Kurongwa kwe substrates
General akadhindwa bhodhi substrate zvinhu zvinogona kupatsanurwa muzvikamu zviviri: rigid substrate zvinhu uye flexible substrate zvinhu.Rudzi rwakakosha rweyakaomesesa substrate zvinhu ndeye copper clad laminate.Yakagadzirwa neReinforeing Material, yakanamirwa neresin binder, yakaomeswa, yakachekwa uye yakanyungudutswa isina chinhu, yobva yafukidzwa nemhangura foil, uchishandisa simbi pepa seforoma, uye inogadziriswa nekushisa kwakanyanya uye kudzvanywa kwepamusoro mumuchina unopisa.General multilayer semi-cured sheet, yakashongedzwa nemhangura mukugadzirwa kwehafu-yakapera zvigadzirwa (kazhinji girazi jira rakanyikwa muresin, kuburikidza nekuomeswa kwekugadzirisa).
Kune nzira dzakasiyana dzekuisa mhangura dzakapfeka laminate.Kazhinji, zvichienderana neyakasiyana yekusimbisa zvinhu zvebhodhi, inogona kupatsanurwa muzvikamu zvishanu: bepa base, girazi fiber jira base, composite base (CEM akatevedzana), laminated multilayer board base uye yakakosha zvinhu base (ceramics, metal core base, etc.).Kana bhodhi rinoshandiswa zvakasiyana resin adhesives nokuda Classification, zvakajairika bepa - based CCI.Kune: phenolic resin (XPc, XxxPC, FR 1, FR 2, nezvimwewo), epoxy resin (FE 3), polyester resin uye mamwe marudzi.CCL yakajairika ndeye epoxy resin (FR-4, FR-5), inova ndiyo inonyanya kushandiswa mhando yegirazi fiber jira.Pamusoro pezvo, kune mamwe maresheni akakosha (girazi faibha jira, polyamide faibha, jira risiri rakarukwa, nezvimwewo, semidziyo yakawedzerwa) : bismaleimide yakagadziridzwa trizine resin (BT), polyimide resin (PI), diphenyl ether resin (PPO), maleic anhydride imide - styrene resin (MS), polycyanate ester resin, polyolefin resin, nezvimwe.
Zvinoenderana nekuita kweCCL kudzoreredza moto, inogona kukamurwa kuita murazvo unodzoreredza mhando (UL94-VO, UL94-V1) uye isiri-flame retardant mhando (Ul94-HB).Mumakore gumi nemaviri apfuura, sezvo zvakanyanya kubhadharwa kune kuchengetedzwa kwezvakatipoteredza, rudzi rutsva rweCCL-retardant CCL isina bromine yakaparadzaniswa, iyo inogona kunzi "green flame-retardant CCL".Nekukurumidza kusimudzira kwemagetsi chigadzirwa tekinoroji, cCL ine yepamusoro kuita zvinodiwa.Naizvozvo, kubva kuCCL performance classification, uye yakakamurwa kuita general performance CCL, yakaderera dielectric inogara CCL, yakanyanya kupisa kupisa CCL (general plate L mu150 ℃ pamusoro), yakaderera kupisa kwekuwedzera coefficient CCL (inowanzo shandiswa pakurongedza substrate) uye mamwe marudzi. .
Standard ye substrate kushandiswa
Nekuvandudzwa uye kuenderera mberi kwehunyanzvi hwemagetsi, zvinodiwa zvitsva zvinogara zvichiiswa pamberi pezvakadhindwa bhodhi substrate zvinhu, kuitira kusimudzira kuenderera mberi kwekusimudzirwa kwemhangura yakavharwa ndiro zviyero.Parizvino, iwo makuru zviyero zve substrate zvinhu ndeaya anotevera.
