Boto ea fiber ea epoxy ea FR4
Kenyelletso ea sehlahisoa
FR-4 e boetse e bitsoa boto ea epoxy ea FR4, ‘me tlhophiso ea eona e pharalletse haholo. Mefuta ea mantlha ke:
G11: Sehlopha sa mollo oa lelakabe UL94V0. Sebakeng se ommeng le se metsi, ts’ebetso ea motlakase e ntse e le ntle haholo. Ke khetho e ntle bakeng sa ho kenya motlakase.
G10: Sekhahla se thibelang malakabe UL94V2, sebakeng se omileng le se metsi, ts’ebetso ea motlakase e ntse e le ntle haholo, ke khetho e ntle bakeng sa likarolo tsa motlakase
JC833: kalaka e thibelang malakabe UL94V0, letsoalo le ka hare ho 1.8-2.0, le sebelisoa haholo likarolong tsa motlakase le tsa elektroniki le lipoleiti tse sirelletsang lifofane, likoloi tsa likoloi, li-transformer, likepe tse nepahetseng tsa likepe, jj.
JC834: lelakabe retardant sehlopheng UL94V0, segokanyipalo ka hare ho 1.8-2.0, ho pharaletseng sebelisoa ka likarolo motlakase le elektroniki kwahelang, lifofane, likoloi likoloi, mapolanka kwahelang kwahelang, sebetsa ka ho nepahetseng likepe Bay, joalo-joalo
fr4 epoxy board e hlahisa lesela le bopehileng joaloka poleiti le entsoeng ka lesela la khalase ea fiber le kenngoeng ka lehoakhoa la epoxy e le sekhomaretsi, se omisitsoeng le se chesang se hatisitsoeng. E na le litšobotsi tse phahameng tsa mochini, ho monya metsi, ho boloka mollo le ho hanyetsa mocheso, le thepa e tsitsitseng ea dielectric kamora ho qoelisoa ka metsing. E loketse lihlahisoa tse hlokang tšireletso e phahameng ea elektroniki, joalo ka liboto tsa matlafatso tsa FPC, mekotla ea ho cheka PCB, likhalase tsa fiber, khalase ea filimi e hatisitsoeng ka likhalase bakeng sa li-potentiometers, le likhalase tsa linaleli tse nepahetseng (ho sila), lipoleiti tsa liteko tsa motlakase, motlakase (motlakase) thepa e kwahelang lula partitions, kwahelang tšehetsa lipoleiti, lipoleiti kwahelang lipoleiti, likarolo dilenaneo kwahelang, likere sila, elektroniki switjha kwahelang lipoleiti, joalo-joalo
Litlhaloso tsa lihlahisoa
Kenyelletso ea fr4 epoxy board The board board kaofela: 1020mm * 1220mm, 1000mm * 2000mm, 914 * 1220mm, 1440 * 1440mm, 1220mm * 2440mm (bongata bo seng ba scalar bo ka hlophisoa) Botenya: 0.1mm-350mm

D. Litšobotsi tsa sehlahisoa
1. Mebala e fapaneng: Ha e bapisoa le 3240 e mosehla, FR-4 e na le ‘mala o mosoeu, o mosehla, oa aqua le o motšo oo u ka khethang ho oona. Le bokaholimo bo bataletse ebile bo boreleli ntle le bubble, mme ponahalo e ntle.
2, mollo lintlha: UL94V0, mollo zui sehlopheng. Ho fapana le palo e akaretsang ea mollo, UL94V0 e fihletse phello ea mollo le mollo oa lelakabe. E ka iphelisa ka nako e khuts’oane kamora hore thepa e fete naheng e chesang, e felehetse polokeho ea bophelo le thepa.
3. Ho kwahela ka matla: FR-4 e na le ts’ebetso e matla haholo ea ts’ireletso ea tlhaho. Sebakeng se ommeng le se metsi, ts’ebetso ea motlakase e ntse e le ntle haholo, mme ke khetho e ntle bakeng sa ho kenya motlakase.
4. Boleng bo phahameng le bo sebetsang: FR-4 e ntse e na le maemo a matle maemong a fapaneng. Hore na e tlose 100 ℃ kapa mocheso o phahameng oa 130 ℃, e ka sebelisoa.
5. Likopo tse fapaneng: Ka lebaka la boleng bo holimo ba FR-4 le polasetiki ea eona e matla, e sebelisoa haholo likarolong tsa motlakase le tsa elektroniki, hammoho le liboto tsa ho kenya lifofane, likoloi tsa likoloi, li-transformer, likepe tse nepahetseng tsa likepe, le joalo-joalo.
