Mabhodhi Emagetsi Akadhindwa (PCBs) chikamu chakakosha chemidziyo yemagetsi yemazuva ano, inoshanda sehwaro hwezvinhu zvinoita kuti michina iyi ishande. MaPCB anoumbwa nezvinhu zvepasi, zvinowanzogadzirwa nefiberglass, zvine nzira dzinofambisa mhepo dzakachekwa kana kudhindwa pamusoro kuti zvibatanidze zvikamu zvakasiyana-siyana zvemagetsi. Chimwe chinhu chakakosha pakugadzira maPCB kuputira, uko kunoita basa rakakosha mukuona kuti PCB inoshanda uye yakavimbika. Muchinyorwa chino, tichaongorora maitiro ePCB plateing, kukosha kwayo, uye mhando dzakasiyana dzeplateing dzinoshandiswa mukugadzira maPCB.
Chii chinonzi PCB Plating?
Kuisa simbi yakatetepa pamusoro pePCB substrate uye panzira dzinofambisa mvura. Kuisa simbi uku kunobatsira pazvinangwa zvakasiyana-siyana, zvinosanganisira kuwedzera kufambiswa kwemvura munzira, kudzivirira nzvimbo dzemhangura dzakaonekwa kubva mukuora nekuoxidation, uye kupa nzvimbo yekusonera zvinhu zvemagetsi pabhodhi. Kuisa simbi iyi kunowanzoitwa uchishandisa nzira dzakasiyana-siyana dzemagetsi, dzakadai sekuisa simbi isina electro kana kuisa electroplating, kuti uwane ukobvu hwaunoda uye hunhu hwepurasitiki.
Kukosha kwePCB Plating
Kuisa maPCB kwakakosha nekuda kwezvikonzero zvakati wandei. Chekutanga, kunovandudza kufambiswa kwenzira dzemhangura, zvichiita kuti masaini emagetsi afambe zvakanaka pakati pezvikamu. Izvi zvakakosha zvikuru mukushandiswa kwemafrequency akawanda uye nekukurumidza uko kusimba kwemasaini kuri kukuru. Pamusoro pezvo, jira rakaiswa jira rinoshanda sechidziviriro pazvinhu zvakaita sehunyoro netsvina, izvo zvinogona kukanganisa mashandiro ePCB nekufamba kwenguva. Uyezve, kuisa jira kunopa nzvimbo yekunamatira, zvichiita kuti zvikamu zvemagetsi zvibatanidzwe zvakanaka pabhodhi, zvichigadzira kubatana kwemagetsi kwakavimbika.
Mhando dzePCB Plating
Kune mhando dzakasiyana dzema plating dzinoshandiswa mukugadzira ma PCB, imwe neimwe ine hunhu hwayo hwakasiyana uye mashandisirwo ayo. Dzimwe dzemhando dzakajairika dzema plating e PCB dzinosanganisira:
1. Electroless Nickel Immersion Gold (ENIG): ENIG plating inoshandiswa zvakanyanya mukugadzira PCB nekuda kwekudzivirira kwayo ngura uye kugona kwayo kusanganisa zvinhu. Ine chidimbu chakatetepa chenickel isina electron ichiteverwa nechidimbu chegoridhe rinonyudzwa, zvichiita kuti pave nepamusoro pakaita sepakanaka uye pakanaka pakusanganisa zvinhu ukuwo ichidzivirira mhangura kubva mukusanganiswa kwemafuta.
2. Goridhe Rakaputirwa Nemagetsi: Goridhe rakagadzirwa nemagetsi rinozivikanwa nekugona kwaro kufambisa mvura zvakanaka uye kuramba kusvibiswa, zvichiita kuti rikwanise kushandiswa panodiwa kuvimbika kwakanyanya uye kugara kwenguva refu. Rinowanzo shandiswa mumidziyo yemagetsi yepamusoro uye muzvishandiso zvemuchadenga.
3. Tin yakaputirwa neElectroplated: Kuputirwa netin kunowanzo shandiswa senzira isingadhuri yePCB. Kunogoneka kuchinjika uye kuramba ngura, zvichiita kuti ikodzere kushandiswa pabasa rose kana mutengo uri chinhu chakakosha.
4. Sirivha yakaputirwa neElectroplated: Kuputirwa kwesirivha kunopa simba rakanaka uye kunowanzo shandiswa mumashandisirwo epamusoro-soro uko kusimba kwemasaini kwakakosha. Zvisinei, kunowanzo sviba kana tichienzanisa nekuputirwa kwegoridhe.
