Eqinile-PCB eguqukayo luhlobo olutsha lwebhodi yesekethe eprintiweyo edibanisa ukuqina kwe-PCB eqinile kunye nokuguquguquka kwe-PCB eguquguqukayo (FPC). Phakathi kwazo zonke iintlobo zeebhodi zeesekethe, i-PCB eqinile-eguqukayo inika ukuxhathisa okunamandla kwiindawo ezibuhlungu, izenza zidume phakathi kwabavelisi bolawulo lwamashishini, unyango kunye nezixhobo zomkhosi. I-WonderfulPCB iphinda inyuse ngokuthe ngcembe umlinganiselo we-PCB eqinileyo kwimveliso yayo iyonke.
Iingenelo ze-PCB eqinile-flex ziipropati zabo ezibalaseleyo kuzo zombini PCB eqinile kunye neeFPC ezibhetyebhetye. Zinokusongwa, zigobe, kwaye zigcine indawo, ngelixa zivumela ukuwelda okuntsonkothileyo kwamacandelo. Xa kuthelekiswa neentambo zemveli, zinika ubomi obude, uzinzo oluthembeke ngakumbi, kwaye aziqhelekanga ukuphuka, i-oxidation, okanye i-detachment, iphucula kakhulu ukusebenza kwemveliso. Nangona kunjalo, i-PCB eqinile-eguquguqukayo inemiqobo ethile: imveliso yabo ibandakanya iinkqubo ezininzi, kunzima ukuvelisa, zinezinga eliphantsi lesivuno, zifuna isixa esikhulu sezinto kunye nomsebenzi, okwenza ukuba kubize kunye nomjikelo wemveliso omde.
Ziziphi izicelo ze-rigid-flex PCB?
1.Sebenzisa Industrial – Oku kubandakanya izicelo kumashishini afana nemimandla yomkhosi kunye nezonyango. Uninzi lwamacandelo amashishini afuna ukuchaneka, ukhuseleko, kunye nokuqina, ukwenza iipropathi ezifunekayo ze-PCB eqinile-flex ukuthembeka okuphezulu, ukuchaneka okuphezulu, ilahleko ephantsi ye-impedance, umgangatho obalaseleyo wokuhambisa umqondiso, kunye nokuqina. Nangona kunjalo, ngenxa yobunzima benkqubo, umthamo wemveliso uncinci, kwaye ixabiso leyunithi liphezulu.
2.Mobile Phones -Usetyenziso oluqhelekileyo lwe eqinile-flex PCB kwiifowuni eziphathwayo ziquka ihenjisi yeefowuni ezisongekayo, iimodyuli zekhamera, i-keyPAD, kunye neemodyuli zeRF.
3.Electronics Consumer - Kwiimveliso zabathengi, i-DSC (i-digital still cameras) kunye ne-DV (ividiyo yedijithali) zixhobo ezimele eziqhuba ukuphuhliswa kwe-PCB eqinile. Badibanisa iibhodi ezinzima ze-PCB kunye namacandelo kwimilinganiselo emithathu, ukwandisa indawo enokusebenziseka epheleleyo ye-PCB ngelixa ugcina ukuxinana kwesekethe efanayo. Oku kuphucula umthamo wesiphaluka kunye nokunciphisa ukulinganiselwa kokudluliselwa kwesignali kunye namazinga eempazamo zendibano. Ukongezelela, ekubeni iibhodi eziqinileyo eziguquguqukayo zilula, zincinci, kwaye zibhetyebhetye, zinegalelo ekunciphiseni ubungakanani bemveliso kunye nobunzima.
4.Automotive - Kwizithuthi, i-PCB eqinile-eguquguqukayo isetyenziswe kwizicelo ezifana namaqhosha okudibanisa kwivili lokuqhuba kwi-motherboard, izikrini zokudibanisa kunye neepaneli zokulawula kwiinkqubo zevidiyo zemoto, amaqhosha okulawula kwiipaneli zocango lwemoto, iinkqubo ze-reverse imaging radar, sensors (umgangatho womoya, ubushushu, umswakama, kunye nolawulo olukhethekileyo lwegesi), iinkqubo zonxibelelwano, iinkqubo ze-satellites zokulawula, i-backseat control panel, i-backseat control system, i-backseat ye-backseat system.
Amanqaku aphambili kwiRigid-Flex PCB Manufacturing
Ukudalwa kunye nophuhliso lwe-FPC kunye ne-PCB yazala i-PCB eqinile-flex, eyenziwa ngokudibanisa. iibhodi zesekethe eziguquguqukayo kunye neebhodi zeesekethe eziqinileyo ngokusebenzisa iinkqubo ezifana ne-lamination. Inqaku eliphambili kwi-rigid-flex flex PCB yokuvelisa i-lamination process, ngakumbi kwi-junction phakathi kwamacandelo aguquguqukayo kunye aqinile. Ngelixa i-PCB ezimeleyo okanye iinkqubo ze-FPC zokuthambisa zivuthiwe, ukudibanisa ezi ntlobo zimbini kwiibhodi eziqinileyo eziguqukayo kuhlala kungumngeni kubavelisi.
