Kuongorora Kwemhando / Kuedza
Kuongororwa kwePCB kunoita bvunzo dzakasiyana pamabhodhi edunhu akadhindwa kuti aone kunaka uye mashandiro awo, kuve nechokwadi kubviswa kwakaringana kwechero hurema kana nyaya dzinogona kuitika panguva yekugadzira, kuona kana vachikwanisa kuzadzisa zvakatemwa uye kuita, uku vachivandudza kushanda nesimba uye kuderedza mitengo.Mari yekupedzisira.
Tinogona kupa akasiyana PCB ekuongorora masevhisi, anosanganisira:
Manual/Visual Inspection:Isu tine ruzivo rwePCB inspectors vanosanganisa manyorero ekuona yekuongorora mune akawanda bvunzo kuti ive nechokwadi chekuongorora kwakakwana kwePCB uye zvikamu zvadzo, kuve nechokwadi chemhando yechigadzirwa.
Microscopic slice kuongororwa:Kuongorora kwechimedu kwePCB kunosanganisira kucheka bhodhi redunhu kuita zvikamu zvitete kuti zvionekwe uye kuongororwa, kuitira kuona zvingangoitika matambudziko uye hurema.
Kuongororwa kwechidimbu kunowanzoitwa mumatanho ekutanga ekugadzira bhodhi redunhu kuti ive nechokwadi chekuonekwa nekugadziriswa kwenyaya panguva yekugadzira uye kugadzira.Iyi nzira inogona kutarisa welding, interlayer connections, magetsi echokwadi, nezvimwe nyaya.Paunenge uchiitisa bvunzo dzebiopsy, maikorosikopu kana scanning electron microscope inowanzo shandiswa kuona uye kuongorora zvimedu.
PCB magetsi ekuongorora:PCB yemagetsi yekuyedza inogona kubatsira kusimbisa kana magetsi maparamendi uye kuita kwedhipatimendi redunhu zvinosangana zvinotarisirwa, uye zvakare inogona kuona hurema uye matambudziko.
PCB yemagetsi yekuyedza inowanzo sanganisira yekubatanidza kuyedza, kuyedza kuyedza, kuyedza kugona, kuyedza impedance, chiratidzo chekuvimbika kuyedzwa, uye kuyedza mashandisiro emagetsi.
PCB yemagetsi yekuyedza inogona kushandisa midziyo yekuyedza dzakasiyana uye nzira, senge kuyedza zvigadziriso, madhijitari multimeter, oscilloscopes, spectrum analyzers, nezvimwewo. Mhedzisiro yebvunzo ichanyorwa mumushumo webvunzo kuti uongororwe uye kugadziriswa kwebhodhi redunhu.
Kuedzwa kweAOI:Kuongorora kweAOI (Automated Optical Inspection) inzira yekuona otomatiki mabhodhi edunhu akadhindwa kuburikidza nenzira dzemaziso.Inogona kushandiswa kukurumidza kuona kukanganisa uye matambudziko mukugadzira maitiro eakadhindwa edunhu mabhodhi, kudzivirira zvikanganiso mukugadzirwa kwechigadzirwa, uye kuvandudza kunaka kweakadhindwa edunhu mabhodhi.Hunhu hwakavimbika, kudzikisira mitengo yekukundikana, nekuvandudza hunyanzvi hwekugadzira uye goho rechigadzirwa.
Mukuongorora kweAOI, midziyo yekuona yakaita semakamera akakwira-resolution, magetsi, uye software yekugadzirisa mifananidzo inoshandiswa kuongorora nekutora mifananidzo yePCB yakagadzirwa, uye ipapo mifananidzo yakatorwa inofananidzwa netemplate yagara yaiswa.Ehe, kuti uone otomatiki hurema uye nyaya, kusanganisira solder majoini, zvikamu, mapfupi maseketi uye akavhurika maseketi, chokwadi, kuremara kwepasi, nezvimwe.
ICT:MuCircuit Test inoshandiswa kuyedza zvinhu zvemagetsi uye dhizaini yekubatanidza kuita pane redunhu bhodhi.Kuongororwa kweICT kunogona kuitwa pamatanho akasiyana ekugadzirwa kwePCB, sekunge mushure mekugadzira PCB, isati yasvika kana mushure mekuisa chikamu, kukurumidza kuona nekugadzirisa matambudziko pabhodhi redunhu uye nekuagadzirisa nenguva.
Kuyedzwa kweICT kunoshandisa hunyanzvi hwekuyedza uye software kuti iedze otomatiki zvikamu zvemagetsi uye zvinongedzo paPCB.Midziyo yekuyedza inobata mapoinzi ebvunzo pabhodhi redunhu kuburikidza nemaprobes uye mabhanhire kuti aone hunhu hwemagetsi ezvikamu zvemagetsi pabhodhi redunhu, senge resistors, capacitors, inductors, transistors, nezvimwe. Zvinogoneka zvakare kuyedza bhodhi redunhu kuti iva nechokwadi chokuti magetsi ayo akabatanidzwa anoshanda sezvakagadzirwa.
Flying Needle Test:Flying Needle Test inoshandisa otomatiki probe sisitimu yekuyedza kutenderera kwekubatanidza uye kushanda paPCB.Iyi nzira yekuyedza haidi zvinodhura zvigadziriso zvekuyedza uye nguva yekuronga, asi pachinzvimbo inoshandisa inofambiswa probes kubata iyo PCB pamusoro kuyedza yekubatanidza dunhu uye mamwe ma paramita.
Kubhururuka tsono kuyedzwa inzira isiri yekuonana yekuyedza iyo inogona kuyedza chero nzvimbo yedunhu bhodhi, kusanganisira diki uye dense redunhu mabhodhi.Zvakanakira nzira iyi yekuyedza mutengo wakaderera wekuyedza, nguva pfupi yekuyedza, kureruka kwekushanduka kwedhizaini dhizaini shanduko, uye nekukurumidza sampuli kuyedzwa.
Functional circuit test:Inoshanda dunhu rekuyedza inzira yekuitisa bvunzo inoshanda paPCB kuona kana dhizaini yayo inosangana nezvakatemwa uye zvinodiwa.Iyo yakazara nzira yekuyedza iyo inogona kushandiswa kutarisa mashandiro, chiratidzo chemhando, yekubatanidza dunhu, uye mamwe mabasa ePCB.
Kushanda kwedunhu kuyedzwa kunowanzoitwa mushure mekunge PCB wiring yapedzwa, uchishandisa zvigadziriso zvekuyedza uye zvirongwa zvekuyedza kutevedzera chaiwo mamiriro ekushanda ePCB uye kuyedza mhinduro yayo pasi pemaitiro akasiyana ekushanda.Chirongwa chekuyedza chinogona kuitwa kuburikidza nesoftware programming, iyo inogona kuyedza akasiyana mabasa ePCB, kusanganisira yekupinza / kubuda, nguva, magetsi emagetsi, ikozvino uye mamwe ma paramita.Panguva imwecheteyo, peji ino inogona kuona zvakawanda zvingangoitika nePCB, senge mapfupi maseketi, akavhurika maseketi, kubatanidza zvisirizvo, nezvimwewo, uye anogona kuona nekukasika uye kugadzirisa nyaya idzi kuti ive nechokwadi chekuita uye kuvimbika kwePCB.
Inoshanda dunhu rekuyedza inzira yekuyedza yakasarudzika inoda hurongwa uye yekuyedza dhizaini yePCB yega yega.Naizvozvo, mutengo wacho wakakwira zvakati, asi unogona kupa huwandu hwakazara, hwakarurama, uye hwakavimbika bvunzo mhinduro.
