Mokhoa oa ho rala PCBS ea sesole le ea ho fofa

Ha li bapisoa le liboto tse tloaelehileng, li-PCBS li bolela hore lits’ebetso tsa sesole le tsa Aerospace li hloka ts’ebetso e khethehileng ho moralo, tlhahiso le kopano.

Ha u bokella PCBS bakeng sa ts’ebeliso ea sesole le ea ho fofa, likarolo tse ling li tlameha ho kenyelletsoa. E meng ea eona e kenyelletsa:

L Sebelisa moemeli oa mocheso ha ho hlokahala.

L Eketsa tšireletso le motheo o mong ho wiring e mahlonoko.

L Coat PCBS e nang le boleng bo holimo ba fafatsa ea acrylic ho ba sireletsa maemong a senyehang.

Sebelisa likarolo tse nang le litlhaloso tsa sesole ho fapana le likarolo tsa khoebo.

L Sebelisa mekhoa e loketseng ea ho emisa.

L Khetha ka hloko lisebelisoa le likarolo ho mamella mocheso o phahameng. Tsena li kenyelletsa Pyralux AP, epoxy laminates (mohlala, FR408) le lisebelisoa tse fapaneng tsa mantlha tsa tšepe.

L Sebelisa thepa ea ho qetela e tšepahalang ho matlafatsa ts’ireletso maemong a thata. Lisebelisoa tse tloaelehileng haholo tsa khabiso tse sebelisoang kopanong ea sesole le ea ho fofa ea lifofane li kenyelletsa:

L E hlahisa maemo a sesole le a lifofane PCBS e lumellanang le mil-PRF-31032, MIL-PRF-50884 le MIL-PRF-55110 litekanyetso.

L Ka kopo netefatsa matla a koba, matla a tlamo, bophara ba terata, botenya, qeto, botenya ba seaparo se sireletsang le dielectric hantle pele e romelloa. Etsa bonnete ba hore u ikemiselitse ho li sebelisa libakeng tse thata tsa indasteri.

Ho boloka boleng le ho tšoarella ho bohlokoa ha ho raloa PCBS ea sesole le ea ho fofa. Ho hloleha ha PCB ho ka ama ts’ebetso ea ts’ebeliso mme ka hona katleho ea sepheo ka kakaretso.
