PCB imhando yezvikamu zvemagetsi, zvakare inotakura iyo yese PCBA, zvimwe zvikamu zvemagetsi zvakaiswa paPCB pad, tamba yavo yemagetsi kutaurirana basa.
Chigamba chinofanira kushandiswa PCB.PCB mukugadzira kunze kweyakajairwa ndeye vacuum kurongedza, munetora uye isa muchinachigamba pamberi kudiwa pcb kubika?
Kunyanya kubheka kune inotevera welding kuchava nani.
Zvinotora nguva yakareba sei kubika PCB?
Inoda kugoverwa maererano nePCB yekuchengetedza nguva.
Kune PCB iyo yakachengetwa kwemwedzi 1-2, kubika kweinenge 1 awa inowanzokwana.
Kuchengetwa kwePCB isingasviki mwedzi mitanhatu, kubheka kwakawanda kwemaawa maviri kunogona kuva.
Kuchengetedzwa kweanopfuura mwedzi mitanhatu, mwedzi gumi nemaviri pazasi pcb, general kubika anenge maawa mana.
Kupfuura 12 mwedzi yekuchengetedza nguva, kazhinji inokurudzirwa kusashandisa.
Ndeipi tembiricha yakakodzera yekubikira?
Kubika tembiricha musimboti pa120 ℃, nekuti chinangwa chekubika ndechekubvisa unyoro, chero bedzi kupfuura tembiricha yekubuda kwemhute yemvura inogona kuva, kazhinji 105 ℃ kusvika 110 ℃ inogona kuva.
Sei kubika, pasina kubika kuchaunza njodzi ipi?
Sei PCB kubika, ndiko kubvisa unyoro uye hunyoro.Nokuti PCB iri multilayer bhodhi laminated pamwe chete, kuchengetwa zvakasikwa kwezvakatipoteredza pachava yakawanda mvura mhute, mvura mhute achabatanidzwa pamusoro pepamusoro pcb kana kuchera kupinda mukati.
Kana isina kubikwa, mhute yemvura mukatireflow ovensoldering kukurumidza kudziya, mvura mhute inosvika 100 ℃, iyo inobereka yakawanda yekusimudzira, kana isina kubviswa panguva yakakodzera, inogona pcb inoputika kana kukuvadza kune yemukati wedunhu, zvichikonzera kupfupika kwedunhu kana kunotevera kushandiswa kwemaitiro ematambudziko akashata.
PCB yekubheka inofanira kuiswa sei?
Kazhinji mutete uye hombe saizi pcb hazvikurudzirwi kuisa vertical, nokuti zviri nyore mukubika kupisa kuwedzera uye ipapo kutonhora kutonhora shrinkage, zvichiita micro-deformation.
Mabhodhi madiki anokurudzirwa kuti aturikire, asi zviri nani kuti usaturikidze zvakanyanya, kudzivirira pcb kubika mukati memhute yemvura haisi nyore kubuda.
Zvinyorwa paPCB kubika
Mushure mekubika PCB, mukugadzirisa kutonhora kunofanira kuiswa apo uremu hwekumanikidza kudzivirira micro-deformation.
pcb hovhoni inofanira kugadzikwa mukati memudziyo wekupeta kudzivirira kubuda kwemwando kubva muchoto hakugone kuburitswa.
