Ngaba i-Electronic Potting Material inokusetyenziselwa zombini iiPCB eziqinileyo kunye neziguquguqukayo?

Izinto zokubumba nge-elektroniki kubalulekile ekuboneleleni ngokugquma kunye nokukhusela amacandelo e-elektroniki kunye neesekethe ekonakalisweni kwemiba yokusingqongileyo - ukufuma, uthuli, ukungcangcazela - kunye nokunika iPCB (iBhodi yeSekethe eShicileleyo) loo nkxaso incinci yenkxaso yoomatshini. Imalunga nokubonelela ngokuthembeka kunye nokuqina ukuphucula izixhobo zethu ze-elektroniki zemihla ngemihla.

 

Imarike inikeza uluhlu lwezinto zokubumba, nganye ineempawu ezikhethekileyo ezenza ukuba zilungele izicelo ezizodwa. I-epoxy resins izisa ukuguquguquka; i-polyurethane resins ihambisa i-thermal conductivity; Irabha ye-silicone inika ukuxhathisa kweekhemikhali ezomeleleyo, ngelixa izixhobo ze-thermoplastic zigqama ngexesha lokunyanga. Ukuqinisekisa ukuba ufumana ulungelelwano olufanelekileyo lweprojekthi yakho, qwalasela amaqondo obushushu okusebenza, amanqanaba okhuseleko okanye ezo kufuneka zibe neempawu zoomatshini.

Ngaba i-Electronic Potting Material inokusetyenziselwa zombini iiPCB eziqinileyo kunye neziguquguqukayo?

Ukuhamba ngokuthe ngqo entliziyweni yomcimbi - umntu unako imathiriyeli yeembiza ze-elektroniki ibambe eyayo ngeePCB eziqinileyo neziguquguqukayo? Ii-PCB eziqinileyo zibotshelelwe ukusuka kwizinto eziqinileyo ezifana ne-fiberglass okanye i-epoxy resin, ngelixa i-flexi-PCBs ezongezelelekileyo ziphuma kwiindlela ezithambileyo. Ngokwenene ngumahluko wobusuku nemini phakathi kwabo - ukomelela kwabo okanye ubunzima.

 

Ukulula okucacileyo okuziswe kukufumana imathiriyeli yokubumba yendalo yonke kuzo zombini kusenze sakwazi ukwenza lula inkqubo yethu yokuvelisa kakhulu, ngokukhawuleza ukucutha iindleko kunye nokunciphisa ubuthathaka bolawulo loluhlu, lonke eli xesha siqinisekisa ukuba sifumana ukusebenza okufanayo kunye nokuthembeka kuzo zonke iintlobo ezahlukeneyo zeePCB.

 

Izinto zokubumba zemveli zePCB eziqinileyo

Ukutyhubela iminyaka, iiresin ze-epoxy zibonakalise ukuba zizixhobo ezithembekileyo zokubumba kwiiPCB ezahlukeneyo eziqinileyo. Banayo yonke into: ukusuka kumandla kunye nokumelana neekhemikhali ukuya kuzinzo lobushushu kunye nokufikeleleka - izinto ezomeleleyo! Nangona kunjalo, lo mkhuseli wokupakisha weenkwenkwezi zonke unemiqobo ethile; ukuba lukhuni kunye ne-brittle kubenza bangafaneleki xa ukuguquguquka kubaluleke kakhulu, ngelixa amaqondo obushushu abo aphezulu okunyanga anokuba yingxaki ngokukhawuleza kumalungu athintela ubushushu.

 

Iintlaka zePolyurethane ziphawula ibhokisi ukuba ufuna into ethambileyo ngakumbi, ngelixa irabha ye-silicone ikhulisa iipropathi zakho zokugquma umbane kwaye ibonelela ngezivumelwano ezibalaseleyo ngeemeko zobushushu obuphezulu. Nangona zombini iinketho zinokunyusa ixabiso kancinci xa kuthelekiswa ne-epoxy resin, zisabonelela ngeenzuzo ezizodwa.

 

Imiceli mngeni ekubekeni iiPCB eziguquguqukayo

I-Potting flex PCBs yithemba elikhohlisayo - banokugoba kwaye bajike, ngoko ke izinto zokubumba kufuneka zibambe ziqinile, naphezu kwayo yonke into yokwelula kunye nokutshintsha. Ngaphezu koko, kufuneka ihlale incamathele ngokuqinileyo ngaphandle kwamadyunguza okanye amaqamza!

 

I-adhesive on flexible placements iveza umba othile, kakhulu; ukuba imathiriyeli yakho yeembiza ayihambelani nayo (okt, ayiyi kubambelela ngokufanelekileyo), uphelelwe lithamsanqa malunga nokufakwa okusebenzayo.

 

Kwaye loo nto ayingomngcipheko omncinci xa ucinga ukuba luhlobo luni lweengozi zokufuma ezinokuzisa. Umgca ongezantsi: ukuba ucwangcisa i-potting flex PCBs, ukuqinisekisa ukuba unezixhobo ezifanelekileyo kubalulekile.

 

Izinto ezilungileyo zokusebenzisa imathiriyeli yokubumba nge-elektroniki kwiiPCB eziguquguqukayo

IiPCB eziguquguqukayo ziza nesabelo sabo esilungileyo semizabalazo; nangona kunjalo, ukuba nezinto zokubumba nge-elektroniki kwicala lakho kunokuzisa iingenelo ezininzi - ukuguquguquka yeyona nto iphambili. Izinto zokubumba ze-elektroniki zenziwe ukuba zigobe kwaye zijije ngokuphindaphindiweyo ngaphandle kokuqhekeka okanye ukwahlula, ngcono kakhulu kunee-epoxy resins eziqhelekileyo. Ukuqinisekisa ukuba onke amacandelo kunye neesekethe zihlala zingonzakali nokuba ziguquguquka zinika umphetho ngaphezulu kwabanye.

