Ndinotenda kuti vanhu vazhinji havana kujairana nemazwi ane chekuita neindasitiri yemagetsi sePCB redunhu bhodhi uye SMT chip processing. Izvi zvinowanzonzwika muhupenyu hwezuva nezuva, asi vanhu vazhinji havazive zvakawanda nezvePCBA uye vanowanzo vhiringika nePCB. Saka chii chinonzi PCBA? Ndeupi musiyano uripo pakati pePCBA nePCB? Ngatizivei.

I- PCBA:
PCBA process: PCBA = yakadhindwa redunhu bhodhi musangano, kureva, isina chinhu PCB bhodhi inopfuura nepakati pese muitiro weSMT kurodha uye dip plug-in, iyo inonzi PCBA maitiro kwenguva pfupi.

II-PCB:
Yakadhindwa yedunhu bhodhi (PCB) chinhu chakakosha chemagetsi chikamu, tsigiro yezvikamu zvemagetsi uye mutakuri wekubatanidza magetsi emagetsi ezvikamu. Nemhaka yokuti yakagadzirwa nekudhinda kwemagetsi, inonzi “yakadhindwa” bhodhi redunhu.

Printed Circuit Board:
Chirungu chipfupiso chePCB (chakadhindwa chedunhu bhodhi) kana PWB (chakadhindwa waya bhodhi) chinowanzo shandiswa. Icho chikamu chakakosha chemagetsi, kutsigirwa kwezvikamu zvemagetsi uye mupi wekubatanidza kutenderera kwezvikamu zvemagetsi. Yechinyakare redunhu bhodhi rinotora nzira yekudhinda etchant kuita dunhu nekudhirowa, saka inonzi yakadhindwa redunhu bhodhi kana rakadhindwa redunhu bhodhi. Nekuda kwekuenderera mberi kweminiaturization uye kukwenenzvera kwezvigadzirwa zvemagetsi, parizvino, mazhinji edunhu mabhodhi anogadzirwa nekubatanidza etching resist (kudzvanya firimu kana kukoira) uye etching mushure mekuratidzwa nekusimudzira.
Mukupera kwema1990, apo akawanda-layer akadhindwa edunhu redunhu zvirongwa akaiswa pamberi, akawanda-layer akadhindwa redunhu bhodhi akaiswa zviri pamutemo kushanda kusvika zvino.

Kusiyana pakati pePCBA nePCB:
1. PCB haina zvikamu
2. PCBA inoreva kuti mushure mokunge mugadziri awana PCB sezvinhu zvakasvibiswa, zvigadzirwa zvemagetsi zvinodiwa pakugadzira uye kuungana paPCB board kuburikidza neSMT kana plug-in processing, yakadai seIC, resistor, capacitor, crystal oscillator, transformer nezvimwe. electronic components. Mushure mekupisa kwepamusoro-kupisa muvira reflow, iyo mechanical connection pakati pezvikamu nePCB board ichaumbwa, kuitira kuti igadzire PCBA.
Kubva pane sumo iri pamusoro, tinogona kuziva kuti PCBA kazhinji inoreva maitiro ekugadzirisa, ayo anogona zvakare kunzwisiswa seakapedzwa redunhu bhodhi, kureva kuti, PCBA inogona kuverengerwa chete mushure mekunge maitiro ePCB apera. PCB inoreva chinhu chisina chinhu yakadhindwa redunhu bhodhi isina mitezo pairi.
