Mukuita kudzidza zvemagetsi, isu tinowanzoona 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 (Nekuburikidza negomba / via), kudzivirira inki yekupinza (Solder resistant / Solder Mask), kudhinda screen (Legend/Maka/Silk screen. ), Surface kurapwa, Surface Finish), nezvimwe.
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, izvo zvikamu uye wiring yekubatanidza senge transistors, resistors, capacitors uye inductors inodiwa mudunhu inogadzirwa pachidimbu chidiki kana akati wandei zvidimbu zve semiconductor chip kana dielectric substrate yobva yavharirwa mugoko kuti ive microstructure. nemabasa edunhu anodiwa. 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.
