Mukuita kudzidza zvemagetsi, isu tinowanzo ziva yakadhindwa redunhu bhodhi (PCB) uye Integrated circuit (IC), vanhu vazhinji "vanovhiringika" nezvepfungwa mbiri idzi. Muchokwadi, hazvisi izvo zvakaoma, nhasi tichajekesa mutsauko pakati pePCB nedunhu rakasanganiswa.
Chii chinonzi PCB?
Yakadhindwa Circuit Board, inozivikanwawo sePrinted Circuit Board muchiChinese, chikamu chakakosha chemagetsi, chikamu chetsigiro chezvikamu zvemagetsi uye mutakuri wemagetsi ekubatanidza zvinhu zvemagetsi. Nemhaka yokuti yakagadzirwa nekudhinda kwemagetsi, inonzi "yakadhindwa" bhodhi redunhu.
Irizvino redunhu bhodhi, rinonyanya kuumbwa mutsara uye Surface (Pattern), Dielectric layer (Dielectric), gomba (Kuburikidza negomba / via), kudzivirira welding inki (Solder resistant/Solder Mask), screen printing (Legend/Marking/Silk screen), Surface treatment, Surface Finish), nezvimwewo.
Zvakanakira PCB: high density, high kuvimbika, designability, producibility, testability, assemblability, maintainability.
Chii chinonzi dunhu rakasanganiswa?
Iyo yakabatanidzwa yedunhu chinhu chidiki chemagetsi mudziyo kana chikamu. Uchishandisa imwe nzira, zvikamu uye wiring interconnection senge transistors, resistors, capacitors uye inductors inodiwa mudenderedzwa inogadzirwa pachidimbu chiduku kana zvidimbu zviduku zvishoma zve semiconductor chip kana dielectric substrate uye zvino yakavharidzirwa muhombodo kuti ive microstructure ine mabasa anodiwa edunhu. Zvose zvezvikamu zvakave zvakabatanidzwa, zvichiita kuti zvikamu zvemagetsi zvive danho guru kune miniaturization, kushandiswa kwesimba shoma, njere, uye kuvimbika kwakanyanya. Inomiririrwa nebhii “IC” mudunhu.
Zvinoenderana nebasa uye chimiro chedunhu rakabatanidzwa, rinogona kukamurwa kuita analog yakasanganiswa maseketi, dhijitari yakabatanidzwa dunhu uye dijitari / analogi yakasanganiswa yakabatanidzwa dunhu.
Dunhu rakabatanidzwa rine zvakanakira saizi diki, huremu, waya shoma inotungamira, uye welding point, hupenyu hurefu, kuvimbika kwepamusoro, kuita kwakanaka, nezvimwe.
Hukama pakati pePCB nedunhu rakasanganiswa.
Iyo yakabatanidzwa yedunhu inowanzo kunzi iyo chip yekubatanidza, senge bhodhi reamai paNorthbridge chip, CPU yemukati, inonzi Integrated Circuit, zita rekutanga rinonzi zvakare Integrated block. Uye PCB ibhodhi redunhu isu tinowanzo kuzviziva uye rakadhindwa pane redunhu bhodhi welding machipisi.
Iyo yakabatanidzwa yedunhu (IC) inosungirirwa kuPCB board. PCB board ndiyo inotakura yedunhu rakasanganiswa (IC).
Mukutaura kwakapfava, dunhu rakasanganiswa idunhu rakazara rakasanganiswa mune chip, iyo yakazara. Kana ichinge yakuvadzwa mukati, iyo chip ichakuvadzwa. PCB inogona weld zvikamu zvega, uye zvikamu zvinogona kutsiviwa kana zvakatyoka.
