Izinto ze-FR-Grade kwi-PCB Manufacturing

Imvelaphi kunye nentsingiselo yamaBanga e-FR

I-FR imele "I-Flame Retardant," ipropati ebalulekileyo kwizinto ze-PCB. Inkqubo yokubala (1 ukuya ku-5) ibonisa ukubunjwa okuhlukeneyo kunye neempawu zezi zixhobo ezinqanda ilangatye. Ibakala ngalinye libonelela ngeepropati ezizodwa ezenza ukuba zilungele izicelo ezithile kwishishini le-elektroniki.

Ukubaluleka kokuBuyiselwa komlilo kwiiPCBs

Ukubuyiswa komlilo luphawu lokhuseleko olubalulekileyo kwiiPCB. Inceda ukuthintela ukusasazeka komlilo kwizixhobo zombane, ukunciphisa umngcipheko weengozi kunye nomonakalo wepropathi. Amabakala ahlukeneyo e-FR anikezela ngamanqanaba ahlukeneyo okumelana nomlilo, okuvumela abavelisi ukuba bakhethe ezona zinto zifanelekileyo kwiimfuno zabo ezithile.

Isishwankathelo se-FR1, FR2, FR3, FR4, kunye neFR5

Nangona i-FR4 Sheet iyeyona nto isetyenziswa kakhulu, uhlobo ngalunye lwe-FR lunendawo yalo kwimveliso ye-PCB. I-FR1 kunye ne-FR2 zizinto ezisekelwe ephepheni, i-FR3 yindibaniselwano yephepha kunye ne-epoxy, i-FR4 yi-epoxy laminate eqiniswe ngeglasi, kwaye i-FR5 yinguqulelo ye-FR4 ekwaziyo ukumelana nobushushu obuphezulu. Ukuqonda la mahluko kubalulekile ekukhetheni izinto ezifanelekileyo zesicelo esithile.

Uthelekiso oluneenkcukacha lwe-FR4 kunye ne-FR1, FR2, FR3, kunye ne-FR5

FR4 vs. FR1: Ukuqulunqwa kunye nokusebenza

Iphepha le-FR4 lenziwe ngelaphu le-fiberglass elukiweyo eline-epoxy resin binder, ngelixa i-FR1 isebenzisa iphepha elifakwe i-phenolic resin. Iphepha le-FR4 linika amandla aphezulu oomatshini, ubushushu obungcono bombane, kunye nokumelana nobushushu obuphezulu xa kuthelekiswa ne-FR1. Nangona kunjalo, i-FR1 ingabizi kakhulu kwaye ifanelekile kwizicelo ezilula nezingabizi kakhulu.

FR4 vs. FR2: Ukuqina kunye nokuqwalaselwa kweendleko

I-FR2, njenge-FR1, yinto esekwe ephepheni kodwa isebenzisa inkqubo eyahlukileyo ye-resin. Nangona i-FR2 ihlala ixesha elide kune-FR1, isasilela kwi-FR4 ngokubhekiselele kumandla kunye nokumelana nobushushu. I-FR2 idla ngokusetyenziswa kwii-elektroniki zabathengi apho ixabiso liyinkxalabo ephambili, ngelixa iphepha le-FR4 likhethwayo kwiizicelo ezifuna ukuthembeka okuphezulu.

FR4 vs. FR3: Inketho yeHybrid

I-FR3 idibanisa i-gap phakathi kwezinto ezisekelwe ephepheni kunye neglasi. Idibanisa iphepha kunye ne-epoxy resin, i-FR1 ephezulu kunye ne-FR2, kodwa iwa phantsi kwe-FR4 sheet. I-FR3 ixhaphake kakhulu, nangona inokuba yindleko esebenzayo kwizicelo ezifuna ukuqina ngakumbi kunezixhobo ezisekelwe ephepheni kodwa azifuni uluhlu olupheleleyo lwephepha le-FR4.

FR4 vs. FR5: Izicelo zobushushu obuphezulu

Uthelekiso lokumelana nobushushu

I-FR5 luhlobo lobushushu obuphezulu lwe-FR4. Ngelixa i-FR4 iqhelekile ukuba nobushushu beglasi (Tg) obujikeleze i-130-140 ° C, i-FR5 inokumelana namaqondo obushushu ukuya kuthi ga kwi-170 ° C okanye ngaphezulu. Oku kwenza i-FR5 ilungele izicelo ezibandakanya amaqondo obushushu agqithisileyo okanye ukukhwela ibhayisekile rhoqo nge-thermal.

IiPropati zoomatshini kunye nokuzinza

Zombini i-FR4 kunye ne-FR5 zibonelela ngozinzo olugqwesileyo lomatshini kunye neempawu zokugquma umbane. Nangona kunjalo, i-FR5's ephuculweyo yokumelana nobushushu inika umda ekugcineni ezi zakhiwo phantsi kweemeko zobushushu obuphezulu. Oku kwenza ukuba i-FR5 ixabiseke ngokukodwa kwiimoto, kwi-aerospace, kunye nezicelo zemizi-mveliso apho ukuthembeka phantsi kweemeko ezinzima kubaluleke kakhulu.

Uhlalutyo lweNdleko-yeNzuzo: FR4 vs. FR5

Ngelixa i-FR5 iqhuba ngcono kwiimeko zobushushu obuphezulu, ixabisa ngaphezulu kwephepha le-FR4. Abavelisi kufuneka balinganise iinzuzo zokuxhathisa ubushushu obuphezulu ngokuchasene neendleko ezongeziweyo. Kwizicelo ezininzi, iFR4 ibetha umdibaniso ofanelekileyo wokusebenza kunye nokusebenza kakuhle.
