Muaj ntau ntau hom Circuit Court boards nyob rau hauv kev ua lag luam, thiab cov kev ua hauj lwm cov nqe lus yog txawv, ntawm cov uas fpc board yog dav siv, tab sis muaj coob tus neeg tsis paub ntau npaum li cas ntawm fpc board, yog li ntawd lub fpc board txhais li cas?
1, fpc pawg thawj coj saib kuj tseem hu ua "lub rooj tsav xwm hloov tau yooj yim", yog ib qho ntawm PCB luam tawm Circuit Board, yog ib hom kev siv cov khoom siv insulating ua substrate, xws li: polyimide lossis polyester zaj duab xis, thiab tom qab ntawd los ntawm cov txheej txheem tshwj xeeb ua. ntawm printed circuit board. Qhov kev sib txuas ntawm lub rooj tsav xwm no feem ntau yog qhov siab, tab sis qhov hnyav yuav yog lub teeb, lub thickness yuav nyias nyias, thiab muaj kev ua haujlwm zoo, nrog rau kev ua haujlwm zoo bending.
2, fpc board thiab PCB board yog qhov sib txawv loj. Lub substrate ntawm fpc pawg thawj coj saib feem ntau yog PI, yog li nws tuaj yeem khoov, flexed, thiab lwm yam, thaum lub substrate ntawm PCB pawg thawj coj saib feem ntau yog FR4, yog li nws tsis tuaj yeem khoov thiab flexed. Yog li ntawd, kev siv thiab daim ntawv thov teb ntawm fpc board thiab PCB board kuj txawv heev.
3, vim tias fpc board tuaj yeem khoov thiab flexed, fpc board yog dav siv nyob rau hauv txoj hauj lwm uas yuav tsum tau rov flexed los yog kev sib txuas ntawm cov khoom me me. Lub rooj tsavxwm PCB yog qhov nruj, yog li nws tau siv dav hauv qee qhov chaw uas nws tsis tas yuav khoov thiab lub zog kuj nyuaj.
4, fpc board muaj qhov zoo ntawm qhov me me, lub teeb yuag, yog li nws tuaj yeem txo qhov loj ntawm cov khoom siv hluav taws xob me me, yog li nws tau siv dav hauv kev lag luam xov tooj ntawm tes, khoos phis tawj kev lag luam, TV kev lag luam, digital koob yees duab kev lag luam thiab lwm yam. kuj me me, kuj sophisticated electronic khoom lag luam.
5, lub rooj tsavxwm fpc tuaj yeem tsis tsuas yog tuaj yeem khoov tau yooj yim, tab sis kuj tuaj yeem raug mob lossis quav ua ke, thiab tseem tuaj yeem tsim kev ywj pheej raws li qhov xav tau ntawm qhov chaw layout. Nyob rau hauv qhov chaw peb sab, fpc board kuj tuaj yeem txav tau los yog tsom iav, kom lub hom phiaj ntawm kev sib koom ua ke tuaj yeem ua tiav ntawm cov hlau thiab cov khoom sib dhos.
PCB dry films yog dab tsi?
1, ib sab PCB
Lub hauv paus phaj yog ua los ntawm daim ntawv phenol tooj liab laminated board (paper phenol li lub hauv paus, coated nrog tooj liab ntawv ci) thiab ntawv Epoxy tooj liab laminated board. Lawv feem ntau yog siv rau hauv cov khoom siv hluav taws xob hauv tsev xws li xov tooj cua, AV cov khoom siv, cov cua sov, cov tub yees, cov tshuab ntxhua khaub ncaws, thiab cov tshuab ua lag luam xws li tshuab luam ntawv, vending machine, circuit machines, thiab cov khoom siv hluav taws xob.
2, ob sab PCB
Cov ntaub ntawv hauv paus yog iav-Epoxy tooj liab laminated board, GlassComposite tooj liab laminated board, thiab ntawv Epoxy tooj liab laminated board. Lawv feem ntau yog siv rau hauv cov computers, electronics Musical Instruments, multi-function telephones, automotive electronic machines, electronic peripherals, electronic toys, etc. Raws li rau iav benzene resin tooj liab laminated laminates, iav polymer copper laminated laminates feem ntau yog siv rau hauv kev sib txuas lus tshuab. , satellite broadcasting machines, thiab mobile kev sib txuas lus tshuab vim lawv zoo heev high-frequency yam ntxwv, thiab tau kawg, tus nqi kuj yog siab.
3, 3-4 txheej ntawm PCB
Cov khoom siv hauv paus yog iav-Epoxy lossis benzene resin. Feem ntau siv rau hauv cov computers, Kuv (kev kho mob hluav taws xob, kev kho mob hluav taws xob) cov cav tov, ntsuas tshuab, semiconductor testing machines, NC (NumericControl, numerical control) machines, electronic switches, communication machines, memory circuit boards, IC cards, etc., muaj kuj iav hluavtaws tooj liab laminated board ua ntau txheej PCB cov ntaub ntawv, Feem ntau tsom rau nws cov yam ntxwv zoo heev.
4,6-8 txheej ntawm PCB
Cov khoom siv hauv paus tseem yog GLASS-epoxy lossis iav benzene resin. Siv nyob rau hauv hluav taws xob keyboards, semiconductor kuaj tshuab, nruab nrab-qhov loj me ntawm tus kheej lub computer, EWS (EngineeringWorkStation), NC thiab lwm yam tshuab.
