Liaparo tsa PCB (Printed Circuit Board) li phetha karolo ea bohlokoa ho sireletseng lipotoloho libakeng tse thata tsa kantle. Leha ho le joalo, maemong a mang, ho ka 'na ha hlokahala ho tlosa barbotage PCB bakeng sa merero tokiso kapa phetolo. Tataisong ena e akaretsang, re tla u tsamaisa mehatong ea ho tlosa likhoele tsa PCB ka mokhoa o sireletsehileng le ka katleho. Ka mokhoa o nepahetseng le lisebelisoa, o ka tlosa seaparo ka katleho ntle le ho baka tšenyo leha e le efe ho potoloho e bonolo.
1. Utloisisa ho roala ha PCB
Pele u ikakhela ka setotsoana ts'ebetsong ea ho tlosa, ho bohlokoa ho utloisisa mefuta ea liphahlo tsa PCB tseo u ka kopanang le tsona. Liaparo tse tloaelehileng li kenyelletsa acrylic, epoxy, polyurethane, silicone le parylene. Mofuta o mong le o mong o na le litšobotsi tsa oona mme o hloka mekhoa e khethehileng ea ho tlosa. Pele o qala ts'ebetso ea ho tlosa, ho bohlokoa ho tseba ho roala ho sebelisitsoeng ho PCB ho netefatsa hore ho sebelisoa mokhoa o nepahetseng.
2. Mehato ea Tšireletso
Tšireletseho e lokela ho ba ntho e tlang pele bophelong ba hau ha u sebetsa ka liphahlo tsa PCB. Etsa bonnete ba hore o roala likhalase, liatlana, le maske a ho hema ho itšireletsa mosing oa lik'hemik'hale. Hape, sebetsa sebakeng se nang le moea o motle ho fokotsa monyetla oa ho pepesehela lintho tse kotsi. Boloka setima-mollo haufi 'me u latele litataiso tsohle tsa polokeho le litaelo tse fanoeng ke moetsi oa pente.
3. Khetha sesebelisoa se nepahetseng
Ho tlosa ka katleho coating PCB, o hloka sete e khethehileng ea lisebelisoa. Tsena li ka kenyelletsa liteishene tsa ho tsosolosa moea o chesang, lithunya tse futhumatsang, litšepe tsa tšepe, lithipa tse nepahetseng, le lisebelisoa tsa ho hloekisa PCB. Khetho ea sesebelisoa e itšetlehile ka mofuta oa ho roala le boholo ba sebaka seo u batlang ho se tlosa.
4. Ts'ebetso ea ho hlakola mohato ka mohato
- Mohato oa 1: Lokisetsa PCB ka ho tlosa likaroloana, likhokahano kapa lithapo tse ka sitisang ts'ebetso ea ho tlosa litlolo.
- Mohato oa 2: Fumana mofuta oa ho roala. Liaparo tsa Acrylic le epoxy hangata li ka nolofatsoa le ho tlosoa ho sebelisoa sethunya sa mocheso kapa seteishene sa ho tsosolosa moea o chesang. Liaparo tsa silicone kapa tsa parylene, ka lehlakoreng le leng, li ka hloka li-strippers tsa lik'hemik'hale kapa li-solvents tse khethehileng.
- Mohato oa 3: Ka bonolo futhumatsa seaparo ka mokhoa o loketseng, ho etsa bonnete ba hore u se ke ua chesa kapa ua senya PCB.
- Mohato oa 4: U sebelisa thipa e nepahetseng kapa sesebelisoa se seng se loketseng, hlakola seaparo se bonolo ka hloko. Ela hloko hore u se ke ua senya potoloho e ka tlaase.
- Mohato oa 5: Ka mor'a ho tlosa boholo ba ho roala, sebelisa tharollo ea ho hloekisa ea PCB ho tlosa mesaletsa leha e le efe kapa mesaletsa ea masala.
- Mohato oa 6: Hlatsoa PCB hantle ka isopropanol kapa metsi a deionized ho tlosa masala a tharollo ea ho hloekisa.
- MOHATO 7: Lumella PCB ho omella ka ho feletseng pele e kopanya kapa ho etsa mosebetsi ofe kapa ofe o mong.
5. Litlhokomeliso ka mor'a ho hlakoloa
Ka mor'a katleho PCB barbotage ho tloswa, ke habohlokoa ho hlahloba boto bakeng sa tšenyo leha e le efe e ka bang teng. Lekola mesaletsa efe kapa efe e phahamisitsoeng kapa e senyehileng, li-vias tse robehileng, kapa likarolo tse senyehileng. Haeba mathata leha e le afe a fumanoa, a lokela ho lokisoa pele a tsoela pele ka mosebetsi o mong.
Ho tlosa pente ea PCB ho hloka mamello, ho nepahala le lisebelisoa tse nepahetseng. Ka ho latela mokhoa oa mohato ka mohato o boletsoeng tataisong ena, o ka tlosa li-coatings ka mokhoa o sireletsehileng le ka katleho ho tsoa ho li-PCB. Hopola ho ba hlokolosi, ho latela litataiso tsa polokeho, le ho nka mehato e hlokahalang kamora ho qhaqhoa ho netefatsa bots'epehi ba potoloho. Thabile ho tloswa ha koae!
