Unoda kuti mudziyo wako ugare kwenguva yakareba, kunyangwe munzvimbo dzakaoma. Zvimwe zvinhu zvePCB zviri nani pane izvi. Zvinhu izvi zvinogona kubata kupisa, kushushikana, uye kukotama pasina kutyoka. Tafura iri pazasi inoratidza sarudzo dzakanakisa:
Material Type | Key Features | Best Applications |
|---|---|---|
MaLaminate eTg Akakwirira | Shanda pakupisa kwakanyanya (Tg 170°C+) | Zvemotokari, maindasitiri |
Zvinhu zveCTE Zvakaderera | Deredza kushushikana kwekupisa | Nzvimbo dzine shanduko huru dzetembiricha |
Polyimide | Kugadzikana kukuru kwekupisa uye kuchinjika | Zvishandiso zvinopfekwa, zvishandiso zvinopetwa |
Ceramic Substrates | Kugara kwenguva refu pasi pekumanikidzwa | Midziyo inoda mari yakawanda uye yakavimbika |
Cherechedza: Polyimide neceramic PCBs zvakanaka kune zvishandiso zvinopisa, zvinozununguka, kana zvinoda kukotama.
Kuenzanisa Zvinhu Zvose
Unofanira kufunga nezvemutengo, mashandiro, uye kuvimbika. Heano mamwe matipi:
Shandisa maPCB ane layer mbiri kuti uchengetedze mari uye uwane mhedzisiro yakanaka.
Ita shuwa kuti impedance inoenderana nezvinodiwa neprojekiti yako.
Sarudza FR-4 yemidziyo iri nyore kuti mitengo igare yakaderera.
Sarudza aruminiyamu kana ceramic kana mudziyo wako ukatanga kupisa.
Enzanisa simba remagetsi nezvinhu zvakakodzera. Semuenzaniso, shandisa FR-4 yesimba shoma, aruminiyamu yepakati, uye ceramic yesimba guru.
Edza dhizaini yako nekukurumidza kuti uwane matambudziko usati wavaka.
Gara uchitarisa kana zvinhu zvako zvichirwisa ngura uye zvichishanda munzvimbo yemudziyo wako.
Zano: Kumbira bvunzo dzemurabhoritari dzeIPC-A-600 kuti uve nechokwadi chekuti zvinhu zvako zvePCB zvakakunakira.
Kusarudza PCB yakakodzera kunobatsira kuti mudziyo wako ushande zviri nani uye ugare kwenguva refu. Chinhu chimwe nechimwe, senge FR-4, PTFE, kana polyimide, chine simba rakakosha. Izvi zvinobatsira nezviratidzo, kupisa, uye kuita kuti mudziyo wako uve wakasimba.
Gara uchisarudza zvinhu zvinoenderana nebasa remudziyo wako.
Kupera pamusoro pechinhu kunogona kubatsira kuti mudziyo wako ugare kwenguva refu.
Nyanzvi dzinoti unofanira kutarisa kuti zvinhu zvacho zvinobata sei magetsi, kushushikana, uye nharaunda usati wasarudza.
Device Device | Zvinhu Zvakanakisisa zvePCB |
|---|---|
smartphones | Dhizaini yeHDI ine machira akawanda, inokurumidza uye yakatetepa |
Wearables | Inochinjika, yakareruka, inopetwa |
zveindasitiri | Inogara kwenguva refu, inodzivirira nharaunda dzakaoma |
Kana purojekiti yako yakaoma, taura nenyanzvi dzePCBVanogona kukubatsira kuwana zvinhu zvakanakira mudziyo wako.
FAQ
Chii chinonzi kuderedzwa kwechiratidzo mumaPCB efoni?
Signal attenuation zvinoreva kuti chiratidzo chinodzikira pakufamba kwacho. Unoda kuti chiratidzo chisadzikire kana chikashandiswa nekukurumidza. Zvinhu zvePTFE neRogers zvinobatsira kudzivirira kuti chiratidzo chisadzikire. Izvi zvinoita kuti foni yako ishande zviri nani uye zvakavimbika.
Ndingasarudza sei zvinhu zvepakutanga zvePCB yangu yenharembozha?
Sarudza chinhu chakakodzera zvinodiwa nemudziyo wako. Funga nezvekuti ine simba rekudzikisa masaini akawanda sei. Zvakare, tarisa kana ichikwanisa kubata kupisa uye kuti inodhura zvakadii. Pamidziyo inokurumidza, shandisa zvinhu zvinoita kuti kudzikisa masaini kuve kwakaderera.
Sei kudzikiswa kwechiratidzo kuchikosha kune tekinoroji ye5g?
Tekinoroji ye5g inoda masaini anokurumidza uye akajeka. Kana kudzikiswa kwemasaini kwakakwira, mudziyo wako unogona kunonoka. Inogonawo kukanganisa. Shandisa zvinhu zvinoita kuti kudzikiswa kwemasaini kuve kwakaderera kuti uwane mhedzisiro yakanaka ye5g.
Ndezvipi zvinhu zvePCB zvinobatsira kuderedza kuderera kwechiratidzo zvakanyanya?
PTFE naRogers ndivo vanonyanya kuderedza kuderera kwesimba remasaini. Zvinhu izvi zvinochengetedza masaini akasimba uye akajeka. Zvishandise kana uchida kuti masaini asarasike zvakanyanya mumudziyo wako.
Kudzikira kwemasaini kunogona kukanganisa hupenyu hwebhatiri remudziyo wangu here?
Ehe, kudzikiswa kwemasaini kunogona kuita kuti mudziyo wako ushandise simba rakawanda. Kana kudzikiswa kwemasaini kwakakwira, mudziyo wako unoshanda nesimba kutumira masaini. Izvi zvinogona kuita kuti bhatiri rako rishande nekukurumidza. Sarudza zvinhu zvinoderedza kudzikiswa kwemasaini kuti bhatiri rako rigare kwenguva refu.
Zano: Gara uchitarisa kuti PCB yako ine kuderedzwa kwechiratidzo kwakadii usati wasarudza.
