4 Lakabka ENIG RO4003+AD255 Lamination Mixed PCB
RO4003C Rogers Qalabka PCB ee Joogtada Sare
Walaxda RO4003C waxa lagu saari karaa burushka naylon ee caadiga ah.Ma jirto wax ka qabasho gaar ah oo loo baahan yahay ka hor inta aan korantada la gelin korantada.Saxanka waa in lagu daaweeyaa habka epoxy/glaas ee caadiga ah.Guud ahaan, muhiim maaha in meesha laga saaro godka riigga sababtoo ah habka sare ee TG resin system (280°C+[536°F]) si fudud uma midabbo inta lagu jiro habka qodista.Haddii wasakhdu ay keento hawlgal qodis ah oo gardarro ah, xabagta waxaa laga saari karaa iyadoo la isticmaalayo wareegga balaasmaha caadiga ah ee CF4/O2 ama habka laba alkaliin ee permanganate.
Maaddada RO4003C waxa laga yaabaa in si farsamaysan iyo/ama kiimiko ahaan loo diyaariyey ilaalinta iftiinka.Waxaa lagu talinayaa in la isticmaalo photoresists caadiga ah aqueous ama semi-aqueous.Maxaasta tirsiga naxaasta ah ee ganacsi ahaan loo heli karo waa la isticmaali karaa.Dhammaan maaskaro la miiran karo ama sawir lagu iibin karo oo caadi ahaan loo isticmaalo lakabyada epoxy/glass waxay si fiican ugu dheggan yihiin dusha ro4003C.Nadiifinta makaanikada ee dusha sare ee dielectric ka hor inta aan la isticmaalin waji-xidhka alxanka iyo sagxadaha "diiwaangashan" ee loo qoondeeyay waa in ay ka fogaato ku dhegganaanta ugu wanaagsan.
Shuruudaha karinta ee alaabta ro4000 waxay u dhigantaa kuwa epoxy/glaas ah.Guud ahaan, qalabka aan karinin epoxy/glass uma baahna inuu karsado taarikada ro4003.Ku rakibida epoxy/muraayadaha la dubay oo qayb ka ah habka caadiga ah, waxaanu ku talinaynaa in lagu kariyo 300°F, 250°f (121°c-149°C) ilaa 1 ilaa 2 saacadood.Ro4003C kuma jiro ololka celinaya.Waxaa la fahmi karaa in saxan ku jira unug infrared (IR) ama ku shaqeeya xawli aad u hooseeya uu gaari karo heerkul ka badan 700°F (371°C);Ro4003C wuxuu ku bilaabi karaa gubashada heerkulkan sarreeya.Nidaamyada weli isticmaala aaladaha reflux infrared ama qalabka kale ee gaari kara heerkulkan sare waa inay qaadaan taxadarka lagama maarmaanka ah si loo hubiyo inaysan jirin khatar.
Laminatesyada soo noqnoqda ee sarreeya waxaa lagu kaydin karaa si aan xad lahayn heerkulka qolka (55-85F, 13-30°C), qoyaan.Heerkulka qolka, agabka dielectric ayaa ah kuwo aan firfircoonayn oo qoyaan badan.Si kastaba ha ahaatee, dahaarka biraha ah sida naxaasku waxay oksidhiye karaan marka ay la kulmaan qoyaan badan.Nadiifinta caadiga ah ee PCBS waxay si fudud uga saari kartaa daxalka alaabta sida habboon loo kaydiyay.
Qalabka RO4003C waxaa lagu farsamayn karaa iyadoo la isticmaalayo qalab caadi ahaan loo isticmaalo epoxy/ galaas iyo xaaladaha biraha adag.Foornada naxaasta ah waa in laga saaraa kanaalka haga si looga hortago in la xoqdo.
