Bala ukusebenza okushisayo kwedizayini ye-PCB eguquguqukayo

Kule bhulogi, sizohlola izindlela nezibalo ezidingekayo ukuze sinqume ukusebenza okushisayo kwemiklamo ye-PCB eguquguqukayo.

Lapho uklama ibhodi lesifunda eliphrintiwe (PCB), enye yezinto ezibalulekile onjiniyela okudingeka bazicabangele ukusebenza kwalo okushisayo.Ngokuthuthuka okusheshayo kobuchwepheshe kanye nesidingo esiqhubekayo samadivayisi kagesi ahlangene futhi anamandla, ukuchithwa kokushisa okuvela kuma-PCB sekube inselele enkulu.Lokhu kuyiqiniso ikakhulukazi kumadizayini we-PCB aguquguqukayo ahlanganisa izinzuzo zamabhodi esekethe aqinile navumelana nezimo.

Ukusebenza okushisayo kudlala indima ebalulekile ekuqinisekiseni ukwethembeka nokuphila isikhathi eside kwamadivayisi kagesi.Ukwanda kokushisa okwedlulele kungaholela ezinkingeni ezihlukahlukene, njengokuhluleka kwengxenye, ukonakala kokusebenza, ngisho nezingozi zokuphepha.Ngakho-ke, kubalulekile ukuhlola nokwandisa ukusebenza okushisayo kwama-PCB phakathi nesigaba sokuklama.

Nazi ezinye izinyathelo ezibalulekile zokubala ukusebenza okushisayo kwemiklamo ye-PCB eguquguqukayo:

1. Thola izici ezishisayo: Okokuqala, kubalulekile ukuqoqa ulwazi oludingekayo mayelana nokuhamba kwe-thermal kanye nomthamo wokushisa othize wezinto ezisetshenziswa kumiklamo ye-PCB eguquguqukayo.Lokhu kuhlanganisa izendlalelo ze-conductive, izendlalelo ezivikelayo, nanoma imaphi amasinki okushisa engeziwe noma ama-vias.Lezi zici zinquma amandla e-PCB okukhipha ukushisa.

2. Ukubalwa Kokumelana Nokushisa: Isinyathelo esilandelayo sihlanganisa ukubala ukumelana nokushisa kwezendlalelo ezahlukene kanye nezindawo zokusebenzelana kumklamo we-PCB oguquguqukayo.Ukumelana nokushisa kuyisilinganiso sokuthi into noma isixhumi esibonakalayo kuqhuba kahle kangakanani ukushisa.Ivezwa ngamayunithi ka-ºC/W (Celsius per Watt).Ukunciphisa ukumelana nokushisa, kungcono ukudluliswa kokushisa.

3. Thola izindlela ezishisayo: Thola izindlela ezishisayo ezishisayo kumiklamo ye-PCB eguquguqukayo eqinile.Lezi izindlela ezihamba ngazo ukushisa okukhiqizwayo.Kubalulekile ukucabangela zonke izingxenye eziphehla ukushisa njengama-IC, amadivaysi kagesi, nanoma yiziphi ezinye izingxenye ezikhiqiza ukushisa.Hlaziya indlela yokugeleza kokushisa ukusuka emthonjeni wokushisa kuya endaweni ezungezile futhi uhlole umthelela wezinto ezihlukene nezendlalelo kule ndlela.

4. Ukulingisa nokuhlaziya okushisayo: Sebenzisa isofthiwe yokuhlaziya ukushisa ukuze ulingise ukuchithwa kokushisa kumklamo webhodi eliguquguqukayo.Amathuluzi amaningana esofthiwe, afana ne-ANSYS Icepak, i-SOLIDWORKS Flow Simulation noma i-Mentor Graphics FloTHERM, ahlinzeka ngamakhono athuthukile wokumodela ngokunembile nokubikezela ukuziphatha okushisayo.Lezi zifaniso zingasiza ekuhlonzeni izindawo ezishisayo ezingaba khona, zihlole izinketho zokuklama ezihlukahlukene futhi zithuthukise ukusebenza okushisayo.

5. Ukuthuthukisa usinki wokushisa: Uma kudingeka, isinki sokushisa singafakwa ukuze kuthuthukiswe ukusebenza okushisayo kwedizayini ye-PCB eguquguqukayo eguquguqukayo.Osinki bokushisa bandisa indawo engaphezulu etholakalayo yokukhipha ukushisa futhi bathuthukise ukudluliswa kokushisa kukonke.Ngokusekelwe emiphumeleni yokulingisa, khetha idizayini yesikhombi sokushisa esifanelekile, ucabangela izici ezifana nosayizi, okubalulekile, nesakhiwo.

6. Hlola ezinye izinto zokwakha: Hlola umthelela wezinketho zezinto ezibonakalayo ekusebenzeni okushisayo kwemiklamo ye-PCB eguquguqukayo.Ezinye izinto zenza ukushisa kangcono kunezinye futhi zingathuthukisa kakhulu amandla okukhipha ukushisa.Cabangela izinketho ezifana nama-substrates e-ceramic noma izinto ze-PCB ze-thermal conductive, ezinganikeza ukusebenza okungcono okushisayo.

7. Ukuhlola nokuqinisekisa okushisayo: Ngemva kokuqedwa komklamo nokulingisa, kubalulekile ukuhlola nokuqinisekisa ukusebenza okushisayo koqobo lwangempela.i-rigid-flex PCB prototype.Sebenzisa ikhamera eshisayo noma ama-thermocouples ukuthatha izilinganiso zezinga lokushisa ezindaweni ezibalulekile.Qhathanisa izilinganiso nezibikezelo zokulingisa bese uphinda umklamo uma kudingeka.

Kafushane, ukubala ukusebenza okushisayo kwemiklamo ye-PCB eguquguqukayo kuwumsebenzi oyinkimbinkimbi odinga ukucatshangelwa ngokucophelela kwezakhiwo zezinto ezibonakalayo, ukumelana nokushisa, nezindlela ezishisayo.Ngokulandela izinyathelo ezingenhla nokusebenzisa isofthiwe yokulingisa ethuthukisiwe, onjiniyela bangathuthukisa amadizayini ukuze bathole ukunqanyulwa kokushisa okusebenzayo futhi bathuthukise ukuthembeka kukonke kanye nokusebenza kwamadivayisi kagesi.

Khumbula, ukuphatha okushisayo kuyisici esibalulekile sokwakheka kwe-PCB, futhi ukuyishaya indiva kungaba nemiphumela emibi.Ngokubeka phambili izibalo zokusebenza okushisayo nokusebenzisa amasu afanele, onjiniyela bangaqinisekisa impilo ende nokusebenza kwemishini kagesi, ngisho nasezinhlelweni ezifunwa kakhulu.
