Impembelelo zobukhulu kunye nokuchazwa kwexabiso le-Fr4

Kumzi-mveliso wokuhambisa i-elektroniki, izixhobo ze-Fr4 ziyathandwa ngenxa yeepropathi zabo ezintle, iipropathi zoomatshini, kunye nokuxhathisa ubushushu. Iphepha le-FR4, indlela ebalulekileyo yale nto, ixabisekile ngokwenani lezinto, ezona zibonakalayo zibukhulu belishiti. Kweli nqaku, siza kuphonononga ngokweenkcukacha ubudlelwane phakathi kwe-FR4 Ixabiso kunye nobungakanani kunye neenkcazo zobungakanani, kwaye olu luhlu lwamaxabiso luchaphazele njani intengiso.

Okokuqala, kufuneka siqonde iimpawu ezisisiseko ze-FR4 iphepha le-FR4.FR4, eyaziwa ngokuba yi-fiber fible ye-Epoxy Relin iphepha le-EPOXY. Ngenxa yeepropathi zayo ezilungileyo zombane kunye namandla omatshini, iphepha le-Fr4 lihlala isikhundla esibalulekileyo kumzi-mveliso we-elektroniki. Nangona kunjalo, iimeko ezahlukileyo zesicelo zineemfuno ezahlukeneyo zobungqongqo kunye neenkcazo zephepha le-FR4, elichaphazela ngqo ixabiso layo.

Kwimakethi ye-FR4 ye-FR4, ixabiso lidla ngokwahlulahlulwe ngokobunzima kunye nobungakanani bephepha. Ngokubanzi, iphepha le-Fr4 linoluhlu olubanzi lobukhulu, ukusuka kwi-0.2mm kwiimilimitha ezininzi. Inkcazo yobukhulu, kwelinye icala, ihlelwe ngokweemfuno zomthengi, isuka kwiisenti ezimbalwa ukuya kwiimitha ezininzi. Ngokwanda kobunzima kunye neenkcazo, ixabiso lephepha leFR4 likwabonisa indlela ephezulu.

Ngokukodwa, xa ubukhulu bephepha le-Fr4 buncitshisiwe, iindleko zayo zemveliso ziphantsi kuba izinto ezingafunekiyo zichithwe kwaye zisebenza akukho nzima. Ngenxa yoko, ixabiso le-string fr4 iphepha le-Fr4 liqhelekileyo. Nangona kunjalo, njengoko ubunzima buyenyuka, ukusetyenziswa kwezinto ezingafunekiyo kunye nobunzima bokunyuka kwakhona, kukhokelela kwiindleko eziphezulu kunye namaxabiso aphezulu. Ukongeza, i-Fr4 i-Fr4 yamashiti obunzima obahlukeneyo yahlukile kwiipropathi zombane kunye namandla omatshini, ochaphazela ixabiso labo.

Ukongeza kubunzima, ubungakanani kunye nokucaciswa kwephepha le-Fr4 ikwayinto ebalulekileyo echaphazela ixabiso. Amashiti amancinci amancinci afanelekileyo kwinkqubo yokuhambisa kunye nezothutho, ke iindleko ziphantsi kwaye ixabiso lifikeleleke ngakumbi. Nangona kunjalo, kwi-SHE4 ye-FR4 enkulu, ubunzima bayo bokulungisa kunye neendleko zothutho ziya kunyuka kakhulu, zikhokelela kumaxabiso aphezulu. Ukongeza, iphepha elikhulu le-FR4 likwafuna indawo ngakumbi kunye nezixhobo ngexesha lemveliso kunye nokugcinwa, okwandisa iindleko zayo.

Ukudibanisa ezi zinto, ixabiso lephepha leFr4 lisiqhelo kwi-US $ 2.5-5.5 / kg. Olu luhlu lwamaxabiso lugubungela uluhlu olubanzi lweenkcazo ezivela kwi-Triener, amaxwebhu amancinci ukuya kumhlaba omkhulu, amaphepha amakhulu. Ewe kunjalo, ixabiso elithile kufuneka lithathelwe ingqalelo ngokwemfuno yentengiso, amaxabiso aphezulu emveliso kunye neendleko zemveliso.

Ngamafutshane, ixabiso lephepha leFr4 lichatshazelwe zizinto ezahlukeneyo, apho ubukhulu beempawu kunye nobukhulu beempawu zezona zinto zibalulekileyo zimbini. Amashishini okufana elenzelwe imveliso, ekukhetheni i-FR4 Sheet kufuneka asekwe kwiimfuno zabo kunye nohlahlo-lwabiwo mali lokuqwalaselwa, ukuze ukhethe ezona mveliso zilungele iimveliso zabo.
