1.The olubi ukufuma amacandelo-elektronikhi kunye umatshini yonke
Uninzi iimveliso elektroniki zifuna yokusebenza kunye nokugcinwa phantsi conditions.According owomileyo manani, ngaphezu kwekota woveliso mveliso iimveliso ezimbi zehlabathi zinxulumene ukuba dampness.For ishishini ngekhompyutha, ngamathontsi umonakalo ibe ngomnye wemiba ephambili echaphazela umgangatho ngeemveliso.
(1) Integrated eshicilelweyo ibhodi yesekethe: ngamathontsi ukufuma kushishino semiconductor i kakhulu wabonakaliswa ukufuma eza kusichukumisa kwi IC embindini nge IC zeplastiki zokubopha ukusuka izikhonkwane kunye nezinye izithuba, ukuvelisa IC ukufuma Ukunciphisa nesenzeko.
Umphunga wamanzi luyakha ngexesha lenkqubo ubushushu iSMT pcb inkqubo assmblling, ukudala uxinzelelo ebangela i-IC nentlaka iphakheji ukuqhekeza kwaye oxidize intsimbi ngaphakathi isixhobo IC, leyo ukusilela kwimveliso. Ukongeza, xa ifowuni kwi ibhodi PCB inkqubo welding, ngenxa kokukhutshwa uxinzelelo umphunga wamanzi, kuya kukhokelela Weld.
Ngokusekelwe kwi-IPC - M190 J - STD - 033 ibhanile, ekubeni ilandelayo umoya kunye nokusingqongileyo lokufuma kweekhomponenti SMD, kuyimfuneko ukuba uyibeke phantsi-10% RH ixesha exposure ukufuma bunikwa eziko amaxesha-10 ngexesha, "workshop" ubomi i element kukuba ukubuyela ukuphepha ezilahliweyo, ukuqinisekisa ukhuseleko.
(2) icebo LCD: izixhobo LCD screen LCD efana negilasi kunye polaroid, nangona icebo lokucoca kwinkqubo imveliso nokucoca omiswe, kodwa emva lungapholi yayo ziya kuchaphazeleka ukufuma, ukunciphisa ekhulwini lokupasa le products.Therefore, kufuneka igcinwe kwindawo eyomileyo ngaphantsi 40% RH emva zokucoca omisa.
(3) amanye amacandelo elektroniki: capacitors, izakhi yodongwe, izihlanganisi, itshintshela, ngelotha, PCB, ngumkhenkce, lesilicon, zwi oscillator, SMT iglu yokuncamathelisa, izixhobo electrode, unama-elektroniki, izixhobo phezulu ukukhanya, njalo njalo, bonke baya kuchatshazelwa yi umanzi umonakalo.
(4) izixhobo zombane kwinkqubo ukusebenza: iimveliso semi-ogqityiweyo ezisebhokisini ukuya inkqubo elandelayo; PCB ukuphakheja phambi nasemva encapsulation ukudibanisa; I-IC, BGA kunye PCB ezingakhange zisetyenziswe emva kokuba ibattery; Ukulinda ukuba isixhobo ngelotha, le fowuni ukuba ukulungele zibuyiselwe lobushushu emva baking; ziyadakancwa wagqiba iimveliso, njl, iza kuchatshazelwa yi ngamathontsi.
(5) i-kweemveliso ezigqityiweyo ziya yayonakaliswe ukufuma ngexesha kubekwa process.If ixesha ukugcinwa kakhulu elide ukufuma eziphakamileyo, oko kuya kubangela ukuba ukusilela ukwenzeka, kwaye cpus ibhodi computer kuya kubangela ngomnwe igolide igcwala ukuba isizathu ukungaphumeleli contact.
Ukwenziwa kweemveliso mveliso elektroniki kunye nendawo yokugcina le mveliso kufuneka ibe ngaphantsi kwe-40% .Abanye iintlobo nazo zifuna ukufuma ngaphantsi.
KingSong Technology njenge mnye-ukumisa iNdibano PCB nomakhi , uye ulawulo olungqongqo malunga nezinto zikagesi, ukuze kuqinisekiswe impumelelo yayo, njengoko ukuze ukunika abathengi bethu quality.if ezilungileyo unayo nayiphi na iprojekthi PCBA, Wamkelekile ukuba uqhagamshelane nathi ngokukhululekileyo, ndiyabulela!
