Mokhoa oa ho hlahloba ka mahlo
Ho sebelisoa khalase e holisang (X5) kapa microscope ea optical ho PCBA, boleng ba tlhoekiso bo hlahlojoa ka ho ela hloko boteng ba masala a tiileng a solder, manya le lifaha tsa thini, likaroloana tsa tšepe tse sa tsitsang le litšila tse ling.Hangata ho hlokahala hore karolo ea PCBA e lokela ho hloeka ka hohle kamoo ho ka khonehang le hore ha ho na mesaletsa ea masala kapa litšila tse lokelang ho bonahala.Sena ke sesupo sa boleng mme hangata se lebisitswe ho ditlhoko tsa mosebedisi, ditekanyetso tsa bona tsa ho ahlola diteko le palo ya kgolo e sebediswang nakong ya tlhahlobo.Mokhoa ona o khetholloa ka mokhoa o bonolo le bonolo oa tšebeliso.Phoso ke hore ha ho khonehe ho hlahloba litšila tse ka tlase ho likarolo le litšila tse setseng tsa ionic mme li loketse lits'ebetso tse sa hlokeng letho.
Mokhoa oa ho Rarolla Mokelikeli
Mokhoa oa ho ntša solvent o boetse o tsejoa e le tlhahlobo ea li-ionic contaminant content.Ke mofuta oa tlhahlobo ea karolelano ea litšila ea ionic, tlhahlobo e sebelisoa hangata mokhoa oa IPC (IPC-TM-610.2.3.25), e hloekisoa PCBA, e qoelisoa ka tharollo ea tlhahlobo ea tlhahlobo ea tšilafalo ea tekanyo ea ionic (75% ± 2% isopropyl e hloekileng). joala hammoho le 25% ea metsi a DI), masala a ionic a tla qhibiliha ka har'a motsoako, a bokelle solvent ka hloko, a tsebe ho hanyetsa ha eona.
Litšila tsa ionic hangata li tsoa linthong tse sebetsang tsa solder, joalo ka li-ion tsa halogen, li-ion tsa asiti, le li-ion tsa tšepe tse tsoang ho kutu, 'me liphetho li hlahisoa e le palo ea sodium chloride (NaCl) e lekanang sebakeng ka seng.Ke hore, kakaretso ea litšila tsena tsa ionic (ho kenyeletsoa feela tse ka qhibilihang ka har'a solvent) e lekana le palo ea NaCl, eseng hakaalo kapa e teng feela holim'a PCBA.
Teko ea Resistance Insulation Test (SIR)
Mokhoa ona o lekanya ho hanyetsa ha li-insulation tsa holim'a li-conductor ho PCBA.Tekanyo ea khanyetso ea ho itšireletsa ka holim'a metsi e bonts'a ho lutla ka lebaka la tšilafalo tlasa maemo a fapaneng a mocheso, mongobo, motlakase le nako.Melemo ke tekanyo e tobileng le ea bongata;le ho ba teng ha libaka tsa libaka tsa solder peista ka lemoha.E le masala flux PCBA solder peista e haholo-holo teng ka seam pakeng tsa sesebediswa le PCB, haholo-holo ka solder manonyeletso a BGAs, tse thata ho feta ho tlosa, e le hore ho ka ho eketsehileng netefatsa ho hloekisa phello, kapa ho netefatsa polokeho. (Ts'ebetso ea motlakase) ea peista ea solder e sebelisitsoeng, tekanyo ea ho hanyetsa holimo ka har'a seam pakeng tsa motsoako le PCB hangata e sebelisoa ho hlahloba phello ea ho hloekisa ea PCBA.
Maemo a kakaretso a tekanyo ea SIR ke teko ea lihora tse 170 mochesong oa 85°C, mongobo o leng teng oa 85% RH le leeme la 100V.
