Amacandelo e-elektroniki awona macandelo aphambili kwi-chip processing, amanye amacandelo kunye neentlobo ezahlukeneyo eziqhelekileyo, adinga ukugcinwa okukhethekileyo ukuqinisekisa ukuba akukho ngxaki, ubushushu kunye nokufuma kwezinto ezinovakalelo yenye yazo.Ubushushu kunye nokufuma amacandelo abuthathaka ulawulo ugcino kwinkqubo processing zibaluleke ngakumbi, kuya kuchaphazela ngqo umgangatho PCBA processing.Ekuqinisekiseni ukusetyenzwa kwe-smt SMD xa ukusetyenziswa okuchanekileyo kweqondo lokushisa kunye nokufuma kumacandelo abuthathaka, ukuthintela amacandelo ngokufuma kokusingqongileyo, ukufuma kunye nokusetyenziswa kwezinto zokupakisha ezichasene ne-static, ezi ngongoma zilandelayo zinokulawula ulawulo olusebenzayo, ukuphepha ukulawulwa ngokungafanelekanga kwezinto. kunye nokuchaphazela umgangatho.
Ezi ndlela zintathu zilandelayo zolawulo ukusuka kokulandelayo ukuhlalutya oku kulandelayo
Ulawulo lwendalo esingqongileyo
Ulawulo lwenkqubo
Umjikelo wokugcina icandelo
I. Ulawulo lwemo engqongileyo (indawo yokugcina ivalela ukufuma kweemeko zokusingqongileyo)
Umzi-mveliso wokusetyenzwa kwe-PCBA ngokubanzi uya kuphuhlisa inkqubo yolawulo lobushushu kunye nokufuma kwezinto ezinovakalelo, iqondo lobushushu lendawo yokusebenzela kufuneka ilawulwe kwi-18 ℃ -28 ℃.Kwindawo yokugcina, iqondo lokushisa kufuneka lilawulwe kwi-18℃-28℃ kunye nokufuma okuhambelanayo ngaphantsi kwe-10%.Ukuze kugcinwe indawo yokushisa kunye nomswakama kwindawo evaliweyo yefektri, indawo akufanele ishiywe ivulekile okanye ivule ngaphezu kwemizuzu emi-5.
Abasebenzi bezinto eziphathekayo rhoqo kwiiyure ezi-4 ukujonga ubushushu bebhokisi yobungqina bomswakama kunye nomswakama, kunye nexabiso layo lokushisa kunye nomswakama obhaliswe "kwitafile yokulawula ubushushu kunye nomswakama";ukuba iqondo lokushisa kunye nomswakama udlula uluhlu oluchaziweyo, ngokukhawuleza wazise abasebenzi abachaphazelekayo ukuba baphucule, ngelixa uthatha amanyathelo afanelekileyo okulungisa (njengokubeka i-desiccant, ukulungelelanisa ubushushu begumbi okanye ukususa amacandelo kwibhokisi ephosakeleyo yobungqina bomswakama, kwi-humidity efanelekayo- ibhokisi yobungqina)
II.Ulawulo lwenkqubo (iindlela zokugcina amacandelo achaphazeleka kukufuma)
1. Ukuthintela umonakalo kwizinto ezibangelwa ngumbane ongaguqukiyo, ekudilizweni kwepakethe ye-vacuum ye-humidity-sensitive components, umqhubi kufuneka aqale anxibe iiglavu ezimileyo, i-static hand ring, emva koko avule i-vacuum packaging kwi-desktop ekhuselwe kakuhle kwi-static. umbane.Jonga ukuba iqondo lobushushu kunye nokufuma kwekhadi utshintsho lwamacandelo ayahlangabezana neemfuno, kwaye amacandelo ahlangabezana neemfuno anokufakwa iilebhile.
2. Ukuba ufumana amacandelo e-bulk humidity-sensitive, yiba ngowokuqala ukuqinisekisa ukuba amacandelo afanelekile na.
3. Khangela ukuba isikhwama sokukhusela ukufuma kufuneka sikhatshwe yi-desiccant, ikhadi lokufuma elihambelanayo, njl.
4. Amacandelo anovakalelo lokufuma (IC) emva kokukhulula i-vacuum, ukubuyisela kwi-solder ngaphambi kokuba ixesha lokuvezwa emoyeni aliyi kudlula ibakala kunye nobomi obubuthathaka bokufuma, kufuneka ngokungqongqo ngokungqinelana nemigangatho ehambelanayo yeplanti ye-PCBA. sebenza.
5. ukugcinwa kwamacandelo angavulwanga kufuneka agcinwe ngokweemfuno, kuba amacandelo avuliweyo kufuneka abhakwe kwaye afakwe kwiingxowa ezinobungqina bokufuma kunye ne-vacuum etywinwe ngaphambi kokuba igcinwe.
6. Kumacandelo angafanelekanga, uwanike abasebenzi bokulawula umgangatho ukuba babuyele kwindawo yokugcina impahla.
III.Ixesha lokugcina lamacandelo
Akukho ngaphezu kweminyaka emi-2 ukususela kumhla wokuveliswa ngumenzi wecandelo ngenjongo yoluhlu lwempahla.
Emva kokuthenga, ixesha le-inventri yomsebenzisi wefektri ngokubanzi alidluli unyaka we-1: Ukuba indawo yendalo ingumzi mveliso womatshini omanzi, emva kokuthengwa kwamacandelo adityaniswe phezulu, kufuneka asetyenziswe kwiinyanga ezi-3, kwaye i-humidification efanelekileyo - kufuneka ithathwe. kwindawo yokugcina kunye nokupakishwa kwecandelo ukubonisa imilinganiselo.
