Cov yam ntxwv ntawm ob tog Circuit Court board
Ib leeg-sab Circuit Court board thiab ob-sided circuit board nyob rau hauv qhov sib txawv yog tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm tooj liab sib txawv.Lub rooj tsavxwm ob tog yog lub rooj tsavxwm ntawm ob sab ntawm cov tooj liab, tuaj yeem dhau ntawm lub qhov los ua lub luag haujlwm txuas.Ib leeg tsuas yog ib txheej ntawm tooj liab, tsuas yog ua tau ib txoj kab yooj yim xwb, lub qhov ua tau tsuas yog siv rau plug-in tsis tuaj yeem conduction.
Cov kev xav tau ntawm ob tog ntawm lub rooj tsavxwm yog qhov kev sib txuas ntawm txoj kab uas hla yuav loj dua, qhov me me txoj kab uas hla, metalized qhov qhov txoj kab uas hla kuj tau me dua.Txheej thiab txheej txheej kev sib txuas yog nyob ntawm qhov metallization qhov, qhov zoo yog ncaj qha cuam tshuam rau kev ntseeg siab ntawm cov ntawv luam tawm Circuit Board.
Nrog rau qhov txo qis ntawm qhov aperture, qhov qub rau qhov loj dua qhov aperture tsis cuam tshuam rau cov khib nyiab, xws li kev sib tsoo cov khib nyiab, volcanic tshauv, ib zaug seem nyob rau hauv lub qhov me me hauv, yuav ua rau cov tshuaj nag lossis daus tooj liab, tooj liab plating kom poob cov nyhuv, lub qhov. tsis muaj tooj liab, dhau los ua lub qhov metallization ntawm tus neeg tua neeg tuag.
Ob chav sided circuit board vuam txoj kev
Muab ob npaug rau-sided Circuit Court board thiaj li yuav xyuas kom meej tias ob-sided Circuit Court muaj ib tug txhim khu kev qha conductive nyhuv, peb xav kom koj yuav tsum xub siv nyob ntawm tej thiab xws li welding qhov kev twb kev txuas ntawm lub vaj huam sib luag ob sab (piv txwv li, txheej txheem metalization los ntawm lub qhov ib feem), thiab txiav qhov kev sib txuas ntawm txoj kab nqes protruding ib feem, thiaj li tsis mus stab tus neeg teb xov tooj tes, uas yog lub rooj tsavxwm kev sib txuas npaj ua haujlwm.
Ob-sided Circuit Board welding tseem ceeb
1. Muaj qhov yuav tsum tau ua rau lub shaping ntawm lub cuab yeej yuav tsum ua raws li cov kev cai ntawm cov txheej txheem kos duab rau cov txheej txheem;uas yog, thawj shaping tom qab lub plug-in.
2. Tom qab shaping lub diode qauv sab yuav tsum fim, yuav tsum tsis muaj inconsistency nyob rau hauv ntev ntawm ob tus pins.
3. cov khoom siv nrog polarity yuav tsum tau muab tso rau hauv kev saib xyuas nws cov polarity yuav tsum tsis txhob muab tso rau hauv thim rov qab, yob kev sib xyaw thaiv cov khoom, tom qab ntxig, txawm tias ntsug lossis dag, yuav tsum tsis muaj qhov pom tseeb qaij.
4. soldering hlau hwj chim ntawm 25 mus rau 40W, soldering hlau taub hau kub yuav tsum tau tswj ntawm txog 242 ℃, qhov kub yog siab dhau heev lawm lub taub hau yooj yim "tuag", qhov kub yog tsawg tsis tau yaj lub solder, soldering sij hawm tswj nyob rau hauv 3 mus rau 4. vib nas this.
5.Reflow qhov cub or yoj soldering tshuabformal welding feem ntau yog ua raws li cov cuab yeej los ntawm luv mus rau siab, los ntawm sab hauv mus rau sab nraud ntawm lub vuam txoj hauv kev ua haujlwm, vuam lub sij hawm rau tus tswv, ntev dhau lawm yuav hlawv cov cuab yeej, tseem yuav hlawv cov tooj liab clad kab ntawm tooj liab clad. lub rooj tsavxwm.
6. Vim tias nws yog ob sab welding, yog li yuav tsum tau ua cov txheej txheem ntawm kev muab lub rooj tsav xwm Circuit Court thav duab thiab lwm yam, lub hom phiaj tsis yog nias lub oblique hauv qab ntawm lub cuab yeej.
7. Tom qab ua tiav ntawm lub Circuit Court board soldering yuav tsum tau xyuas kom meej ntawm tus naj npawb ntawm cov hom, xyuas qhov chaw uas muaj ib tug xau ntawm insertion thiab to ntawm vuam, kom paub meej tias lub Circuit Court board redundant pab kiag li lawm xws li pin trimming, tom qab. ntws mus rau hauv cov txheej txheem tom ntej.
8, hauv kev ua haujlwm tshwj xeeb, yuav tsum nruj me ntsis ua raws li cov txheej txheem cuam tshuam los ua haujlwm kom ntseeg tau qhov zoo ntawm cov khoom vuam.
Nrog rau kev loj hlob sai ntawm high-tech, thiab cov pej xeem muaj kev sib raug zoo nrog cov khoom siv hluav taws xob nyob rau hauv kev txuas ntxiv txuas ntxiv, cov pej xeem kuj xav tau kev ua haujlwm siab, me me, ntau yam khoom siv hluav taws xob, uas tso tawm cov kev xav tau tshiab rau lub rooj tsav xwm hauv Circuit Court.
Yog li ntawd, ob tog Circuit Court board tau yug los, vim yog kev siv dav ntawm ob tog ntawm lub rooj tsavxwm, ua rau cov ntawv luam tawm Circuit Board raug tsim los rau lub teeb, nyias, luv, me me.
