Kune akawanda marudzi emabhodhi edunhu pamusika, uye mazwi ehunyanzvi akasiyana, pakati peiyo fpc board inoshandiswa zvakanyanya, asi vanhu vazhinji havazive zvakawanda nezve fpc board, saka iyo fpc board inorevei?
1, fpc board inonziwo "flexible circuit board", imwe yePCB yakadhindwa redunhu bhodhi, imhando yekushandiswa kwezvinhu zvinodzivirira senge substrate, senge: polyimide kana polyester firimu, uyezve kuburikidza neakakosha maitiro akagadzirwa. yebhodhi redunhu rakadhindwa. Wiring density yeiyi redunhu bhodhi kazhinji yakakwira zvakati, asi huremu huchave hwakareruka, ukobvu huchave hutete, uye hune hunyoro hwekuita, pamwe nekuita kwakanaka kwekukotama.
2, fpc board uye PCB board musiyano mukuru. Iyo substrate yefpc board inowanzo PI, saka inogona kuve yakakombama, kuchinjika, nezvimwewo, nepo substrate yePCB board iri kazhinji FR4, saka haigone kukombamira uye kuchinjika. Naizvozvo, mashandisirwo uye mashandisirwo minda yefpc board uye PCB board zvakare akasiyana zvakanyanya.
3, nekuti iyo fpc board inogona kukotama uye kuchinjika, iyo fpc board inoshandiswa zvakanyanya munzvimbo inoda kudzokororwa kuchinjika kana kubatana pakati pezvikamu zvidiki. Bhodhi rePCB harina kuoma, saka rinoshandiswa zvakanyanya kune dzimwe nzvimbo uko risingade kukotamiswa uye kusimba kwakaoma.
4, fpc board ine zvakanakira saizi diki, huremu huremu, saka inogona kunyatso kudzikisa saizi yezvigadzirwa zvemagetsi idiki kwazvo, saka inoshandiswa zvakanyanya muindasitiri yenharembozha, indasitiri yemakomputa, indasitiri yeTV, indasitiri yekamera yedhijitari uye nezvimwe. diki, zvine mwero zvemagetsi zvigadzirwa indasitiri.
5, iyo fpc bhodhi haigone kungokotama zvakasununguka, asi zvakare inogona kukuvadzwa kana kupetwa pamwe chete, uye inogonawo kurongeka zvakasununguka zvinoenderana nezvinodiwa zvenzvimbo. Munzvimbo yetatu-dimensional, fpc board inogonawo kutamiswa kana kuti telescoped, kuitira kuti chinangwa chekubatanidza chigone kuwanikwa pakati petambo uye chikamu chegungano.
Chii chinonzi PCB yakaoma mafirimu?
1, ine divi rimwe chete PCB
Iyo base plate inogadzirwa nepepa phenol copper laminated board (bepa phenol sehwaro, rakaputirwa nemhangura foil) uye pepa Epoxy copper laminated board. Mazhinji acho anoshandiswa muzvigadzirwa zvemagetsi zvemumba zvakaita seredhiyo, midziyo yeAV, hita, mafiriji, muchina wekuwachisa, uye michina yekutengeserana yakaita semaprinta, muchina wekutengesa, muchina wedunhu, uye zvinhu zvemagetsi.
2, maviri-mativi PCB
Izvo zvigadziro zveGlass-Epoxy copper laminated board, GlassComposite copper laminated board, uye bepa Epoxy copper laminated board. Mazhinji acho anoshandiswa mumakomputa emunhu, zvemagetsi Musical Instruments, multi-function nhare, mota dzemagetsi michina, electronic peripherals, electronic toys, etc. Kana iri Glass benzene resin copper laminated laminates, Glass polymer copper laminated laminates inonyanya kushandiswa mumichina yekutaurirana. , michina yekutepfenyura setiraiti, uye michina yekufambisa nhare nekuda kwehunhu hwayo hwakanakisa hwepamusoro-frequency, uye chokwadi, mutengo wakakwira zvakare.
3, 3-4 zvikamu zvePCB
Iyo yekutanga zvinhu inonyanya kuve Glass-Epoxy kana benzene resin. Inonyanya kushandiswa mumakomputa emunhu, Me (medical electronics, medical electronics) machines, michini yekuyeresa, semiconductor test machines, NC (NumericControl, numberal control) machines, electronic switches, communication machines, memory circuit board, IC cards, nezvimwewo, zviripo. zvakare girazi synthetic copper laminated board seyakawanda-layer PCB zvinhu, Kunyanya tarisa pane ayo akanakisa ekugadzirisa maitiro.
4,6-8 zvikamu zvePCB
Iyo base material ichiri yakavakirwa paGLASS-epoxy kana Glass benzene resin. Inoshandiswa mumagetsi switch, semiconductor yekuyedza michina, yepakati-saizi yemakomputa emunhu, EWS (EngineeringWorkStation), NC nemimwe michina.
