Kana zvasvika kuPCB board prototyping, kusarudza iyo chaiyo zvinhu kwakakosha. Zvishandiso zvinoshandiswa muPCB prototypes zvinogona kuita zvakakosha pakuita, kuvimbika, uye kusimba kwechigadzirwa chekupedzisira.Mune ino blog positi, isu tichaongorora mamwe anonyanya kushandiswa PCB bhodhi prototyping zvinhu uye kukurukura zvakanakira nekuipira kwavo.
1.FR4:
FR4 ndiyo inonyanya kushandiswa zvinhu zvePCB board prototyping. Iyo girazi-yakasimbiswa epoxy laminate inozivikanwa nekunaka kwayo magetsi ekudzivirira zvinhu. FR4 zvakare ine yakakwira kupisa kuramba, ichiita kuti ive yakakodzera kune maapplication anoda yakanyanya-tembiricha kuita.
Imwe yemabhenefiti makuru eFR4 imari-inoshanda. Izvo zvakachipa zvichienzaniswa nezvimwe zvinhu pamusika. Pamusoro pezvo, FR4 ine yakanaka mechaniki kugadzikana uye inogona kumira yakakwira nhanho yekushushikana pasina kukanganisa kana kutyora.
Nekudaro, FR4 ine zvimwe zvinogumira. Iyo haina kukodzera kune maapplication anoda yakakwira frequency kuita nekuda kweiyo yakakwira dielectric kugara. Pamusoro pezvo, FR4 haina kukodzera zvikumbiro zvinoda yakaderera kurasikirwa tangent kana yakasimba impedance control.
2. Rogers:
Rogers Corporation imwe yakakurumbira sarudzo yePCB board prototyping. Rogers zvinhu zvinozivikanwa nepamusoro-inoshanda zvivakwa, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa, zvinosanganisira aerospace, telecommunication uye maindasitiri emotokari.
Zvishandiso zveRogers zvine zvakanakisa zvemagetsi zvivakwa, zvinosanganisira yakaderera dielectric kurasikirwa, yakaderera chiratidzo kukanganisa uye yakanyanya kupisa conductivity. Ivo zvakare vane yakanaka dimensional kugadzikana uye vanogona kushingirira mamiriro ezvakatipoteredza.
Nekudaro, iyo yakanyanya kusarudzika yeRogers zvinhu mutengo wavo wakakwira. Zvishandiso zveRogers zvinodhura zvakanyanya kupfuura FR4, inogona kuve inomisa chinhu pane mamwe mapurojekiti.
3. Metal core:
Metal Core PCB (MCPCB) imhando yakakosha yePCB board prototype inoshandisa simbi musimboti pane epoxy kana FR4 seyo substrate. Iyo yesimbi musimboti inopa yakanakisa kupisa kupisa, ichiita MCPCB yakakodzera zvikumbiro zvinoda maLED-simba makuru kana masimba emagetsi emagetsi.
MCPCB inowanzoshandiswa muindasitiri yemwenje, indasitiri yemotokari uye indasitiri yemagetsi emagetsi. Ivo vanopa zvirinani kupisa manejimendi zvichienzaniswa neyechinyakare maPCB, nekudaro vachiwedzera kuvimbika kwese uye hupenyu hurefu hwechigadzirwa.
Zvakadaro, MCPCB ine zvimwe zvayakaipira. Iwo anodhura kupfuura echinyakare maPCB, uye iyo simbi musimboti yakanyanya kuoma muchina panguva yekugadzira. Pamusoro pezvo, MCPCB ine kushomeka kuchinjika uye haina kukodzera kune maapplication anoda kukotama kana kumonyoroka.
Pamusoro pezvinhu zvataurwa pamusoro apa, kune zvimwe zvinhu zvehunyanzvi zvinowanikwa kune chaiwo maapplication. Semuyenzaniso, inochinjika PCB inoshandisa polyimide kana polyester firimu sehwaro zvinhu, izvo zvinobvumira PCB kukotama kana kuchinjika. Ceramic PCB inoshandisa ceramic zvinhu se substrate, ine yakanakisa yekupisa conductivity uye yakakwirira-frequency kuita.
Muchidimbu, kusarudza iyo chaiyo zvinhu zvePCB board prototype yako yakakosha kuti uwane kuita kwakaringana, kuvimbika, uye kusimba. FR4, Rogers, uye simbi musimboti zvinhu ndedzimwe sarudzo dzakajairika, imwe neimwe iine zvayakanakira nezvayakaipira. Funga nezve izvo chaizvo zvinodikanwa zvepurojekiti yako uye bvunza nenyanzvi PCB inogadzira kuti uone zvakanakisa zvekushandisa zvePCB prototype yako.
