I-Potting Material Ye-Electronics Nendlela Yokukhetha Okungcono Kakhulu

Ukubumba kungachazwa njengenqubo yokugcwalisa umhlangano we-elekthronikhi ngokuqinile ukuze kuthuthukiswe amazinga ayo okumelana. Kubuye kwaziwe njengokushumeka futhi kwenza izingxenye namaassembles amelane nokudlidliza, ukushaqeka, izinto ezilimazayo, amakhemikhali, amanzi, ngisho nomswakama nokushisa. Ibhokisi lokubhaka, ngokuvamile isikhwama sepulasitiki esincane, sisetshenziselwa ukubeka izinto, njenge-PCB, futhi inhlaka esesimweni esiwuketshezi iyagcwaliswa bese ivunyelwa ukuba yelaphe. Ibhokisi lingaba futhi imbobo endaweni ebiyelwe enkulu ukuze kuvikelwe okukhethekile ezindaweni ezithile zomhlangano noma zebhodi lesifunda.

I-potting electronics njengamabhodi esekethe aphrintiwe kwenyusa ukuvikeleka ekuvuzeni kwamandla kagesi, umswakama, nezinye izingozi ezingase ziwalimaze. Ukusebenza okuthuthukisiwe kwe-elekthronikhi kanye nesekethe enokwethenjelwa ezinye zezinzuzo ozozithola lapho wenza ibhodwe.

Inqubo iphinde isize ekugcineni ukudlidliza kanye nemithelela yokushaqeka imincane. Umthelela onjalo ungashiya izinto zikagesi zingasebenzi njengoba ziphazamisa izintambo nokuxhuma. Amagagasi okudlidliza kumabhodi esekethe namakesi awo nawo akhulisa ingcindezi okuholela ekuhlulekeni kwangaphambi kwesikhathi kwezinto zikagesi. Ngakho-ke, lapho ufaka imbiza, ukhulisa ubude bempilo yedivayisi njengoba izomelana nokudlidliza kanye nemiphumela yokushaqeka.

Ama-electronics asezimbiza nawo avikelekile ekungcoleni nasothulini, okungaholela ekushiseni ngokweqile, ngaleyo ndlela kuthinte isivinini, ukusebenza, nesignali yedivayisi kagesi. I-epoxy, i-urethane, ne-silicone yizinto ezinkulu ezisetshenziswa ekubumbeni. Ngokubheka izici nezakhiwo zayo ngayinye, kufanele ukwazi ukunquma ukuthi iyiphi izinto zokwakha ze-elekthronikhi kungcono kakhulu. Izindaba ezinhle ukuthi uzohlala uthola into evumelana kangcono nezidingo zakho zesicelo.

Ama-epoxy potting compounds

Njenge-potting compound, i-epoxy inikeza ukunamathela okuhle ngakho-ke ivikela izingxenye zikagesi isikhathi eside. Lena impahla esebenza yodwa ngaphandle kwesidingo sokwengeza ama-primers lapho kugaywa izinto zikagesi. Amandla aphezulu aqinile, imodulus, nokuqina kukwenza kube ukukhetha okuhle kakhulu kuma-elekthronikhi amaningi, ikakhulukazi lawo okusetshenziswa ngaphandle njengamadivayisi ezolimo, ama-transformer, namaswishi.

Izithako ze-Urethane potting 

Njenge i-potting compound, ubude, ukuguquguquka, nokumelana nokuhuzuka kukwenza ukukhetha okuhle, ikakhulukazi ezicini ezibucayi ezidinga ukuphathwa okuthambile. Amadivayisi aqukethe ama-substrates afana nengilazi, amapulasitiki, izitsha zobumba, nama-alloys ensimbi azothanda i-urethane njengento yokubumba.

I-silicone potting compounds

Njengenhlanganisela yokupheka, ukuguquguquka kwe-silicone kuyenza ibe yinhle kakhulu kwamanye amadivaysi. Inezici ezinhle zokwelula futhi ithambile futhi iyagobeka. I-Silicone iphinde isingatha ibanga elibanzi lokushisa futhi icindezela kancane ezintweni zikagesi uma iqhathaniswa ne-epoxy.

Lapho ukhetha i-potting material engcono kakhulu ye-electronics yakho, kufanele ucabangele okulandelayo:

Ubulukhuni bezinto ezibonakalayo. Izinhlanganisela ze-epoxy ne-urethane zinikeza isivikelo se-IP esingcono kakhulu, isimo sezulu, nokumelana nokuhuzuka ngoba zinzima uma sezilapha. I-Silicone nayo iqinile kodwa iyaguquguquka futhi ayiqinile njenge-epoxy. Cabangela ukuthi ibuphi ubulukhuni obufanela izinto zikagesi zakho bese ukhetha ngokufanele.

I-viscosity yezinto ezibonakalayo. I-viscosity ephansi isebenza ezinhlelweni eziningi ngoba izinto zokubumba ziyazilinganisa futhi zigeleza kalula njengoba kudingeka. Nokho, ungakhetha izinto zokwakha ezine-viscosity ephezulu uma izidingo zohlelo lwakho lokusebenza zisho kanjalo.

Umbala wento. Izinhlanganisela zokubumba ezicacile zinikeza ukubonakala ngisho nangemva kokwelashwa futhi zilungele izingxenye ezibalulekile ezidinga ukuhlolwa njalo. Imibala emnyama ekhanyayo ilungile kwezinye izinhlelo zokusebenza, futhi kufanele ukhethe umbala ohlangana kahle nezinto zikagesi.

Ukuqhuba kwe-thermal. Ama-Potting compounds ane-conductivity ephezulu ye-thermal ahlakaza kalula ukushisa okukhiqiza imishini kagesi. Zonke izinto ezintathu ezinkulu zokubumba zinhle kulokhu, kodwa i-silicone ithatha umqhele.

Thembela i-DeepMaterial ukuhlinzeka zonke izinhlelo zakho zokusebenza ngezinhlanganisela ezilungile nezisezingeni eliphakeme zokubumba, izinto zokunamathisela, nama-resin.
