, solder paste kudhinda, yekuisa muchina kuisirwa, reflow oveni uye kuongorora kugadzira.

MaDIP ma”plug-ins”, kureva kuisa zvikamu pabhodhi redunhu rakadhindwa.Izvi zvikamu zvakakura muhukuru uye hazvina kukodzera kugadzika tekinoroji uye zvakabatanidzwa muchimiro cheplug-ins.Iwo makuru ekugadzira maitiro ndeaya: adhesive, plug-in, kuongorora, wave soldering, brashi plating uye kuongorora kugadzira.

*Misiyano pakati pePCBs nePCBAs*

Kubva pane sumo iri pamusoro, tinogona kuziva kuti PCBA kazhinji inoreva maitiro ekugadzirisa, uye inogona zvakare kunzwisiswa seyapera redunhu bhodhi.PCBA inogona kuverengerwa chete mushure memaitiro ese ari padhinda redunhu bhodhi apera.A rakadhindwa redunhu bhodhi ichinhu chakadhindwa redunhu bhodhi isina zvikamu pairi.
