Qeexitaan

PCBARED PCBA (Golaha Guddiga ee Daabacaadda PCEFURE) Imtixaanka Toomka Ther-ka waa tijaabada isku halaynta. Waxaa inta badan loo isticmaalaa in lagu qiimeeyo dulqaadka PCB ee deegaanka isbedelka heerkulka deg-degga ah.

Ujeedada imtixaanka

Hubso isku haleeya isku haleeya isku haleeya Jaangooyooyinka kuleylka ayaa sababi kara wadajirka iibiyaha si loo mariyo geedi socodka ballaarinta iyo foosha. Imtixaanka naxdinta leh ee kuleylka, waxaa suurtagal ah in la arko in wadajirka gacanta uu dillaaco, dabacsan oo dhibaatooyinka kale ee hoos yimaada isbeddelka noocaas ah ee heerkulka. Tusaale ahaan, PCBA ee qaar ka mid ah alaabada elektiroonigga ah ee macaamiisha, sida motteroboard-ka taleefanka gacanta, haddii tayada wadajirka gacanta aan la aqbali karin, wareegga wareegga ayaa laga yaabaa in shoog kuleylka ah ka dib, taasoo dhalisay guuldaradii qaar ka mid ah howsha moobiilka .

Qiimaynta isbeddelada waxqabadka ee maadooyinka: Waxqabadka qaybaha elektiroonigga ah ayaa laga yaabaa inay saameyn karto marka heerkulku is beddelo. Tusaale ahaan, qiimaha kartida ee daadadku wuxuu ku beddeli karaa isbeddel fiiqan heerkulka. Tijaabada naxdinta leh ee kuleylka ayaa kaa caawin karta go'aaminta in qaybahaani ay si sax ah ugu shaqeyn karaan jawiga isbeddelka heerkulka ee heerkulka ah iyo in kala-duwanaanta waxqabadka ay ku jirto xadka la oggol yahay.

Hubi is-waafajinta maaddada: PCBA waxay ka kooban tahay qalab kala duwan, oo ay ku jiraan agabyada guddiga wareegga, agabyada baakadaha elektiroonigga ah, iwm. iyo dillaac. Tijaabada naxdinta leh ee kuleylka ayaa hubin kara is-waafajinta udhaxeysa agabkan.

Nidaamka imtixaanka

Shuruudaha Qalabka: Qolka imtixaanka naxdinta leh ee kuleylka waxaa badanaa loo isticmaalaa baaritaanka. Qolka imtixaanka ayaa si dhakhso leh u beddela kara heerkulka sare iyo kan hoose, wuxuuna si sax ah u xakamayn karaa heerka iyo heerkulka isbedelka heerkulka.

Tijaabada Tijaabada Ogaadda: oo ay ku jiraan dejinta qiimaha heerkulka sare, qiimaha heerkulka hooseeya iyo tirada wareegga heerkulka. Guud ahaan, heerkulka sare waxaa loo dejin karaa ilaa 125 ° C, oo heerkulka hoose ayaa loo dejin karaa -40 ° C. Tirada wareegga ayaa laga yaabaa in lagu dejiyo daraasiin ama boqol jeer oo waqti ah sida ku xusan jawiga isticmaalka iyo shuruudaha sheyga. Waqtiga wareegga kastaa sidoo kale wuxuu u baahan yahay in si habboon loo dejiyo, sida waqtiga u dhexeeya heerkulka sare ilaa heerkulka hoose iyo dib ugu laabashada heerkulka sare.

Meelaynta saamiga: Muunadda PCBA waxaa lagu meeleeyaa booska la cayimay ee qolka tijaabada kuleylka si loo hubiyo inay si buuxda u saameyn karto heerkulka oo ay ka fogaadaan faragalinta labada dhinac ee muunadaha.

Qiimaynta natiijooyinka imtixaanka

Baadhitaan Muuqaal ah: Ka dib markii baaritaanka naxdinta kuleylka la dhammeeyo, kormeerka muuqaalka ee PCBA ayaa marka hore la sameeyaa. U fiirso waxyeelo muuqata muuqata sida barokacyada qaybta, galka gacanka ee soo dhacaya, iyo xakameynta guddiga wareega.

Tijaabada Waxqabadka Korantada: Adeegso qalabka tijaabada xirfadeed, sida kuwa muhiimka ah, oscilloscope, iwm, si loo tijaabiyo waxqabadka korantada ee PCBA. Hubi in wareegga si caadi ah loo fulin karo, iyo in cabirrada korantada ee ka kooban qayb kasta ay weli ku jiraan tirada u qalma. Tusaale ahaan, in khadka korantada ee wali la bixin karo sida caadiga ah, haddii ay jirto dhalanro is-afgaradka oo ku yaal khadka gudbinta calaamadda, iyo wixii la mid ah.

Erey, baaritaanka naxdinta leh ee PCBA waa mid muhiimad weyn u leh in la hubiyo tayada iyo isku halaynta waxyaabaha PCBA PCBA. Adigoo muujinaya jawiga is-beddelka heerkulka ee heerkulka ah, ciladaha suurtogalka ah ee naqshada sheyga, xulashada sheyga ama nidaamka wax soo saarka ayaa laga heli karaa hormaris, si loo wanaajiyo ka hor inta aan si rasmi ah loo adeegsan. Tani waxay gacan ka geysaneysaa yareynta heerka fashilka ee sheyga habka loo isticmaalo dhabta ah, wanaajinta xasilloonida iyo nolosha adeegga ee sheyga, iyo kor u qaadista tartanka badeecada suuqa. Haddii elektiroonigga korantada, aaladda xakamaynta warshadaha ama elektiroonigga baabuurta iyo meelaha kale ee loo yaqaan 'pasba', tijaabada naxdinta leh ee PCBA waa mid ka mid ah xiriiriyeyaasha saxda ah ee nidaamka elektiroonigga ah, oo aasaas u ah hawlgal adag Qalabka elektiroonigga ah.
