Pcb maererano bhodhi chikumbiro kupatsanura chete Panel, kaviri Panel, multilayer pcb; Sekureva kweshoko, kune akaomarara pcb bhodhi (inochinjika bhodhi), akaomarara pcb bhodhi, kuomarara-anochinja-pcb bhodhi (akaomarara anochinja bhodhi), nezvimwe. Yakadhindwa Circuit Board (PCB), inozivikanwawo sePrinted Circuit Board, chinhu chakakosha chemagetsi, iboka rekutsigira remagetsi zvigadzirwa, ndiye anotengesa zvemagetsi zvigadzirwa zvemagetsi kubatana, nekuti inoitwa neyemagetsi kudhinda tekinoroji, saka zviri zvakare inonzi Printed Circuit Board. Pcb inongova ndiro yakatetepa ine maseketi akasanganiswa uye zvimwe zvigadzirwa zvemagetsi.

Kurongwa maererano nenhamba yematanho edunhu

Yakakamurwa kuita imwechete mapaneru, maviri mapaneru uye akawanda-masenduru bhodhi. Zvakajairika multilayer bhodhi kazhinji 3-6 akaturikidzana, uye yakaoma multilayer bhodhi inogona kusvika anopfuura gumi akaturikidzana.

(1) Imwe pani

Pane rakakosha rakadhindwa redunhu bhodhi, izvo zvikamu zvinoiswa kune rumwe rutivi uye waya dzakatariswa kune imwe. Nekuti iyo waya inoonekwa kudivi rimwe chete, rakadhindwa redunhu bhodhi inonzi rimwe chete pani. Masekete ekutanga aishandisa rudzi urwu rwebhodhi redunhu nekuti paive nezvirambidzo zvakaomarara padanho rekugadzira repaneru rimwe (nekuti paingova nedivi rimwe chete, wiring yaisakwanisa kuyambuka uye yaifanirwa kufambiswa neimwe nzira).

(2) Mapaneru maviri

Dunhu redunhu rine wiring pamativi ese maviri. Kuti tambo dzese pamativi ese dzikurukurirane, panofanirwa kunge paine kubatana kwedunhu kwakakodzera pakati pemativi maviri, ayo anonzi gomba rekutungamira. Makomba ekuperekedza makomba madiki mune rakadhindwa redunhu bhodhi, rakazadzwa kana kuputirwa nesimbi, ayo anogona kuve akabatana newaya pamativi ese. Mapaneru maviri anogona kushandiswa pamaseketi akaomesesa kupfuura mapaneru imwe nekuti iyo nzvimbo yakapetwa kaviri uye wiring inogona kupindirwa (inogona kukuvadzwa kune rimwe divi).

(3) Multilayer bhodhi

Kuti uwedzere nzvimbo iyo inogona kuve newired, akawanda-masenduru mabhodhi anoshandisa mamwechete kana maviri-mativi matambo wiring. Multilayer mabhodhi anoshandisa akati wandei mapaneru, uye anoisa inozvidzivirira nhete pakati pega yega bhodhi mushure mekubatana. Huwandu hwematanda pabhodhi hunomiririra akati wandei ezvikamu zvakazvimirira zvewiring, kazhinji kunyange akaenzana matanda, uye iine ekunze maviri akaturikidzana.

Piri, zvinoenderana nerudzi rweiyo substrate

Anochinjika wedunhu mabhodhi, akaomarara wedunhu mabhodhi uye akaomarara-anochinjika akasungwa mabhodhi.

(1) Zvichienderana pcb bhodhi (tefa bhodhi)

Anochinjika mabhodhi akadhindwa wedunhu mabhodhi akagadzirwa kubva anochinjika substrates, ayo ane mukana wekuve wakakombama kufambisa gungano remagetsi zvinhu. FPC yave ichishandiswa zvakanyanya muaerospace, mauto, nharembozha, makomputa anotakurika, zvigadzirwa zvemakomputa, PDA, kamera dzemadhijitari uye mimwe minda kana zvigadzirwa.

(2) Vanachandagwinyira pcb bhodhi

Yakagadzirwa nepepa base (inowanzo shandiswa kune rimwe divi) kana girazi jira base (inowanzo shandiswa kune maviri-mativi uye akawanda-masenduru), pre-akaiswa mushonga wepamuviri phenolic kana epoxy resin, rimwe kana mativi ese epasi akasungirirwa nemhangura pepa uye ipapo laminated kurapa. Rudzi urwu rwePCB mhangura-yakapfeka foil board, isu tinoriidza kuti rakaomarara bhodhi. Yakazogadzirwa kuita pcb, isu tinoidaidza kuti yakaoma PCB yakaomarara bhodhi haisi nyore kukotama, ine simba uye kuomarara kwechinhu chakaomarara chepasi chakagadzirwa nemabhodhi edunhu akadhinda, chakanakira icho ndechekuti inogona kusungirirwa kune zvemagetsi zvigadzirwa kupa kutsigirwa kwakati.

(3) Vanachandagwinyira-kusanduka pcb bhodhi (vanachandagwinyira-kusanduka pcb bhodhi)

Rigid–flexible bonded board rinoreva rakadhindwa redunhu bhodhi rine imwe kana anopfuura akaomarara uye anochinjika nzvimbo, anoumbwa akaomarara mabhodhi uye anochinjika mabhodhi akaomeswa pamwechete.
