Nzira yekunyatsosarudza zvinhu zvePCB uye zvinhu zvemagetsi

Kusarudzwa kwezvinhu zvePCB uye zvigadzirwa zvemagetsi zvakadzidzwa, nekuti vatengi vanofanirwa kufunga nezve zvimwe zvinhu, senge maratidziro ekuita kwezvikamu, mabasa, uye mhando uye giredhi rezvikamu.

Nhasi, isu ticharatidza zvakarongeka sei kusarudza nemazvo PCB zvinhu uye zvemagetsi zvinoriumba.

Kusarudzwa kwezvinhu zvePCB

FR4 epoxy fiberglass wipes anoshandiswa kune zvigadzirwa zvemagetsi, polyimide fiberglass wipes anoshandiswa kune yakakwira ambient tembiricha kana flexible circuit board, uye polytetrafluoroethylene fiberglass wipes inodiwa kune yakakwirira-frequency maseketi. Kune zvigadzirwa zvemagetsi zvine zvinodiwa zvakanyanya kupisa kupisa, simbi substrates inofanira kushandiswa.

Zvinhu zvinofanirwa kutariswa pakusarudza PCB zvinhu:

(1) A substrate ine yakakwirira girazi tembiricha tembiricha (Tg) inofanira kusarudzwa zvakakodzera, uye Tg inofanira kunge yakakwira kupfuura tembiricha yekushanda yedunhu.

(2) Low coefficient of thermal expansion (CTE) inodiwa. Nekuda kwekusawirirana kweiyo coefficient yekuwedzera kwemafuta munzira yeX, Y uye ukobvu, zviri nyore kukonzera PCB deformation, uye zvinokonzeresa kutsemuka kwegomba uye kukuvadza zvikamu mumatambudziko akakomba.

(3) Kupisa kwakanyanya kunodiwa. Kazhinji, PCB inodiwa kuve nekupisa kwe250 ℃ / 50S.

(4) Kupfava kwakanaka kunodiwa. Iyo PCB warpage inodiwa yeSMT ndeye <0.0075mm/mm.

(5) Panyaya yekushanda kwemagetsi, high frequency circuits inoda kusarudzwa kwezvinhu zvine high dielectric constant uye yakaderera dielectric kurasikirwa. Insulation kuramba, voltage simba, arc kuramba kusangana nezvinodiwa zvechigadzirwa.

Kusarudzwa kwezvinhu zvemagetsi

Mukuwedzera pakusangana nezvinodiwa zvekushanda kwemagetsi, kusarudzwa kwezvikamu kunofanirawo kusangana nezvinodiwa zvekusangana kwepamusoro kune zvikamu. Asi zvakare zvinoenderana neyakagadzirwa mutsara wemidziyo mamiriro uye maitiro echigadzirwa kusarudza chikamu chekurongedza fomu, saizi yechikamu, chikamu chekurongedza fomu.

Semuenzaniso, apo gungano repamusoro-soro rinoda kusarudzwa kwezvikamu zvidiki-diki-diki: kana muchina wekusimudza usina yakakura-saizi braid feeder, iyo SMD mudziyo we braid packaging haigone kusarudzwa;
