Habka kormeerka muuqaalka
Isticmaalka muraayadda weynaynta (X5) ama mikroskoob indhaha PCBA, tayada nadiifinta waxaa lagu qiimeeyaa iyadoo la eegayo joogitaanka haraaga adag ee alxanka, wasakhda iyo daasadaha, walxaha birta ah ee aan la hagaajin iyo wasakh kale.Caadi ahaan waxa loo baahan yahay in dusha PCBA-gu uu ahaado mid nadiif ah intii suurtogal ah iyo in aan la arki karin wax raad ah oo hadhaa ah ama wasakhaysan.Kani waa tilmaame tayo leh waxaana inta badan lagu beegsadaa shuruudaha isticmaalaha, shuruudaha qiimaynta imtixaankooda iyo tirada waynaynta ee la isticmaalo inta lagu jiro kormeerka.Habkan waxaa lagu gartaa fududaantiisa iyo sahlanaanta isticmaalka.Khasaaraha ayaa ah in aysan suurtagal ahayn in la hubiyo wasakhowga hoose ee qaybaha iyo haraaga sunta ionic oo ku habboon codsiyada aan baahida lahayn.
Habka Soo saarista dareeraha
Habka soo saarista dareeraha waxaa sidoo kale loo yaqaannaa baaritaanka ka kooban sunta ionic.Waa nooc ka mid ah imtixaanada iskucelceliska maadada wasakhaysan ee ionic, imtixaanka guud ahaan waxaa loo isticmaalaa habka IPC (IPC-TM-610.2.3.25), waa la nadiifiyaa PCBA, la jeexjeexay xalka tijaabada wasakhowga heerka ionic (75% ± 2% isopropyl saafi ah khamriga iyo 25% biyaha DI), hadhaaga ionic ayaa lagu milmi doonaa dareeraha, si taxadar leh u ururi dareeraha, go'aamiso iska caabintiisa
Wasakhda Ionic waxaa inta badan laga soo qaadaa walxaha firfircoon ee alxanka, sida halogen ions, ion acid, iyo aions biraha daxalka, natiijooyinka waxaa lagu muujiyay tirada sodium chloride (NaCl) oo u dhiganta halkii unug.Taasi waa, wadarta cadadka wasakhaysan ionic (oo ay ku jiraan kaliya kuwa lagu milmi karo dareeraha) waxay u dhigantaa qadarka NaCl, maahan daruuri ama gaar ahaan dusha PCBA.
Tijaabada Iska-caabbinta Dusha sare (SIR)
Habkani waxa uu cabbiraa iska caabbinta dahaarka dusha sare ee u dhexeeya daarayaasha PCBA-ga.Cabbiraadda caabbinta dahaarka dusha sare waxay muujinaysaa daadinta ay sabab u tahay wasakheynta xaaladaha kala duwan ee heerkulka, qoyaanka, tamarta iyo waqtiga.Faa'iidooyinka waa cabbir toos ah iyo cabbir;iyo joogitaanka meelaha gudaha ee koollada alxanka ah waa la ogaan karaa.Maaddaama qulqulka hadhaaga ah ee koollada alxanka PCBA ay inta badan ku jiraan tollaynta u dhaxaysa aaladda iyo PCB-ga, gaar ahaan kala-goysyada alxanka ee BGA-yada, kuwaas oo aad u adag in la saaro, si loo sii xaqiijiyo saamaynta nadiifinta, ama loo xaqiijiyo badbaadada. (waxqabadka korantada) ee koollada alxanka ee la isticmaalo, cabbirka caabbinta dusha sare ee tollaynta u dhaxaysa qaybta iyo PCB-ga waxaa badanaa loo isticmaalaa si loo hubiyo saamaynta nadiifinta PCBA
Xaaladaha cabirka SIR ee guud waa 170 saacadood oo tijaabo ah heerkulka deegaanka 85°C, 85% RH qoyaanka deegaanka iyo eexda cabbirka 100V.
