Zvakanakira zveFlexible PCB uye Rigid-Flex PCB

Zvinoenderana neiyo IPC 6013 yakajairwa, mabhodhi anochinjika akaiswa muchikamu chimwe chete, mativi maviri-mativi, akawanda, uye rigid-flex mabhodhi.

Iyo yekugadzira maitiro eakaomesesa-flex mabhodhi anosanganisira kugadzirira zvinhu, kuumba, etching, kudhirowa, plating, inochinjika bhodhi kucheka, uye yemagetsi kuyedzwa.

Iyo yekugadzira maitiro eakaomesesa-flex mabhodhi isarudzo yakanaka yekuvaka maseketi mumaindasitiri ekurapa, aerospace, echiuto, uye ekufonera.

Nekuda kwezvakanaka zvadzo zvakaita sekureruka, kuwanda kwemagetsi, uye miniaturization, kudiwa kwemaPCB akadaro kuri kuwedzera. MaPCB anochinjika anewo dhizaini yepamusoro yemakanika uye mashandiro akanaka emagetsi nekupisa. Kufarirwa kwemaPCB anochinjika kwakatungamira kugadzirwa kwezvimwe zvigadzirwa zvine chekuita nazvo, zvakaita seHDI flexible PCBs, embedded flexible PCBs, uye rigid-flex PCBs.

Pakati pezvigadzirwa izvi zvinobva kune izvi, maPCB anochinjika anowanzo shandiswa mumaindasitiri emotokari, ekurapa, ehondo, uye endege. Kugadzirwa kwemabhodhi anochinjika kunotora nguva yakareba, kunosanganisira matanho akadai sekugadzirira zvinhu, kutema, kuboora, uye kuputira, zvichiteverwa nekugadzirwa kwechigadzirwa chekupedzisira. Gwaro iri richaongorora maPCB anochinjika uye kunzwisisa maitiro ekugadzira anochinjika.

Flexible PCBs Zvakanakira

A redunhu bhodhi rakagadzirwa flexible base zvinhu inonzi flexible PCB. Flexible PCBs (kana flex boards) anochinjika uye anochinjika, anokwanisa kuumbwa kuti asangane nezvinodiwa zveakasiyana maapplication. Kuenzaniswa nemabhodhi akaomesesa echinyakare, flex board ine zvakawanda zvakanaka, kusanganisira:

• Diki size, lightweight
• onda
• Miniaturization yematunhu, high assembly density
• Zvikanganiso zvewaya zvishoma
• Flexibility, yakakodzera pakuvaka mabhendable circuits
• Hapana kudiwa kwema mechanical connectors
• Inopindirana ne3D zvinongedzo
• Yakakwira dhigirii yemagetsi uye yemagetsi dhizaini rusununguko
• Kutendeseka kwechiratidzo chepamusoro uye kuvimbika kwedunhu
• Yakanaka impedance control
• Kuwanda kwekushisa kwekushanda
• Strong shock resistance
• Inokodzera nharaunda dzakaoma

Zvisinei nekuva nemabhenefiti aya, maPCB anochinjika ane mutengo wepamusoro kana uchienzaniswa neakaomarara kana akaomesesa-flex board. Rigid-flex mabhodhi anosanganisa zvakanakira akaomesesa uye anochinjika maPCB, achivaita bhobho pakugadzira dunhu. Izvo zvinotevera zvirimo zvichaunza rigid-flex mabhodhi uye yakaomesesa-flex maitiro ekugadzira.

Rigid-flex boards anowanzo shandiswa mumaindasitiri emotokari, ekurapa, echiuto, uye aerospace.

Chii chinonzi Rigid-Flexible Boards

Zvinoenderana neiyo IPC 6013 yakajairwa, mabhodhi anochinjika akaiswa mumhando dzakasiyana, kusanganisira imwe-sided, kaviri-sided, multilayer, uye rigid-flex mabhodhi. Type 4 pasi pe IPC 6013 inotaura mapuranga akaomarara, ayo anosanganisa zvakanakira mabhodhi anochinjika uye akaomarara. Anogona kutsanangurwa semabhodhi e hybrid kana rigid-flex board. Rigid-flex mapuranga akakamurwa kuita mapoka maviri:

1. Flexible Mounting Type - Iyi mhando inogona kungokotama kamwe chete panguva yekuisa kana kugadzirisa.
2. Dynamic Flexible Type - Mhando iyi inogona kukotama kakawanda panguva yekushandiswa.

