Yuav Ua Li Cas Xaiv Ib Lub Txuas Txuas Zoo Rau Kev Siv Kho vajtse?

Yuav ua li cas xaiv ib tug connector haum rau hardware daim ntawv thov?

Lub connector zoo li cov haujlwm interface ntawm qhov program. Yog tias tus qauv tsim tsim nyog, kev saib xyuas cov khoom lag luam yav tom ntej, kev hloov kho tshiab, thiab kev hloov pauv yuav tau txais ob zaug qhov txiaj ntsig nrog ib nrab ntawm kev siv zog, kom cov khoom tuaj yeem tswj tau qhov tseem ceeb ntawm qhov ntev; qhov tsim tsis tsim nyog yuav ua rau muaj kev nyuaj siab rau yav tom ntej txij nkawm thiab kev txhim kho, uas yuav cuam tshuam rau tag nrho lub cev. Z nws thiaj li ua rau cov khoom poob kev sib tw, thiab qhov tseem ceeb ntawm cov khoom sib txuas yog qhov tseeb ntawm tus kheej.

Connectors, uas feem ntau hu ua connectors los ntawm engineers, yog siv los txuas ob lub Circuit Court boards los yog cov khoom siv hluav taws xob kom ua tiav lub zog lossis teeb liab. Los ntawm kev sib txuas, lub voj voog tuaj yeem hloov kho, cov txheej txheem sib dhos ntawm cov khoom siv hluav taws xob tuaj yeem ua kom yooj yim, thiab cov khoom siv tau yooj yim tswj thiab kho dua tshiab.

Rau modular circuits, xaiv cov connectors plays lub luag hauj lwm tseem ceeb. Yog li thaum xaiv connectors, los ntawm cov ces kaum twg peb yuav tsum xav txog cov connectors haum rau kev siv kho vajtse?

1. Pins thiab qhov sib txawv

Tus naj npawb ntawm tus pins thiab qhov sib nrug ntawm tus pins yog lub hauv paus rau kev xaiv cov khoom sib txuas. Tus naj npawb ntawm tus pins los xaiv lub connector yog nyob ntawm tus naj npawb ntawm cov teeb liab uas yuav tsum tau txuas. Rau qee qhov sib txuas sib txuas, tus naj npawb ntawm cov pins hauv thaj chaw headers raws li qhia hauv daim duab hauv qab no yuav tsum tsis txhob ntau dhau. Vim hais tias nyob rau hauv cov txheej txheem soldering ntawm lub tshuab muab tso rau, vim yog kub, connector yas yuav rhuab thiab deformed, thiab nyob rau hauv nruab nrab ib feem yuav bulge, uas ua rau tsis muaj tseeb soldering ntawm cov pins. Peb P800Flash programmer siv hom header thiab poj niam header los txuas ntawm cov laug cam nyob rau theem pib ntawm kev loj hlob. Raws li qhov tshwm sim, cov pins ntawm tus qauv qauv header tau soldered nyob rau hauv ib cheeb tsam loj. Tom qab hloov mus rau 2 tus pin headers nrog halved pins, tsis muaj cuav soldering.

Niaj hnub no, cov khoom siv hluav taws xob tau tsim los ntawm kev ua haujlwm me me thiab qhov tseeb, thiab tus pin pitch ntawm lub connector kuj tau hloov ntawm 2.54mm mus rau 1.27mm thiab tom qab ntawd mus rau 0.5mm. Qhov me me ntawm cov hlau lead suab, qhov siab dua qhov yuav tsum tau ua rau cov txheej txheem ntau lawm. Qhov sib nrug ntawm cov hlau lead yuav tsum tau txiav txim los ntawm lub tuam txhab' qib kev tsim khoom siv tshuab. Qhov muag tsis pom kev ntawm qhov sib txawv me me yuav ua rau muaj teeb meem hauv kev tsim khoom thiab kev saib xyuas.

2. Kev ua haujlwm hluav taws xob

Kev ua haujlwm hluav taws xob ntawm cov khoom txuas feem ntau suav nrog: txwv tam sim no, tiv thaiv kev tiv thaiv, rwb thaiv tsev tsis kam thiab dielectric zog, thiab lwm yam. Thaum txuas lub zog hluav taws xob siab, xyuam xim rau qhov txwv tam sim no ntawm lub connector; Thaum xa cov teeb liab siab xws li LVDS, PCIe, thiab lwm yam, xyuam xim rau kev tiv thaiv kev tiv thaiv. Lub connector yuav tsum muaj qhov sib tiv tauj tsawg thiab tsis tu ncua, feem ntau kaum ntawm mΩ mus rau pua pua mΩ.

3. Kev ua haujlwm ib puag ncig

Kev ua haujlwm ib puag ncig ntawm cov khoom txuas feem ntau suav nrog: kev tiv thaiv kub, av noo, tshuaj tsuag ntsev, kev co, kev poob siab, thiab lwm yam. Xaiv raws li kev thov ib puag ncig. Yog hais tias daim ntawv thov ib puag ncig yog cov av noo, qhov yuav tsum tau ua rau cov av noo thiab ntsev tsuag ntawm lub connector yog siab los tiv thaiv cov hlau hu ntawm connector los ntawm corroded. Hauv kev tswj hwm kev lag luam, qhov yuav tsum tau ua rau kev tiv thaiv kev vibration thiab kev poob siab ntawm lub connector yog siab, thiaj li tiv thaiv lub connector los ntawm ntog tawm thaum lub sij hawm vibration txheej txheem.

4. Mechanical zog

Cov khoom siv hluav taws xob ntawm cov khoom sib txuas muaj xws li kev siv dag zog, mechanical foolproofness, thiab lwm yam. Mechanical foolproof tseem ceeb heev rau lub connector. Thaum ntsaws rau hauv rov qab, nws yuav ua rau irreversible kev puas tsuaj rau lub Circuit Court!

Lub zog ntxig yog muab faib ua lub zog ntxig thiab sib cais quab yuam. Cov txheej txheem tsim nyog tau teev tseg Z loj ntxig quab yuam thiab Z me me sib cais quab yuam. Los ntawm kev xav ntawm kev siv, lub zog ntxig yuav tsum me me thiab lub zog sib cais yuav tsum loj. Kev sib cais me me yuav txo qis kev ntseeg tau ntawm kev sib cuag, tab sis rau cov khoom sib txuas uas feem ntau yuav tsum tau ntsaws thiab tshem tawm, kev sib cais quab yuam ntau dhau yuav ua rau qhov nyuaj ntawm kev tshem tawm thiab txo cov neeg kho tshuab lub neej.
