Ndi zipangizo ziti zomwe zimagwiritsidwa ntchito pa PCB board prototypes?

Zikafika pa PCB board prototyping, kusankha zinthu zoyenera ndikofunikira. Zida zomwe zimagwiritsidwa ntchito muzojambula za PCB zitha kukhudza kwambiri magwiridwe antchito, kudalirika, komanso kulimba kwa chinthu chomaliza.Mu positi iyi yabulogu, tiwona zina mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi PCB board ndikukambirana zabwino ndi zovuta zawo.

1.FR4:

FR4 ndiye chinthu chomwe chimagwiritsidwa ntchito kwambiri pa PCB board prototyping. Ndi galasi-reinforced epoxy laminate yomwe imadziwika kuti ndi yabwino kwambiri yotchinjiriza magetsi. FR4 ilinso ndi kukana kutentha kwambiri, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafunikira kutentha kwambiri.

Chimodzi mwazabwino zazikulu za FR4 ndikuchita bwino kwake. Ndiotsika mtengo poyerekeza ndi zipangizo zina pamsika. Kuphatikiza apo, FR4 imakhala yokhazikika pamakina ndipo imatha kupirira kupsinjika kwakukulu popanda kupunduka kapena kusweka.

Komabe, FR4 ili ndi zoletsa zina. Sikoyenera kugwiritsa ntchito zomwe zimafuna kuti zizichitika pafupipafupi chifukwa chokhala ndi ma dielectric pafupipafupi. Kuphatikiza apo, FR4 siyoyenera kugwiritsa ntchito zomwe zimafuna kutayika pang'ono kapena kuwongolera kolimba.

2. Rogers:

Rogers Corporation ndi chisankho china chodziwika cha PCB board prototyping. Zida za Rogers zimadziwika chifukwa chogwira ntchito kwambiri, zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito zinthu zosiyanasiyana, kuphatikiza malo opangira ndege, matelefoni ndi mafakitale amagalimoto.

Zida za Rogers zili ndi magetsi abwino kwambiri, kuphatikiza kuchepa kwa dielectric, kupotoza kwa ma siginecha otsika komanso kutsika kwamafuta ambiri. Amakhalanso okhazikika bwino ndipo amatha kupirira zovuta zachilengedwe.

Komabe, choyipa chachikulu cha zida za Rogers ndi mtengo wawo wokwera. Zida za Rogers ndizokwera mtengo kwambiri kuposa FR4, zomwe zitha kukhala zolepheretsa ntchito zina.

3. Chitsulo chachitsulo:

Metal Core PCB (MCPCB) ndi mtundu wapadera wa PCB board prototype yomwe imagwiritsa ntchito chitsulo pakati m'malo mwa epoxy kapena FR4 monga gawo lapansi. Chitsulo chachitsulo chimapereka kutentha kwabwino kwambiri, kupangitsa MCPCB kukhala yoyenera ntchito zomwe zimafuna ma LED amphamvu kwambiri kapena zida zamagetsi zamagetsi.

MCPCB imagwiritsidwa ntchito kwambiri pamakampani opanga zowunikira, magalimoto oyendetsa magalimoto komanso zamagetsi zamagetsi. Iwo amapereka kasamalidwe bwino matenthedwe poyerekeza PCBs chikhalidwe, potero kuwonjezera kudalirika wonse ndi moyo wautali wa mankhwala.

Komabe, MCPCB ili ndi zovuta zina. Iwo ndi okwera mtengo kuposa PCBs chikhalidwe, ndipo pachimake zitsulo n'zovuta kwambiri makina pakupanga ndondomeko. Kuphatikiza apo, MCPCB ili ndi kusinthasintha kochepa ndipo siyoyenera kugwiritsa ntchito zomwe zimafuna kupindika kapena kupindika.

Kuphatikiza pa zinthu zomwe zatchulidwa pamwambapa, palinso zida zina zapadera zomwe zimagwiritsidwa ntchito mwapadera. Mwachitsanzo, PCB yosinthika imagwiritsa ntchito filimu ya polyimide kapena poliyesitala ngati maziko, omwe amalola PCB kupinda kapena kusinthasintha. Ceramic PCB imagwiritsa ntchito zida za ceramic ngati gawo lapansi, lomwe lili ndi matenthedwe abwino kwambiri komanso magwiridwe antchito apamwamba kwambiri.

Powombetsa mkota, kusankha zinthu zoyenera kwa PCB board prototype yanu ndikofunikira kuti mukwaniritse magwiridwe antchito, kudalirika, komanso kulimba. FR4, Rogers, ndi zida zachitsulo ndi zina mwazosankha zodziwika bwino, chilichonse chili ndi zabwino zake komanso zovuta zake. Ganizirani zofunikira za polojekiti yanu ndikukambirana ndi katswiri wopanga PCB kuti mudziwe zida zabwino kwambiri za PCB yanu.