 

Ukufumana ukhuseleko olongezelelekileyo kwingozi yokusingqongileyo efana nokufuma, uthuli, kunye nokungcangcazela - akukho nto ifana nemathiriyeli yokubumba ye-elektroniki! Njengoko idala ikhaka elijikeleze iindawo ezidibeneyo, amanzi anqatshelwe ukungena, ukunciphisa nayiphi na ingozi ekumdleni; kunye, ifihla ngokufihlakeleyo ukungcangcazela, nto leyo inceda ukunciphisa umonakalo obangelwa kuxinzelelo lomatshini.

 

Izinto zokubumba ze-elektroniki zibalasele xa zidityaniswe neendidi ezahlukeneyo zesubstrates – i-polyimide kunye ne-polyester-derived flexible PCB, umzekelo- zincamathele ngokulula ngenxa yendalo yazo encamathelayo. Oku kuvelisa uxhulumaniso oluthembekileyo phakathi kwee-substrates zombini, ukuthintela ukwahlukana nakweyiphi na indleko.

 

Umahluko phakathi kwe-PCB eqinile kunye neguquguqukayo

Eqinile kwaye ebhetyebhetye PCBs ubusuku nemini-enye yomelele njengelitye, enye igobile njengenyoka. Izinto ezenziwe ngazo zichaphazela iipropati zabo ngeendlela ezithile ezimangalisayo. Ukuba ufumana i-drift yam, into esebenzela iibhodi eziqinileyo ayizukwenza kwizinto eziguquguqukayo.

 

Le yantlukwano ithetha ukuba ukuchola imbiza yembiza akukho lula: ukhetho lwakho luya kuxhomekeka kakhulu kwindlela engqongqo okanye egobile ngayo xa yonke into ithethwa kwaye yenziwe! Ngamanyathelo ekufuneka ahlale omelele-cinga iiPCB zohlobo oluqinileyo-sidinga into enika ukomelela koomatshini kunye nokhuseleko olongezelelweyo ngokuchasene nokwenzakala kokusingqongileyo.

 

Kodwa apho ukuguquguquka kubaluleke kakhulu, siya kufuna into ethambileyo ukuze simelane nokujija ngokuphindaphindiweyo ngaphandle kokunikezela kumonakalo.

 

Okokugqibela, sisindise ingcinga malunga nokumelana nobushushu, nathi. Kwangaxeshanye, iimeko ezishushu kakhulu zisenokungatyhafi imathiriyeli eqinile; abazala babo ababonelelayo abanakuthatha ubushushu obuninzi, ngoko khetha amaqondo obushushu okunyanga ngokufanelekileyo okanye ulindele iziphumo ezingaphantsi kunezilungileyo xa zigqityiwe.

 

Uvavanyo kunye nokuqinisekiswa kwezinto zokubumba nge-elektroniki kwii-PCB eziguquguqukayo

Uvavanyo kunye nokuqinisekiswa kubalulekile ekuqinisekiseni ukusebenza kakuhle kwezinto zokubumba nge-elektroniki ezisetyenziswa kwiiPCB eziguquguqukayo. Ukufumana umqheba kwiintsilelo zezinto eziphathekayo kunceda ukuqinisekisa ukuba iyahlangabezana nayo yonke imigangatho eyimfuneko.

 

Uvavanyo lokuhamba ngebhayisikile eshushu yindlela eqinisekileyo yokuvavanya ukuthembeka kwezi zinto phantsi komgangatho ohlukeneyo wobushushu. Kusivumela ukuba sikhuphe izakhono - okanye ukunqongophala kwazo - ezinokuthi zingabonakali ngenye indlela.

 

Uvavanyo lokuguquguquka kwakhona kufuneka lwenziwe malunga neePCBs ezijoliswe ukugoba okanye ukugoba ngexesha lokusetyenziswa! Oku kunceda ukufumanisa ukuba ezo ziqwenga ziyakwazi ukuphatha ukugoba ngokuphindaphindiweyo ngaphandle kokubonisa umonakalo njengokuqhekeka okanye i-delamination.

 

Okokugqibela, kukwakho novavanyo lokuxhathisa ukufuma, uvavanyo lokumelana neekhemikhali kunye novavanyo lokugquma umbane njengezinto ezibalulekileyo zokumisela ukuba ezi zinto zinokukhusela ngokwaneleyo na kwiziphumo ezinjengokungena kwamanzi.

Amagama okugqibela

Izinto zokubumba nge-elektroniki inyakamisa indlu ngenxa yeePCB eziguquguqukayo neziguquguqukayo. Ngelixa izinto ze-goopy zesikolo esidala zazisoyikeka kwiiPCB ezingaguquguqukiyo, azizukuyisika ngezinto ezinokugobeka. Izinto zokubumba ze-elektroniki zinokwenza konke-zinika ukuguquguquka okumangalisayo kunye nokuqina okuhlangabezana neemfuno zebhodi nganye.

 

Olu hlobo lwezinto luhlawula ngenxa yokuba ufumana ukhuseleko olungenakulinganiswa nokuphazamiseka kokusingqongileyo, akukho miba yokuhambelana (enkosi kuluhlu olubanzi lwee-substrates) kunye nokuthembeka kwe-stellar super. Nangona ezinye iihiccups ezifana namaqamza omoya okanye imiba yokuncamathela inokuvela ngokufutshane kuhambo lwakho lwe-PCB, zibethe ngomva ngovavanyo oluthile ngaphambi kokuba zibe nzulu.
