Munyika inonakidza yemagetsi, PCB kana Printed Circuit Board chinhu chakakosha chinowanzo furatirwa neavhareji mushandisi. Kunzwisisa zvinoreva uye kukosha kwePCB kwakakosha kuti ubate kushanda kwakaoma kwemidziyo yemagetsi. Mune ino blog, tichaongorora nyika yePCB, tichiburitsa chinangwa chavo, dhizaini, uye kukosha kwavo mumagetsi emazuva ano.
1. Chii chaizvo chinonzi PCB?
A rakadhindwa redunhu bhodhi (PCB) iri flat panel yakagadzirwa neasina-conductive zvinhu, kazhinji fiberglass, inoshandiswa kubatanidza uye kutsigira akasiyana emagetsi zvikamu. Izvi zvikamu zvinotengeswa kubhodhi, zvichibvumira magetsi kuyerera uye kuve nechokwadi kuti mudziyo unoshanda zvakanaka. MaPCB anoshandiswa mumidziyo yakawanda yemagetsi, kubva kumafoni nemakomputa kuenda kumidziyo yemumba nemota.
2. Kukosha kwePCB mundima yemagetsi:
Chinangwa chakakosha chePCB ndechekupa chikuva chakasimba uye chakavimbika chekubatanidzwa kwezvinhu zvemagetsi. PCB dhizaini uye dhizaini yakanyatso kurongwa kuti ive nechokwadi chekuita kwakaringana, kufambiswa kwechiratidzo kwakanaka uye kushandiswa kwenzvimbo. Pasina PCB, zvikamu zvemagetsi zvingave zvakashata uye zvisingavimbiki, zvichikonzera kushanda kusina kunaka.
3. PCB kuvaka uye dhizaini:
MaPCB ane ma-multi-layer structure, ane layer yega yega inoshanda chinangwa chakati. Iyo yemukati-kati inonzi substrate uye inopa mechanical tsigiro yedare redunhu. Isa chidimbu chakatetepa chemhangura pamusoro peiyo substrate kuti iite maitiro ekuitisa. Aya maronda anoita semakwara azvino, achibvumira zvikamu kuti zvitaurirane.
Kuve nechokwadi chekuti zvikamu zvakachengetedzwa zvakachengeteka, mapadhi anowedzerwa kune PCB pamusoro. Aya mapadhi anoshanda semapoinzi ekubatanidza kune akasiyana emagetsi zvinhu senge resistors, capacitors, uye akasanganiswa maseketi. Magadzirirwo ekugadzira aisanganisira kuenzanisa pakati pekushanda, kusakura kwezvipingamupinyi uye kudhura-kushanda.
4. Nzira yekugadzira:
Kugadzira maPCB kunosanganisira matanho akawanda, anosanganisira dhizaini, kugadzira, uye kusangana. Kana dhizaini yapera uchishandisa nyanzvi yekombuta-inobatsira dhizaini (CAD) software, maitiro ekugadzira anotanga. Zvinowanzo sanganisira kudhinda mapatani edunhu pabhodhi-yakavharwa bhodhi, maburi ekuboora maburi-maburi, uye kushandisa otomatiki muchina kukwidza zvinhu pabhodhi.
5. Kufambira mberi muPCB tekinoroji:
PCB tekinoroji yakashanduka zvakanyanya nekufamba kwemakore, ichiwedzera compact, inoshanda uye ine hushamwari. Kuunzwa kwepamusoro-soro tekinoroji (SMT) kwafambisa kugadzirwa kwePCB diki, dzakatetepa, zvichiita kuti pave nemhando yepamusoro, inotakurika michina yemagetsi.
Pamusoro pezvo, kufambira mberi senge anochinjika akadhindwa edunhu mabhodhi (mabhodhi edunhu anogona kupetwa kana kupetwa) akashandura indasitiri inopfeka tekinoroji. Flexible PCBs inovandudza kusimba uye kushandiswa kwenzvimbo, kugadzira nzvimbo yekugadzira dhizaini uye mashandisirwo.
Mabhodhi edunhu akadhindwa (PCBs) anoita basa rakakosha mukushanda kwemidziyo yedu yemazuva ese yemagetsi. Kubva pamafoni emafoni kusvika kumota, kunzwisisa kuti PCB chii kunotibatsira kunzwisisa kuomarara uye kugona kwehunyanzvi kuseri kwemidziyo iyi. MaPCB haangopi kugadzikana chete asiwo anovhura nzira yekumwe budiriro mumunda wemagetsi.
