Iwe unoona masere makuru dhizaini matanda mune PCB

Izvo zvakakosha kuti unzwisise uye kusiyanisa zvidimbu zvePCB. Kuti unzwisise zvirinyore ukobvu hwePCB, musiyano wakanaka unodiwa kuve nechokwadi chekuti pcb inoshanda pakunyanyisa kushanda. The following layers are typically seen in stacked PCBS. Izvi zvinogona kusiyana, zvichienderana nenhamba yezvikamu, dhizaini, uye dhizaini yacho pachayo.

L michini yakatenderera

Ichi ndicho chikamu chepakutanga chePCB. Iyo inoshandiswa seyekunze kwebhodhi redunhu. This is the basic physical framework of a PCB. Rukoko urwu runogonesawo mugadziri kuti ataure nzvimbo chaiyo yezvibhorani nekutemwa.

L chengeta musara

Rukoko urwu rwakafanana neyakagadzirwa michina pakuti inogona zvakare kushandiswa seyakakombama. Nekudaro, iro basa rerubatiro rwekutsikisa ndiko kutsanangura iko kwekuisa magetsi, wedunhu waya, nezvimwe. Hapana chinhu kana dunhu rinogona kuiswa kunze kwemuganhu uyu. Iyi nhete inoganhurira wiring yemidziyo yeCAD pamusoro penzvimbo dzakananga.

L routing rukoko

Iyo yekumisikidza rukoko inoshandiswa kubatanidza zvikamu. Aya marara anogona kuwanikwa kune chero mativi ebhodhi redunhu. Kuiswa kwematanho kuri kumugadziri, uyo anoita sarudzo zvichienderana nekushandisa uye zvinhu zvinoshandiswa.

L Ndege inodzikisira uye ndege yemagetsi

Aya matanda akakosha kune chaiyo kushanda kwePCB. Ground pasi uye kugoverwa kwenzvimbo pasi redunhu bhodhi uye zvikamu zvaro. Iyo sosi yemagetsi, kune rumwe rutivi, yakabatana kune imwe yematanho ari paPCB pachayo. Ose maviri akaturikidzana anogona kuoneka pamusoro, pasi, uye kutyora ndiro dzePCB.

L Kupatsanura ndege

Ndege yakakamurwa iri ndege yemagetsi yakakamurwa. Semuenzaniso, iyo ndege yemagetsi iri pabhodhi inogona kutsemurwa nepakati. Imwe hafu yendege yemagetsi inogona kubatanidzwa ku + 4V uye imwe hafu kusvika -4V. Nekudaro, zvikamu zviri pabhodhi zvinokwanisa kushanda nematanho maviri akasiyana zvichienderana nekubatana kwavo.

L Kuvhara / kutenderera screen

Iyo silkscreen layer inoshandiswa kuisa mamaki mamaki ezvinhu akaiswa pamusoro pebhodhi. Iyo yekufukidzira inoita basa rakafanana kunze kwekuzasi kweplate. Aya matanda anobatsira mukugadzira uye kugadzirisa dambudziko.

L nemishonga nomoto rukoko

Mhangura wiring uye kuburikidza-maburi pamabhodhi edunhu dzimwe nguva anonzi sekuvharidzira kwekudzivirira kwemasofa. Iyi dura inochengeta guruva, guruva, hunyoro uye zvimwe zvakatipoteredza zvinhu kubva pabhodhi.

L iyo yakasungirirwa pasita

Shandisa solder paste mushure megungano pamusoro pekumisikidza. Inobatsira kusanganisa zvikamu kudunhu redunhu. Iyo zvakare inofambisa yemahara kuyerera kweiyo solder mune pcb inoumbwa nepamusoro-yakasungirirwa zvikamu.

Ese aya marongedzo anogona kunge asipo mune imwechete-rukoko PCB. Aya maratidziro akavakirwa pane yakadhindwa wedunhu bhodhi dhizaini. Aya magadzirirwo akaturikidzana anobatsira kufungidzira huwandu hwakazara hwePCB kana imwe micron ukobvu ichiverengerwa. Idzi idzi ruzivo dzinokubatsira iwe kuti urambe wakaomarara kushivirira kunowanikwa mune mazhinji PCB mapurani.
