Kubva kuPCB World,
Vanhu vazhinji vanoshandisa ruvara rwePCB kusiyanisa kunaka kwebhodhi.Muchokwadi, ruvara rwebhodhi reamai harine chekuita nekuita kwePCB.
PCB board, kwete kuti iyo yakakwirira kukosha, zviri nyore kushandisa.
Rudzi rwePCB pamusoro irwo ruvara rweiyo solder kuramba.Iyo solder inopikisa inogona kudzivirira kuitika kwekukanganisa kwekutengesa kwezvikamu, uye kunonoka hupenyu hwebasa remudziyo, uye kudzivirira oxidation uye corrosion yedunhu remudziyo.
Kana iwe ukanzwisisa PCB mabhodhi emakambani makuru akadai seHuawei neZTE, uchaona kuti ruvara runowanzo girini.Izvi zvinodaro nekuti tekinoroji yakasvibira ndiyo yakanyanya kukura uye yakapusa.
Mukuwedzera kune yakasvibirira, ruvara rwePCB runogona kurondedzerwa se "mabhero nemhete": chena, yero, tsvuku, bhuruu, matte mavara, uye kunyange chrysanthemum, yepepuru, yakasviba, yakasvibirira yakasvibirira, etc. Kuvapo kwechena, nokuti iyo zvinodiwa kugadzira zvigadzirwa zvekuvhenekesa Mavara anoshandiswa, uye kushandiswa kwemamwe mavara, anonyanya kunyorerwa zvigadzirwa.Muchikamu chese chekambani kubva kuR&D kusvika pakugadzika kwechigadzirwa, zvichienderana nekushandiswa kwakasiyana kwePCB, bhodhi rekuyedza rinogona kunge riri repepuru, kiyi bhodhi ichave dzvuku, uye mabhodhi emukati ekombuta achave madema, ayo akanyorwa. neruvara.
Iyo inonyanya kuzivikanwa PCB board ndiyo green green board, inonziwo green oil.Iyo solder mask inki ndiyo yekare, yakachipa uye inonyanya kufarirwa.Kuwedzera kune tekinoroji yakakura, mafuta egirinhi ane zvakawanda zvakanakira:
Mukugadzirisa PCB, kugadzirwa kwezvigadzirwa zvemagetsi kunosanganisira kugadzira bhodhi uye kupeta.Munguva yemaitiro, kune akati wandei maitiro ekupinda mukati yeyero light room, uye yegirinhi PCB board ine yakanakisa kuona mukamuri yeyero;chechipiri, mu SMT chigamba kugadzirisa, tini inoiswa.Matanho e, patching uye AOI calibration zvese zvinoda optical positioning calibration, uye chiridzwa chegirini chepasi chine hushamwari pakuziva.
Chikamu chechirongwa chekuongorora chinovimba nevashandi kuti vatarise (asi iye zvino vazhinji vavo vanoshandisa kuongorora kubhururuka panzvimbo yebhuku rekushandisa), vakatarisa pabhodhi pasi pechiedza chakasimba, girini ine hushamwari kumaziso.Green PCBs zvakare ane hushamwari hwezvakatipoteredza, uye haasunungure magasi ane muchetura kana achishandiswa patsva tembiricha.
Mamwe mavara ePCB, akadai sebhuruu uye dema, anoiswa cobalt uye kabhoni, zvichiteerana, nekuti ane hutera hwemagetsi conductivity, uye kune njodzi yekupfupika kwedunhu.
Tora bhodhi dema semuenzaniso.Mukugadzira, bhodhi dema rinonyanya kukonzeresa mutsauko wemavara nekuda kwemaitiro uye mbishi matambudziko, zvichikonzera yakakwira PCB chirema.Izvo zvinongororwa zvebhodhi redunhu dema hazvisi nyore kusiyanisa, izvo zvichawedzera kuoma kwekugadzirisa gare gare uye kugadzirisa.Mafekitari mazhinji ePCB haashandise maPCB matema.Kunyangwe muminda yeindasitiri yemauto uye kutonga kwemaindasitiri, zvigadzirwa zvine yakanyanyisa mhando zvinodiwa zvinoshandisa green PCB substrates.

Tevere, ngatitaure nezve mhedzisiro ye solder mask inki ruvara pabhodhi?
Nokuda kwechigadzirwa chakapedzwa, mhedzisiro yeingi dzakasiyana pabhodhi inonyanya kuratidzwa mukuonekwa, ndiko kuti, kana yakanaka kana kwete.Semuenzaniso, girini inosanganisira zuva rakasvibirira, rakasvibira rakasvibira, rima rakasvibira, matt girini, nezvimwewo, ruvara rwakanyanya kupenya, zviri nyore kuona plug Kuonekwa kwebhodhi mushure megomba maitiro asina kunaka, uye vamwe vanogadzira ' ingi hadzina kunaka, resin uye dhayi reshiyo inonetsa, pachava nezvinetso zvakaita semabhubhu, uye kudiki kuchinja kwemavara kunogonawo kuonekwa;kukanganiswa kwezvigadzirwa zvehafu-zvakapera zvinonyanya kuratidzwa Maererano nekuoma kwekugadzirwa, dambudziko iri rakati kuoma kutsanangura.Ingi dzakasiyana dzemavara dzine maitiro akasiyana ekuisa mavara, senge electrostatic spraying, spraying, uye screen kudhinda.Iyo inki reshiyo zvakare yakasiyana.Kukanganisa kudiki kuchaita kuti ruvara ruoneke.dambudziko.
Kunyange zvazvo ruvara rweinki rusina zvarunoita pabhodhi rePCB, ukobvu hweinki hune simba guru pane iyo impedance, kunyanya yebhodhi yemvura-yegoridhe, iyo ine simba rakanyanyisa kudzora ukuru hweinki;hupamhi uye mabhubhu einki tsvuku zviri nyore kudzora, uye inki tsvuku inovhara Pamutsara, zvimwe zvikanganiso zvinogona kuvharwa, uye chitarisiko chakanyanya kunaka, asi chakaipa ndechekuti mutengo unodhura.Paunenge uchifungidzira, tsvuku uye yellow exposures zvakanyanya kugadzikana, uye chena ndiyo yakanyanya kuoma kudzora.

Kupfupisa, ruvara haruna mhedzisiro pakuita kwebhodhi rakapedzwa, uye rine zvishoma zvishoma pamusangano wePCB uye mamwe malink;muPCB dhizaini, zvese mune yega link inodzorwa, uye PCB board inova Kiyi yebhodhi yakanaka.PCB mamaboards emavara akasiyana anonyanya kutengesa zvigadzirwa.Hazvikurudzirwe kuti ushandise ruvara sechinhu chakakosha kufunga muPCB kugadzirisa.
