Ukuhlanganisa okushisayo nokushisa kokushisa | I-Rigid Flex Rigid Pcb | amandla aphezulu | izinga lokushisa eliphezulu

Ezweni lanamuhla lobuchwepheshe elisheshayo, isidingo semishini kagesi siyaqhubeka sikhula ngesivinini esimangalisayo. Kusukela kuma-smartphones kuya kumishini yezokwelapha, isidingo samabhodi esekethe asebenza kahle nathembekile sibalulekile.Olunye uhlobo oluthile lwebhodi lesifunda oluya luduma kakhulu i-PCB eqinile-flex-rigid.

I-Rigid-flex rigid PCBs inikeza inhlanganisela eyingqayizivele yokuguquguquka nokuhlala isikhathi eside, okuwenza alungele izinhlelo zokusebenza lapho isikhala silinganiselwe noma ibhodi lidinga ukukwazi ukumelana nezindawo ezinokhahlo. Kodwa-ke, njenganoma yiliphi elinye ibhodi lesifunda, ama-PCB aqinile aqinile awavikelekile ezinseleleni ezithile, njengokuhlanganisa okushisayo nezinkinga zokuqhuba ukushisa.

Ukuhlanganisa okushisayo kwenzeka lapho ukushisa okukhiqizwa ingxenye eyodwa ebhodini kudluliselwa engxenyeni eseduze, okubangela amazinga okushisa akhuphukile kanye nezinkinga zokusebenza ezingaba khona. Le nkinga iba nkulu kakhulu ezindaweni ezinamandla amakhulu nezinezinga lokushisa eliphezulu.

Ngakho-ke, ukuxazulula kanjani ukuhlangana okushisayo kanye nezinkinga zokuqhuba okushisayo kwe-rigid flex rigid pcb, ikakhulukazi emandleni aphezulu nasezindaweni zokushisa okuphezulu? Ngokujabulisayo, kunamasu amaningana asebenzayo ongawasebenzisa.

1. Ukucatshangelwa kwedizayini eshisayo:

Esinye sezihluthulelo zokunciphisa ukuhlanganisa okushisayo nezindaba zokuqhuba ukushisa ukucabangela ukuphathwa kokushisa lapho uklama isakhiwo se-PCB. Lokhu kuhlanganisa ngokuhlelekile ukubeka izingxenye eziphehla ukushisa ebhodini, ukuqinisekisa ukuthi kunezikhala ezifanele phakathi kwezingxenye, futhi kucatshangelwa ukusetshenziswa kwe-thermal vias nama-thermal pads ukuze kube lula ukuqeda ukushisa.

2. Ukubekwa kwengxenye efanele:

Ukubekwa kwezingxenye zokushisisa kuma-PCB aqinile aguquguqukayo kufanele kucatshangelwe ngokucophelela. Ngokubeka lezi zingxenye endaweni enomoya owanele noma usinki wokushisa, ithuba lokuhlangana okushisayo lingancishiswa kakhulu. Ukwengeza, ukuqoqa izingxenye ezinamaleveli okusebenzisa amandla afanayo kungasiza ukusabalalisa ukushisa ngokulinganayo kuyo yonke ibhodi.

3. Ubuchwepheshe obusebenzayo bokulahla ukushisa:

Ezindaweni ezinamandla amakhulu nezishisa kakhulu, izindlela zokupholisa ezisebenzayo zibalulekile. Ukukhetha ngokucophelela osinki bokushisa, amafeni, nezinye izindlela zokupholisa kungasiza ekukhipheni ukushisa kahle futhi kuvimbele ukuhlangana kokushisa. Ukwengeza, ukusetshenziswa kwezinto ezishintshayo ezishisayo, njengamaphedi esibonakalayo esishisayo noma amafilimu, kungathuthukisa ukudluliswa kokushisa phakathi kwezingxenye namasinki okushisa.

4. Ukuhlaziya okushisayo kanye nokulingisa:

Ukuhlaziya okushisayo nokulingisa okwenziwa kusetshenziswa isofthiwe ekhethekile kunganikeza imininingwane ebalulekile ekuziphatheni okushisayo kwama-PCB aqinile-flex-rigid. Lokhu kwenza onjiniyela bakwazi ukuhlonza izindawo ezishisayo ezingaba khona, bathuthukise isakhiwo sengxenye, futhi benze izinqumo ezinolwazi mayelana nobuchwepheshe obushisayo. Ngokubikezela ukusebenza okushisayo kwamabhodi esekethe ngaphambi kokukhiqiza, ukuhlanganisa okushisayo nezinkinga zokuqhuba ukushisa kungaxazululwa ngokuqhubekayo.

5. Ukukhetha impahla:

Ukukhetha izinto ezifanele zama-PCB aqinile aguquguqukayo kubalulekile ekulawuleni ukuhlangana okushisayo nokuqhutshwa kokushisa. Ukukhetha izinto ezine-conductivity ephezulu ye-thermal kanye nokumelana nokushisa okuphansi kungathuthukisa amandla okukhipha ukushisa. Ukwengeza, ukukhetha izinto ezinezici ezinhle zomshini kuqinisekisa ukuguquguquka kwebhodi nokuqina, ngisho nasezindaweni ezinezinga lokushisa eliphezulu.

Ngokufigqiwe

Ukuxazulula izinkinga ze-thermal coupling kanye ne-thermal conduction yamabhodi aqinile-flex ezindaweni ezinamandla amakhulu kanye nezinga lokushisa eliphezulu kudinga inhlanganisela yomklamo ohlakaniphile, ubuchwepheshe obusebenzayo bokulahla ukushisa, nokukhethwa kwezinto ezifanele.Ngokucubungula kahle ukuphathwa okushisayo ngesikhathi sokuhlelwa kwe-PCB, ukwenza ngcono ukubekwa kwengxenye, ukusebenzisa amasu afanele okukhipha ukushisa, ukwenza ukuhlaziya okushisayo, nokukhetha izinto ezifanele, onjiniyela bangaqinisekisa ukuthi ama-PCB aqinile asebenza ngokuthembekile ngaphansi kwezimo eziyinselele. Njengoba isidingo semishini ye-elekthronikhi siqhubeka sikhula, ukubhekana nalezi zinselele ezishisayo kuba kubaluleke kakhulu ekusetshenzisweni ngempumelelo kwama-PCB aqinile aguquguqukayo ezinhlobonhlobo zezinhlelo zokusebenza.
