The Printed redunhu bhodhi (pcb) rakakamurwa Single madziro Boards , Double-mativi Boards uye Multi-rukoko Boards.
The wokutanga Single madziro Boards, pamusoro inokosha pcb, umo nhengo dziri pfungwa kudivi uye tambo iri other.Because ari waya ndiyo chete rumwe rutivi, kunonzi Single-kuzviitirwa Boards, ari Single madziro mapuranga zvinowanzova nyore kuti uye risinganyanyi cost, asi zvakaipira ndechokuti haigoni kushandisirwa chakaoma zvigadzirwa.
The Boards Double-mativi chinhu kuwedzera Single madziro Boards, uye kana chimwe rukoko wiring haagoni zvidikanwi electronic chigadzirwa, Double-mativi Boards vari used.Both kumativi akafukidzwa mhangura waya, uye anogona neseri gomba kutungamirira mutsetse pakati maviri akaturikidzana kuitira kuumba runodiwa zvakarukwa papi.
Multi-rukoko Boards ari kudhindwa ndiro rine akaturikidzana matatu conductive hwakajeka rukoko uye insulating mashoko pakati, uye conductive girafu iri interlinked maererano requirement.The multilayer redunhu bhodhi iri zvakagadzirwa kukura zvigadzirwa mashoko yepamusoro soro Kasira, multi-basa, makuru vanokwanisa, vhoriyamu duku, dzakaonda mhando uye chiedza uremu.
Maererano unhu, yakadhindwa redunhu bhodhi rakakamurwa kusanduka bhodhi (FPC) , vanachandagwinyira bhodhi (pcb) , flexi uye vanachandagwinyira bhodhi (FPCB).
The akadhindwa redunhu mapuranga Anonyanyowanika riine nomoto Mapedhi, makomba, vanomhanyisa mumakomba, waya, zvinoriumba, connectors, fillers, zvemagetsi nemiganhu, etc.
The chikuru mabasa neimwe rokuti ndeinotevera:
Welding ikanyanya: mumwe PTH buri inoshandiswa Welding mbambo muzvinhu zvikuru zvinoriumba.
Kuburikidza buri: PTH kuburikidza mugomba uye NPTH kuburikidza mugomba, kuti PTH kuburikidza buri inoshandiswa kubatanidza zvinoumba pakati zvinoriumba.
Kubhururuka makomba: kushandiswa wakaiswa kudhindwa vematunhu mapuranga.
Waya: zvemagetsi rezvebonde mhangura firimu inoshandiswa kubatanidza nembambo zvinoriumba.
Connector: chimwe chezvinonhuwira inoshandiswa unobatanidza wakadhindwa redunhu bhodhi.
Fillers: mhangura rinoshandisirwa pasi waya pomumbure anogona zvinobudirira kuderedza impedance.
Electrical muganhu: kushandiswa kuona ukuru akadhindwa redunhu bhodhi, uye hapana zvinoumba pamusoro rakadhindwa redunhu bhodhi anogona kusapfuudza muganhu.
Muchidimbu, yakadhindwa redunhu bhodhi chawo zvinhu kunyanya zvinosanganisira zvitatu zvikuru mbishi zvinhu zvakadai mhangura foil, nebwe, uye anowedzera zvinhu.
FR-4 vanowanzochema mashoko akadhindwa redunhu bhodhi (PCBs), uye ane mamakisi akawanda uye mhando dzakadai TG130, TG150, High TG 170 uye 180 nezvimwewo, vakawanda akadhindwa redunhu mapuranga anogadzirwa kushandisa girazi-Akazadzisa epoxy laminate sezvo substrate, apo pane zvakasiyana-siyana laminates pa pamisika, FR-4 zvose-chinja uye zvakanaka kugamuchirwa sechiero mashoko pcb gadzira . FR-4 mabasa zvakanaka somunhu zvemagetsi insulator, uye ane zvakanaka simba-kuti-uremu reshiyo, uye ari murazvo nemishonga.
Tiine kuwedzera kukwikwidzana pamisika, maererano nheyo " mukuru utariri , kunyatsoteerera zvaidiwa , yepamusoro , uye basa kugonesesa ", uye kushanda kwayo zvinobatsirawo kumusika, ano, uye matarenda, KingSong anopa vatengi hwedu hwakanakisisa uye vakatsanya zvinhu uye mabasa.
