Ndeapi Mhando dzakasiyana dzePCB?
MaPCB units aripo mumhando dzakasiyana-siyana dzemashandisirwo akasiyana-siyana. Kusarudza chivakwa chakakodzera chechigadzirwa kunoda kuti mainjiniya afunge nezvekushandiswa kwaunoda kwechishandiso, saizi yacho uye simba rayo. Ongorora zvinotevera kuti unzwisise mhando dzemabhodhi edunhu akadhindwa uye kuti ndeapi marudzi akakodzera mabasa ako:
MaPCB ane divi rimwe chete: Kugadzirwa kwePCB kunosanganisira kugadzira bhodhi redunhu kubva pachikamu chimwe chete che substrate nechikamu chitete chesimbi. Zvikamu zvese zvinosungirirwa padivi rimwe chete.
MaPCB ane mativi maviri: Rudzi rwePCB uko machira esimbi anofambisa mhepo anoiswa kumativi ese e substrate.
Maburi anogona kuboorwa nepakati pebhodhi redunhu kuti zvibatanidzwe kumativi ese.
MaPCB Akasiyana-siyana: Anenge maPCB matatu ane mativi maviri akasungirirwa pamusoro peimwe neimwe nematanho akati wandei ekudzivirira kupisa kuti aderedze kutapurirana kwekupisa. Manamatiro akakosha anonamira anochengetedza maPCB akatevedzana.
MaPCB Anochinjika: Mabhodhi edunhu akadhindwa anoratidza ma substrates anochinjika kubatsira mainjiniya kugadzirisa maumbirwo ezvigadzirwa zvidiki. Tekinoroji iyi inogona kuvapo muchimiro chekuvaka kwemativi maviri, mativi maviri kana akawanda.
MaPCB Akasimba: Anobatsira kune zvigadzirwa zvinogara zvakaita seizvi muhupenyu hwazvo hwese. MaPCB akasimba anogadzirwa achishandisa zvinhu zvakasimba zvinoramba kumonyoroka.
MaPCB akapfava uye anochinjika: Mabhodhi edunhu akadhindwa achishandisa zvinhu zvakasimba uye zvinochinjika. Magadzirirwo aya anobvumira vagadziri vezvigadzirwa kuchengetedza nzvimbo, sezvo nzira dzekubatanidza dzakapfava uye dzinochinjika dzinogona kuiswa pabhodhi redunhu rimwe chete.
MaPCB ane Aluminium-backed: Rudzi rwePCB runotsiva substrate yearuminiyamu uko fiberglass ichave. Yakagadzirirwa kushandiswa nemagetsi ePCB ane simba guru akadai semwenje ye LED.
MaPCB ane mafrequency akakwira: Bhodhi redunhu rakagadzirwa kuti ritumire masaini akasimba se2 GHz.
Chii Chinogadzirwa nePCB?
Maitiro ekugadzira PCB anotaridzika zvakasiyana zvichienderana nechinangwa cheyuniti uye kuti simba rakawanda sei rinodiwa kuti mudziyo wemagetsi ushande. Usati wasarudza zvinhu zvekubatanidza bhodhi redunhu, zvakanaka kuti uzive zvikamu zvina zvikuru zveyuniti yePCB:
Substrate: Chimiro chebhodhi redunhu — zvese zvikamu zvinonamira pamusoro apa.
Laminates: Zvinhu zvinobatanidza zvikamu zvese zvePCB pamwe chete.
Chifukidzo chesolder: Chinogara pamusoro pemafoil emhangura kuti chisaparadzwe uye chinodzivirira kubatana kubva kuzvinhu zvakatipoteredza.
Sikirini yeSiriki: Inonamira pamasiki anosungirirwa kuitira kuti zvikamu zvacho zvigone kunyorwa.
Chii chinonzi chirongwa chehurongwa?
Dhayagiramu yezvirongwa, kana kuti dhayagiramu, inomiririra zvinhu zvehurongwa uchishandisa zviratidzo zvisinganzwisisike, zvemifananidzo panzvimbo pemifananidzo chaiyo.
Ndezvipi zvinounzwa nebasa rePCB Layout?
Kune maodha ebasa rePCB Layout, data rinotevera richapihwa mufaira rekubuda:
Madhatabhesi akazara eGerber anosanganisira mafaira eDrill (Majira eCircuit, Mask layers, Silk layers, Outline, Majira eDrill, Matanda ePaste)
Ruzivo rwekusarudza & nzvimbo
Faira rekupedzisira reBhiri reZvinhu
Runyorwa rweProjekiti nefaira rePDF
Ndezvipi zvinhu zvinowanzo shandiswa kugadzira maPCB akaomarara?
Zvinhu zveFR4
Zvinhu zvinomhanya zvakanyanya zvechiratidzo
Substrate yeFR4 inomhanya zvikuru ine DF 1Ghz.
Substrate yeFR4 inomhanya zvikuru ine Df 10Ghz
Zvinhu zveceramic zveDf yakaderera, mashandiro pa10Ghz
Zvinhu zvePTFE kana zvinhu zvePTFE zvakasimbiswa
Zvinhu zvePTFE zvinopisa zvakanyanya
Ndedzipi nzira dzekugadzira dzinoshandiswa kugadzira maPCB akaomarara?

Zvinotora nguva yakareba sei kugadzira PCB yakaoma?
Zvinotevera ndezvenguva inodiwa kugadzira maPCB akaomarara muRichfulljoy.
Zvinotora mazuva 1-5 kuti maPCB akasimba akwanise kuchinjika nekukurumidza.
Mavhiki 1-2 anotorwa kuti pave nemaprototypes uye maPCB akatevedzana madiki.
Mavhiki maviri kusvika mana anoshandiswa pakugadzira akawanda maPCB akaomarara.
Musiyano mukuru ndeupi: PCB yakasimba vs PCB inochinjika?
Musiyano mukuru uripo pakati pebhodhi rePCB rakaomarara nebhodhi rePCB rinochinjika ndewekuti:
1), Dzinogadzirwa nezvinhu zvakasiyana: mabhodhi edunhu akaomarara anogadzirwa neFR4, ceramic, simbi, PTFE nezvimwewo, ese akaomarara (haagone kukotama), nepo PCB inochinjika inogadzirwa nepolyimide(PI), PET, Kapton matrial inogona kukotama kane zviuru;
2), Kana zvichikwanisa kupetwa kana kuti kwete: PCB yakasimba haigone kupetwa, asi PCB inochinjika inogona kupetwa;
3), Anoshandiswa zvakasiyana: mabhodhi emagetsi akasimba anoshandiswa mumidziyo yemagetsi isingafambi, asi mabhodhi emagetsi anochinjika anoshandiswa mumidziyo inogara ichifamba, senge makamera, malaptop, nharembozha, maprobe anofamba nezvimwewo.
Zvinodhura marii kugadzira PCB yakaoma?
Zvakaoma kutaura kuti PCB yakasimba ingani. Zvinotevera ndezvezvinhu zvikuru zvinokanganisa mutengo wePCB yakasimba.
