Shenzhen Chengyuan Industrial Automation Equipment Co, Ltd inopa mhinduro dzehunyanzvi uye otomatiki michina yeSMT yakangwara fekitori mitsara yekugadzira.
SMT mounter, lead-isina reflow soldering, lead-isina wave soldering, PCB conformal pendi yekuisa muchina, muchina wekudhinda, yekurapa oveni.
Hapana mubvunzo kuti iyo yakadhindwa yedunhu bhodhi (PCB) chishandiso chakakosha muhunyanzvi hwevanhu.
MaPCB ave nzira yekugonesa magadzirirwo ekugadzirwa kwezvinhu zvemagetsi.Kare, magetsi aya akagadzirwa nemaoko aifanira kutsiviwa nemabhodhi edunhu akadhindwa.Izvi zvinodaro nekuti mamwe mabasa achabatanidzwa pabhodhi.
Enzanisa bhodhi redunhu rekarukureta ra1968 nebhodhi rekombuta yemazuva ano.
1. Ruvara.
Kunyangwe kune vamwe vanhu vasingazivi kuti PCB ndeyei, vanowanzoziva kuti PCB inotaridzika sei.Vanotaridzika kunge vane imwe tsika yechinyakare, iyo yakasvibira.Iyi girini ndiyo chaiyo yakajeka ruvara rwe solder mask girazi pendi.Kunyangwe zita reiyo solder mask iri solder mask, basa rayo guru nderekudzivirira dunhu rakavharwa kubva kune hunyoro neguruva.
Nekuda kwekuti sei solder mask yakasvibira, chikonzero chikuru ndechekuti girinhi ndiyo chiyero chekudzivirira chemauto.Kekutanga, maPCB mumidziyo yemauto akashandisa masikisi ekutengesa mumunda kuchengetedza kuvimbika kwedunhu.
Solder masks ave kuwanikwa mune akasiyana mavara, anosanganisira dema, tsvuku, yero, nezvimwe.Mushure mezvose, girini haisi chiyero cheindasitiri.
2. Ndiani akagadzira PCB?
Mapuranga ekutanga akadhindwa edunhu anogona kuteverwa kumashure kune injiniya wekuAustria Charles Ducas muna 1920, uyo akaronga pfungwa yekuitisa magetsi neingi (kudhinda waya dzendarira pandiro yepasi).Akashandisa tekinoroji ye electroplating kugadzira waya zvakananga pamusoro peiyo insulator uye akaita PCB prototype.
Waya dzesimbi pamapuranga edunhu pakutanga dzaive ndarira, alloy yemhangura uye zinc.Ichi chinovhiringidza chigadzirwa chinobvisa iyo yakaoma wiring process yemagetsi maseketi, kuve nechokwadi chekuvimbika kwekuita kwedunhu.Iyi nzira haina kupinda muchikamu chekushandisa kusvika mushure mekupera kweHondo Yenyika II.
3. Maka.
Pane zvakawanda zvemavara machena pagirinhi redunhu bhodhi.Kwemakore, vanhu vaisanzwisisa kuti sei mavara machena aya ainzi "silkscreen layers".Ivo vanonyanya kushandiswa kuona chikamu ruzivo padunhu bhodhi uye zvimwe zvirimo zvine chekuita nebhodhi redunhu.Ruzivo urwu runogona kubatsira mainjiniya edunhu kutarisa bhodhi pane zvikanganiso.
