Pcb sebetsa prototype boto 94v-0 Halogen-mahala potoloho boto

Tekanyo ea mollo ea boto ea potoloho e hatisitsoeng e bua ka tekanyo ea mollo oa boto. Hangata liboto tsa potoloho tse hatisitsoeng li entsoe ka thepa ea fiber ea khalase e nang le tekanyo ea mollo ea FR-4. Thepa ena e na le tekanyo e phahameng ea mollo 'me e ka thibela mollo ho isa tekanyong e itseng. Ha e le hantle, ho ea ka lintlha tse kang litlhoko tsa kopo le litlhoko tsa polokeho, tekanyo ea mollo ea liboto tsa potoloho e hatisitsoeng e ka boela ea amohela lisebelisoa le litekanyetso tse ling tse fapaneng.

Tekanyetso e khethehileng ea UL94v0 ke hore boto ea potoloho e fihlile boemong ba ho thibela mollo. Teko ea ho chesa lisebelisoa tsa UL94 le lisebelisoa tsa lisebelisoa tsa polasetiki tse nang le lebitso le tloaelehileng, boholo ba ts'ebeliso, likarolo tsa sehlopha, litekanyetso tse amanang, joalo-joalo Teko ea ho tuka ha thepa ea polasetiki ea UL94 - Sehlopha:
