Ingabe I-Electronic Potting Material Ingasetshenziswa Kokubili Ama-PCB Aqinile Futhi Aguquguqukayo?

Izinto zokubumba nge-elekthronikhi kubalulekile ukuze kuhlinzekwe izinto ezifakwa ngaphakathi nokuvikela izingxenye ze-elekthronikhi kanye nokujikeleza emazingeni emvelo alimazayo - umswakama, uthuli, ukudlidliza - kanye nokunika i-PCB (Ibhodi Lesifunda Eliphrintiwe) lokho kusekelwa okwengeziwe kwemishini. Konke kumayelana nokunikeza ukwethembeka nokuqina ukuze kuthuthukiswe izinto zethu zansuku zonke zikagesi.

 

Imakethe inikeza uhla lwezinto zokubumba, ngayinye enezindawo ezikhethekile ezizenza zifanelekele izinhlelo zokusebenza eziyingqayizivele. Ama-epoxy resins aletha ukuguquguquka; ama-polyurethane resins ahlinzeka nge-thermal conductivity; Irabha ye-silicone inikeza ukumelana kwamakhemikhali okuqinile, kuyilapho izinto ze-thermoplastic zigqama ngesikhathi sokwelapha. Ukuqinisekisa ukuthi uthola okulingana kahle kwephrojekthi yakho, cabanga ngamazinga okushisa okusebenza, amazinga okuvikela noma lezo zimpawu okufanele zibe nazo.

Ingabe I-Electronic Potting Material Ingasetshenziswa Kokubili Ama-PCB Aqinile Futhi Aguquguqukayo?

Ukuya ngqo kumnyombo wendaba - kungaba umuntu i-electronic potting material ibambe owayo ngama-PCB aqinile futhi aguquguqukayo? Ama-PCB aqinile ahlanganiswe kusuka ezintweni eziqinile njenge-fiberglass noma i-epoxy resin, kuyilapho ama-flexi-PCB atholakalayo ephuma kuzinto ezisebenziseka kalula. Ngempela umehluko wobusuku nemini phakathi kwabo - ukuqina noma ubulukhuni babo.

 

Ukunethezeka okusobala okulethwe ngokuthola izinto zokubumba ezitholakala emhlabeni wonke kubo bobabili kusinikeze ikhono lokwenza inqubo yethu yokukhiqiza ibe lula kakhulu, ukunqamula izindleko kanye nokunciphisa izinkinga zokuphathwa kwempahla, konke ngesikhathi siqinisekisa ukuthi sithola ukusebenza okungaguquki nokwethembeka kuzo zonke izinhlobo ezihlukene zama-PCB.

 

Izinto zokubumba zendabuko zama-PCB aqinile

Ngokuhamba kweminyaka, ama-epoxy resins afakazele ukuthi ayinto ethembekile yokubumba ama-PCB ahlukahlukene aqinile. Banakho konke: kusukela emandleni kanye nokumelana namakhemikhali kuya ekuzinzeni kokushisa nokufinyeleleka kalula - izinto eziqinile! Nokho, lesi sivikeli sokupakisha sezinkanyezi zonke sinezihibe ezithile; ukuqina nokuqina kubenza bangafaneleki lapho ukuguquguquka kubalulekile, kuyilapho amazinga abo okushisa aphezulu okuphulukisa angaba yinkinga ngokushesha ngezingxenye ezizwela ukushisa.

 

Ama-polyurethane resins afaka uphawu ebhokisini uma udinga okuthile okuthambile kakhudlwana, kuyilapho irabha ye-silicone ikhulisa izakhiwo zakho zokuhlukanisa ugesi futhi inikeza amadili amahle kakhulu ezimweni ezishisa kakhulu. Nakuba zombili izinketho zingase zinyuse intengo kancane uma ziqhathaniswa ne-epoxy resin, zisanikeza izinzuzo eziyingqayizivele.

 

Izinselele ekubumbeni ama-PCB aguquguqukayo

Ama-PCB aguquguqukayo e-Potting kuyithemba elikhohlisayo - angagoba futhi asonte, ngakho-ke impahla yobumba idinga ukubambelela iqinile, ngisho naphezu kwakho konke lokho kunwebeka nokuguquguquka. Futhi, kufanele ihlale inamathele iqinile ngaphandle kwamabhamuza noma amabhamuza!

 

I-adhesive ekubekweni okuguquguqukayo iveza inkinga, futhi; uma impahla yakho yokubumba ingahambisani nayo (okungukuthi, ngeke ibambelele kahle), uphelelwe yinhlanhla mayelana nokuhlanganisa okusebenzayo.

 

Futhi lokho akuyona ingozi encane uma ucabangela ukuthi hlobo luni lwezingozi ezingalethwa umswakama oqhubekayo. Ngezansi: uma uhlela ukufaka ama-PCB aguquguqukayo, ukuqinisekisa ukuthi unezinto ezifanele kubalulekile.

 

Izinzuzo zokusebenzisa i-electronic potting material yama-PCB aguquguqukayo

Ama-PCB aguquguqukayo eza nengxenye yawo efanelekile yemizabalazo; noma kunjalo, ukuba ne-electronic potting material ohlangothini lwakho kungaletha izinzuzo eziningana - ukuguquguquka kube yiyona eyinhloko. Izinto zokubumba ze-elekthronikhi zenziwa ukuthi zigobe futhi zisonteke ngokuphindaphindiwe ngaphandle kokuqhekeka noma ukuhlukana, okungcono kakhulu kunezinhlaka ze-epoxy zendabuko. Ukuqinisekisa ukuthi zonke izingxenye kanye nokujikeleza kuhlala kungalimali ngisho nalapho kuguquguquka kukunikeza umkhawulo ngaphezu kwezinye.

