Me yasa yake da wahala a yi tin a cikin pads na PCB?

Dalili na farko:Ya kamata mu yi tunanin ko matsala ce ta abokin ciniki.Wajibi ne a bincika ko akwai yanayin haɗi tsakanin kushin da takardar jan karfe, wanda zai haifar da rashin isasshen dumama na kushin.

Dalili na biyu :Ko matsala ce ta abokin ciniki.Idan hanyar walda ba daidai ba ne, zai shafi rashin isasshen wutar lantarki, zafin jiki da lokacin hulɗa, wanda zai sa ya yi wahala yin tin.

Dalili na uku: ajiya mara kyau.

① A karkashin al'ada yanayi, tin spraying surface za a gaba daya oxidized ko ma ya fi guntu a cikin kamar mako guda.

② OSP saman jiyya tsari za a iya adana don kimanin watanni 3.

③ Ajiye farantin zinare na dogon lokaci.

Dalili na hudu: sauye-sauye.

① Ayyukan bai isa ba don cire gaba ɗaya abubuwan oxidizing naPCB padko SMD matsayin walda.

② Adadin manna siyar da aka yi a haɗin haɗin gwiwa bai isa ba, kuma kayan jika na juyewar da ke cikin ƙwanƙolin solder ba shi da kyau.

③ Gilashin da ke kan wasu gidajen abinci bai cika ba, kuma mai yuwuwa ba za a gauraya ruwan da foda ba kafin amfani.

Dalili na biyar: pcb factory.

Akwai abubuwa masu mai a jikin kushin da ba a cire su ba, kuma ba a yi oxidized surface na pad kafin barin masana'anta.

Dalili na shida: reflow soldering.

Tsawon lokacin preheating ko yawan zafin jiki mai zafi yana haifar da gazawar ayyukan juyi.Yanayin zafi ya yi ƙasa sosai, ko gudun ya yi sauri, kuma tin ɗin bai narke ba.

Akwai dalilin da ya sa kushin solder na allon kewayawa ba shi da sauƙin yin tin.Lokacin da aka gano cewa ba shi da sauƙi a yi tin, ya zama dole a duba matsalar cikin lokaci.
