Chii chinokonzera solder kuramba ruvara kuPCB?

Iyo PCB bhodhi haisi iyo yakanyanya kupenya, inonyanya kubatsira.

Chaizvoizvo, iyo ruvara rwePCB bhodhi pamusoro iruvara rwe solder mask.Kutanga, iyo solder inopikisa inogona kudzivirira kukanganisa kusina kunaka kwezvikamu.Chechipiri, inogona kunonoka hupenyu hwebasa remidziyo, kuitira kudzivirira oxidation uye corrosion yedunhu.

Kana iwe uchiziva zvakawanda nezvePCB board yeHUAWEI, Ericsson uye mamwe makambani makuru, iwe uchaona kuti ruvara runowanzo girini.Nekuti girinhi ruvara tekinoroji yePCB board ndiyo yakanyanya kukura uye yakapusa.

Kunze kwegirinhi, kune akawanda mavara ePCB, akadai se: chena, yero, dzvuku, bhuruu, sub light color, uye kunyange chrysanthemum, yepepuru, dema, yakasvibira yakasvibirira, etc. Muchena ndiyo pigment inodiwa pakugadzirwa kwemarambi uye mwenje.Kushandiswa kwemamwe mavara kunonyanya kuitirwa chinangwa chekunyora zvigadzirwa.Iyo PCB inogadzira zvigadzirwa zvekambani kubva kuR&D kusvika pakukura kwechikamu chose, zvinoenderana nekushandiswa kwakasiyana kwePCB board, bhodhi rekuyedza rinogona kushandisa yepepuru, kiyi bhodhi ichashandisa tsvuku, komputa yemukati bhodhi ichashandisa dema, ese ari kusiyanisa uye kutara neruvara.

Iyo inonyanya kuzivikanwa PCB igirini bhodhi, inozivikanwawo semafuta egirini, uye solder yayo kuramba inki ine nhoroondo refu, yakachipa uye inonyanya kufarirwa.Oiri yegirini ine zvakawanda zvakanaka kunze kwehunyanzvi hwekukura:

MuPCB kugadzirisa, kugadzirwa kwezvinhu zvemagetsi kunosanganisira kugadzira ndiro uye lamination.Munguva iyi, pane akati wandei maitiro ekupinda mukati yeyero mwenje kamuri, uye yakasvibira PCB board ine yakanakisa yekuona maitiro muyero mwenje kamuri.Chechipiri, mubhodhi reSMT PCB, nhanho dzetinning, lamination neAOI verification zvese zvinoda kugadzikwa kwemaziso uye kuenzanisa, uye PCB yegirinhi iri nani mukuzivikanwa kwechimbo.

Chikamu chemaitiro ekuongorora zvinoenderana nekutarisa kwevashandi (ikozvino vazhinji vavo vanoshandisa kubhururuka tsono bvunzo pachinzvimbo chebasa remaoko).Vanoramba vakatarisa pabhodhi pasi pechiedza chakasimba, uye kukuvara kwegirinhi kumaziso kwakaderera.Iyo yakasvibirira PCB bhodhi inonyanya kushamwaridzana nharaunda, uye mushure mekushisa kwakanyanya kudzokorodza, haizobudise magasi ane muchetura.

Mamwe mavara ePCB, akadai sebhuruu uye dema akaiswa cobalt uye kabhoni zvichiteerana.Nekuda kweavo vasina kusimba conductive, pane njodzi yepfupi dunhu.

Zvakadai sebhodhi dema, zvinonyanya kukonzeresa mutsauko wemuvara nekuda kwemaitiro uye matambudziko ezvakagadzirwa mukugadzira, izvo zvinotungamira kune yakakwira PCB chirema.Iyo nzira yebhodhi redunhu dema haisi nyore kuziva, izvo zvichawedzera kuoma kwekugadzirisa gare gare uye kugadzirisa.Naizvozvo, vakawandaPCB gungano vagadzirihaana kushandisa dema PCB board.Kunyangwe mumunda weindasitiri yemauto uye kutonga kwemaindasitiri, zvigadzirwa zvine mhando yepamusoro zvinodiwa zvinoshandisawo green PCB board.

Chii chinokonzera solder kuramba inki ruvara paPCB board?

Kune zvigadzirwa zvakapedzwa, kukanganisa kweingi dzakasiyana pabhodhi kunonyanya kuratidzwa mukuonekwa.Semuenzaniso, girini yegirini inosanganisira zuva rakasvibira, rakajeka girini, rima rakasvibira, rakasvibira matte uye zvichingodaro.Kana iyo ruvara rwakanyanya kujeka, Mushure meiyo plug hole process, kutaridzika kwebhodhi kuchave pachena.Vamwe vagadziri vane ingi dzisina kunaka, resin uye dhayi reshiyo matambudziko, uye pachave nemabhuru uye mamwe matambudziko Ona kudiki kuchinja kwemavara.Kune zvigadzirwa zvehafu-zvakapera, kukanganisa kunonyanya kuratidzwa muhuwandu hwekuoma mukugadzira.Mibvunzo iyi yakatinetsa kutsanangura.Iwo akasiyana mavara ingi ane akasiyana mavara maitiro, anosanganisira electrostatic spraying, spraying uye screen kudhinda, uye ingi reshiyo zvakare akasiyana.Kana paine chikanganiso chidiki, ruvara ruchaenda zvisirizvo.

Kunyangwe iyo ingi ruvara haina pesvedzero paPCB board, iyo inki ukobvu ine simba guru pane impedance.Kunyanya kumvura yegoridhe bhodhi, inodzora ukobvu hweinki zvakanyanya.Ingi dzvuku, ukobvu uye mabhuru zviri nyore kudzora, uye ingi tsvuku inogona kuvhara zvimwe zvakakanganiswa padunhu, izvo zviri nani pakuonekwa, asi chakashata ndechekuti mutengo unodhura.Paunenge uchifungidzira, zvitsvuku uye zvitsvuku zvakasvibiswa zvakanyanya kugadzikana, uye chena ndiyo yakaipisisa kudzora.

Muchidimbu, ruvara haruna pesvedzero pakuita kwebhodhi rakapedzwa, uye rine simba shoma paSMT PCBbhodhi uye zvimwe zvinongedzo.MuPCB dhizaini, kunyatso kudzora zvese mune imwe neimwe link ndiyo kiyi kune yakanaka PCB board.Mavara akasiyana ePCB board, kunyanya kutaridzika kuri nani kwechigadzirwa, isu hatikurudzire ruvara sechinhu chakakosha muPCB kugadzirisa.
