Kulumikizana kwamafuta ndi kuwongolera kutentha | Rigid Flex Rigid Pcb | apamwamba | malo otentha kwambiri

M’dziko lamakono lamakono lazamisiri, kufunikira kwa zipangizo zamagetsi kukukulirakulirabe modabwitsa. Kuchokera ku mafoni a m'manja kupita ku zipangizo zachipatala, kufunikira kwa matabwa oyendetsa bwino komanso odalirika ndikofunikira.Mtundu umodzi wa bolodi wozungulira womwe ukuchulukirachulukira kwambiri ndi PCB yolimba-flex-rigid.

Ma PCB olimba-flex okhwima amapereka kuphatikiza kwapadera kwa kusinthasintha ndi kulimba, kuwapangitsa kukhala abwino kwa mapulogalamu omwe malo ali ochepa kapena bolodi imayenera kupirira malo ovuta. Komabe, monga gulu lina lililonse loyang'anira dera, ma PCB olimba okhazikika sakhala ndi zovuta zina, monga kuphatikizika kwamafuta ndi nkhani zowongolera kutentha.

Kulumikizana kwamafuta kumachitika pamene kutentha kopangidwa ndi gawo limodzi pa bolodi kumasamutsidwa ku gawo loyandikana nalo, zomwe zimapangitsa kutentha kwambiri komanso zovuta zomwe zingachitike. Vutoli limakhala lofunika kwambiri m'malo okhala ndi mphamvu komanso kutentha kwambiri.

Ndiye, momwe mungathetsere matenthedwe ophatikizana ndi matenthedwe amtundu wa regid flex rigid pcb, makamaka mumphamvu kwambiri komanso malo otentha kwambiri? Mwamwayi, pali njira zingapo zothandiza zomwe mungagwiritse ntchito.

1. Malingaliro opangira kutentha:

Chimodzi mwamakiyi ochepetsera kuphatikizika kwamafuta ndikuwongolera kutentha ndikuganizira kasamalidwe kamafuta popanga masanjidwe a PCB. Izi zikuphatikizapo mwanzeru kuyika zigawo zopangira kutentha pa bolodi, kuonetsetsa kuti pali kusiyana koyenera pakati pa zigawozo, ndikuganizira kugwiritsa ntchito njira zotentha ndi matenthedwe kuti zithetse kutentha.

2. Kuyika kwachigawo moyenera:

Kuyika kwa zida zotenthetsera pa PCB zolimba zolimba kuyenera kuganiziridwa bwino. Poyika zigawozi m'dera lokhala ndi mpweya wokwanira kapena kutentha kwa kutentha, mwayi wogwirizanitsa kutentha ukhoza kuchepetsedwa kwambiri. Kuonjezera apo, kupanga magulu omwe ali ndi mphamvu zofanana zogwiritsira ntchito mphamvu kungathandize kugawa kutentha mofanana pagulu lonse.

3. Ukadaulo wothandiza wochotsa kutentha:

M'malo okhala ndi mphamvu zambiri komanso kutentha kwambiri, njira zoziziritsa bwino ndizofunikira. Kusankha mosamala zoyikira kutentha, mafani, ndi njira zina zoziziritsira kungathandize kutulutsa kutentha bwino ndikuletsa kulumikizana kwamafuta. Kuonjezera apo, kugwiritsa ntchito zipangizo zopangira thermally, monga mapepala opangira matenthedwe kapena mafilimu, zimatha kupititsa patsogolo kutentha pakati pa zigawo ndi zozama za kutentha.

4. Kusanthula kwa kutentha ndi kuyerekezera:

Kusanthula kwamafuta ndi kuyerekezera kochitidwa pogwiritsa ntchito mapulogalamu apadera kungapereke chidziwitso chofunikira pamayendedwe amatenthedwe a PCBs okhwima-flex-rigid. Izi zimathandiza mainjiniya kuzindikira malo omwe atha kukhala otentha, kukhathamiritsa makonzedwe azinthu, ndikupanga zisankho zodziwika bwino zaukadaulo wamatenthedwe. Polosera momwe matenthedwe amayendera ma board board asanapangidwe, kulumikizana kwamafuta ndi nkhani zowongolera kutentha zitha kuthetsedwa mwachangu.

5. Kusankha zinthu:

Kusankha zida zoyenera za ma PCB okhazikika okhazikika ndikofunikira pakuwongolera kulumikizana kwamafuta ndi kuwongolera kutentha. Kusankha zida zokhala ndi matenthedwe apamwamba kwambiri komanso kukana kwamafuta ochepa kumatha kukulitsa luso la kutaya kutentha. Kuphatikiza apo, kusankha zinthu zokhala ndi makina abwino kumatsimikizira kusinthasintha kwa bolodi komanso kulimba, ngakhale m'malo otentha kwambiri.

Powombetsa mkota

Kuthetsa kuphatikizika kwamafuta ndi zovuta zoyendetsera matenthedwe a matabwa olimba-osinthasintha m'malo okhala ndi mphamvu zambiri komanso kutentha kwambiri kumafuna kuphatikiza kwanzeru, ukadaulo wogwira ntchito wochotsa kutentha, komanso kusankha zinthu zoyenera.Poganizira mosamalitsa kasamalidwe ka matenthedwe pa PCB masanjidwe, kukhathamiritsa kuyika kwa chigawo, kugwiritsa ntchito njira zoyenera zoyatsira matenthedwe, kusanthula kutentha, ndikusankha zida zoyenera, akatswiri amatha kuwonetsetsa kuti ma PCB okhazikika okhazikika amagwira ntchito modalirika pamavuto. Pomwe kufunikira kwa zida zamagetsi kukukulirakulira, kuthana ndi zovuta zamatenthedwezi kumakhala kofunika kwambiri kuti pakhale kukhazikitsidwa bwino kwa ma PCB okhwima okhwima munjira zosiyanasiyana.