Rigid-flex boards akakodzera kune zvikumbiro zvinoda hukuru hudiki, kureva, kudiwa kwekubatanidza zvimwe zvikamu munzvimbo diki. Yakagadzirwa mu 3D nzvimbo, yakaoma-flex mabhodhi ane yakakwirira nzvimbo kunyatsoshanda; ivo vanogona kuve vakakotama zvine simba kana kupetwa, kufambisa kuumbwa kwechimiro chinodiwa mukupedzisira chigadzirwa kurongedza; hazvidi kubatanidzwa kwakawanda, zvinoda kugadziriswa zvishoma, uye zvinozivikanwa zvakanyanya nekuda kwekuvimbika kwavo; rigid-flex boards anonyanya kushandiswa mumaindasitiri ekurapa, kufonera, uye aerospace.

Rigid-flex Manufacturing Process

Isati yaoma-inoshanduka yekugadzira maitiro atanga, iyo PCB dhizaini dhizaini inofanirwa kuitwa. Kana dhizaini yatemwa, iyo yakaoma-flex yekugadzira maitiro inogona kutanga.

Iyo yakaoma-flex yekugadzira maitiro inosanganisa maitiro ekugadzira eakaomarara uye anochinjika mabhodhi. Rigid-flex mapuranga akaturikidzana akaomarara uye anochinjika maPCB akaturikidzana. Zvikamu zvinounganidzwa munzvimbo dzakaomarara uye zvakabatanidzwa kune ari padyo akaomeswa mabhodhi kuburikidza nenzvimbo dzinochinjika. Kubatana pakati pezvikamu zvinounzwa kuburikidza neakapfava nemaburi.

Iyo rigid-flex yekugadzira maitiro inosanganisira anotevera matanho:

1. Gadzirira iyo substrate: Nhanho yekutanga mune yakaomesesa-flex maitiro ekugadzira ndeyekugadzirira kana kuchenesa laminate. Ingave kana kwete pane adhesive coating, laminates ane mhangura akaturikidzana anofanirwa kucheneswa asati aiswa mune mamwe maitiro ekugadzira.
2. Patani yekugadzira: Inoitwa kuburikidza nekudhinda skrini kana kufungidzira kwemifananidzo.
3. Etching process: Mativi ese ari maviri e laminate ane redunhu pateni anonyudzwa mu etching tangi kana kupfapfaidza ne etching agent solution ye etching.
4. Mechanical drilling process: Precision drilling masisitimu kana kuchera kwehunyanzvi kunoshandiswa kuchera makomba anodiwa edunhu, mapadhi, uye nemapatani epaburi mumapaneli ekugadzira. Semuenzaniso, laser drilling tekinoroji.
5. Copper plating process: Tarisiro yemhangura yekuisa nzira ndeyekuisa iyo mhangura inodiwa mukati meakaputirwa nemaburi kuti agadzirise mabatiro emagetsi pakati pezvikamu zveiyo rigid-flex board.
6. Isa chivharo chivharo: Iyo yekuvhara layer zvinhu (kazhinji polyimide firimu) uye anonamira anodhindwa pamusoro peiyo rigid-flex board kuburikidza nekudhindwa kwescreen.
7. Cover layer lamination: Lamination inoitwa pane chaiyo tembiricha, kudzvanywa, uye vacuum miganho kuti ive nechokwadi chekunamira kwakaringana kwechifukidziro.
8. Nyorera mbabvu dzekusimbisa: Kuwedzera mbabvu dzekusimbisa dzinogona kuiswa pamberi pekuwedzera kwekugadzirisa, zvichienderana nezvinodiwa zvekugadzira zveiyo rigid-flex board.
9. Flexible board yekucheka: Shandisa hydraulic punching nzira kana nyanzvi yekubaya mapanga kucheka bhodhi rinoshanduka kubva pane yekugadzira.
10. Kuyedzwa kwemagetsi uye kusimbiswa: Rigid-flex mabhodhi anoyedzwa nemagetsi zvinoenderana neIPC-ET-652 nhungamiro yekusimbisa mashandiro ekudzivirira, kubatana, mhando, uye kuita kwebhodhi redunhu zvinosangana nezvinodiwa zvemagadzirirwo edhizaini. Nzira dzekuyedza dzinosanganisira kubhururuka kuferefeta kuyedzwa uye grid yekuyedza masisitimu.

Iyo yakaomesesa-inochinjika yekugadzira maitiro isarudzo yakanaka yekuvaka maseketi mumaindasitiri ekurapa, aerospace, emauto, uye enharembozha nekuti aya mabhodhi edunhu ane mashandiro akanaka uye mabasa chaiwo, kunyanya munzvimbo dzakaoma.

Mainjiniya vanowanzo simbisa nyaya iyi pamwe chete nekugadzirwa kwedunhu rinochinjika uye manotsi ePCB esimba rekuchinja magetsi pavanenge vachigadzira PCB kana PCBA yakavimbika.
