Kauj ruam 1: Ua ntej siv Altium Designer los tsim daim duab kos duab thiab PCB ntawm lub voj voog
Kauj ruam 2: Sau daim duab PCB
Cov ntawv luam tawm thermal hloov tsis zoo heev vim tias tus number case cartridge ntawm lub tshuab luam ntawv tsis zoo heev, tab sis tsis muaj teeb meem, nws tuaj yeem ua rau kev hloov pauv tom ntej.
Kauj Ruam 3: Txiav tawm cov ntawv luam tawm thermal hloov khoom
Kauj ruam 4: Hloov PCB Circuit Court
CCL thiab txiav cov ntawv hloov thermal
Txiav cov tooj liab clad laminate raws li qhov loj ntawm PCB pawg thawj coj saib
Tau kawg, tooj liab clad laminate yuav tsum tau polished nrog cov ntawv xuab zeb zoo ua ntej kev hloov pauv (kom polish tawm cov oxide txheej)
Daim kab xev rau ntawm ib kawg ntawm daim ntawv hloov chaw
Cov khoom qub qub qub (PS: Ua tsaug rau omnipotent Taobao, tsuas yog koj tsis tuaj yeem xav txog nws, tab sis koj nrhiav tsis tau)
Tom qab 4 teev, nws zoo, cia nws txias thiab rhuav nws sib nrug
Yuav ua li cas thiaj ua tau zoo?
Tau kawg, yog tias koj tsis muaj lub tshuab hloov hluav taws xob, koj tuaj yeem siv hlau (*^__^*) Hee hee…
Kauj ruam 5: Sau thiab hloov lub PCB board
Txij li thaum lub tshuab luam ntawv tsis zoo heev, koj tuaj yeem siv lub cim los sau rau hauv qhov chaw uas tsis tau hloov mus zoo
Lub phaj hloov pauv O(∩_∩)O~ Tsis phem!
Kauj ruam 6: Corrosion PCB board
Tsis txhob nug kuv!Mus ncaj qha rau Taobao
Corrosion artifact (cua sov pas nrig + ntses tank aerator + yas thawv = PCB board corrosion tshuab)
Pom ib tug neeg nyob rau hauv lub lab welding 8X8X8 lub teeb cubes thaum tos kom corrosion kom tiav
Qhov lawv tsim lawv tus kheej tsuas yog xa tawm lub rooj tsavxwm los ua
Corrosion tiav
Kauj Ruam 7: Punching thiab Tinning
Siv cov ntawv xuab zeb zoo los xuab zeb tawm ntawm lub toner rau saum npoo ntawm PCB board hauv dej
Siv cov paj rwb swab siv ib txheej ntawm rosin rau ntawm PCB (dab tsi? Koj nug kuv tias rosin yog dab tsi? rosin yog kom yaj cov rosin rau hauv 70% cawv)
Qhov zoo ntawm kev siv rosin yog tias nws yog siv los ua flux thaum soldering.Lwm qhov zoo dua yog tias nws muaj kev tiv thaiv oxidation.
ua tinned
tinned tiav
Punch
Kauj ruam 8: Vuam thiab debugging
Tom qab kev debugging, kuv pom tias kom ua tiav txoj haujlwm kuv xav tau, muaj ib qho tso zis tsawg dua li rub-up resistor O(∩_∩)O~
cov khoom tiav
(PS: Lub teeb pom kev ntawm kev ua haujlwm los ntawm lub voj voog no yuav teeb lub LED ntawm lub rooj tsavxwm thaum lub teeb ncav cuag ib qho kev siv)
