zvose zviri zviviri akaomarara uye anochinjika akadhindwa wedunhu mabhodhi (PCBS) inoshandiswa kubatanidza zvigadzirwa zvemagetsi mumhando dzakasiyana dzevatengi uye zvisiri zvevatengi. Seizvo zita rinoratidzira, yakaomarara pcb ibhodhi redunhu rakavakirwa pane yakaomarara hwaro hwesimbi iyo isingagone kukotama, nepo PCB inoshanduka (inozivikanwawo sedunhu rinochinja-chinja) yakavakirwa pachigadziko chinoshanduka chinogona kukotama, kumonyanisa, uye kupeta.

Kunyangwe zvese zviri zvechinyakare uye zvisingachinjiki PCBS zvichishandira zvakafanana zvakakosha chinangwa, zvakakosha kuti uzive kuti kune misiyano mizhinji pakati pavo. Flexible macircuit haasi chete akakombama PCBS; zvakagadzirwa zvakasiyana nePCBS yakaoma uye zvine akasiyana maitiro ekuita pamwe nekuipira. Dzidza zvakawanda nezve akaomarara uye anochinja PCBS pazasi.

Ndeupi musiyano uripo pakati peyakaomarara pcb uye inoshanduka dunhu?

Rigid PCBS, inowanzo kunzi PCBS, ndizvo zvinofungwa nevanhu vazhinji pavanofunga nezvemabhodhi ematunhu. Mahwendefa aya anobatanidza zvinhu zvemagetsi achishandisa njanji dzinoitisa uye zvimwe zvinhu zvakarongedzwa pane isina-conductive substrate. Pamabhodhi ematunhu akaomarara, iyo isiri-inoitisa substrate inowanzo iine girazi rinowedzera kusimba kwebhodhi uye rinopa simba uye kuomarara. Iwo akaomarara wedunhu bhodhi anopa tsigiro yakanaka kugungano uye inopa yakanaka yekupisa kupisa.

Rudzi urwu rwebhodhi redunhu rinoshandisa inochinjika substrate, senge polyimide, kunyangwe inoshanduka PCBS zvakare ine maitiro ekuitisa pane isiri-inoitisa substrate. Iyo inochinjika base inobvumira inoshanduka macircuit kumira vibrations, kudzima kupisa uye kupeta kuita akasiyana maumbirwo. Nekuda kwekukosha kwayo kwechimiro, maseketi anoshanduka-shanduka ari kuramba achishandiswa mukuumbana uye zvigadzirwa zvemagetsi zvigadzirwa.

Kuwedzera kune izvo zvinhu uye kuomarara kweiyo base layer, misiyano yakakura pakati pePCB nedunhu rinoshanduka rinosanganisira:

Inoitisa zvinhu: Nekuti maseketi anoshanduka anofanirwa kuve akakombama, vagadziri vanogona kushandisa yakapfava yakakungurudzwa yakafukidzwa mhangura panzvimbo ye conductive mhangura.

L Kugadzira maitiro: Flexible pcb vagadziri havashandise solder ichivharira mafirimu, asi panzvimbo pezvo shandisa nzira inonzi kufukidza, kana kufukidza, kuchengetedza dunhu rakafumurwa rePCB inochinja.

Chaicho mutengo: Masekete anochinja-chinja anodhura zvakanyanya kupfuura mabhodhi akaomarara. Asi nekuti mabhodhi anochinjika anokwanisa kuiswa munzvimbo dzakaomarara, mainjiniya anogona kudzora saizi yezvigadzirwa zvavo, nokudaro nenzira isina kunangana vachichengetedza mari.

Maitiro ekusarudza pakati peyakaomarara uye inoshanduka pcb

Rigid uye inoshanduka mabhodhi inogona kushandiswa mune zvakawanda zvakasiyana zvigadzirwa, kunyangwe mamwe mashandiro anogona kubatsirwa zvakanyanya kubva kune imwe mhando yebhodhi. Semuenzaniso, PCBS yakaoma inonzwisisika muzvigadzirwa zvikuru (zvakaita seTV uye makomputa edesktop), nepo zvimwe zvigadzirwa zvakaomarara (senge mafoni emagetsi uye tekinoroji inopfeka) zvinoda macircuit anochinjika.

Paunenge uchisarudza pakati pebhodhi rakaomarara nePCB inochinjika, funga zvaunoda zvekushandisa, indasitiri yakasarudzika bhodhi mhando, uye mhedzisiro yekushandisa imwe mhando kana imwe iyo inogona kubatsira.