5, ntau tshaj 10 txheej ntawm PCB
Lub substrate feem ntau yog ua los ntawm iav benzene resin, los yog GLASS-epoxy ua ntau txheej PCB substrate khoom. Daim ntawv thov ntawm PCB hom no tshwj xeeb tshaj yog, feem ntau ntawm lawv yog cov khoos phis tawj loj, cov khoos phis tawj siab ceev, tshuab sib txuas lus, thiab lwm yam, feem ntau vim tias nws muaj cov yam ntxwv siab zaus thiab cov yam ntxwv kub zoo heev.
6, lwm yam khoom siv PCB substrate
Lwm cov ntaub ntawv PCB substrate yog aluminium substrate, hlau substrate thiab lwm yam. Lub Circuit Court yog tsim nyob rau hauv lub substrate, feem ntau yog siv nyob rau hauv lub turnaround (me me lub cev muaj zog) tsheb. Tsis tas li ntawd, muaj cov PCB hloov tau yooj yim (FlexiblPrintCircuitBoard), lub Circuit Court yog tsim los ntawm cov polymer, polyester thiab lwm yam ntaub ntawv tseem ceeb, yuav siv tau raws li ib txheej, ob txheej, rau ntau txheej board tuaj yeem ua tau. Lub rooj tsavxwm hloov tau yooj yim no feem ntau yog siv rau hauv qhov chaw txav tau ntawm cov koob yees duab, OA cov cav tov, thiab lwm yam, thiab kev sib txuas ntawm cov PCB nyuaj los yog kev sib txuas zoo ntawm cov tawv PCB thiab cov mos PCB, xws li kev sib txuas ntawm kev sib txuas vim siab. elasticity, nws cov duab yog diversified.
Multi-layer board thiab nruab nrab thiab siab TG phaj
Ua ntej, ntau txheej PCB Circuit Court boards feem ntau siv nyob rau hauv cov cheeb tsam twg?
Multilayer PCB circuit boards feem ntau yog siv rau hauv cov khoom siv sib txuas lus, khoom siv kho mob, kev tswj hwm kev lag luam, kev ruaj ntseg, automotive electronics, aviation, computer peripheral fields; Raws li "core lub zog tseem ceeb" nyob rau hauv cov teb no, nrog kev ua lag luam dense, ntau dua kev lag luam yuav tsum tau nce siab thiab siab dua, thiab cov qhua tuaj noj mov xav tau rau nruab nrab thiab siab TG circuit boards tas li nce.
Qhov thib ob, qhov tshwj xeeb ntawm ntau txheej PCB Circuit Court boards
Ordinary PCB pawg thawj coj saib yuav muaj deformation thiab lwm yam teeb meem ntawm qhov kub thiab txias, thaum lub tshuab thiab hluav taws xob cov yam ntxwv kuj tseem yuav poob qis, txo cov kev pab cuam lub neej ntawm cov khoom. Daim ntawv thov ntawm ntau txheej PCB pawg thawj coj saib yog feem ntau nyob rau hauv high-end technology kev lag luam, uas ncaj qha hais tias lub rooj tsavxwm muaj siab stability, siab chemical resistance, thiab muaj peev xwm tiv taus kub, high humidity thiab thiaj li nyob.
Yog li ntawd, ntau txheej PCB boards siv tsawg kawg yog TG150 daim hlau, thiaj li yuav xyuas kom meej tias lub Circuit Court board raug txo los ntawm lwm yam nyob rau hauv tus txheej txheem ntawm daim ntawv thov thiab ncua kev pab cuam lub neej ntawm cov khoom.
Thib peb, siab TG phaj hom kev ruaj ntseg thiab kev ntseeg siab
Tus nqi TG yog dab tsi?
TG tus nqi: TG yog qhov kub siab tshaj plaws uas cov ntawv tseem nruj, thiab TG tus nqi yog hais txog qhov kub ntawm qhov amorphous polymer (tseem suav nrog amorphous ib feem ntawm crystalline polymer) hloov los ntawm lub xeev iav mus rau lub xeev siab elastic (rubber) xeev).
Tus nqi TG yog qhov ntsuas kub tseem ceeb uas lub substrate melts los ntawm cov khoom mus rau cov kua roj hmab.
Cov theem ntawm TG tus nqi yog ncaj qha ntsig txog kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom PCB, thiab qhov siab dua TG tus nqi ntawm lub rooj tsavxwm, lub zog ruaj khov thiab kev ntseeg siab.
High TG daim ntawv muaj qhov zoo hauv qab no:
1) Kev kub siab ua haujlwm, uas tuaj yeem txo qhov ntab ntawm PCB pads thaum lub sij hawm infrared kub yaj, vuam thiab thermal shock.
2) Tsawg thermal expansion coefficient (qis CTE) tuaj yeem txo qhov kev sib tsoo los ntawm qhov kub thiab txias, thiab txo cov tooj liab tawg ntawm lub ces kaum ntawm lub qhov los ntawm thermal expansion, tshwj xeeb tshaj yog nyob rau hauv PCB boards nrog yim los yog ntau txheej txheej, kev ua tau zoo ntawm plated los ntawm lub qhov. yog zoo dua li ntawm PCB boards nrog TG qhov tseem ceeb.
3) Muaj cov tshuaj tiv thaiv zoo heev, yog li PCB pawg thawj coj tuaj yeem tsau rau hauv cov txheej txheem kev kho ntub dej thiab ntau cov tshuaj daws teeb meem, nws qhov kev ua tau zoo tseem tsis zoo.
