11. Kev Paub Txog Tsis Siv Neeg SMD LED Teeb Kho Tshuab

Yuav txo cov suab nrov li cas ntawm lub Rooj Tswjhwm Saib

Ntau tus neeg tsim hluav taws xob hluav taws xob feem ntau ua haujlwm zoo tshaj plaws hauv kev tsim hluav taws xob, tab sis thaum lub sij hawm debugging, muaj ib txwm muaj ntau yam tsis muaj suab nrov. Thaum kev soj ntsuam ze, qhov chaw ntawm qhov teeb meem tsis meej, tsis muaj kev xaiv tab sis rov tsim lub rooj tsavxwm. Tau ntsib nrog lub suab nrov, Lianxinghua tau txheeb xyuas cov hauv qab no los txo nws.

Feem ntau, lub Circuit Court yuav tsum tau muab faib los ntawm cov modules, nrog rau thaj chaw nyob ntsiag to ntawm kev sib faib kom txo tau qhov cuam tshuam ntawm lub zog hluav taws xob thiab hauv av ntawm lub teeb liab, yog li txo cov suab nrov hauv Circuit Court. Cov txheej txheem tshwj xeeb yuav raug tshuaj xyuas thiab daws ua ke hauv qab no.

Rau lub rooj tsavxwm ua tau zoo, cov txheej txheem dav dav pom meej meej thaum xub thawj siab ib muag (xav tias ib tug nkag siab txog kev ua haujlwm ntawm lub rooj tsavxwm). Qhov no yog qhov peb feem ntau xa mus rau lub hauv paus ntsiab lus ntawm kev ua haujlwm module sib cais. Lub functional module yog ib phau ntawm circuits uas cov khoom siv hluav taws xob ua ke los ua ib qho haujlwm tshwj xeeb. Hauv kev tsim qauv tiag tiag, peb yuav tsum tso cov khoom sib txuas ua ke, ua kom luv luv ntawm kev sib txuas ntawm lawv los txhim kho cov haujlwm ntawm lub module. Lub tswv yim no yooj yim to taub, thiab peb feem ntau pom nws nyob rau hauv kev loj hlob boards los yog mobile xov tooj, tshwj xeeb tshaj yog nyob rau hauv cov xov tooj. Yog tias koj disassemble ib lub xov tooj, koj yuav pom qhov pom kev sib cais ntawm cov modules, thiab txhua lub module yog thaiv los ntawm Faraday tawb.

Qhov thib ob, thaum ob qho tib si analog thiab digital circuits muaj nyob ntawm PCB, lawv yuav tsum tau muab cais tawm. Ib cheeb tsam nyob ntsiag to yuav tsum tau tsim, uas lub cev cais cov analog thiab digital circuits lossis lwm yam kev ua haujlwm. Qhov no tiv thaiv kev cuam tshuam ntawm cov modules sib txawv. Nyob rau hauv lub xov tooj ntawm tes Circuit Court board hais ua ntej, qhov chaw nyob ntsiag to yog meej. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaj chaw nyob ntsiag to tsis txuas nrog lub rooj tsav xwm hauv av.

Hauv kev tsim qauv tsim hluav taws xob, tsis yog txhua lub PCB boards muaj qhov chaw txaus rau thaj chaw nyob ntsiag to. Yog li, thaum qhov chaw txwv, nws yuav tsum tsim li cas? Kuv tau sau cov ntsiab lus hauv qab no:

A. Siv lub tshuab hloov pauv lossis cov teeb liab cais tawm. Qhov no txhais tau hais tias sib cais circuits, ib qho kev sib txuas nrog cov khoom xws li CMOS lossis transistors.

B. Hla lub teeb liab los ntawm lub lim dej ua ntej nws nkag mus rau hauv lub module. Qhov no yog ib txoj hauv kev los tiv thaiv ESD (Electrostatic Discharge), thiab nws tseem tuaj yeem pab tshem tawm suab nrov (xws li ESD, high-frequency, thiab high-voltage suab nrov).

C. Siv hom hom inductor rau kev tiv thaiv teeb liab. Txawm hais tias qee tus yuav nug txog tus nqi ntawm cov khoom siv no, tshwj xeeb tshaj yog thaum tsuas yog ob lub coils tshwm sim ntawm schematic, hom hom inductor ua lub luag haujlwm tseem ceeb hauv kev ruaj khov ntawm cov teeb liab thiab txo cov suab nrov cuam tshuam.