- Ukusetyenziswa koomatshini be-vacuum lamination kuqinisekisa uxinzelelo oluqhubekayo kunye nobushushu bokunamathela ngokufanelekileyo kunye nokudibanisa izinto eziphathekayo.
- Izixhobo ezifanelekileyo zokugquma kufuneka zikhethwe: isigqubuthelo esithambileyo singabonisa imikhondo yesinyithi kunye neepateni kumphezulu, ngelixa izinto ezinzima kakhulu zinokubangela uxinzelelo kunye namaqamza.
Imingeni kwiRigid-Flex PCB Manufacturing
I-Rigid-flex PCB ibandakanya iinkqubo ezintsonkothileyo, kwaye ubugcisa obuthile kunye nemingeni kunzima ukuyilawula. Ukwahluka kwesakhiwo kunye nempahla phakathi kweebhodi eziguquguqukayo kunye eziqinileyo kubangela ukungafani okuphawulekayo ekuzinzeni kwabo kwe-dimensional, okwenza ukhetho lwezixhobo ezifanelekileyo lubaluleke kakhulu ukulungelelaniswa okufanelekileyo.
Kwicandelo eliguquguqukayo:
- Izinto ezithambileyo kufuneka zikhokelwe kumgca wokuvelisa usebenzisa ipleyiti yecarrier ukuze ugweme i-jamming kunye nokumoshakala.
- Ukuphathwa okuchanekileyo kweeleyile zomntu ngamnye kubaluleke kakhulu kukulungelelaniswa, ngakumbi ngenxa yobuntununtunu bemathiriyeli yepolyimide kwizisombululo ezinamandla zealkaline, ezinokubangela ukudumba.
- Umgangatho wokunyibilika unokuphuculwa ngokusebenzisa izixhobo ezifanelekileyo ze-buffer njengefilimu yepolypropylene okanye amaphepha e-PTFE ukuphucula ukudibanisa phakathi kweeleya.
Kwicandelo eliqinileyo:
- Ukuqinisekisa umkhombandlela ofanayo wenkozo yelaphu leglasi yefayibha kunye nokuphelisa uxinzelelo lobushushu ngexesha le-lamination ukunqanda ukulwa.
- Ukulawula ukwandiswa kunye nokunciphisa ngexesha le-lamination, ngakumbi kumacandelo aguquguqukayo.
- Iifestile ze-Flex zinokucutshungulwa kusetyenziswa iindlela zangaphambili zokugaya okanye emva kokugaya, kuxhomekeke kwisakhiwo sebhodi kunye nobukhulu.
Impembelelo yexabiso leMathiriyeli ekrwada Yonyuka kwiiNdleko ze-Rigid-Flex PCB
Ukusukela ngoSeptemba 2020, amaxabiso eCCL (copper clad laminate) anyuke kakhulu, eqhutywa kukunqongophala kwezinto eziluhlaza kunye nemfuno emandla esezantsi. Ukunyuka kweendleko zemathiriyeli ekrwada, ngakumbi ubhedu, ifayibha yeglasi, kunye nentlaka, kunyuse amaxabiso eCCL ukuya kuthi ga kwi-100%. Nangona kunjalo, oku kunyuka kwexabiso kuye kwaba nempembelelo encinci kwiindleko ze-PCB eziguquguqukayo, kuba iindleko zempahla zithatha inxalenye encinci yeendleko ezipheleleyo xa kuthelekiswa ne-PCB eqhelekileyo.
Amanqaku okulawula umgangatho kwiModyuli yeKhamera eRigid-Flex PCB Manufacturing
Imodyuli yekhamera eqinile-i-PCB inzima kakhulu ukuyenza ngenxa yesithuba esincinci (i-2-3 mil) phakathi kwe-COB (i-chip-on-board) i-PAD kunye nesidingo sonyango oluphezulu olufana ne-ENEPIG (i-Electroless Nickel Electroless Palladium Immersion Gold), enokukhokelela kwi-etching ecaleni. Ukujongana noku, imingeni emibini kufuneka isonjululwe:
- I-Fine Line Etching - Ukusingatha ubungakanani obuncinci be-COB PAD, i-LDI (i-laser i-imaging ngqo) kufuneka isetyenziswe oomatshini be-exposure, njengoko banikezela ngesisombululo esiphezulu kunoomatshini bendabuko. Oku kunceda ukuphepha ukungahambi kakuhle ngexesha lokuvezwa.
- Solder Mask Side-Etch Control – I-inki ye-mask ye-finer ye-solder kufuneka isetyenziswe ukunciphisa ii-pores kwi-inki, ezinokuthi zikhokelele kumazinga aphezulu e-side-plating kunye neesekethe ezimfutshane ngexesha lonyango lomphezulu.
Ukuqukumbela, rigid-flex PCB prototyping kunye nokuvelisa kubandakanya imingeni ekhethekileyo ngenxa yesakhiwo sabo sezinto eziphathekayo kunye nezicelo, ezifuna ukulungiswa kwinyathelo ngalinye lokuvelisa ukunyusa iinkqubo kunye neeparitha.
