Kudzivirira maburi mukuputira uye neTlding inosanganisira kuyedza maitiro matsva ekugadzira uye kuongorora mhedzisiro. Plating uye Welding Invonesi inowanzo kuve inozivikanwa zvinokonzeresa, senge mhando yemutengesi pasita kana kudhirai zvishoma kushandiswa muitiro yekugadzira. PCB Vagadziri vanogona kushandisa nhamba yeiyi nzira dzinokosha kuti uzive uye kero zvakajairika zvinokonzeresa zviratidzo izvi.
1.Ad Sirat Sired iyo Reflux tembiricha curve
Imwe yenzira dzekudzivirira kutambisa matangi ndeyekugadzirisa nzvimbo yakaoma yeiyo Reflux curve. Kupa matanho akasiyana enguva kunogona kuwedzera kana kuderedza mukana weiyo vhoti inoumba. Kunzwisisa iyo yakakodzera kudzoka curve maitiro anokosha kuti abvumidzwe zvinobudirira Cavity Kudzivirira.
Kutanga, tarisai zvirongwa zvazvino nguva dzinodziya. Edza kuwedzera kupisa kwekushisa kana kuendesa nguva yekupedza yeratlux curve. Makomba ekutengesa anogona kuumbwa nekuda kwekusakwana kwekupisa munzvimbo yekunyepedzera, saka shandisa izvi mazano ekugadzirisa nzira inokonzeresa.
Homogeneous kupisa nzvimbo nzvimbo zvakare dzinozivikanwa dzinozivikanwa mumavhayiwi Pfupi nguva yekudzika nguva ingasabvumira zvese zvikamu uye nzvimbo dzebhodhi kuti dziregedze tembiricha inodiwa. Edza kubvumira imwe nguva yekuwedzera yenzvimbo ino yeirpax curve.
2.use zvishoma flux
Kunyanyisa kuwanda kunogona kuwedzera uye kazhinji kunotungamira kuWelding. Rimwe dambudziko neiyo yakabatana cavity: Flux Deglessing. Kana iyo flux isina nguva yakakwana yekugezesa, gasi rakawandisa richabatwa uye risina chinhu ichaumbwa.
Kana yakawandisa flux inoiswa kune iyo PCB, iyo nguva inodiwa kuti iregedhi ive degree ranyatsowedzerwa. Kunze kwekunge iwe unowedzera imwe nguva diki, yekuwedzera flux ichaguma neWeld Invon.
Paunenge uchiwedzera imwe dhigirii nguva inogona kugadzirisa dambudziko iri, inonyanya kushanda kuti inamatira kune huwandu hwehuwandu hunodiwa. Izvi zvinoponesa simba uye zviwanikwa uye zvinoita kuti majoini akachena.
3.use chete yakapinza inodhiraira mabheti
Chikonzero chakajairika chekutanga maburi ane urombo kuburikidza negomba rinokwevera. Dull mabheti kana kurongeka kwekuchera kurongeka kunogona kuwedzera mukana wekuumbwa kwemarara panguva yekudhirowa. Kana zvidimbu izvi zvinamatira pcb, ivo vanogadzira nzvimbo dzisina chinhu dzisingagoni kuve dzakarongedzwa nemhangura. Izvi zvinokanganisa ngachiite, hunhu uye kuvimbika.
Vagadziri vanogona kugadzirisa dambudziko iri nekushandisa chete rakapinza uye rakapinza drill bits. Gadzira chirongwa chisingareruka chekupinza kana kutsiva mabhedhi ekurova, senge makota. Uku kugadziriswa kwekugara kunogara kuchisimbisa ne-gomba rinokwevera mhando uye kuderedza mukana wemarara.
4.RY dzakasiyana template dhizaini
Iyo template dhizaini inoshandiswa muFloclo maitiro inogona kubatsira kana kukanganisa kudzivirira kwemavhondi. Nehurombo, hapana imwe-saizi-inokodzera-ese mhinduro kune template dhizaini sarudzo. Dzimwe dhizaini dzinoshanda zviri nani nemutengesi akasiyana pasita, flux, kana PCB mhando. Zvinogona kutora imwe muyedzo uye kukanganisa kuwana sarudzo kune imwe mhando yebhodhi yemhando.
Kubudirira kuwana iyo chaiyo template dhizaini inoda maitiro akanaka ekuedza. Vagadziri vanofanirwa kuwana nzira yekuyera uye kuongorora mhedzisiro yeiyo fomu dhizaini pane voids.
Nzira yakavimbika yekuita izvi ndeyekugadzira batch yePCB ine yakatarwa template dhizaini uye wobva waongorora zvakakwana. Templates dzinoverengeka dzakasiyana dzinoshandiswa kuita izvi. Kuongorora kunofanirwa kuzivisa kuti ndeapi magadzirirwo akagadzirwa ane nhamba yepakati yematengesa makomba.
