Looxyada wareegyada kala duwan ayaa guud ahaan lagu qeexaa inay yihiin 10-20 ama in ka badan oo heer sare ah loox wareegyo kala duwan, kuwaas oo ay adag tahay in la habeeyo marka loo eego looxyada wareegyada multilayer dhaqameed oo u baahan tayo sare iyo adag.Inta badan waxaa loo isticmaalaa qalabka isgaarsiinta, server-yada ugu sarreeya, qalabka elektiroonigga ah ee caafimaadka, duulista, kontoroolka warshadaha, militariga iyo qaybaha kale.Sanadihii la soo dhaafay, baahida suuqa ee looxyada wareegyada lakabyada badan ee dhinacyada isgaarsiinta, saldhigyada saldhigyada, duulista, iyo militariga ayaa wali ah mid xoogan.
Marka la barbar dhigo alaabada PCB-ga caadiga ah, looxyada wareegyada lakabka badan waxay leeyihiin sifooyinka looxa dhumuc weyn, lakabyo badan, xariijimo cufan, in badan oo dalool ah, cabbirka cutubka weyn, iyo lakabka dielectric khafiif ah.Shuruudaha galmoodka ayaa sarreeya.Warqadani waxay si kooban u qeexaysaa dhibaatooyinka habka ugu muhiimsan ee ay la kulmeen soo saarista guddiyada wareegga heer-sare, waxayna soo bandhigaysaa qodobbada muhiimka ah ee xakamaynta hababka wax-soo-saarka muhiimka ah ee looxyada wareegyada badan.
1.Dhibaatada isku toosinta lakabka dhexdooda
Sababtoo ah tirada badan ee lakabyada ee guddiga wareegyada lakabyada badan, isticmaalayaashu waxay leeyihiin shuruudo sare oo sarreeya oo loogu talagalay hagaajinta lakabyada PCB.Caadi ahaan, isu-dheellitirka u dhexeeya lakabyada waxaa lagu maamulaa 75 microns.Iyadoo la tixgelinayo cabbirka weyn ee cutubka wareegga wareegga-lakabka badan, heerkulka sare iyo qoyaanka ku jira aqoon-is-weydaarsiga beddelka sawirada, kala-baxa kala-baxa ee ay sababtay is-waafajinta looxyada asaasiga ah ee kala duwan, iyo habka meelaynta interlayer, xakamaynta dhexe ee lakabka badan. looxa wareegga waa ka sii adag yahay.
Gudida wareegyada Multilayer
2. Dhibaatooyinka soo saarista wareegyada gudaha
Looxyada wareegyada Multilayer waxay isticmaalaan qalab gaar ah sida TG sare, xawaaraha sare, soo noqnoqda sare, copper qaro weyn, iyo lakabyo dielectric khafiif ah, kuwaas oo soo bandhigay shuruudaha sare ee wax soo saarka wareegga gudaha iyo xakamaynta cabbirka garaafyada.Tusaale ahaan, daacadnimada gudbinta calaamadaha impedance waxay ku kordhinaysaa adkaanta abuuritaanka wareegga gudaha.
Balladhka iyo kala dheeraynta xariiqdu waa yar tahay, wareegyo furan iyo kuwo gaaban ayaa lagu daraa, wareegyo gaaban ayaa lagu daray, heerka gudbintu waa yar yahay;waxaa jira lakabyo badan oo calaamado ah oo khadadka khafiifka ah, iyo suurtogalnimada in la ogaado daadinta AOI ee lakabka gudaha ayaa kordhay;looxa xudunta u ah waa dhuuban, fududahay in la laalaabto, soo bandhigid liidata, iyo si sahlan loo duuduubo marka mishiinka wax lagu xoqo;Taarikada heerka sare ah ayaa inta badan ah looxyada nidaamka, cabbirka cutubku waa weyn yahay, qiimaha qashinka alaabada ayaa sarreeya.
3. Caqabadaha ku jira soo saarista cufnaanta
Looxyo badan oo xudunta u ah iyo looxyada prepreg-ga ayaa la kor saaray, kuwaas oo si fudud u soo bandhigaya faa'iido darrada silbashada, delamination, resin voids iyo haraaga xumbo ee soo saarista shaambada.Naqshadeynta qaabka laminateerka, caabbinta kulaylka, caabbinta cadaadiska, nuxurka xabagta iyo dhumucda dielectric ee alaabta waa in si buuxda loo tixgeliyo, iyo qorshe macquul ah oo qalab wareeg ah oo qalabaysan waa in la sameeyaa.
Sababtoo ah tirada badan ee lakabyada, xakamaynta balaadhinta iyo foosha iyo magdhowga xajmiga xajmiga ma ilaalin karo joogteynta, iyo lakabka khafiifka ah ee khafiifka ah ee khafiifka ah waa mid fudud, taas oo horseedaysa fashilka tijaabada isku-kalsoonaanta interlayer.
4.Dhibaatooyinka soosaarka qodista
Isticmaalka TG sare, xawaaraha sare, soo noqnoqoshada sare, iyo naxaasta dhumucdiisuna waxay kordhisaa dhibka qodida qallafsanaanta, daloolista burooyinka iyo wasakhaynta.Tirada lakabyadu waa weyn yihiin, wadarta dhumucda naxaasta iyo dhumucda saxanka ayaa la ururiyey, iyo qalabka qodista waa sahlan tahay in la jebiyo;dhibaatada CAF ee fashilka ee ay sababtay BGA-da cufan ee loo qaybiyey iyo kala dheeraynta derbiga godka dhuuban;dhibka qodista qasabka ah ee ay sababtay dhumucda saxanka fudud.guddiga wareegga PCB
