Menene shafi na jan karfe?

Abin da ake kira zubewar tagulla shine a yi amfani da sararin da ba a yi amfani da shi a kan PCB a matsayin abin nuni sannan a cika shi da tagulla mai kauri.Wadannan wuraren tagulla kuma ana kiran su da cikon tagulla.

Muhimmancin suturar jan ƙarfe shine don rage rashin ƙarfi na waya ta ƙasa da kuma inganta ƙarfin tsangwama;rage raguwar wutar lantarki da inganta ingantaccen wutar lantarki;idan an haɗa shi da waya ta ƙasa, kuma yana iya rage yankin madauki.

Har ila yau, don yin PCB kamar yadda ba ta lalace ba kamar yadda zai yiwu a lokacin sayar da kayan aiki, yawancin masana'antun PCB kuma za su buƙaci masu zanen PCB su cika buɗaɗɗen wurin PCB da tagulla ko grid-kamar ƙasa wayoyi.Idan ba a kula da jan karfe da kyau ba, zai kasance Idan riba ba ta cancanci asara ba, shin rufin jan ƙarfe ya “fi fa’ida fiye da rashin amfani” ko kuma “rashin lahani fiye da fa’ida”?

Kowane mutum ya san cewa a cikin yanayin mita mai girma, ƙarfin da aka rarraba na wayoyi a kan allon da aka buga zai yi aiki.Lokacin da tsayin ya fi 1/20 na madaidaicin madaidaicin zangon amo, tasirin eriya zai faru, kuma za a fitar da karar ta hanyar wayoyi.Idan akwai ƙarancin jan ƙarfe a cikin PCB, zuba tagulla ya zama kayan aiki don yada amo.

Sabili da haka, a cikin da'ira mai girma, kada kuyi tunanin cewa an haɗa wayar ƙasa zuwa ƙasa a wani wuri.Jirgin ƙasa na laminate shine "ƙasa mai kyau".Idan an kula da murfin tagulla da kyau, murfin tagulla ba wai kawai yana haɓaka halin yanzu ba, har ma yana taka rawar dual na tsoma baki.

Biyu nau'i na jan karfe shafi
Gabaɗaya akwai hanyoyi guda biyu na asali na zub da tagulla, wato babban yanki na jan karfe da grid jan.Sau da yawa ana tambayar ko babban yanki na jan ƙarfe ya fi kyau ko grid tagulla zuba ya fi kyau.Ba shi da kyau a yi gabaɗaya.

Me yasa?Babban yanki na jan karfe yana da ayyuka biyu na haɓaka halin yanzu da garkuwa.Koyaya, idan an yi amfani da murfin tagulla mai girman yanki don siyar da igiyar ruwa, allon yana iya ɗagawa har ma da blisters.Sabili da haka, don rufin jan karfe mai girma, yawanci ana buɗe ramuka da yawa don sauƙaƙa kumburin kullin tagulla.Kamar yadda aka nuna a kasa:

Ana amfani da grid ɗin da aka yi da tagulla don yin garkuwa, kuma an rage tasirin ƙara yawan yanzu.Daga hangen nesa na zafi mai zafi, grid yana da kyau (yana rage yanayin dumama na jan karfe) kuma yana taka rawar kariya ta lantarki zuwa wani matsayi.Musamman don kewayawa kamar taɓawa, kamar yadda aka nuna a cikin hoton da ke ƙasa:

Ya kamata a nuna cewa grid ɗin yana kunshe da alamu a cikin kwatance.Mun san cewa don kewayawa, nisa na alamar yana da daidai "tsawon wutar lantarki" don mitar aiki na allon kewayawa (ainihin girman yana raba ta hanyar mitar dijital daidai da mitar aiki yana samuwa, duba littattafai masu alaƙa don cikakkun bayanai. ).

Lokacin da mitar aiki ba ta da girma sosai, watakila rawar da layin grid ba a bayyane yake ba.Da zarar tsawon wutar lantarki ya yi daidai da mitar aiki, yana da muni sosai.Za ku ga cewa PCB ba ya aiki kwata-kwata, kuma tsarin tsangwama yana aiki a ko'ina.sigina na.

Shawarar ita ce zaɓi bisa ga yanayin aiki na allon da'ira da aka ƙera, kar a riƙe abu ɗaya.Sabili da haka, da'irar maɗaukaki mai girma yana da babban buƙatu don grid masu amfani da yawa don hana tsangwama, kuma ƙananan ƙananan mita yana da babban da'irar halin yanzu da sauran cikakken tagulla da aka saba amfani da su.
