Hais txog DIP cov khoom siv, PCB cov neeg ib txhia tsis nto qaub ncaug nrawm!
DIP yog plug-in.Chips ntim rau hauv txoj kev no muaj ob kab ntawm tus pins, uas tuaj yeem ncaj qha welded rau cov khoom siv nrog DIP qauv lossis welded rau vuam txoj haujlwm nrog tib lub qhov.Nws yog qhov yooj yim heev kom paub txog PCB board perforation vuam, thiab muaj kev sib raug zoo nrog cov niam ntawv, tab sis vim nws qhov chaw ntim thiab tuab kuj loj, thiab tus pin nyob rau hauv cov txheej txheem ntawm kev ntxig thiab tshem tawm yog yooj yim rau kev puas tsuaj, tsis muaj kev ntseeg siab.
DIP yog qhov nrov tshaj plaws plug-in pob, daim ntawv thov ntau yam suav nrog cov qauv logic IC, nco LSI, microcomputer circuits, thiab lwm yam. Cov pob ntawv me me (SOP), muab los ntawm SOJ (J-type pin me profile pob), TSOP (nyias me me. pob profile), VSOP (pob profile me me), SSOP (txo SOP), TSSOP (thin txo SOP) thiab SOT (me me profile transistor), SOIC (me me profile integrated circuit), thiab lwm yam.
- Lub PCB pob qhov yog loj dua li cov khoom siv
PCB plug-in qhov thiab pob pin qhov yog kos raws li cov lus qhia tshwj xeeb.Vim tias qhov xav tau ntawm tooj liab plating hauv lub qhov thaum lub sij hawm ua phaj, qhov kev zam dav dav yog ntxiv lossis rho tawm 0.075mm.Yog tias lub PCB ntim lub qhov loj dhau ntawm tus pin ntawm lub cev lub cev, nws yuav ua rau cov khoom tawg, tsis txaus tin, cua vuam thiab lwm yam teeb meem zoo.
Saib daim duab hauv qab no, siv WJ124-3.81-4P_WJ124-3.81-4P (KANGNEX) ntaus tus pin yog 1.3mm, PCB ntim qhov yog 1.6mm, aperture loj dhau ua rau dhau yoj vuam qhov chaw lub sijhawm vuam.
Txuas nrog rau daim duab, yuav WJ124-3.81-4P_WJ124-3.81-4P (KANGNEX) cov khoom raws li tus qauv tsim, tus pin 1.3mm yog qhov tseeb.
- PCB pob qhov yog me dua li cov khoom siv
Plug-in, tab sis yuav lub qhov tsis muaj tooj liab, yog tias nws yog ib leeg thiab ob lub vaj huam sib luag tuaj yeem siv txoj kev no, ib leeg thiab ob lub vaj huam sib luag yog cov hluav taws xob sab nraud, cov khoom siv hluav taws xob tuaj yeem ua tau;Lub plug-in qhov ntawm lub rooj tsavxwm multilayer yog me me, thiab PCB lub rooj tsavxwm tsuas yog tuaj yeem rov ua dua yog tias cov txheej sab hauv muaj hluav taws xob, vim tias cov txheej txheem sab hauv tsis tuaj yeem kho los ntawm reaming.
Raws li pom hauv daim duab hauv qab no, cov khoom ntawm A2541Hwv-3P_A2541HWV-3P (CJT) tau yuav raws li cov qauv tsim.Tus pin yog 1.0mm, thiab PCB sealing ncoo qhov yog 0.7mm, uas ua rau tsis ua hauj lwm rau ntxig.
The components of A2541Hwv-3P_A2541HWV-3P (CJT) are purchased as the design requirements.Tus pin 1.0mm yog lawm.
- Pob pin spacing txawv ntawm qhov sib txawv ntawm cov khoom siv
Lub PCB sealing ncoo ntawm DIP ntaus ntawv tsis tsuas yog muaj tib lub aperture li tus pin, tab sis kuj xav tau qhov kev ncua deb ntawm tus pin qhov.Yog tias qhov sib nrug ntawm tus pin qhov thiab lub cuab yeej tsis sib haum, lub cuab yeej tsis tuaj yeem muab tso rau hauv, tshwj tsis yog rau qhov chaw uas kho tau qhov sib nrug ntawm ko taw.
