Ndeupi chiyero chekusarudza zvikamu uye zvinhu pakuungana PCB?

PCB gungano rekugadzirisa rinosanganisira rakadhindwa redunhu dhizaini, PCB prototyping,SMT PCB bhodhi, chikamu chekutsvaga uye mamwe maitiro.Saka, ndedzipi PCBA bhodhi yekugadzirisa zvikamu uye substrate sarudzo zviyero?

1. Kusarudzwa kwezvikamu

Kusarudzwa kwezvikamu kunofanirwa kutora nhoroondo yakazara yenzvimbo chaiyo yeSMB, uye zvikamu zvakajairika zvinofanira kusarudzwa sezvinobvira.Izvo zvidiki-saizi zvikamu hazvifanirwe kuteedzerwa neupofu kudzivirira kuwedzera mutengo.IC zvishandiso zvinofanirwa kucherechedza kuti iyo pini chimiro uye pini spacing;QFP ine isingasviki 0.5mm pini spacing inofanira kutariswa nekuchenjera, unogona kushandisa zvakananga BGA package.

Uye zvakare, iyo yekurongedza fomu yezvikamu, solderability yePCB, kuvimbika kweSMT PCB musangano, uye tembiricha inotakura huwandu hunofanirwa kuverengerwa.Mushure mekusarudza zvikamu, dhatabhesi yezvikamu zvinofanirwa kusimbiswa, kusanganisira saizi yekuisa, saizi yepini uye SMT mugadziri uye imwe data yakakodzera.

2.Kusarudzwa kwezvinhu zvekutanga zvePCB

Iyo yekutanga zvinhu ichasarudzwa zvinoenderana nemamiriro ebasa eSMB uye zvinodiwa zvemakanika nemagetsi kuita.Nhamba yemhangura yakavharwa foil nzvimbo (imwechete, kaviri kana yakawanda-layer) ye substrate inotarirwa maererano neSMB chimiro;ukobvu hweiyo substrate inotarwa zvichienderana nehukuru hweSMB uye mhando yezvikamu pachikamu cheyuniti.Paunosarudza maSMB substrates, zvinhu zvakaita sezvinodiwa zvemagetsi, kukosha kweTg (tembiricha yegirazi), CTE, flatness uye mutengo nezvimwe… zvinofanirwa kutariswa.

Zviri pamusoro ndiyo pfupiso pfupi yegungano rebhodhi redunhu rakadhindwakugadzirisa zvikamu uye substrate sarudzo zviyero.Kuti uwane rumwe ruzivo, unogona kushanya zvakananga kune yedu webhusaiti: www.pcbfuture.com kuti udzidze zvakawanda!
