PCB board yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, uas suav nrog kev tsim khoom thiab kev sib dhos ntawm cov rooj sib tham. Txawm li cas los xij, hauv cov txheej txheem tsim khoom ntawm PCB cov laug cam, qhov tsis xws luag yog qhov tshwm sim thiab tuaj yeem cuam tshuam rau kev tsim khoom thiab kev ua haujlwm zoo. Yog li ntawd, kev daws qhov teeb meem ntawm PCB pawg thawj coj saib tsis raug thiab txhim kho kev tsim khoom yog qhov tseem ceeb.
Kev tshuaj xyuas ntawm PCB board tsis xws luag thiab lawv cov laj thawj
1. Tshem tawm ntawm epoxy resin ntawm cov ntaub qhwv
Yog vim li cas: Tsis zoo adhesion ntawm lub solder ncoo epoxy resin thiab hauv qab phaj kub kua nplaum, uas ua rau tev ntawm lub solder pad epoxy resin.
Kev daws: Xyuas qhov adhesion ntawm solder pad epoxy resin thiab hauv qab phaj kub kua nplaum, thiab ua haujlwm sib txuas dua.
2. Kev ua tsis zoo ntawm cov ntaub so ntswg
Yog vim li cas: Cov ntaub qhwv ntsej muag tsis zoo nrog lub qhov hauv PCB pawg thawj coj saib.
Kev daws: Kho qhov chaw ntawm cov ntaub so ntswg kom haum nrog lub qhov hauv PCB pawg thawj coj saib.
3. Burr
Yog vim li cas: Kev sib cuag tsis zoo ntawm cov ntawv luam tawm Circuit Board thiab hlau sib tsoo tshuab.
Kev daws: Hloov cov hlau grinder lossis hloov qhov loj ntawm lub rooj tsav xwm luam tawm.
Kev daws teeb meem rau cov teeb meem tshwm sim hauv PCB boards
1. PCB board Circuit Court disconnection
Kev daws: Siv cov cuab yeej kuaj xyuas seb puas muaj kev cuam tshuam hauv Circuit Court, txiav txim siab qhov chaw ntawm qhov kev txiav tawm, thiab tom qab ntawd rov txuas lub voj voog.
2. FPC Circuit Court board ces kaum tawg
Kev daws: Txo qhov hloov pauv ntawm qhov nres nkhaus lossis hloov qhov nkhaus taw tes mus rau txoj kab ncaj nraim.
3. Circuit Board qhib Circuit Court
Kev daws: Siv cov cuab yeej tu los kho nyob ze ntawm qhov chaw qhib hluav taws xob.
4. Kev vuam tsis raug
Kev daws: Xyuas seb txoj hauj lwm ntawm cov ntaub qhwv lub ntsej muag zoo li cas thiab rov ua dua.
5. Cov ntaub qhwv ntsej muag dub
Kev daws: ntxuav lub rooj tsavxwm nrog cawv lossis lwm yam kuab tshuaj.