5, anopfuura gumi akaturikidzana ePCB
Iyo substrate inonyanya kugadzirwa neGlass benzene resin, kana GLASS-epoxy seyakawanda-layer PCB substrate zvinhu. Kushandiswa kwerudzi urwu rwePCB kunonyanya kukosha, mazhinji acho makomputa akakura, makomputa anomhanya-mhanya, michina yekutaurirana, nezvimwewo, kunyanya nekuti ine hunhu hwepamusoro-soro uye hunhu hwekushisa kwepamusoro.
6, zvimwe PCB substrate zvinhu
Zvimwe zvePCB substrate zvinhu aluminium substrate, iron substrate uye zvichingodaro. Dunhu rinoumbwa pane substrate, iyo yakawanda inoshandiswa mukutenderera (mota diki) mota. Uye zvakare, kune inochinjika PCB (FlexiblPrintCircuitBoard), iyo dunhu inoumbwa papolymer, polyester uye zvimwe zvinhu zvikuru, zvinogona kushandiswa sechinhu chimwe chete, kaviri layer, kune akawanda-layer board anogona kuva. Iri rinochinjika redunhu bhodhi rinonyanya kushandiswa munzvimbo dzinofambiswa dzemakamera, OA michina, nezvimwewo, uye kubatana pakati peiyo yakaoma PCB kana iyo inoshanda yekubatanidza musanganiswa pakati pePCB yakaoma nePCB yakapfava, sekunge nzira yekubatanidza yekubatanidza nekuda kwekukwirira. elasticity, chimiro chayo chakasiyana.
Multi-layer board uye yepakati uye yakakwirira TG ndiro
Kutanga, akawanda-layer PCB edunhu mabhodhi anowanzoshandiswa munzvimbo dzipi?
Multilayer PCB redunhu mabhodhi anowanzo shandiswa mumidziyo yekutaurirana, midziyo yekurapa, kutonga kwemaindasitiri, chengetedzo, mota dzemagetsi, yendege, komputa peripheral fields; Se "core main force" muminda iyi, nekuenderera mberi kwekuwedzera kwemabasa echigadzirwa, mitsara yakawanda uye yakaoma, zvinodiwa zvemusika zvinoenderana zvemhando yebhodhi zviri kuwedzera nekukwira, uye kudiwa kwevatengi kwepakati nepamusoro. TG redunhu mabhodhi ari kuramba achiwedzera.
Chechipiri, iyo yakasarudzika yeakawanda-layer PCB wedunhu mabhodhi
Zvakajairwa PCB board ichave nedeformation uye mamwe matambudziko pakupisa kwakanyanya, nepo mechanic uye magetsi maitiro anogonawo kuderera zvakanyanya, achidzikisa hupenyu hwebasa rechigadzirwa. Munda wekushandiswa kwe-multi-layer PCB board inowanzowanikwa mune yepamusoro-yekupedzisira tekinoroji indasitiri, iyo inoda zvakananga kuti bhodhi rive nekugadzikana kwepamusoro, kukwirira kwemakemikari kushomeka, uye inogona kumira tembiricha, hunyoro hwepamusoro uye zvichingodaro.
Naizvozvo, kugadzirwa kweakawanda-layer PCB mabhodhi anoshandisa angangoita TG150 mahwendefa, kuitira kuti ive nechokwadi chekuti bhodhi redunhu rinoderedzwa nekunze zvinhu mukuita kwekushandisa uye kuwedzera hupenyu hwebasa rechigadzirwa.
Yetatu, yakakwira TG plate mhando kugadzikana uye yakakwirira kuvimbika
Chii chinonzi TG kukosha?
TG kukosha: TG ndiyo tembiricha yepamusoro iyo iyo pepa rinoramba rakasimba, uye TG kukosha inoreva tembiricha iyo iyo amorphous polymer (inosanganisirawo amorphous chikamu checrystalline polymer) shanduko kubva kune yegirazi kuenda kune yakakwira elastic state (rabha. nyika).
Iko kukosha kweTG ndiyo tembiricha yakakosha apo iyo substrate inonyungudika kubva pakasimba kuenda kumvura yerubha.
Chiyero cheTG kukosha chakanangana nekugadzikana uye kuvimbika kwePCB zvigadzirwa, uye iyo yakakwirira kukosha kweTG yebhodhi, iyo yakasimba kugadzikana uye kuvimbika.
High TG sheet ine zvinotevera zvakanaka:
1) Kupisa kupisa kwakanyanya, izvo zvinogona kuderedza kuyerera kwePCB pads panguva ye infrared inopisa kunyunguduka, welding uye kupisa kwemafuta.
2) Kuderera kwekuwedzera kwemafuta ekuwedzera (yakaderera CTE) kunogona kuderedza kurwiswa kunokonzerwa nemamiriro ekushisa, uye kuderedza kutsemuka kwemhangura pakona yegomba kunokonzerwa nekuwedzera kwekushisa, kunyanya mumabhodhi ePCB ane masere kana kupfuura, kushanda kwepakuputirwa nemakomba. iri nani pane iyo yePCB mabhodhi ane general TG kukosha.
3) Iine yakanakisa makemikari kuramba, kuitira kuti PCB bhodhi inogona kunyikwa mukunyorova kwekurapa maitiro uye akawanda emakemikari mhinduro, kuita kwayo kuchiri kwakasimba.
