Mugadziri wePCB & PCBA weindasitiri
Mabhodhi edunhu emuchina wekudzora maindasitiri - Mabhodhi edunhu emuchina wekudzora maindasitiri
PCBA yemuindasitiri, inozivikanwawo sebhodhi rekudzora maindasitiri, ibhodhi redunhu rakagadzirirwa kutsungirira kuvhunduka, kudedera, tembiricha yakanyanya, hunyoro, uye guruva mumidziyo yemuindasitiri. PCBA iyi inoshandiswa kuita mabasa akawanda muindasitiri yekudzora maindasitiri. Yakagadzirirwa kugadzirisa dunhu repurojekiti nenzira diki, iyo inobvumira magetsi kuti afambe nemazvo munzira inodiwa uye inowedzera mashandiro echigadzirwa. Mabhodhi aya zvakare zvikamu zvakakosha zvemapurojekiti ekutonga maindasitiri nemidziyo, zvichibatsira kuyera nekugadzirisa maparamita akawanda emutsetse wekubatanidza, uye kuwana huwandu hwakarurama hwemuviri.
Kambani yePCBA yeMidziyo yeIndasitiri - Richpcba
Kana uchitsvaga mabhodhi ePCB/PCBA emhando yepamusoro ekugadzirisa maindasitiri nemitengo inokwanisika, www.richpcba.com ndiyo nzira yakanakisisa. Yakatangwa muShenzhen, China muna 2004, tiri vagadziri vePCB vakashanda zviuru zvemabhizinesi emuno neekunze kwemakumi emakore apfuura. Mabasa edu ekugadzira haasi ePCB nePCBA chete; tinoitawo zvinodiwa, kugadzirisa, uye kugadzirisa zvinodiwa nevatengi kuti vagutsikane. Kuburikidza nemaitiro edu ebasa rehunyanzvi uye maitiro edu ekushanda akazvipira, tave tichizivikanwa nevagadziri vakawanda vanotungamira mumunda wemaindasitiri.
Isu tine hunyanzvi mukugadzira maPCB emaindasitiri ane layer yakawanda uye tinopa masevhisi ePCBA anomira kamwe chete. Maitiro edu anotanga nefaira kana Gerber inotumirwa nemushandisi. Mushure mekugamuchira faira iri, mainjiniya edu anoongorora uye anogadza maitiro ekugadzira kuti vagadzire mabhodhi ePCB nezvinhu zvePCBA zvekudzora maindasitiri vachishandisa matekinoroji akasiyana. RICHPCBA inogona kusangana nezvinodiwa nevatengi vemapurojekiti ari nyore kusvika akaomarara, madiki kusvika kuunganidzwa wePCB wakawanda, uye mabhizinesi matsva kusvika kumakambani makuru emaindasitiri. Chikwata chedu chenyanzvi chinoita mapurojekiti kuburikidza nevatariri vemapurojekiti e1V1, vachitsigirwa nevatengi vekutenga, mainjiniya, kugadzira, uye timu dzekutarisa mhando.

Zvinhu zvekugadzira PCB yeindasitiri
Kurongeka kweZvikamu
Kuiswa kwezvikamu pabhodhi chinhu chakakosha chekufunga nezvacho pakugadzira mabhodhi ePCB ekudzora maindasitiri. Kuiswa kwezvikamu zvisina kunaka kunogona kukanganisa kuvimbika uye mashandiro echigadzirwa chekupedzisira. Panguva yekugadzira bhodhi rePCB, kungwarira kwakakosha kunofanirwa kutorwa kuona kuti zvikamu zvakaiswa pabhodhi nenzvimbo inosvika 100 mils pakati pemipendero yebhodhi nezvikamu zvakasungirirwa. Izvi zvinovimbisa kuti zviyero zvebhodhi nemaburi akasungirirwa zvinoenderana.
EMI neRFI
Mukushandiswa kwemaindasitiri, zvakakosha kuderedza migumisiro yeElectromagnetic Interference (EMI) uye Radio Frequency Interference (RFI), izvo zvinogona kukonzera ruzha uye kukanganisa mashandiro ePCBA. Kuti izvi zviitike, Rich PCBA inopa nzira dzakasiyana siyana:
Marongerwo ebhodhi: Kuti muderedze njodzi yekubatana kweruzha, paradzanisai macircuit ane mafrequency akakwira kubva kumacircuit ane mafrequency akaderera uye chengetedzai masignal traces kure nemagetsi nepasi. Masignal traces anofanira kunge mapfupi sezvinobvira, nepo mapower nepasi zvichifanira kunge zvakakura sezvinobvira uye zvichiendeswa kune maburi emuchina wakaderera wekubatanidza kuti network yemagetsi isapindike zvakanyanya.
Zvikamu zvekusefa: Wedzera zvinhu zvekusefa zvakaita sema capacitor nema inductors kumagetsi uye pamitsara yezviratidzo kuti usefe ruzha rusingadiwe.
Matekiniki eKudzika neKudzivirira: Isa zvinhu zvinonzwa zviri nyore mumakeji eFaraday kuti zvivhare EMI neRFI.
Kusarudzwa kweZvikamu: Sarudza zvikamu zvebhodhi redunhu zvine grounding uye shielding yemhando yepamusoro. Shandisa tambo dzakavharirwa kubatanidza bhodhi kune zvishandiso zvekunze kudzivirira kubatana kwechiratidzo chisingadiwi.
Zvinhu zvePCB zvekudzora maindasitiri
Kusarudzwa kwezvinhu zvekugadzira maPCB kwakakosha uye kunofanirwa kuenderana nenzvimbo chaiyo yekushanda. Zvinhu zvemaPCB zvinoshandiswa mumaindasitiri zvinofanirwa kukwanisa kutsungirira mamiriro akaoma, akadai sekupisa kwakanyanya, voltage yakakwira, hunyoro, kudedera, uye kusangana nemakemikari. Zvimwe zvinhu zvinowanzoshandiswa zvemaPCB emaindasitiri ndeizvi:
● Polyimide: Chinhu ichi chinoshanda zvakanaka chinogona kutsungirira tembiricha yakanyanya kusvika 400°C uye chinowanzoshandiswa muzvinhu zvinodzora zvinhu mundege, zvehondo, uye muindasitiri.
● Ceramic: PCB yeceramic yakagadzirwa nesimbi yakacheneswa nesimbi. Ine simba rakanaka rekupisa uye inogona kubata tembiricha yakakwira uye makemikari akaomarara. Inowanzoshandiswa mumagetsi ane simba uye mashandisirwo emagetsi ane frequency yakakwira.
● PTFE: PTFE kana polytetrafluoroethylene ifluoropolymer ine hunhu hwakanaka hwemagetsi hunochengetedza hunodzivirira hunogona kutsungirira tembiricha yepamusoro kusvika 260°C. Inowanzoshandiswa munzvimbo dzinoshandiswa ma frequency akawanda uye muma microwave, pamwe nenzvimbo dzine makemikari akaomarara.
● FR-4: Iyi jira rakagadzirwa nefiberglass rakarukwa uye epoxy resin ndiyo inonyanya kushandiswa paPCB, kusanganisira maindasitiri. FR4 PCB ine hunhu hwakanaka hwekudzivirira kupisa uye inogona kutsungirira kupisa kwakanyanya uye makemikari.
