STD Standard Copper Foil

●makulidwe: 12um 15um 18um 35um 70um 105um 140um

●Standard m'lifupi: 1290mm, akhoza kudula monga pempho kukula

●Phukusi la bokosi lamatabwa

Tsatanetsatane wa Zamalonda

Zolemba Zamalonda

Mndandanda wa STD ndi zojambula zamkuwa za IPC giredi 1 zomwe zimagwiritsidwa ntchito ngati gawo lakunja la matabwa olimba.Imapezeka mu makulidwe oyambira pa 12 µm mpaka kufika pa makulidwe a ED a 140 µm.Ichi ndi chojambula chokhacho cha ED chomwe chimapezeka mu makulidwe a 105 µm ndi 140 µm, kupangitsa kuti ikhale yabwino kwa matabwa opangidwa ngati masinki otentha kapena kuyendetsa mafunde akulu amagetsi.

Mawonekedwe

●The ankachitira zojambulazo mu imvi kapena wofiira
●High peel mphamvu
●Ubwino wa kugona
●Kumamatira kwabwino kwa etching kukana
●Kukana kwabwino kwa dzimbiri

Ntchito yeniyeni

●Phenolic
●Epoxy board
●CEM-1, CEM-3
●FR-4, FR-3
●Ichi ndiye chojambula chathu chopangidwa ndi ED copper chokhala ndi mbiri yayitali kwambiri yogwiritsidwa ntchito ngati wosanjikiza wakunja wama board olimba.

Ubwino wapamwamba
● 0 magawo pa koyilo
● Chophimbacho kuti chikhale ndi mtundu wofanana, waukhondo ndi wosanja
● Palibe maenje oonekera, mabowo apini kapena dzimbiri
● Palibe zolakwika zapamtunda monga mikwingwirima, mawanga kapena mizere
● Chophimbacho chiyenera kukhala chopanda mafuta ndipo sichikhala ndi madontho owoneka amafuta
