Dab tsi yog cov yam ntxwv ntawm daim ntawv thov kev kho mob PCB?

Muaj ntau yam khoom siv kho mob, xws li los ntawm cov cuab yeej zoo tib yam mus rau ntau cov cuab yeej siv. Hom kev kuaj mob thiab kev kho mob no tuaj yeem muab faib ua peb pawg:

Chav Kawm 1: Cov khoom siv kho mob dav dav.

Cov khoom no feem ntau muaj kev pheej hmoo tsawg. Txawm hais tias lawv siv qee txoj kev kuaj mob thiab kev kho mob, nws nyuaj rau ua rau raug mob, xws li cov nplais hluav taws xob, daim npav ntsuas thiab tsom iav qhov muag.

Chav Kawm 2: Cov cuab yeej tshwj xeeb rau kev kuaj mob thiab kho nrog qee yam kev pheej hmoo.

Qhov kev pheej hmoo ntawm cov khoom no yog siab dua li ntawm thawj cov khoom, tab sis tsuas yog txwv rau kev ua haujlwm tiag tiag thiab kev saib xyuas kev pheej hmoo, xws li lub rooj zaum fais fab thiab cov saib xyuas.

Chav Kawm 3: Lub neej txhawb nqa tshuab thiab khoom siv.

Cov khoom no yog qhov tseem ceeb thiab yuav tsum tau tsim ua raws li qhov tshwj xeeb tshaj plaws kom ntseeg tau tias nws muaj kev ntseeg siab. Thaum lub neej ntawm cov tshuab thiab cov cuab yeej siv no raug txiav lossis tsis ua haujlwm, lawv yuav ua rau muaj kev puas tsuaj loj, xws li cov hlab plawv stents thiab lub plawv li qub. Peb paub tias cov khoom siv kho mob yuav tsum ua kom tau raws li cov kev qhia tshwj xeeb, thiab tib lub sijhawm muab qee qhov kev qhia tshwj xeeb, txawm tias nyob rau hauv lub luag haujlwm, kev tsim khoom lossis kev tswj hwm qib zoo. PCB tsim siv rau kev kuaj mob thiab kev kho mob yuav tsum muaj cov khoom siv hluav taws xob tshwj xeeb kom ua tiav cov yam ntxwv tshwj xeeb uas tau teev tseg los ntawm cov khoom siv hluav taws xob, cov ntaub ntawv teeb liab zoo, crosstalk thiab cov khoom siv hauv av, tab sis qhov tseem ceeb tshaj plaws yog nws txoj kev ruaj ntseg thiab kev nyab xeeb. Kev nyab xeeb yog qhov teeb meem tseem ceeb, suav nrog cov hluav taws xob hluav taws xob, cov yam ntxwv ntawm cov khoom siv hluav taws xob, cov yam ntxwv thermal thiab cov cuab yeej siv kho tshuab kev nyab xeeb, tag nrho cov uas tau tsav los ntawm IPC Qib 3 specifications. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum muaj lub chaw tsim khoom PCB txhim khu kev qha los muab kev ntseeg siab PCB rau cov khoom siv kho mob rau kev kuaj mob thiab kev kho mob.