Maitiro Ekugadzira Mapuratifomu
Maitiro ekuisa simbi mupurasitiki anowanzo tanga nekugadzirira PCB substrate, iyo inosanganisira kuchenesa nekuita kuti pamusoro payo pave nechokwadi chekuti simbi yakabatana zvakanaka. Panyaya yekuisa simbi mupurasitiki isina electrolyte, bhavhu remakemikari rine simbi inoshandiswa kuisa simbi mupurasitiki mupurasitiki kuburikidza ne catalytic reaction. Kune rumwe rutivi, kuisa simbi mupurasitiki kunosanganisira kunyudza PCB mu electrolyte solution uye kupfuudza magetsi kuburikidza nayo kuti simbi ipinde pamusoro.
Munguva yekuputira, zvakakosha kudzora ukobvu uye kufanana kwechikamu chakaputirwa kuti zvienderane nezvinodiwa zvePCB design. Izvi zvinoitwa kuburikidza nekudzora kwakanyatsojeka maparamita epurasitiki, akadai sekuumbwa kwemhinduro yekuputira, tembiricha, huwandu hwemazuva ano, uye nguva yekuputira. Matanho ekudzora hunhu, kusanganisira kuyerwa kweukobvu uye bvunzo dzekunamatira, anoitwawo kuti ave nechokwadi chekuti chikamu chakaputirwa chakasimba.
Matambudziko uye Zvaunofanira Kufunga Nezvedu
Kunyange zvazvo kuputira PCB kuchipa mabhenefiti akawanda, kune mamwe matambudziko nezvimwe zvinhu zvinofungwa nezvazvo zvine chekuita nemaitiro acho. Dambudziko rimwe chete rinowanzoitika nderekuwana ukobvu hwakafanana hwekuputira PCB yese, kunyanya mumagadzirirwo akaomarara ane huwandu hwakasiyana hwezvinhu. Zvinhu zvakakodzera zvekugadzira, zvakaita sekushandisa masks ekuputira uye zvinodzorwa ne impedance traces, zvakakosha kuti pave nechokwadi chekuti kuputira kwakafanana uye kushanda kwemagetsi nguva dzose.
Kufunga nezvezvakatipoteredza kunoitawo basa guru mukuputira maPCB, sezvo makemikari nemarara anokonzerwa panguva yekuputira maPCB zvinogona kukanganisa nharaunda. Nekuda kweizvozvo, vagadziri vazhinji vePCB vari kushandisa maitiro ekuputika nezvinhu zvine hushamwari kune nharaunda kuti vaderedze kukanganisa nharaunda.
Pamusoro pezvo, sarudzo yezvinhu zvekuputira uye ukobvu zvinofanirwa kuenderana nezvinodiwa zvePCB application. Semuenzaniso, maseketi edhijitari anomhanya zvikuru anogona kuda kuputira kwakakora kuti aderedze kurasikirwa kwechiratidzo, nepo maseketi eRF nema microwave anogona kubatsirwa nezvinhu zvepurasitiki zvakanongedzerwa kuchengetedza kusimba kwechiratidzo pamafrequencies akakwira.
Mafambiro Emangwana muPCB Plating
Sezvo tekinoroji ichiramba ichifambira mberi, basa rePCB plating riri kufambira mberiwo kuti risangane nezvinodiwa nemidziyo yemagetsi yechizvarwa chinotevera. Imwe nzira inozivikanwa ndeyekuvandudzwa kwezvinhu zvepamusoro zveplating uye maitiro anopa kushanda kwakanaka, kuvimbika, uye kuchengetedzeka kwezvakatipoteredza. Izvi zvinosanganisira kutsvaga dzimwe simbi dzeplating uye kupedzisa kwepamusoro kugadzirisa kuoma kuri kukura uye kuderedzwa kwezvikamu zvemagetsi.
Uyezve, kubatanidzwa kwehunyanzvi hwepamusoro hwekuputira, hwakadai sepulse nereverse pulse plating, kuri kuwedzera kusimba kuti pave nehukuru hwakanaka uye huwandu hwepamusoro hwemagadzirirwo ePCB. Maitiro aya anogonesa kutonga kwakanyatsojeka pamusoro pemaitiro ekuputira, zvichikonzera kufanana uye kuenderana kwakawedzerwa muPCB yese.
Mukupedzisa, kuputira maPCB chinhu chakakosha pakugadzirwa kwePCB, zvichiita basa guru mukuona kuti zvishandiso zvemagetsi zvinoshanda zvakanaka, zvakavimbika, uye zvinoshanda. Maitiro ekuputira maPCB, pamwe chete nesarudzo yezvinhu zvekuputira maPCB nematekiniki, zvinokanganisa zvakananga hunhu hwemagetsi nehwemakanika hwePCB. Sezvo tekinoroji ichiramba ichifambira mberi, kuvandudzwa kwemhinduro dzekugadzira maPCB itsva kuchave kwakakosha kuti kugutse zvinodiwa neindasitiri yezvemagetsi zviri kuchinja, zvichitungamira kufambira mberi nekuvandudzwa mukugadzirwa kwePCB.
