Qhia
Thaum nws los txog rau kev tu thiab tu, ntau tus neeg siv PCB tsis paub meej tias cov boards rigid-flex tuaj yeem ntxuav lossis ntxuav yam tsis muaj kev puas tsuaj.Hauv tsab ntawv blog no, peb yuav nkag mus rau hauv lub ncauj lus no los muab koj cov kev pom zoo thiab kev taw qhia.Yog li cia peb pib!
Printed Circuit Boards (PCBs) yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no.Lawv muab kev sib txuas hluav taws xob thiab kev txhawb nqa rau ntau yam khoom.Raws li kev siv thev naus laus zis, ntau qhov nyuaj thiab ntau yam PCB tsim tau tshwm sim, suav nrog cov PCB nruj.Cov laug cam no ua ke cov khoom tsis sib xws thiab hloov tau yooj yim los muab kev ua haujlwm zoo dua qub thiab siv tau.
Kawm paub txog rigid-flex boards
Ua ntej peb tham txog cov txheej txheem ntxuav ntawm cov rigid-flex boards, nws yog ib qho tsim nyog yuav tsum nkag siab txog lawv cov qauv thiab muaj pes tsawg leeg.Rigid-flex PCBs yog tsim los ntawm ntau txheej txheej ntawm cov ntaub ntawv nruj thiab hloov tau yooj yim, xws li FR-4 thiab polyimide.Cov khaubncaws sab nraud povtseg yog sib txuas nrog siv plated los ntawm qhov thiab cov flex connectors.Lawv muab qhov zoo xws li qhov chaw txuag, nce durability thiab txhim kho kev ntseeg tau.
Vim li cas thiaj ntxuav rigid-flex boards?
Zoo li lwm yam PCB, cov boards nruj-flex tuaj yeem sau cov plua plav, av, thiab lwm yam khoom paug thaum lub sijhawm tsim khoom lossis thaum siv.Cov kab mob no tuaj yeem cuam tshuam rau PCB kev ua haujlwm thiab kev ua haujlwm ntev.Yog li ntawd, kev tu tsis tu ncua yog tsim nyog los tswj kev ua haujlwm zoo thiab tiv thaiv cov teeb meem uas yuav tshwm sim.
Yuav ua li cas ntxuav rigid-flex boards
Thaum ntxuav cov rigid-flex boards, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov txheej txheem tsim nyog thiab kev ceev faj kom tsis txhob ua rau lub rooj tsavxwm puas.Nov yog qee qhov kev pom zoo rau kev ntxuav cov laug cam:
1. Isopropyl cawv (IPA) txoj kev:Txoj kev no yuav tsum maj mam so lub PCB nto nrog ib daim ntaub tsis muaj lint lossis paj rwb swab dipped hauv IPA daws.IPA yog ib qho kuab tshuaj uas nquag siv uas tshem tawm cov kab mob tsis muaj qhov seem.Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum siv qhov tsawg kawg nkaus ntawm IPA thiab tsis txhob ya raws ntau dhau vim nws tuaj yeem nkag mus rau thaj chaw flex thiab ua rau muaj kev puas tsuaj.
2. Ultrasonic tu:Ultrasonic tu yog ib txoj kev siv feem ntau hauv PCB tu.Nws koom nrog rau immersing lub PCB nyob rau hauv ib tug tu tov thaum ultrasonically kho nws.Cov kev vibrations tsim los ntawm cov nthwv dej tshem tawm cov kab mob thiab ntxuav lub rooj tsav xwm hauv Circuit Court kom zoo.Txawm li cas los xij, kev ceev faj heev yuav tsum tau siv thaum siv txoj kev no vim tias overheating lossis overpressure tuaj yeem ua rau qhov hloov pauv ntawm PCB.
3. Vapor theem tu:Vapor theem tu yog lwm txoj hauv kev zoo rau kev ntxuav cov rigid-flex boards.Cov txheej txheem cuam tshuam nrog kev nthuav tawm PCB rau vaporized nqus tsev vaporized, uas condenses ntawm lub rooj tsavxwm nto thiab dissolves cov kab mob.Cov cuab yeej no ua kom huv si sib sib zog nqus yam tsis muaj kev txhawb nqa kev ya raws.Txawm li cas los xij, nws xav tau cov cuab yeej tshwj xeeb thiab kev txawj ntse, ua rau nws tsis tshua nkag mus rau cov neeg siv nruab nrab.
Kev ceev faj yuav tsum ua raws
Txawm hais tias kev tu vaj tse nruj-flex yog qhov tseem ceeb, nws tseem ceeb heev uas yuav tsum ua raws li qee qhov kev ceev faj kom tsis txhob muaj kev puas tsuaj.Nov yog qee cov lus qhia kom nco qab:
1. Tsis txhob siv cov khoom abrasive:Tsis txhob siv cov khoom abrasive xws li txhuam los yog txhuam cov ntaub so ntswg vim tias lawv tuaj yeem khawb lossis ua rau qhov muag muag ntawm PCB.
2. Tsis txhob muab tso rau PCB hauv dej:Tsis txhob muab tso rau PCB hauv cov kua tshuaj tshwj tsis yog siv txoj kev pom zoo xws li kev ntxuav ultrasonic.Cov dej noo ntau dhau tuaj yeem nkag mus rau hauv qhov chaw flex thiab ua rau puas tsuaj.
3. Ua tib zoo saib xyuas:Yuav tsum tuav PCBs nrog txhais tes huv si thiab tsis txhob khoov lossis khoov lub rooj tsavxwm dhau nws qhov kev txwv vim qhov no yuav ua rau muaj kev ntxhov siab lossis tawg.
Hauv kev xaus:
Hauv cov ntsiab lus, yog, koj tuaj yeem ntxuav lossis ntxuav cov rigid-flex boards, tab sis koj yuav tsum ua raws li txoj hauv kev kom raug thiab ceev faj kom tsis txhob muaj kev puas tsuaj.Kev tu tsis tu ncua pab tswj kev ua haujlwm thiab kev ua haujlwm ntev ntawm cov PCBs siab heev.Txawm hais tias koj xaiv txoj kev IPA, kev tu ultrasonic lossis vapor tu, ceev faj thiab tsis txhob ya raws ntau dhau los yog siab.
Yog tias koj tsis paub meej tias yuav ua li cas ntxuav lub rooj tsavxwm nruj-flex lossis ua lwm yam teeb meem ntsig txog kev saib xyuas, nws raug nquahu kom nrhiav kev pab lossis sab laj nrog PCB cov chaw tsim khoom.Ua kom koj lub PCB huv si thiab tu kom zoo yuav ua kom pom kev ua haujlwm zoo thiab kev ntseeg siab ntawm koj cov khoom siv hluav taws xob.