 

Ukuze uthole ukuvikeleka okwengeziwe ekulimaleni kwemvelo okunjengomswakama, uthuli, nokudlidliza - ayikho into efana ne-electronic potting material! Njengoba idala isivikelo ezingxenyeni ezihlangene, amanzi anqatshelwa ukungena, anciphisa noma iyiphi ingozi ekugqwaleni; futhi, ifihla ukudlidliza ngobuqili, okusiza ukunciphisa umonakalo obangelwa ukucindezeleka kwemishini.

 

Izinto zokubumba ze-elekthronikhi ziyagqama uma zibhangqwe nezinhlobo ezahlukene zama-substrates - i-polyimide ne-polyester-derived flexible PCB, isibonelo- zinamathela kalula ngenxa yemvelo yazo yokunamathela. Lokhu kukhiqiza ukuxhumana okuthembekile phakathi kokubili kwama-substrates, ukuvimbela ukuhlukana nganoma yiziphi izindleko.

 

Umehluko phakathi kwama-PCB aqinile navumelana nezimo

Ama-PCB aqinile futhi avumelana nezimo cishe ubusuku nemini - enye iqine njengetshe, enye igoba njengenyoka. Izinto ezenziwe ngazo zithinta izakhiwo zazo ngezindlela ezithile ezimangalisayo. Uma uthola i-drift yami, lokho okusebenzela amabhodi aqinile ngeke kukwenze kuzinto eziguquguqukayo.

 

Lo mehluko usho ukuthi ukukhetha imbiza akulula: ukukhetha kwakho kuzoncika kakhulu ekutheni kumele kube lukhuni kangakanani noma kugobe kangakanani uma konke sekushiwo futhi kwenziwa! Ngezinyathelo okufanele zihlale ziqinile - cabanga ama-PCB ohlobo oluqinile - sidinga okuthile okunikeza ukuqina komshini ngokuzivikela okwengeziwe ekulimaleni kwemvelo.

 

Kodwa lapho ukuguquguquka kubaluleke kakhulu, sizofuna okuthile okuthambile ukuze simelane nokusonteka okuphindaphindiwe ngaphandle kokunqotshwa umonakalo.

 

Okokugcina, sisindise umcabango mayelana nokumelana nezinga lokushisa, futhi. Ngesikhathi esifanayo, izimo ezishisa kakhulu zingase zingafihli izinto eziqinile; abazala babo abahlinzeki bempahla abakwazi ukuthatha ukushisa okuningi, ngakho khetha amazinga okushisa okuphilisa ngokufanele noma ungalindela imiphumela engaphansi kunaleyo eyiyona uma sekuqediwe.

 

Ukuhlolwa nokuqinisekiswa kwezinto zokubumba zikagesi zama-PCB aguquguqukayo

Ukuhlola nokuqinisekisa kubalulekile ukuze kuqinisekiswe ukusebenza kahle kwezinto zokubumba zikagesi ezisetshenziswa kuma-PCB aguquguqukayo. Ukuthola isibambo semikhawulo engaba khona yezinto kusiza ukuqinisekisa ukuthi ihlangabezana nazo zonke izindinganiso ezidingekayo.

 

Ukuhlolwa kokuhamba ngebhayisikili okushisayo kuyindlela eqinisekile yokuhlola ukwethembeka kwalezi zinto ngaphansi kwamazinga okushisa ahlukene. Kusivumela ukuthi sikhiphe amakhono - noma ukuntuleka kwawo - okungenzeka ukuthi awazange adalulwe ngenye indlela.

 

Ukuhlolwa kokuguquguquka nakho kufanele kwenziwe mayelana nama-PCB enzelwe ukugoba noma ukugoba ngesikhathi sokusetshenziswa! Lokhu kusiza ekunqumeni ukuthi lezo zingcezu zingakwazi yini ukugoba ngokuphindaphindiwe ngaphandle kokubonisa umonakalo njengokuqhekeka noma i-delamination.

 

Okokugcina, kukhona nokuhlola ukumelana nomswakama, ukuhlola ukumelana namakhemikhali kanye nokuhlolwa kokufakwa kukagesi njengezingxenye ezibalulekile zokunquma ukuthi lezi zinto zingavikela ngokwanele yini emiphumeleni enjengokungena kwamanzi.

Amagama Okugcina

Izinto zokubumba nge-elekthronikhi inyakazisa indlu ngenxa yama-PCB angaguquki futhi aguquguqukayo. Ngenkathi izinto ze-goopy zesikole esidala zazimangalisa kuma-PCB angaguquki, ngeke zisike ngezigobekayo. Izinto zokubumba zikagesi zingakwenza konke—zinikeze ukuguquguquka okumangalisayo nokuqina okuhlangabezana nezidingo zebhodi ngalinye ngqo.

 

Lolu hlobo lwezinto luyakhokha ngoba uthola ukuvikeleka okungenakunqotshwa ekuphazanyisweni kwemvelo, azisekho izinkinga zokusebenzisana (sibonga uhlu lwazo olubanzi lwama-substrates) nokuthembeka okukhulu kwenkanyezi. Noma ezinye izihibe njengamabhamuza omoya noma izinkinga zokunamathela zingavela kafushane ohambweni lwakho lwe-PCB, zibuyisele emuva ngokuhlolwa okuthile ngaphambi kokuthi zibe bucayi.
