Bofokoli ba PCB le Taolo ea Boleng, ha re ntse re loanela ho boloka maemo a holimo a boleng le katleho, ho bohlokoa ho rarolla le ho fokotsa liphoso tsena tse tloaelehileng tsa tlhahiso ea PCB.
Sethaleng se seng le se seng sa tlhahiso, ho ka ba le mathata a bakang mefokolo ho boto ea potoloho e felileng.Mefokolo e tloaelehileng e kenyelletsa ho cheselletsa, ho senyeha ha mochini, ho silafala, ho se nepahale ha litekanyo, liphoso tsa plating, likarolo tse ka hare tse sa lumellaneng hantle, mathata a ho cheka le mathata a thepa.
Litšitiso tsena li ka lebisa ho lipotoloho tse khutšoane tsa motlakase, li-circuits tse bulehileng, botle bo bobe, ts'epo e fokotsehileng, le ho hloleha ho felletseng ha PCB.
Bofokoli ba moralo le phapang ea tlhahiso ke lisosa tse peli tse kholo tsa liphoso tsa PCB.
Mona ke tse ling tsa lisosa tse kholo tsa liphoso tse tloaelehileng tsa tlhahiso ea PCB:
1.Moqapi o sa nepahalang
Litšitiso tse ngata tsa PCB li bakoa ke mathata a moralo.Mabaka a tloaelehileng a amanang le moralo a kenyelletsa sebaka se sa lekaneng pakeng tsa mela, li-loops tse nyenyane tse pota-potileng borehole, li-angles tse bohale tse fetang bokhoni ba tlhahiso, le ho mamella mela e mesesaane kapa likheo tse ke keng tsa finyelloa ke mokhoa oa tlhahiso.
Mehlala e meng e kenyelletsa lipaterone tsa symmetrical tse behang kotsi ea maraba a acid, mesaletsa e metle e ka senyehang ke ho tsoa ha electrostatic, le litaba tsa ho qhala mocheso.
Ho etsa tlhahlobo e felletseng ea Design for Manufacturability (DFM) le ho latela litataiso tsa moralo oa PCB ho ka thibela mefokolo e mengata e bakiloeng ke moralo.
Ho kenyelletsa lienjineri tsa tlhahiso tšebetsong ea meralo ho thusa ho lekola bokhoni ba tlhahiso.Lisebelisoa tsa ho etsisa le ho etsa mohlala li ka boela tsa netefatsa mamello ea moralo ho khatello ea maikutlo ea lefats'e le ho tseba libaka tse nang le mathata.Ho ntlafatsa moralo oa tlhahiso ke mohato oa pele oa bohlokoa oa ho fokotsa liphoso tse tloaelehileng tsa tlhahiso ea PCB.
2.PCB tšilafalo
Ho etsa PCB ho kenyelletsa tšebeliso ea lik'hemik'hale tse ngata le mekhoa e ka lebisang tšilafalo.Nakong ea ts'ebetso ea tlhahiso, PCBS e silafatsoa habonolo ke lisebelisoa tse kang masala a flux, oli ea menoana, tharollo ea acid plating, lithōle tsa likaroloana le masala a ho hloekisa.
Litšila li beha kotsi ea li-circuits tse khutšoane tsa motlakase, li-circuits tse bulehileng, bofokoli ba li-welding le mathata a nako e telele a kutu.Fokotsa kotsi ea tšoaetso ka ho boloka libaka tsa tlhahiso li hloekile haholo, ho tiisa taolo e tiileng ea tšilafalo, le ho thibela ho kopana le batho.Koetliso ea basebetsi mabapi le mekhoa e nepahetseng ea ho sebetsana le eona ke ea bohlokoa.
3.bofokoli ba lintho tse bonahalang
Lisebelisoa tse sebelisoang ha ho etsoa PCB li tlameha ho se be le bofokoli ba tlhaho.Lisebelisoa tsa PCB tse sa lumellaneng (tse kang laminates tsa boleng bo tlaase, prepregs, foil, le likarolo tse ling) li ka 'na tsa e-na le likoli tse kang resin e sa lekaneng, li-protrusions tsa khalase, li-pinholes le li-nodule.
Litšitiso tsena tsa thepa li ka kenyelletsoa letlapeng la ho qetela 'me tsa ama ts'ebetso.Ho netefatsa hore lisebelisoa tsohle li tsoa ho barekisi ba tšepahalang ba nang le taolo e pharalletseng ea boleng ho ka thusa ho qoba litaba tse amanang le thepa.Ho boetse ho khothaletsoa ho hlahloba lisebelisoa tse kenang.
Ntle le moo, ts'enyo ea mochini, phoso ea motho le liphetoho tsa ts'ebetso le tsona li ka ama tlhahiso ea li-pcb.
Litšitiso li etsahala tlhahisong ea PCB ka lebaka la moralo le lintlha tsa tlhahiso.Ho utloisisa mefokolo e atileng haholo ea PCB ho nolofalletsa lifeme ho tsepamisa maikutlo ho liteko tse lebisitsoeng tsa thibelo le tlhahlobo.Melao-motheo ea tlhokomeliso ke ho etsa tlhahlobo ea moralo, lits'ebetso tsa ho laola ka thata, basebetsi ba literene, ho hlahloba ka botlalo, ho boloka bohloeki, liboto tsa pina le melao-motheo ea bopaki ba liphoso.
