Sab hauv yam
(1) Circuit Court tsim: tsis tsim nyog Circuit Circuit Court Circuit Court yuav ua rau cov chaw xa tawm tam sim no, thiab yog li ua rau tooj liab blistering. Piv txwv li, cov ntsiab lus xws li kab dav, thiab aperture tsis tau mloog dhau los hauv cov khoom siv hluav taws xob ntau thaum lub sijhawm kis tau tus mob ntau zaus.
(2) Cov Thawj Coj tsis zoo: Tus Pcb Board zoo tsis tau raws li cov ntaub ntawv luam tawm, thiab lwm yam tuaj yeem ua rau cov tawv nqaij tooj liab los tev tawm los ntawm substrate thiab daim npuas facks.
Exsinsic yam
(1) ib puag ncig cov ntsiab lus: Cov huab cua siab av noo lossis qhov cua tsis zoo kuj tseem tuaj yeem ua rau tooj liab ntawv rau npuas. Piv txwv li, thaum PCB cov laug cam yog khaws cia lossis tsim cov av ntawm cov ntawv ci thiab lub substrate, ua rau lub tooj liab ntawv ci kom npuas. Tsis tas li ntawd, thaum lub chaw tsim khoom ntau lawm tuaj yeem ua rau cua sov ntxiv thiab ua kom nrawm nrawm ntawm tooj liab ntawm tooj liab cov nplooj ntawv.
(2) ua qhov kub thiab txias: thaum lub sijhawm ua haujlwm ntau dhau los yog qhov tsis tshua muaj siab, tus tsim cov oxides thiab bubbles thaum tam sim no ntws los ntawm. Cov cua sov tsis sib xws tseem yuav ua rau muaj kev deformation nyob rau saum npoo ntawm PCB board, ua rau kev tsim cov npuas.
(3) cov khoom txawv teb chaws ntawm qhov chaw: Thawj hom tooj liab ntawv muaj roj stains muaj nyob rau hauv lub xeev tsis muaj roj, ua rau muaj kev tsim cov oxides thiab cov npuas dej thaum tam sim no ntws los ntawm nws; Qhov thib ob ntawm tooj liab daim tawv muaj npuas ntawm nws cov nplaim dej, uas tseem tuaj yeem ua rau cov tawv nqaij tooj liab rau npuas; Qhov thib peb hom ntawm daim tawv nqaij tooj liab tau tawg rau saum npoo av, uas tseem tuaj yeem ua rau cov tawv nqaij tooj liab rau npuas.
(4) Cov Txheej Txheem Tshwj Xeeb: Thaum lub sijhawm ua tiav lawm, tej zaum yuav muaj kev nce qib ntawm qhov tsis zoo ntawm cov khoom ntawm cov khoom txawv teb chaws, thiab muaj peev xwm xau ntawm substrate los ntawm lub qhov.
(5) qhov tseem ceeb tam sim no: thaum lub sijhawm ua haujlwm hluav taws xob, tsis xwm yeem tam sim no tuaj yeem ua rau lub tshuab hluav taws xob yuav ua rau muaj kev nrawm nrawm hauv qee thaj chaw, ua rau kev tsim cov npuas. Qhov no tuaj yeem tshwm sim los ntawm kev tsis xwm yeem ntws ntawm cov qauv electrolyte, lossis tsis sib xws xa tawm tam sim no;
(6) Tsis tsim nyog sib piv ntawm anode thiab cathode: thaum lub sij hawm lub tshuab hluav taws xob, qhov sib piv thiab thaj tsam ntawm anode thiab canrode yuav tsum tsim nyog. Yog hais tias tus piv ntawm anode rau cathode tsis tsim nyog, piv txwv li, yog qhov ceev ceev dhau, qhov tam sim no yuav ua rau muaj kev ua npuas dej yooj yim, uas yooj yim ua rau ua npuas dej
