Rigid PCB vs. Flexible PCB: Ndeipi PCB mhando yakanakira application yako?

suma:

Munyika yekugadzira bhodhi redunhu, kusarudza mhando yePCB (Yakadhindwa Circuit Board) kwakakosha mukubudirira kweprojekiti yako yemagetsi.Sarudzo mbiri dzakakurumbira dzinotonga indasitiri dzakaomarara uye dzinochinjika maPCB.Rudzi rwega rwega rune mabhenefiti akasiyana uye mafungidziro anoita kuti kuita sarudzo kunetse kune vanhu vazhinji.Mune ino blog, isu tichakurukura zvakanakira nezvazvakaipira zvemhando mbiri dzePCB kuti ikubatsire kuita sarudzo ine ruzivo.Semutambi anovimbwa muindasitiri yekugadzira bhodhi redunhu, Capel inounza 15 makore ehunyanzvi uye timu yakazvitsaurira yehunyanzvi hwehunyanzvi kuti ikubatsire panguva yese yekusarudza.

I. Kunzwisisa Rigid PCBs

Nekuda kwehunhu hwawo hwakasimba uye husingachinji, maPCB akaomarara anga ari sarudzo yechinyakare kune akawanda emagetsi maapplication.Iyo inogadzirwa uchishandisa yakasimba, yakasimba substrate, kazhinji inoumbwa nefiberglass kana composite epoxy resin.Heano mamwe emhando huru uye mabhenefiti eakaomarara PCBs:

1. Mechanical Strength: Rigid PCBs dzine simba rakanakisa remagetsi uye rakanakira zvikumbiro zvinoda kugadzikana uye kutsigirwa.Kuvakwa kwadzo kwakasimba kunoita kuti isanyanya kukanganiswa nemasimba ekunze.

2. High component density: Rigid PCB inogonesa high component density, iyo inobatsira pakugadzirisa kwakaoma.Iyi ficha inonyanya kubatsira kune zvishandiso zvinoda nhamba yakakura yezvikamu kuti zvirongedzwe munzvimbo diki.

3. Kupisa kupisa: Nekuda kwechimiro chayo chakasimba, PCB yakasimba inokwanisa kudzima kupisa zvakanaka, kuve nechokwadi chekushanda kwakanaka uye kuvimbika kunyange pasi pemitoro yakanyanya kupisa.

4. Mutengo-Kushanda: Kugadzirwa kweMisa kwemaPCB akaomarara kazhinji kunoderedza mutengo weyuniti, zvichiita kuti ive sarudzo ine mari yemapurojekiti makuru emagetsi.

2. Ongorora inochinjika PCB

Flexible PCBs, sekureva kunoita zita, akagadzirwa kuti akwanise kuchinjika uye anogona kukotama kana kumonyaniswa kuti aenderane neakasiyana maapplication.Iwo anogadzirwa kubva kuchinjika polymer substrates senge polyimide kana PEEK (polyetheretherketone).Ngatitarisei zvakadzama mabhenefiti uye matanho ekuzvidzivirira kwePCB inoshanduka:

1. Space constraints: Flexible PCBs inopa isingaenzaniswi yekumisikidza kuchinjika, ichivaita sarudzo yakanaka kune compact zvishandiso uko tsika dzakaomarara PCB dzinogona kusakwana.Kugona kwavo kupeta kunonatsiridza kushandiswa kwenzvimbo uye kunowedzera dhizaini mikana.

2. Kuderedza uremu: Kuenzaniswa nePCB yakaoma, inoshanduka PCB yakareruka, iyo inobatsira zvikuru kune zvigadzirwa zvinotakurika zvinoda kuderedza uremu.

3. Durability: Flexible PCB ine yakakwirira kuramba kuzunguzika, kukanganisa uye kukanganisa, uye inokodzera zvikumbiro munzvimbo dzakaoma kana nzvimbo dzinogara dzichifamba.

4. Complex circuits: Aya maPCB anokwanisa kushandisa masekete akaoma uye wiring maitiro nekuda kwekushanduka kwavo, zvichiita kuti vave sarudzo yekutanga yezvigadzirwa zvemagetsi zvepamusoro zvinoda maitiro akaoma.

3.Factors kufunga pakusarudza PCB mhando

Zvino zvataongorora mabhenefiti emaPCB akaomarara uye anochinjika, ngatikurukurei zvimwe zvezvinhu zvakakosha zvekufunga nezvazvo pakusarudza mhando yePCB chaiyo:

1. Zvido zvekushandisa: Nzwisisa zvinodiwa chaizvo zvepurojekiti yako.Kana iyo compact dhizaini, ine simba kufamba kana kureruka kuvaka kuchidikanwa, inoshanduka PCB inogona kunge iri sarudzo yakanyanya kunaka.Rigid PCBs, kune rumwe rutivi, inokunda mumashandisirwo anoda yakakwirira chikamu density, kugadzikana, uye simba remuchina.

2. Mamiriro ezvakatipoteredza uye ekushanda: Ongorora mamiriro ezvakatipoteredza umo midziyo yako yemagetsi inoshanda.Flexible PCBs inogona kupa kusimba uye hupenyu hurefu kana yakafumurwa kune yakanyanya tembiricha, kuzunguza kwakanyanya, kana mamwe mamiriro akaomarara.

3. Mutengo uye kufunga kwekugadzira: Ongorora mutengo wekugadzira uye kugona kweimwe neimwe PCB mhando.Rigid PCBs dzinowanzoita-inodhura-inoshanda pakugadzirwa kwakawanda, nepo maPCB anochinjika angasanganisira mamwe matanho ekugadzira nemidziyo yakasarudzika, zvichikonzera mutengo wakakwira.

4. Dhizaini yakaoma: Funga nezvekuoma kwekugadzira dunhu.Kana akawanda akaturikidzana achibatanidzwa, yakaoma wiring inodiwa, kana 3D nzvimbo inoda kushandiswa, inochinjika maPCB anogona kupa zvirinani dhizaini inoshanduka.

Mukupedzisa:

Kusarudza mhando yePCB chaiyo kwakakosha pakubudirira kweprojekiti yako yemagetsi.Akaomarara uye anochinjika maPCB ega ega ane zvawo zvakanakira uye kufunga.Nekunzwisisa izvo zvakasarudzika zvemhando yega yega uye nekufunga zvinhu zvakaita sezvinodiwa zvekushandisa, mamiriro ezvakatipoteredza, mutengo uye dhizaini yakaoma, iwe unozogona kuita sarudzo ine ruzivo.Nemakore gumi nemashanu eCapel eruzivo rwekugadzira bhodhi redunhu uye timu yakazvipira yenyanzvi dzehunyanzvi padivi pako, unogona kuvimba nesu kuti tinokupa nhungamiro nerutsigiro rwaunoda mukati mekuita sarudzo.Ramba uchifunga kuti sarudzo pakati pePCB dzakaomarara uye dzinochinjika pakupedzisira zvinoenderana nezvinodiwa uye zvinangwa zvepurojekiti.
