Misiyano Yakakosha Pakati peAluminium neFR4 PCBs

Mabhodhi edunhu akadhindwa anoumba mitsipa yemidziyo yemagetsi yemazuva ano, ine maPCB eAluminium neFR4 PCB ari maviri emhando dzinonyanya kushandiswa. Ose ane hunhu hwakasiyana uye anoshandiswa mumashandisirwo akasiyana. Chinyorwa chino chinotsvaga kukubatsira kujekesa mutsauko uripo pakati peAluminium neFR4 PCB , zvichikubatsira pakusarudza paunenge uchitanga chirongwa chitsva chemagetsi.

Material Kuumbwa

Aluminium PCBs: Inoratidzira simbi yepakati, inowanzo gadzirwa nealuminium kana aruminiyamu alloy. Iyi musimboti inopa yakanakisa kupisa kupisa, ichiita kuti ive yakanaka kune yekupisa manejimendi mune yakanyanya-kupisa application.
FR4 PCBs: Yakagadzirwa negirazi faibha-yakasimbiswa epoxy resin, ichipa yakanaka magetsi ekudzivirira uye simba remuchina. Iyo "FR" muFR4 inomirira Flame Retardant, inosangana neUL 94V-0 zvinodiwa.

Kuchengetedza Kwemhepo

Aluminium PCBs: Dada yakakwira yekupisa conductivity, kuendesa zvinobudirira uye kubvisa kupisa. Hunhu uhu hwakakosha kune maapplication akadai LED chiedza uye magetsi emagetsi.
FR4 PCBs: Iva nekushomeka kwemafuta ekupisa zvichienzaniswa neAluminium PCBs, zvichiita kuti dzisakodzere kukwirisa-tembiricha yekushandisa.

Mechanical Simba uye Rigidity

Aluminium PCBs: Ratidza yakakura simba remuchina uye kusimba nekuda kwesimbi yepakati base. Ivo havanyanyi kuita warping, zvichiita kuti ive yakakodzera kune yakasimba applications.
FR4 PCBs: Ipa yakanaka mechani simba asi inogona kuve yakanyanya brittle kana ichienzaniswa neAluminium PCBs.

Zvinokosha Mutengo

Aluminium PCBs: Kazhinji inodhura zvakanyanya nekuda kwemitengo yakakwira yezvinhu uye maitiro akaomarara ekugadzira.
FR4 PCBs: Inodhura-inoshanda, inowanikwa zvakanyanya, uye inoshanda zvakasiyana-siyana, zvichiita kuti ive sarudzo yakakurumbira kune akasiyana siyana maapplication.

Mashandisirwo Emashandisirwo

Aluminium PCBs: Inonyanya kushandiswa mune yakakwirira-simba maapplication senge LED mwenje, mota dzemagetsi, uye emagetsi mamodule nekuda kwehukuru hwekugona kutonga kwekupisa.
FR4 PCBs: Yakasiyana-siyana uye inokodzera kuwanda kwemagetsi, kunyanya uko yakanyanya kupisa conductivity isiri iyo inonyanya kunetseka.

Layering uye Ukobvu

Aluminium PCBs: Kazhinji inoumba matatu akaturikidzana, anosanganisira aluminium substrate, copper conductive layer, uye dielectric layer. Iwo anowanzo kuganhurirwa maererano nechiyero chekuverenga uye ukobvu nekuda kwehukuru hweiyo dielectric kana inotsigira simbi layer.

FR4 PCBs: Inogona kusiyanisa kubva kune imwechete-layer kusvika kune akawanda-layer masisitimu, ichipa kuchinjika kukuru mukugadzira uye ukobvu. Izvi zvinoita kuti FR4 PCBs ikwane kune yakafara mhando yemagetsi maapplication, kunyanya panosiyana bhodhi ukobvu kunodiwa.

Kuwedzera Kwekupisa

Aluminium PCBs: Iva neakaderera coefficient of thermal expansion (CTR) kana ichienzaniswa neFR4, iri pedyo neCTR yemhangura. Ichi chivakwa chinodzikisira njodzi yekuwedzera-ane hukama nenyaya muPCB, sekutyora mumitsara yemhangura uye maburi ane simbi.
FR4 PCBs: Iva neCTR yakakwirira, iyo inogona kutungamirira kumatambudziko nekuwedzera kwekushisa, kukanganisa kuvimbika kwebhodhi mune mamwe maitiro.

Sarudzo pakati peAluminium PCBs uye FR4 PCBs inotsamira pane izvo chaizvo zvinodiwa zvekushandisa kwako. Aluminium PCBs anokunda mumamiriro ezvinhu anoda kupisa kupisa kwakanaka uye kusimba, senge mune yakakwirira-simba maLED application uye mota dzemagetsi. Kune rimwe divi, FR4 PCBs isarudzo inochinja-chinja uye inodhura-yemhando yakawanda yezvigadzirwa zvemagetsi, kunyanya uko kutonga kwekupisa kusiri kunonyanya kunetseka. Kunzwisisa misiyano iyi kwakakosha pakugadzirisa mashandiro uye kuvimbika kwemapurojekiti ako emagetsi.