Raws li pom hauv daim duab hauv qab no, tus pin qhov deb ntawm PCB ntim yog 7.6mm, thiab tus pin qhov nrug ntawm cov khoom yuav yog 5.0mm.Qhov sib txawv ntawm 2.6mm ua rau lub cuab yeej siv tsis tau.
- Lub PCB ntim qhov ze dhau lawm
Hauv PCB tsim, kos duab thiab ntim khoom, nws yuav tsum tau them sai sai rau qhov kev ncua deb ntawm tus pin qhov.Txawm hais tias lub phaj liab qab tuaj yeem tsim tau, qhov kev ncua deb ntawm tus pin qhov me me, nws yog ib qho yooj yim los ua tin luv Circuit Court thaum sib dhos los ntawm yoj soldering.
Raws li pom nyob rau hauv daim duab hauv qab no, luv luv Circuit Court tej zaum yuav tshwm sim los ntawm me me pin nrug.Muaj ntau yam laj thawj rau luv luv Circuit Court nyob rau hauv soldering tin.Yog tias qhov kev sib dhos tuaj yeem tiv thaiv ua ntej ntawm qhov kawg tsim, qhov xwm txheej ntawm cov teeb meem tuaj yeem raug txo.
- Teeb meem piav qhia
Tom qab yoj crest welding ntawm ib yam khoom DIP, nws tau pom tias muaj ib tug loj shortage ntawm tin nyob rau hauv lub solder phaj ntawm tsau ko taw ntawm lub qhov (socket) network, uas belongs rau cua vuam.
- Teeb meem cuam tshuam
Raws li qhov tshwm sim, kev ruaj ntseg ntawm lub network qhov (socket) thiab PCB pawg thawj coj ua phem zuj zus, thiab lub zog ntawm lub teeb liab tus pin ko taw yuav raug siv thaum siv cov khoom, uas nws thiaj li ua rau kev sib txuas ntawm lub teeb liab tus pin ko taw, cuam tshuam rau cov khoom. kev ua tau zoo thiab ua rau muaj kev pheej hmoo ntawm kev ua tsis tiav hauv kev siv cov neeg siv.
- Teeb meem txuas ntxiv
Kev ruaj ntseg ntawm lub qhov (socket) lub network tsis zoo, qhov kev sib txuas ntawm lub teeb liab tus pin yog qhov tsis zoo, muaj teeb meem zoo, yog li nws yuav ua rau muaj kev nyab xeeb txaus ntshai rau tus neeg siv, qhov kawg poob yog qhov tsis txaus ntseeg.
- Muaj ntau yam teeb meem ntsig txog DIP ntaus pins, thiab ntau lub ntsiab lus tseem ceeb yog qhov yooj yim kom tsis quav ntsej, ua rau lub rooj zaum zaum kawg.Yog li yuav ua li cas sai thiab daws cov teeb meem zoo li no ib zaug thiab rau tag nrho?
- Ntawm no, kev sib dhos thiab kev tshuaj xyuas kev ua haujlwm ntawm peb CHIPSTOCK.TOP software tuaj yeem siv los ua kev tshuaj xyuas tshwj xeeb ntawm cov pins ntawm DIP li.Cov khoom kuaj xyuas suav nrog tus lej pins los ntawm qhov, qhov loj ntawm THT pins, qhov txwv me me ntawm THT pins thiab cov yam ntxwv ntawm THT pins.Cov khoom soj ntsuam ntawm cov pins pib npog cov teeb meem tshwm sim hauv kev tsim cov khoom siv DIP.
- Tom qab ua tiav ntawm PCB tsim, PCBA sib dhos tsom xam muaj nuj nqi tuaj yeem siv los tshawb pom cov qauv tsim ua ntej, daws cov qauv tsim ua ntej tsim khoom, thiab zam kev tsim teeb meem hauv cov txheej txheem sib dhos, ncua sij hawm ntau lawm thiab pov tseg kev tshawb fawb thiab kev tsim kho cov nqi.
- Nws cov kev soj ntsuam kev sib dhos muaj 10 yam tseem ceeb thiab 234 cov khoom zoo tshuaj xyuas cov cai, npog tag nrho cov teeb meem sib dhos, xws li kev txheeb xyuas cov cuab yeej, kev txheeb xyuas tus pin, ntsuas ntsuas phoo, thiab lwm yam, uas tuaj yeem daws ntau qhov xwm txheej ntau lawm uas cov engineers tsis tuaj yeem xav txog ua ntej.
