Bala ukusebenza thermal yoyilo PCB engqongqo-flex

Kule bhlog, siza kuphonononga iindlela kunye nezibalo ezifunekayo ukufumanisa ukusebenza kwe-thermal yoyilo lwe-PCB eguquguqukayo.

Xa kuyilwa ibhodi yesekethe eprintiweyo (PCB), enye yezinto eziphambili iinjineli kufuneka ziqwalaselwe kukusebenza kwayo kwe-thermal.Ngokuhambela phambili ngokukhawuleza kwetekhnoloji kunye nemfuno eqhubekayo yezixhobo zombane ezixineneyo nezinamandla, ukukhutshwa kobushushu kwiiPCB kube ngumngeni omkhulu. Oku kuyinyani ngokukodwa kuyilo lwe-PCB elukhuni edibanisa iibhodi zesekethe eziqinileyo neziguquguqukayo.

Ukusebenza kwe-Thermal kudlala indima ebalulekileyo ekuqinisekiseni ukuthembeka kunye nokuphila ixesha elide kwezixhobo zombane.Ukwanda kobushushu obugqithisileyo kunokukhokelela kwimiba eyahlukeneyo, njengokungaphumeleli kwecandelo, ukuthotywa komgangatho wokusebenza, kunye neengozi zokhuseleko. Ngoko ke, kubalulekile ukuvavanya kunye nokwandisa ukusebenza kwe-thermal ye-PCB ngexesha lesigaba soyilo.

Nanga amanye amanyathelo angundoqo okubala ukusebenza kwe-thermal yoyilo lwe-PCB eguquguqukayo:

1. Ukumisela iimpawu ze-thermal: Okokuqala, kubalulekile ukuqokelela ulwazi oluyimfuneko malunga ne-thermal conductivity kunye nomthamo obushushu obuthile bezinto ezisetyenziselwa ukuyila kwe-PCB eguquguqukayo.Oku kuquka iileya conductive, umaleko insulating, kunye nazo naziphi na iisinki ubushushu ezongezelelweyo okanye vias. Ezi mpawu zimisela amandla okuphelisa ubushushu bePCB.

2. Ukubalwa kwe-Thermal Resistance: Inyathelo elilandelayo libandakanya ukubala ukuxhathisa kwe-thermal yemigangatho eyahlukeneyo kunye nojongano kwi-design ye-PCB eguquguqukayo.Ukumelana ne-thermal ngumlinganiselo wendlela ngokufanelekileyo into okanye i-interface eqhuba ngayo ukushisa. Ibonakaliswa ngeeyunithi ze-ºC/W (Celsius ngeWatt nganye). Ukunciphisa ukunyanzeliswa kwe-thermal, ngcono ukuhanjiswa kobushushu.

3. Misela iindlela ezishushu: Misela iindlela ezibalulekileyo ze-thermal kuyilo lwe-PCB eguquguqukayo.Ezi ziindlela ezihamba ngazo ubushushu obuveliswayo. Kubalulekile ukuqwalasela onke amacandelo avelisa ubushushu afana nee-IC, izixhobo zamandla, kunye nawo nawaphi na amanye amacandelo avelisa ubushushu. Hlalutya indlela yokuhamba kobushushu ukusuka kumthombo wobushushu ukuya kwindawo engqongileyo kwaye uvavanye impembelelo yezinto ezahlukeneyo kunye neengqimba kule ndlela.

4. Ukulinganisa kunye nohlalutyo lwe-thermal: Sebenzisa isofthiwe yokuhlalutya i-thermal ukulinganisa ukutshatyalaliswa kobushushu kwi-rigid-flex board design.Izixhobo ezininzi zesoftware, ezifana ne-ANSYS Icepak, i-SOLIDWORKS Flow Simulation okanye i-Mentor Graphics FloTHERM, ibonelela ngezakhono eziphambili zokubonisa ngokuchanekileyo kunye nokuqikelela ukuziphatha kwe-thermal. Ezi zifaniso zinokunceda ekuchongeni iindawo ezinokuthi zishushu, zivavanye iindlela ezahlukeneyo zoyilo kunye nokwandisa ukusebenza kwe-thermal.

5. Ukulungiswa kwe-Heat sink optimization: Ukuba kuyimfuneko, i-heat sink inokubandakanywa ukuphucula ukusebenza kwe-thermal yoyilo lwe-PCB eguquguqukayo.Iisinki zokushisa zandisa indawo ekhoyo yokutshatyalaliswa kobushushu kunye nokuphucula ukuhanjiswa kobushushu ngokubanzi. Ngokusekwe kwiziphumo zokulinganisa, khetha uyilo olufanelekileyo lwesitya sokutshisa ubushushu, uthathela ingqalelo izinto ezinje ngobungakanani, imathiriyeli, kunye noyilo.

6. Vavanya ezinye izinto: Vavanya ifuthe lezinto ezikhethiweyo ezahlukeneyo ekusebenzeni kwe-thermal ye-rigid-flex PCB designs.Ezinye izixhobo ziqhuba ngcono ubushushu kunezinye kwaye zinokwandisa kakhulu amandla okuphelisa ubushushu. Cinga iinketho ezifana ne-ceramic substrates okanye izixhobo ze-PCB eziqhuba i-thermal, ezinokubonelela ngokusebenza okungcono kwe-thermal.

7. Uvavanyo lwe-thermal kunye nokuqinisekiswa: Emva kokuba uyilo kunye nokulinganisa kugqityiwe, kubalulekile ukuvavanya kunye nokuqinisekisa ukusebenza kwe-thermal yeyona nto.eqinile-flex iprototype PCB.Sebenzisa ikhamera ye-thermal okanye i-thermocouples ukuthatha imilinganiselo yobushushu kwiindawo eziphambili. Thelekisa imilinganiselo kuqikelelo lokulinganisa kwaye uphinde uyilo ukuba kuyimfuneko.

Isishwankathelo, ukubala ukusebenza kwe-thermal yoyilo lwe-PCB elukhuni-flex ngumsebenzi onzima ofuna ukuqwalaselwa ngokucophelela kweempawu eziphathekayo, ukuxhathisa ukushisa, kunye neendlela zokushisa.Ngokulandela la manyathelo angasentla kunye nokuxhasa isoftware yokulinganisa ephucukileyo, iinjineli zinokuluphucula uyilo ukufezekisa ukutshabalalisa ubushushu kunye nokuphucula ukuthembeka kunye nokusebenza kwezixhobo zombane.

Khumbula, ulawulo lwe-thermal yinkalo ebalulekileyo yoyilo lwePCB, kwaye ukungayihoyi kunokuba nemiphumo emibi.Ngokubeka phambili izibalo zokusebenza kwe-thermal kunye nokusebenzisa ubuchule obufanelekileyo, iinjineli zinokuqinisekisa ixesha elide kunye nokusebenza kwezixhobo zombane, nakwizicelo ezifunayo.