Chishandiso chakakosha mukuongorora maitiro ndeye X-ray muchina. X-rays ndeimwe yenzira dzekutsvaga dzenzizi uye dzinonyanya kubatsira paunenge uchibata nediki, dzakarongedzwa zvakarongedzwa PCBS. Kuve nemuchina wakareruka X-ray achaita kuti kuongororwa kuri kuita nyore zvakanyanya uye kunoshanda.
5.Roced Drilling Rate
Pamusoro pekuputira kweizvozvo, kumhanya kwekudhirowa kuchave nemhedzisiro yakakura pamhando yekutanga. Kana iyo yekumhanyisa yakanyanya kukwirira, ichaderedza chokwadi uye kuwedzera mukana wekuumbwa kwemarara. Kumhanya kwakanyanya kumhanya kunogona kutowedzera njodzi yePCB kuputsa, kutyisidzira kutendeka.
Kana maburi ari muCoating achiri kuzivikanwa mushure mekupinza kana kuchinja zvishoma, edza kudzora chiyero chekukwevera. Inononoka kumhanya inobvumira nguva yakawanda yekuumba, yakachena kuburikidza nemakomba.
Ramba uchifunga kuti nzira dzechinyakare dzinogadzira haisi sarudzo nhasi. Kana kushanda zvakanaka kufunga kwekutyaira yakakwira yekudhirowa, 3D kudhinda kunogona kunge kuri sarudzo yakanaka. 3D yakadhindwa PCBS yakagadzirwa zvakaringana pane nzira dzechinyakare, asi neyakafanana kana yakanyanya kukwana. Kusarudza 3 3D kwakadhindwa PCB kunogona kusada kudhira nemakomba zvachose.
6.Stk kune yakakwirira mhando mutengesi paste
Zviri muropa kuti uone nzira dzekuchengetedza mari muPCB yekugadzira maitiro. Nehurombo, kutenga zvakachipa kana-low-emhando yemushandirani paste inogona kuwedzera mukana wekuumba madhayeti weld.
Iyo yemakemikari zvivakwa zvemuterendekete akasiyana paste mhando dzinokanganisa kuita kwavo uye nenzira yavanobatanidza nePCB panguva yekuzorora. Semuenzaniso, uchishandisa mutengesi pasita iyo isina kutungamira inogona kuderera panguva yekutonhora.
Kusarudza yemhando yepamusoro mutengesi pasita inoda kuti iwe unzwisise zvinodiwa zvePCB uye template inoshandiswa. Varindi vekare pasita vanozooma kuti vapinde mukati meglate ine diki kuparadzwa.
Inogona kunge ichishandiswa kuyedza dzakasiyana-siyana mutengesi pastes panguva imwe chete sekuyedza akasiyana matemplates. Kusimbiswa kunoiswa pakushandisa iyo shanu-bhora mutemo kuti ugadzirise iyo template heprture saizi kuitira kuti mutengesi anyatsoenderana ne template. Mutemo unotaura kuti vagadziri vanoshandisa mafomu ekugadzira nemapepa anodikanwa kuti akwane madhiri mashanu emabhora eStte. Pfungwa iyi yakarerutsa maitiro ekugadzira akasiyana emagetsi emagetsi emagetsi ekuedzwa.
7.Retuce mutengesi paste oxidation
Oxidation yemutengesi pasita kazhinji inowanzoitika kana paine mhepo yakawandisa kana kunyorova munzvimbo yekugadzira. Oxidation pachayo inowedzera mukana weVOIDS inoumba, uye zvakare inopawo kuti mweya wakawandisa kana kunyorova kunowedzera kuwedzera njodzi yeVOIDS. Kugadzirisa uye kuderedza oxidation kunobatsira kudzivirira mazwi kubva pakugadzira uye kunovandudza PCB mhando.
Kutanga tarisa mhando yemutengesi pasita yakashandiswa. Mutengesi ane mvura-yemvura pasita anonyanya kufarirwa oxidation. Uye zvakare, isina kukwana flux inowedzera njodzi ye oxidation. Ehe, zvakawandisa flux iri zvakare dambudziko, saka vagadziri vanofanirwa kuwana chiyero. Nekudaro, kana oxidation ikaitika, ichiwedzera huwandu hwemvura inogona kuwanzogadzirisa dambudziko.
PCB Vagadziri vanogona kutora matanho mazhinji ekudzivirira kubhadhara uye kusimbisa maburi pane zvigadzirwa zvemagetsi. VOIDS dzinokanganisa kuvimbika, kuita uye hunhu. Neraki, kuderedza mukana wekuumbwa kweVOIDDS kuri nyore sekushandura mutengesi pasita kana kushandisa dhizaini itsva stencil.
Uchishandisa iyo bvunzo-yekuongorora nzira, chero mugadziri anogona kuwana uye kugadzirisa iyo inokonzeresa midzi yeVOIDS mu Reflux uye Pleting maitiro.
