4 Layer ENIG RO4003+AD255 Mixed Lamination PCB
RO4003C Rogers High Frequency PCB Zvishandiso
Iyo RO4003C zvinhu zvinogona kubviswa neyakajairwa naironi bhurashi.Hapana yakakosha kubata inodiwa pamberi pe electroplating mhangura isina magetsi.Iyo ndiro inofanirwa kurapwa uchishandisa yakajairwa epoxy/girazi maitiro.Kazhinji, hazvidiwi kubvisa chibhorani nekuti yakakwira TG resin system (280°C+[536°F]) haibudisi ruvara zviri nyore panguva yekuchera.Kana ruvara ruchikonzerwa nekuchera kwehasha, resin inogona kubviswa uchishandisa yakajairwa CF4/O2 plasma cycle kana ne dual alkaline permanganate process.
Iyo RO4003C zvinhu zvemukati zvinogona kunge zvakagadzirirwa uye / kana kemikari kugadzirira mwenje kudzivirira.Inokurudzirwa kushandisa yakajairwa aqueous kana semi-aqueous photoresists.Chero ipi neipi inotengeswa yemhangura wiper inogona kushandiswa.Ese anogona kusefa kana mapikicha anotengeswa masiki anowanzo shandiswa epoxy/girazi laminates anonamira zvakanyanya kumusoro kwero4003C.Mechanical kucheneswa kwenzvimbo dzakafumurwa dielectric kusati kwaiswa masks ekushivirira uye yakasarudzika "yakanyoreswa" nzvimbo inodzivirira kunamira kwakaringana.
Zvinodiwa zvekubika zvero4000 zvinhu zvakaenzana neaya epoxy/girazi.Kazhinji, midziyo isingabiki epoxy / girazi ndiro haidi kubika ro4003 ndiro.Kuisa epoxy/yakabikwa girazi sechikamu chemaitiro akajairika, tinokurudzira kubika pa 300 ° F, 250 ° f (121 ° c-149 ° C) kwe1 kusvika maawa maviri.Ro4003C haina chinodzimisa moto.Zvinogona kunzwisiswa kuti ndiro yakaputirwa mu infrared (IR) unit kana kushanda pamhepo yakaderera zvikuru yekufambisa inogona kusvika kune tembiricha inopfuura 700 ° f (371 ° C);Ro4003C inogona kutanga kupisa pane idzi tembiricha dzakakwirira.Masisitimu achiri kushandisa infrared reflux zvishandiso kana zvimwe midziyo inogona kusvika kune iyi tembiricha yepamusoro inofanirwa kutora matanho anodiwa kuona kuti hapana njodzi.
High-frequency laminates inogona kuchengetwa nekusingaperi mukamuri yekushisa (55-85 ° F, 13-30 ° C), humidity.Pakupisa kwekamuri, dielectric zvinhu zvine inert pane yakakwirira humidity.Nekudaro, machira esimbi akadai semhangura anogona oxidize kana akaiswa kune yakakwira humidity.Yakajairwa pre-kucheneswa kwePCBS inogona nyore kubvisa ngura kubva kune zvakachengetwa zvinhu zvakachengetwa.
Iyo RO4003C zvinhu zvinogona kugadzirwa uchishandisa maturusi anowanzo shandiswa epoxy/girazi uye yakaoma simbi mamiriro.Iyo foil yemhangura inofanirwa kubviswa kubva mugwara regwara kudzivirira kuzora.
