Re Sebelisa Melao e Mene ea Moralo e sa Buisanoeng
Sesebelisoa se seng le se seng sa laser welding seo re se tlisang se latela melao ena e netefalitsoeng tšimong:
Thermal Decoupling: Lisebelisoa tsa ho lokisa li sebelisa lisebelisoa tse tlaase tsa conductivity tse kang G10 fiberglass kapa PEEK e tletseng ceramic moo ho fetisa mocheso o tobileng ho lokelang ho fokotsoa.
