4 Layeri ENIG RO4003 + AD255 Ivangavanga Kumurika PCB
RO4003C Rogers Ibikoresho Byinshi bya PCB Ibikoresho
Ibikoresho bya RO4003C birashobora gukurwaho hamwe na brush isanzwe ya nylon.Nta buryo bwihariye busabwa mbere yo gukwirakwiza umuringa udafite amashanyarazi.Isahani igomba kuvurwa hakoreshejwe epoxy isanzwe / ikirahure.Muri rusange, ntabwo ari ngombwa kuvanaho umwobo kuko sisitemu yo hejuru ya TG resin (280 ° C + [536 ° F]) idahinduka byoroshye mugihe cyo gucukura.Niba ikizinga cyatewe nigikorwa cyo gucukura bikaze, ibisigarira birashobora gukurwaho ukoresheje plasma isanzwe ya CF4 / O2 cyangwa nuburyo bubiri bwa alkaline permanganate.
Ubuso bwa RO4003C burashobora kuba muburyo bwa tekinike cyangwa / cyangwa muburyo bwa shimi kugirango burinde urumuri.Birasabwa gukoresha amafoto asanzwe yo mumazi cyangwa igice cyamazi.Ihanagura ry'umuringa iryo ariryo ryose rirashobora gukoreshwa.Byose byungururwa cyangwa bifotora masike isanzwe ikoreshwa kuri epoxy / ikirahure laminates ifata neza cyane hejuru ya ro4003C.Isuku yuburyo bwa dielectric igaragara mbere yo gukoresha masike yo gusudira hamwe nubutaka "bwanditse" bugomba kwirinda gufatana neza.
Ibisabwa byo guteka ibikoresho bya ro4000 bihwanye nibya epoxy / ikirahure.Mubisanzwe, ibikoresho bidateka epoxy / ibirahuri ntibikeneye guteka amasahani ya ro4003.Mugushiraho epoxy / ibirahuri bitetse mubice bisanzwe, turasaba guteka kuri 300 ° F, 250 ° f (121 ° c-149 ° C) mumasaha 1 kugeza 2.Ro4003C ntabwo irimo flame retardant.Birashobora kumvikana ko isahani ipakiye muri infragre (IR) cyangwa ikora ku muvuduko muke wohereza irashobora kugera ku bushyuhe burenze 700 ° f (371 ° C);Ro4003C irashobora gutangira gutwikwa kuri ubu bushyuhe bwo hejuru.Sisitemu igikoresha ibikoresho bya infrarafurike cyangwa ibindi bikoresho bishobora kugera kuri ubu bushyuhe bwo hejuru bigomba gufata ingamba zikenewe kugirango hatabaho ingaruka.
Laminates yumurongo mwinshi irashobora kubikwa ubuziraherezo mubushyuhe bwicyumba (55-85 ° F, 13-30 ° C), ubushuhe.Ku bushyuhe bwicyumba, ibikoresho bya dielectric byinjizwa mubushuhe bwinshi.Nyamara, gutwikira ibyuma nkumuringa birashobora okiside iyo bihuye nubushyuhe bwinshi.Isuku mbere yo gusukura PCBS irashobora gukuraho byoroshye ruswa mubikoresho bibitswe neza.
Ibikoresho bya RO4003C birashobora gutunganywa hakoreshejwe ibikoresho bisanzwe bikoreshwa muri epoxy / ikirahure hamwe nicyuma gikomeye.Umuringa wumuringa ugomba gukurwa kumuyoboro uyobora kugirango wirinde gusiga.
