Maɓalli shrapnel
Allunan Guozi gabaɗaya suna nufin shrapnel maɓalli
Maɓallin shrapnel (wanda aka fi sani da dome na ƙarfe, dome mai karye) an yi shi da bakin ciki-baƙi (0.05mm-0.1mm kauri) da ultra-kauri (mafi wuya) bakin karfe 301 ko 304 kayan.Maɓalli shrapnel wani muhimmin sashi ne na sauyawa.
Sunan Sinanci: Button shrapnel
Har ila yau, an san shi da: Pot slices
Material: Bakin Karfe 301 ko 304
Diamita: 3mm zuwa 20mm
An fi amfani da shrapnel na maɓalli a cikin musanya na membrane, masu mu'amala da dome, allon PCB, allon FPC, kayan aikin likita da sauran samfuran.Ka'idar aiki na shrapnel maballin: Maɓallin maɓalli akan maɓallin membrane yana kan sashin gudanarwa na allon PCB (mafi yawa yana sama da yatsun zinari akan allon kewayawa).Lokacin da aka danna, tsakiyar wurin shrapnel ya kasance maɗaukaki kuma yana taɓa kewaye akan PCB., Don haka samar da madauki, halin yanzu yana wucewa, kuma duk samfurin zai iya aiki akai-akai.
Gabaɗaya, za a iya raba shrapnels na maɓalli na al'ada zuwa juzu'in juzu'in ƙarfe, shrapnel ɗin ƙarfe mai siffar giciye, shrapnel na ƙarfe mai kusurwa uku, da shrapnel ɗin ƙarfe na kwandon ƙarfe bisa ga nau'ikan su daban-daban.A diamita jeri daga 3mm zuwa 20mm, da kuma ƙarfi jeri daga 100g zuwa 600gf.Dangane da jiyya ta fuskar lantarki, ana iya raba shi zuwa: platin zinariya, plating nickel, plating na azurfa, saman haske da sauransu.Akwai nau'i biyu na electroplating mai gefe guda da na lantarki mai gefe biyu.
