Indasitiri inodzora PCB FR4 yekuisa goridhe 26 akaturikidzana countersink

Iyo maindasitiri inodzora PCB ibhodhi rakadhindwa redunhu rinoshandiswa mumaindasitiri ekudzora masisitimu kutarisa uye kudzora akasiyana ma paramita akadai setembiricha, mwando, kudzvanywa, kumhanya, uye mamwe maitiro akasiyana.Aya maPCB anowanzo kuomeswa uye akagadzirirwa kumirisana nenzvimbo dzakaomarara dzemaindasitiri senge dzinowanikwa mukugadzira zvidyarwa, zvidyarwa zvemakemikari, uye michina yemaindasitiri.Maindasitiri anodzora maPCB anowanzo batanidza zvinhu zvakaita semamicroprocessors, programmable logic controllers (PLCs), masensa, uye ma actuators anobatsira kudzora nekugadzirisa maitiro akasiyana.Vanogonawo kusanganisira nzvimbo dzekutaurirana dzakadai seEthernet, CAN, kana RS-232 yekuchinjana data nemimwe michina.Kuve nechokwadi chekuvimbika kwepamusoro uye kuenderera mberi kwekushanda, maPCB anodzora maindasitiri anoedzwa kwakasimba uye matanho ekudzora mhando panguva yekugadzira kwavo uye kugadzira.Ivo vanofanirwa zvakare kutevedzera indasitiri zviyero seUL, CE, uye RoHS, pakati pevamwe.

High layers PCB ibhodhi redunhu rakadhindwa rine akawanda akaturikidzana emhangura yemhangura uye zvinhu zvemagetsi zvakaiswa pakati pawo.Vanowanzova nezvikamu zvinopfuura zvitanhatu uye zvinogona kukwira kusvika pamakumi mashanu kana kupfuura, zvichienderana nekuoma kwekugadzirwa kwedunhu.High layers PCBs dzinobatsira pakugadzira compact zvishandiso zvinoda huwandu hukuru hwezvikamu.Ivo vanobatsira kukwenenzvera kurongeka kwebhodhi redunhu nekufambisa makwara akaoma uye matani kuburikidza neakawanda akaturikidzana.Izvi zvinoguma mune imwe compact uye inoshanda dhizaini inochengetedza nzvimbo pabhodhi.Aya mabhodhi anowanzo shandiswa mumashandisirwo emagetsi epamusoro-soro, akadai seaerospace, kudzivirira, uye maindasitiri ekufonera.Vanoda hunyanzvi hwekugadzira epamberi, senge laser drilling uye inodzorwa impedance routing, kuve nechokwadi chepamusoro uye kuvimbika.Nekuda kwekuoma kwadzo, kugadzira nekugadzira zvidimbu zvePCB zvinogona kudhura uye kutora nguva kupfuura maPCB akajairwa.Pamusoro pezvo, iyo yakawanda maseru ine PCB, inokwirisa mukana wekukanganisa panguva yekugadzira nekugadzira.Nekuda kweizvozvo, akaturikidzana maPCB anoda kuyedzwa kwakakura uye matanho ekudzora emhando kuti ave nechokwadi chekushanda kwavo uye kuvimbika.

Countersink a PCB inoreva nzira yekuboora gomba mubhodhi uyezve kushandisa dhayamita hombe bhiti kugadzira conical recess yakatenderedza gomba.Izvi zvinowanzoitwa kana musoro wescrew kana bhaudhi uchida kupeperetswa nepamusoro pePCB.Countersink inowanzoitwa panguva yekuchera nhanho yekugadzira PCB, mushure mekunge mhangura yaiswa uye bhodhi risati rapfuura kuburikidza neanotengesa mask uye silkscreen kudhinda maitiro.Saizi uye chimiro chegomba rakanyura-yakanyura zvinoenderana nescuru kana bhaudhi riri kushandiswa uye ukobvu uye zvinhu zvePCB.Izvo zvakakosha kuve nechokwadi chekuti countersink kudzika uye dhayamita kwakakodzera kudzivirira kukuvadza zvikamu kana zviteshi paPCB.Countersink a PCB inogona kunge iri nzira inobatsira pakugadzira zvigadzirwa zvinoda nzvimbo yakachena uye yakati sandara.Iyo inobvumira screws uye mabhaudhi kuti agare akanyunguduka nebhodhi, achigadzira chitarisiko chinoyevedza uye kudzivirira snagging kana kukuvadzwa kubva kune zvinobatidza fasteners.
