Pcb bhodhi tsananguro yekugadzira:

Yakazara interconnect yemagetsi mamodule akadhindwa wedunhu bhodhi kana PCB. Iyo ine imwechete uye yakawanda inoshanda maseketi. Mahwendefa aya anogutsa kudiwa kwemagetsi michina uye maseketi. Pcb bhodhi ine inodzivirira zvinhu substrate pane iyo nhete nhete yekuitisa zvinhu yakaiswa. Dzakananga zvemagetsi zvinoriumba zvakaiswa panze pane inodzivirira zvinhu (substrate) yePCB uye zvakabatana kune interconnect redunhu nenzira inodziya uye inonamira. Izvo zvinogona zvakare kushandiswa seyakaenderana switchboards.

Vagadziri vanotarisirwa kuti vaparadzire chero zvikanganiso zvisina basa muhurongwa hwakarongwa. Kunyange zvakadaro, maitiro acho ari kuwedzera kusaenderana sezvo mamwe masangano achiburitsa zvikumbiro zvavo zvePBB kune vatengi vekunze.

Type:

Pcb inovaka inowira mumatatu makuru marudzi:

Imwe-mativi: Aya maPCBS ane nhete nhete yekupisa-kuitisa zvinhu uye nhete yemhangura yakaomeswa kuputira dialectics. Iyo yemagetsi yakabatana kune rumwe rutivi rweiyo substrate.

Yakapetwa kaviri: Mune ino pcb, zvimwe zvinhu zvinogona kuiswa pane substrate pane pane imwechete-mativi pcb.

Multilayer: Zvikamu pane iyo substrate zvakabatana nekuboora pasi mumakomba akasarudzika munzvimbo yakakodzera yedunhu. Huwandu hwe multilayer PCBS yakaiswa inodarika imwechete-mativi uye maviri-mativi PCBS. Inoita iyo patunhu yedunhu ive nyore.

Kune zvakare maviri marudzi: akasanganiswa maseketi (anozivikanwawo seamaic kana ma microchips) uye masystem masystem. Maitiro eIC akafanana nemamwe marudzi, asi aine mamwe macircuit akaiswa pamusoro penzvimbo diki yesilicon machipisi. Musiyano chete mumatunhu emahyidha ndewekuti izvo zvikamu zvinorimwa pamusoro pane kuiswa neanamatira.

Components:

Pane pcb board, chinhu chemagetsi chakaiswa pamusoro. Kune zvakare maitiro akasiyana siyana, akadai se:

Kuburikidza mugomba rwokugadzira:

Kwemakore mazhinji, kuburikidza-gomba tekinoroji rave richishandiswa kugadzira angangoita ese akadhindwa wedunhu mabhodhi (PCBS). Iyo yepakati-gomba chikamu chakaiswa nemaviri axial anotungamira. Kune simba rechimakanika, iwo anotungamira akakombama pane 90 degree Angle uye inotengeswa kune yakatarisana nedivi. Kuburikidza-gomba kukwira kunovimbika chaizvo sezvo ichipa yakasimba michini yekubatanidza; Nekudaro, iyo yekuwedzera kuchera yakaita kuti mabhodhi anodhura kugadzira.

Pamusoro kugomo tekinoroji:

SMT yakaderera pane yayo-kuburikidza-gomba shamwari. Izvi zvinodaro nekuti chinhu cheSMT chingave chine zvidiki zvinotungamira kana kusava nemutungamiri zvachose. Ndiyo kota kusvika kune yechitatu kuburikidza negomba. PCBS ine pamusoro pegomo zvishandiso (SMD) hazvidi kuchenesa kwakawanda, uye izvi zvinhu zvakanyatso nyongana, zvichibvumira kukwirira kwedunhu kuomarara pamabhodhi madiki.

Kubudikidza neyakanaka degree of otomatiki, mari yevashandi inoderedzwa uye kugadzirwa kunovandudzwa zvakanyanya.

Design:

Pcb bhodhi vagadziri vanoshandisa macomputer anobatsira kudhirowa (CAD) zvivakwa kugadzira maseketi sampuli pabhodhi. Mabasa akasarudzika anogoverwa kune chaiwo zvigadzirwa. Dare revatungamiriri rinofanirwa kuita iro basa, iro ravanogadza. Iyo nzvimbo pakati redunhu uye inoitisa nzira yakatetepa. Inowanzoita 0.04 inches (1.0 mm) kana pasi.

Icharatidzawo chinhu chinotungamira kana chekubata padhuze negomba, uye chinyorwa ichi chinoshandurwa kuita mirairo yeCNC yekuboora laptop kana tekinoroji yekugadzira inoshandiswa mune otomatiki waya yekunamatira.

Dhinda mufananidzo wakaremara kana chifukidzo kune saizi chaiyo papepa rakachena repurasitiki, semuenzaniso nekukurumidza mushure mekuratidza masampula edunhu. Kana iyo pikicha isina kunaka, iyo nharaunda inogona kunge isisiri yemuenzaniso chidimbu cheiyo dunhu ichagadzwa mutema uye iyo wedunhu pateni ichaedzwa seyakajeka.
