Soldering ke tsebo ea mantlha eo setsebi se seng le se seng sa elektroniki se tlamehang ho ba le sona. Hore na o motho ea ratang ho itlosa bolutu kapa setsebi, ho bohlokoa ho tseba ho rekisa ho PCB. E u lumella ho hokahanya likarolo, ho etsa lipotoloho le ho etsa hore merero ea hau ea elektroniki e phele. Ka blog ena, re tla hlahloba mohato ka mohato oa ho solder ka PCB, hammoho le malebela le maqheka a ho fihlela sephetho sa profeshenale.
1. Bokella lisebelisoa tse hlokahalang:
Pele o qala ts'ebetso ea welding, ho bohlokoa ho bokella lisebelisoa le lisebelisoa tsohle tse hlokahalang. Sena se kenyelletsa tšepe ea solder, terata ea solder, flux, wire cutters, li-tweezers, pompo e senyang (ho ikhethela), le lisebelisoa tsa tšireletso tse kang likhalase le liatlana.
2. Lokisa boto ea PCB:
Pele lokisetsa PCB boto bakeng sa soldering. Sheba boto ea potoloho bakeng sa liphoso leha e le life kapa tšenyo 'me u netefatse hore e hloekile ebile ha e na lerōle le litšila. Haeba ho hlokahala, sebelisa joala kapa PCB cleaner ho tlosa litšila leha e le life. Hape, hlophisa likarolo 'me u tsebe sebaka sa tsona se nepahetseng botong.
3. Ho roala ka tšepe ea tšepe:
Tin plating ke mokhoa oa ho sebelisa lesela le tšesaane la solder ntlheng ea tšepe ea soldering. Sena se ntlafatsa phetisetso ea mocheso le ho etsa bonnete ba hore welding e betere. Qala ka ho futhumatsa tšepe ea soldering ho mocheso o lakatsehang. Hang ha u futhumetse, sebelisa solder e nyenyane ntlheng 'me u hlakole ho feteletseng ka seponche se mongobo kapa se hloekisang koporo.
4. Etsa kopo ea flux:
Flux ke motsoako oa bohlokoa o thusang ho solder ka ho tlosa li-oxide ho tsoa holimo le ho khothaletsa ho kolobisa hantle. Sebelisa tekanyo e nyane ea phallo ho motsoako oa solder kapa sebakeng seo motsoako o tla rekisoa ho sona.
5. Likarolo tsa welding:
Beha likarolo ho boto ea PCB ho netefatsa hore ho tsamaisana hantle. Ebe, ama tšepe ea soldering ho likarolo tse peli tse etellang pele le liphahlo. Tšoara tšepe ea soldering ka metsotsoana e seng mekae ho fihlela solder e qhibiliha 'me e phalla ho potoloha lenonyeletso. Tlosa tšepe ea tšepe 'me u lumelle motsoako oa solder hore o pholile le ho tiisa ka tlhaho.
6. Netefatsa boleng bo nepahetseng ba kopanelo:
Lekola manonyeletso a solder ho netefatsa hore ke a boleng bo holimo. Motsoako o motle oa solder o lokela ho ba le ponahalo e khanyang, e bontšang khokahanyo e matla. E boetse e lokela ho ba concave, ka mahlakoreng a boreleli le ho se be le tjheseletsa e feteletseng. Haeba ho hlokahala, sebelisa pompo ea desoldering ho tsosolosa manonyeletso leha e le afe a sa khotsofatseng le ho pheta mokhoa oa ho kopanya.
7. Ho hloekisa ka mor'a tjheseletso:
Kamora ho phethela ts'ebetso ea solder, ho bohlokoa ho hloekisa boto ea PCB ho tlosa masala a flux kapa solder spatter. Sebelisa joala ba isopropyl kapa sesepa se khethehileng sa flux le borashe e ntle ho hloekisa boto ka bonolo. Lumella ho omella ka ho feletseng pele ho etsoa liteko kapa ho sebetsa.
Ho rekisa ka PCB ho ka 'na ha bonahala ho le boima qalong, empa ka mokhoa o nepahetseng le ho itloaetsa, e fetoha tsebo e bulelang menyetla e sa feleng lefatšeng la lisebelisoa tsa elektronike. Ka ho latela ts'ebetso ea mohato ka mohato e boletsoeng ho blog ena le ho kenyelletsa malebela a khothaletsoang, o ka fihlela sephetho sa setsebi mme oa netefatsa katleho ea merero ea hau ea elektronike. Hopola, boikoetliso bo etsa hore motho a phethahale, kahoo u se ke ua nyahamisoa ke phephetso ea pele. Amohela bonono ba ho cheselletsa 'me u tlohelle boqapi ba hau bo fofa!
