Lokacin kowane salula kuma yana buƙatar saita yadda ya dace, kamar tazara tsakanin zafin jiki zuwa ƙarancin zafin jiki.

Samfurin samfurin gwaji: an sanya samfurin PCBA a cikin matsayin da aka ƙayyade a cikin yanayin gwajin Thermal na gaba don tabbatar da canje-canje na yanayi da kuma guje wa tsangwama juna tsakanin samfurori.

Kimantawa sakamakon gwajin gwaji

Ana kammala dubawa gani: Bayan an kammala gwajin shunin Thereral, gani na gani na PCBAa ana yin farko. Nemi bayyananne lalacewar jiki kamar hadewar jiki, haduwa da soja ya fadi, da kuma katuwar kwamiti.

Gwajin Gwajin lantarki: Yi amfani da kayan aikin gwajin kwararru, kamar multipeter, oscillscope, da sauransu, don gwada aikin lantarki na PCBA. Bincika ko ana iya aiwatar da da'ira, kuma ana iya sarrafa su ko sigogi na lantarki na kowane bangaren har yanzu suna cikin kewayon ƙwararru. Misali, ana iya samar da layin samar da wutar lantarki, ko akwai alamar raɗawa a layin watsa alashi, sabili da haka.

A wata kalma, gwajin rawar jiki Thermal yana da matukar muhimmanci don tabbatar da ingancin da amincin samfuran PcBA. Ta hanyar kwaikwayon matsanancin zafin jiki, lahani na yiwu a cikin ƙirar samfuri, zaɓi zaɓi na zamani da za'a iya inganta shi da ingantawa kafin a yi amfani da samfurin.
