Dual in-line pob (Lus Askiv: dual in-line pob), tseem hu ua DIP pob lossis DIP pob, hu ua DIP lossis DIL, yog ib txoj hauv kev ntim rau kev sib xyaw ua ke. Muaj ob kab sib luag ntawm cov hlau pins hu ua headers. DIP cov khoom ntim tau tuaj yeem raug soldered hauv qhov-qhov plated ntawm cov ntawv luam tawm los yog muab tso rau hauv DIP sockets.
DIP-packaged Cheebtsam feem ntau hu ua DIPn luv luv, qhov twg n yog tus naj npawb ntawm pins, piv txwv li, kaum plaub-pin integrated circuit hu ua DIP14.
Integrated circuits feem ntau tau ntim rau hauv DIP, thiab lwm yam khoom siv feem ntau siv DIP ntim xws li DIP keyboards, LEDs, xya ntu qhia, strips, thiab relays. Cables ntawm khoos phis tawj thiab lwm yam khoom siv hluav taws xob kuj tseem siv nyob rau hauv DIP-packed connectors.
Cov khoom ntim DIP ntxov tshaj plaws tau tsim los ntawm Bryant Buck Rogers ntawm Fairchild Semiconductor hauv xyoo 1964. Thawj cov khoom muaj 14 tus pins, uas zoo ib yam li niaj hnub no cov khoom ntim DIP. Nws cov duab yog rectangular. Piv nrog rau cov khoom qub dhau los, cov khoom sib dhos tuaj yeem ua rau kom qhov ntom ntom ntawm cov khoom hauv lub rooj tsavxwm. DIP cov khoom ntim khoom kuj tseem tsim nyog rau cov khoom siv sib dhos ua ke. Nws tuaj yeem muaj ntau ntau txog ntau pua ICs ntawm lub rooj tsavxwm. Txhua qhov chaw yog soldered los ntawm yoj soldering tshuab, thiab tom qab ntawd sim los ntawm cov khoom siv ntsuas tsis siv neeg, tsuas yog xav tau me me ntawm phau ntawv ua haujlwm. Qhov loj ntawm DIP tivthaiv yog qhov loj tshaj qhov sib xyaw ua ke hauv nws. Thaum kawg ntawm lub xyoo pua 20th, nto mount technology (SMT) ntim cov khoom tuaj yeem txo qhov loj thiab qhov hnyav ntawm lub cev. Txawm li cas los xij, cov khoom siv DIP tseem siv tau rau qee lub sijhawm. Piv txwv li, thaum ua cov qauv hauv Circuit Court, DIP Cheebtsam yog siv los ua cov qauv hauv Circuit Court nrog breadboards los pab txhawb kev ntxig thiab tshem tawm cov khoom.
DIP ntim cov khoom yog lub ntsiab ntawm kev lag luam microelectronics hauv xyoo 1970 thiab 1980s. Nyob rau hauv lub xyoo pua 21st thaum ntxov, kev siv tau maj mam txo, tau hloov los ntawm cov pob khoom siv thev naus laus zis xws li PLCC thiab SOIC. Cov yam ntxwv ntawm cov khoom siv thev naus laus zis saum npoo av tsim nyog rau kev tsim khoom loj, tab sis tsis yooj yim rau kev tsim hluav taws xob. Txij li qee cov khoom siv tshiab tsuas yog muab cov khoom lag luam hauv cov pob khoom siv thev naus laus zis, ntau lub tuam txhab tsim cov khoom hloov pauv uas hloov SMT cov khoom rau hauv pob khoom DIP, thiab ICs hauv cov pob khoom siv thev naus laus zis tuaj yeem muab tso rau hauv cov khoom siv, xws li DIP Cov khoom ntim tau txuas nrog lub breadboard lossis Lwm cov qauv qauv hauv Circuit Court (xws li perfboard) uas phim cov khoom hauv kab.
Rau cov programmable Cheebtsam xws li EPROM lossis GAL, DIP-packed Cheebtsam tseem nrov rau ib ntus vim tias lawv yooj yim rau hlawv cov ntaub ntawv los ntawm cov khoom siv hluav taws xob sab nraud (DIP ntim cov khoom tuaj yeem ncaj qha tso rau hauv qhov sib thooj DIP ntawm cov khoom siv hlawv). . Txawm li cas los xij, nrog kev muaj koob meej ntawm kev ua haujlwm hauv kab (ISP) thev naus laus zis, cov txiaj ntsig ntawm kev ua haujlwm yooj yim ntawm DIP pob khoom tsis tseem ceeb lawm. Hauv xyoo 1990, cov khoom siv nrog ntau tshaj 20 tus pins tseem tuaj yeem muaj DIP ntim khoom. Nyob rau hauv lub xyoo pua 21st, ntau yam programmable tshiab tau ntim rau hauv SMT, thiab cov khoom hauv DIP pob tsis muaj lawm.
Mounting txoj kev:
DIP pob khoom tuaj yeem ntsia tau rau ntawm lub rooj tsav xwm hauv Circuit Court los ntawm kev siv tshuab los ntawm lub qhov, thiab tseem tuaj yeem ntsia tau los ntawm kev siv cov khoom siv DIP. Kev siv cov khoom siv DIP tuaj yeem pab txhawb kev hloov cov khoom, thiab tuaj yeem zam dhau qhov kub ntawm cov khoom thaum lub sij hawm soldering. Feem ntau, lub qhov (socket) yuav raug siv nrog ib qho kev sib xyaw ua ke nrog lub ntim loj dua lossis cov nqi siab dua. Rau cov khoom siv kuaj lossis cov programmers, qhov twg nws yog qhov tsim nyog rau nruab thiab tshem tawm cov kev sib xyaw ua ke, cov khoom siv xoom-tiv taus yog siv. DIP pob khoom tseem tuaj yeem siv nrog breadboards, uas feem ntau yog siv rau kev qhia, kev tsim kho lossis kev tsim qauv.
Tab sis yog tias koj xav tau kho lossis rov kho dua, cov cuab yeej tshaj lij yog qhov tsim nyog, piv txwv li:
