Kayayyaki da hanyoyin zaɓin sassauƙan kayan keɓaɓɓiyar hukumar kewaya

(1) FPC canzawa

Ana amfani da polyimide azaman kayan katako mai sassauƙa, wanda shine babban zafin zafin jiki da kayan polymer mai ƙarfi. Yana da kayan polymer wanda DuPont ya ƙirƙira. Polyimide da DuPont ya samar ana kiranta Kapton. Bugu da kari, zaku iya siyan wasu polyimides da aka samar a Japan, waɗanda suke da arha fiye da DuPont.

Zai iya tsayayya da zafin jiki na 400 ℃ na daƙiƙa 10 kuma yana da ƙarfin ƙarfi na 15000-30000 psi.

ashirin da biyar μ M kauri FPC substrate shine mafi arha kuma mafi yawan amfani. Idan katako mai sassauƙa yana buƙatar yin wahala, yakamata a zaɓi 50 material M tushe. A akasin wannan, idan hukumar da’irar mai sassauƙa tana buƙatar taushi, zaɓi kayan tushe na 13 μ M.

(2) M m ga FPC substrate

An raba shi zuwa epoxy resin da polyethylene, duka biyun sune adhesives na thermosetting. Ƙarfin polyethylene yana da ƙarancin inganci. Idan kuna son allon kewaye ya zama mai taushi, zaɓi polyethylene.

A kauri da substrate da m m a kan shi, da wuya da kewaye hukumar. Idan hukumar da’irar tana da yanki mai lanƙwasa, yakamata a zaɓi madaidaiciyar madaidaiciyar madaidaiciya da madaidaicin madaidaiciya don rage damuwa a farfajiyar takardar jan ƙarfe, ta yadda damar ƙananan fasa a cikin takardar jan ƙarfe kaɗan ne. Tabbas, don irin waɗannan yankuna, yakamata a zaɓi allon alƙaluma ɗaya gwargwadon iko.

(3) FPC jan ƙarfe

An raba shi zuwa kalanda da aka ƙera da jan ƙarfe na lantarki. Ƙarfe da aka ƙera yana da ƙarfi da juriya mai lanƙwasa, amma farashin yana da tsada. Karfe na lantarki yana da arha sosai, amma yana da ƙarfi kuma yana da sauƙin karyewa. Yawanci ana amfani da shi a lokuta da ban lanƙwasa.

Za a zaɓi kaurin murfin jan ƙarfe gwargwadon ƙaramin faɗin da mafi ƙarancin tazara. Ƙarfin murfin jan ƙarfe, ƙaramin ƙaramin nisa da tazarar da za a iya samu.

Lokacin zaɓar jan ƙarfe da aka ƙera, kula da jagorar kalanda na takardar jan ƙarfe. Hanyar calendering na jan karfe na jan ƙarfe za ta yi daidai da babban lanƙwasa shugaban hukumar kewaye.

(4) Fim ɗin kariya da m nashi

Hakanan, fim mai kariya na 25 μ M zai sa katako mai sassauƙa ya yi wuya, amma farashin ya yi rahusa. Don allon kewaye tare da babban lanƙwasa, zai fi kyau zaɓi fim mai kariya na 13 μ M.

Hakanan an raba m m zuwa epoxy resin da polyethylene. Kwamitin kewaye da ke amfani da resin epoxy yana da wahala. Bayan matsi mai zafi, za a fitar da wasu madaidaicin m daga gefen fim ɗin kariya. Idan girman kushin ya fi girma fiye da girman buɗe fim ɗin mai kariya, ƙyallen da aka cire zai rage girman kushin kuma ya haifar da gefuna marasa daidaituwa. A wannan lokacin, yakamata a zaɓi 13 gwargwadon yadda zai yiwu μ M kauri mai haske.

(5) Rufin kushin

Don allon kewaye tare da babban lanƙwasawa da wani ɓangaren kushin da aka fallasa, za a karɓi baƙin ƙarfe na baƙin ƙarfe na baƙin ƙarfe na lantarki + kuma layin nickel zai zama na bakin ciki sosai: 0.5-2 μ m. Layer gwal na sinadarai 0.05-0.1 μ m。
