ʻAʻole mālama ʻia ka "Hoʻomaʻemaʻe" i ke kaʻina hana PCBA o nā papa kaapuni, a manaʻo ʻia ʻaʻole he hana koʻikoʻi ka hoʻomaʻemaʻe.Eia nō naʻe, me ka hoʻohana lōʻihi o ka huahana ma ka ʻaoʻao o ka mea kūʻai aku, ʻo nā pilikia i hana ʻia e ka hoʻomaʻemaʻe pono ʻole i ka wā mua ke kumu nui o nā hemahema, hoʻoponopono a ʻO nā huahana i hoʻomanaʻo ʻia ua hoʻonui nui i nā kumukūʻai hana.Ma lalo iho, e wehewehe pōkole ʻo Heming Technology i ke kuleana o ka hoʻomaʻemaʻe PCBA o nā papa kaapuni.

ʻO ke kaʻina hana o ka PCBA (paʻi kaapuni hui) hele ma nā kaʻina hana he nui, a ua haumia kēlā me kēia pae i nā degere like ʻole.No laila, waiho ʻia nā waihona like ʻole a i ʻole nā ​​​​mea haumia ma ka ʻili o ka papa kaapuni PCBA.ʻO kēia mau mea haumia e hōʻemi i ka hana o ka huahana, a hiki i ka hopena o ka huahana.No ka laʻana, i ke kaʻina hana o ka soldering electronic parts, solder paste, flux, etc. i hoʻohana ʻia no ka soldering auxiliary.Ma hope o ke kūʻai ʻana, hana ʻia nā koena.Aia i loko o ke koena nā ʻakika a me nā ion.Ma waena o lākou, e hoʻopau nā ʻakika organik i ka PCBA kaapuni.ʻO ka hiki ʻana mai o nā iona uila ke hoʻopōkole a hoʻopau i ka huahana.

Nui nā ʻano mea haumia ma ka papa kaapuni PCBA, hiki ke hōʻuluʻulu ʻia i ʻelua mau ʻāpana: ionic a me non-ionic.Ionic pollutants hele mai i loko o pili me ka makū i loko o ke kaiapuni, a electrochemical neʻe ma hope o electrification, hana i ka dendritic hale, ka hopena i ka haʻahaʻa kū'ē ala, a me ka luku ana i ka PCBA hana o ka papa kaapuni.Hiki i nā pollutants non-ionic ke komo i ka papa insulating o PC B a ulu i nā dendrites ma lalo o ka ʻili o ka PCB.Ma waho aʻe o ka ionic a me ka non-ionic pollutants, aia pū kekahi pollutants granular, e like me nā pōpō solder, nā wahi lana i ka ʻauʻau solder, lepo, lepo, a me nā mea ʻē aʻe. Hoʻokala ʻia nā hui i ka wā e kūʻai ai.Nā hanana like ʻole e like me nā pores a me nā pōkole pōkole.

Me ka nui o nā mea haumia, ʻo wai ka mea e hopohopo nui ai?Hoʻohana maʻamau ʻia ka Flux a i ʻole ka solder paste i ka hoʻoheheʻe ʻana a me nā kaʻina hoʻoheheʻe nalu.Hoʻokumu nui ʻia lākou me nā solvents, nā mea hoʻomaʻemaʻe, resins, corrosion inhibitors a me activators.Pono nā huahana i ho'ololi wela ma hope o ke kū'ai 'ana.ʻO kēia mau mea Ma ke ʻano o ka hāʻule ʻana o ka huahana, ʻo nā koena post-weld ka mea nui e pili ana i ka maikaʻi o ka huahana.ʻO nā koena Ionic ka mea e hoʻoneʻe ai i ka electromigration a hoʻemi i ke kūpaʻa insulation, a ua maʻalahi nā koena resin rosin e adsorb ʻO ka lepo a i ʻole nā ​​mea haumia e hoʻonui ai i ke kūpaʻa pili, a ma nā hihia koʻikoʻi, e alakaʻi i ka hāmama kaapuni.No laila, pono e hoʻomaʻemaʻe ʻia ka hoʻomaʻemaʻe ma hope o ka welding e hōʻoia i ka maikaʻi o ka PCBA circuit board.

I ka hōʻuluʻulu ʻana, he mea nui ka hoʻomaʻemaʻe ʻana i ka papa kaapuni PCBA.ʻO ka "hoʻomaʻemaʻe" kahi hana koʻikoʻi e pili pono ana i ka maikaʻi o ka papa kaapuni PCBA a he mea nui ia.
