Idaacadda kabida gacmahoodii

Inta lagu guda jiro dib u samaynta, chip, motherboard, computer waa lagama maarmaan in la isticmaalo bir ah, kabida. Laakiin waxaa had iyo jeer ma aha habboon in la isticmaalo, maxaa yeelay waxa ay si deg deg ah overheats, ma jiro wax fursad si ay ula qabsadaan heerkulka. Ka dibna waxaad u baahan tahay saldhigga a mobile sare Rework. gacmihiisa iyada ku wareegsan barteen si ay u abuuraan saanacyadii.

Mid ka mid ah doorasho - abuuro xarun kabida, in la dhigayaa in korontada (more hufan, oo ay jirka) by kabida, on size ee siddeetan iyo konton iyo shan iyo lixdan iyo shan milimitir, oo waxaa ku xiran darina EPSN jir. In la abuuro saldhigga Laxaamaddu ayaa loo baahan yahay si ay u bartaan iska caabin ah ay u kabida, shidma resistive kululeeyaha iyo Micida waslad dheeraad ah 1.6 milimitir.

In EPSN gundhig multimeter thermocouple ka Shiinaha. guddiga dirato ka heli karto xajmiga iyo saddex iyo afartan inay saddex iyo soddon milimitir. digital qaadan karo saldhigga, kabida, waxay gacmahooda ku soo ururay, ayaa sheegay in diyaar u ah inay u isticmaalaan fariimihii kabida miraayadda. Ka dib markii la bilaabay xakamaysada ah waxaa ka mid ah ACC oo akhriya gashiga ee PC0, heerka danab PC1. Haddii ay sidaa tahay, haddii ay tahay si siman u danab sahayda, si kabida lahayn, oo ku qorraa «qalda», qaladka lagu soo waramayaa bandhigo.

Marka danab ee mid ka mid ah gashiga ay ka yar tahay 4.5 volts, ka dibna waxaa suurtagal ah inay doortaan birta, kabida ama resistive ama thermocouple ah. Waxaa intaa dheer, mid kasta isticmaali kartaa badhannada si ay ula qabsadaan heerkulka. bandhigay waxay muujinaysaa dhibic ka bilig in sheegayaa taas oo ka mid ah qalabka waa la soo xulay. bir Power kabida la kaantarooli karaa by isbedbeddelka PWM VT1 muhiimka ah.

Marka socday saldhigga kabida, gacmahooda, oo aad samayn karto oo aan ka transistors dheeraad ah, sababtoo ah hadda ka mid ah 2 MA waa la helay iftiin aad u daran oo dhalaalaysa. Cathodes toos ah ugu xiran dekedaha dirato. fiilooyin khafiif LED u baahan tahay inaad Alxan guddiga iyo hagaajin dhinaca danbe taasi oo ka koolo dhalaalisa kulul.

Si aad meel badhamada iyo qaab ay u baahan yihiin si ay u sameeyaan godad in guddi hore. Murayaad Jaantuska in image muraayad ku daabacan film hufan, cajalad, Jinka-madaxyo simanna cad koolo ka hannaankii toner baabbi'in hareeraha wareega dibna negaanaya guryaha. Wixii habboonaan ee badhannada waa ka wanaagsan inuu ku soo shirtagi in guddi habka koolo dhalaalisa kulul.

Waayo, shaqada rakibo, lacag dheeraad ah, sida motherboard ama laptop PC, ku haboon saldhigga kabida infrared, gacmo iyaga u gaar ah si ay u sameeyaan, sidoo kale, waa arrin dhab ah. Waayo, kabida, dusha-dhajinta guddiga circuit ku daabacan iyo qaybaha (tus, BGA) haboon labada hawada kulul ama shucaaca infrared.

Qalabka wuxuu ka kooban yahay qaybta gacanta ah, oo ku yaalla guryaha gaar ah. Waxay leedahay laba kululeeyayaasha iyo kulamada guddiyada. jagada sare waa la bedeli karaa iyadoo ku xiran lacag go'an. kululeeyaha hoose waxay bixisaa element kulaylka for koronto awood kilowatts laba iyo ballaciisu yahay laba boqol iyo labaatan milimitir. kululeeyaha Sare - afar laambadihii halogeen embriyaha. Mid kasta oo iyaga ka mid ah - 150 watts. Sayidka, saldhigga Laxaamaddu, waxay gacmahooda ku soo ururay, ayaa noqonaya eegno dhammaadeen.

Maala A waxaa la samayn karaa ka strips of printer furta. Inta kale ee faahfaahin ah - sidoo kale laga soo amaahday qalabka computer jir. Tusiyaha adeegta laba-line module crystal dareere iyo xakamaysada ah. Halkii gudbiyeyaasha garaaca wadnaha fiican in la isticmaalo semistors iyo hiitarka. Waa in la xusuusnaado in ay usoo noolaatay ay rakibaadda u baahan yahay taxadir sida semistors. Waxa intaa dheer in kuwan qaybood ayaa lagama maarmaan ah looga baahan yahay korontada saldhigga kabida, in waxa uu siiyaa hadda laba channels, keyboard ah, bandhig, qaylo-dhaanta iyo eber.

Haddii aad abuuray saldhigga kabida, gacmahooda, iyo waxa muhiim ah in la ogaado qaar ka mid ah xeerarka at iyada badbaadada shaqada. Tusaale ahaan, waxaan Ma ogolaan karo laambadihii halogeen ayaa wasakheeyey dufan. Sidaa darteed, waa in si taxadir leh loo nadiifiyaa acetone ama baasiin, iyo ka hor inta aanad bilaabin inay xirtaan muraayadaha ilaaliya.
