Farta Dahabka PCBA Daabacan Golaha Wareega Wareegga

Sharaxaad Gaaban:

Soo saarista guddiga farta dahabiga ah ee PCB waa geedi socod muhiim ah, iyo habka wax soo saarka ee faahfaahsan ayaa lagu bixiyaa hoos: Diyaarinta walxaha: Dooro qalab tayo sare leh, sida FR-4 fiber fiber, si loo hubiyo xooggeeda farsamada iyo kuleylka kuleylka.Isla mar ahaantaana, dooro walxo bir ah oo leh koronto wanaagsan si aad u sameyso faraha dahabka ah.Naqshadeynta iyo qaabeynta: Nakhshadeynta guddiga PCB iyo qaabeynta iyadoo loo eegayo baahiyaha macaamiisha.Hubi in qaabka wareegga uu yahay mid macquul ah, dariiqa calaamaduhu waa siman yahay, oo ka tag meel nashqada qaybta farta dahabka ah.

Kalsoonida Sare

Photoplate: Isticmaalka tignoolajiyada sawir-qaadista si loogu wareejiyo qaababka wareegga dhulka hoostiisa.Walxaha naxaasta ah ee xad-dhaafka ah waxaa meesha ka saaraya sawir-maskaxeed iyo kiimiko etching si loo sameeyo qaabka wareegga la doonayo.Daawaynta dahabiga ah: Daawaynta dahabiga ah ayaa lagu sameeyaa qaybta farta dahabka si loo hagaajiyo dhaqdhaqaaqa korantada iyo caabbinta daxalka.Caadi ahaan, habka korantada waxaa loo isticmaalaa in si isku mid ah loogu dhejiyo walxaha birta ah ee dusha sare ee farta dahabka.Alxanka iyo isku-ururinta: Alxanka iyo isu geynta qaybaha iyo guddiga PCB si loo hubiyo in kala-goysyada alxanka ay yihiin kuwo adag oo la isku halayn karo.Isticmaal tignoolajiyada dulsaarka dusha sare (SMT) ama tignoolajiyada alxanka, dooro si waafaqsan shuruudo gaar ah.Kormeerka tayada iyo tijaabinta: Kormeerka tayada adag iyo tijaabinta ayaa la sameeyaa inta lagu jiro habka wax soo saarka si loo hubiyo in guddiga PCB ee farta dahabiga ah uu buuxiyo shuruudaha iyo tayada tayada.

Habaynta dabacsan

Oo ay ku jiraan kormeerka aragga, tijaabada sifada korantada, tijaabada ciribtirka xidhiidhka, iwm. Nadiifinta iyo dahaarka: Nadiifi PCB-ga Goldfinger ee dhammaatay si aad uga saarto wasakh iyo hadhaaga dusha sare.Daaweynta daahan ka-hortagga dahaadhka ayaa loo fuliyaa sida loogu baahan yahay si loo hagaajiyo caabbinta daxalka ee guddiga PCB.Baakadaha iyo keenista: Si sax ah u xidh PCB-ga Farta Dahabka ah ee la dhammaystiray si looga hortago dhaawac jidheed ama wasakhaysan.Ka dib markaad dhamaystirto kormeerka ugu dambeeya, u gaarsii macmiilka waqtigii loogu talagalay.Habka wax soo saarka guddiga PCB Goldfinger wuxuu u baahan yahay saxnaanta sare iyo koontarool adag si loo hubiyo tayada badeecada iyo xasilloonida.Waxaan u shaqayn doonaa si adag si waafaqsan nidaamka kor ku xusan si ay kuu siiyaan alaabta guddiga PCB far dahab ah oo tayo sare leh.
