1.The umonakalo umswakama ukuba nezinto zikagesi futhi wonke umshini
imikhiqizo Iningi electronic zidinga yokusebenza isitoreji ngaphansi conditions.According elomile ukuba izibalo, ngaphezu ikota yokukhiqiza ezimbonini imikhiqizo ezimbi emhlabeni zihlobene dampness.For embonini electronic, dampness umonakalo bekugcwele eziyinhloko ezithinta izinga lemikhiqizo.
(1) integrated ephrintiwe wesifunda ibhodi: i dampness umswakama embonini Semiconductor ikakhulukazi ebonakaliswa nomswakama ukuthi ukungena IC ingaphakathi ngokusebenzisa IC plastic iphakeji kusukela izikhonkwane nezinye izikhala, esikhiqiza IC umswakama ukumuncwa mkhuba.
Umhwamuko luyakha ngesikhathi Ukushisa inqubo SMT PCB assmblling inqubo, ukudala ingcindezi edala IC resin iphakethe QHAHAZA oxidize kwensimbi ngaphakathi ocingweni IC, okuholela ukwehluleka umkhiqizo. Ngaphezu kwalokho, uma idivayisi ku PCB ibhodi Welding inqubo, ngenxa ukukhululwa umhwamuko ingcindezi, kuzoholela Weld.
Kususelwa IPC - M190 J - STD - 033 standard, ukuchayeka elandelayo emoyeni kanye nomswakama imvelo SMD izingxenye, kudingeka ukubeka ngaphansi 10% RH nomswakama ukuchayeka isikhathi isethwe kuhhavini ukuthi 10 izikhathi isikhathi, "workshop" ukuphila we isici ukubuyela ukugwema scrap, ukuqinisekisa ukuphepha.
(2) kudivayisi LCD: amadivayisi LCD screen LCD ezifana ingilazi futhi Polaroid, nakuba isihlungi e inqubo ukukhiqizwa for ekuhlanzeni omiswe, kodwa ngemva Ukupholisa yayo isazoqhubeka ehlaselwe umswakama, ukunciphisa amaphesenti pass the products.Therefore, kufanele agcinwe endaweni eyomile ngaphansi 40% RH emva ekuhlanzeni omiswe.
(3) nezinye zikagesi: capacitors, izingxenye Ceramic, nezixhumi, ukushintshwa, nokunamathisela ngomthofu, PCB, crystal, i-silicon asebenza ngebhethri oscillator, SMT glue ingcina, electrode izinto, unamathisele electronic, amadivayisi okusezingeni eliphezulu ukukhanya, njll, bonke bayokwenziwa ehlaselwe ezimanzi umonakalo.
(4) zobuchwepheshe enqubeni operation: imikhiqizo Semi-siphelile iphakethe ukuze inqubo elandelayo; PCB emaphaketheni ngaphambi nangemva encapsulation ukuxhuma; I-IC, BGA futhi PCB eziye zasetshenziswa hhayi ngemuva ukuqaqa; Sokulinda ngenxa kudivayisi nokunamathisela ngomthofu; idivayisi ukuthi ilungele ukuba ibuyele esikhungweni lokushisa emva baking; angakathululwa eseqedile imikhiqizo, njll, ngeke ehlaselwe dampness.
(5) imikhiqizo siphelile nayo izofakwa kabana umswakama ngesikhathi Warehousing process.If isikhathi isitoreji kakhulu isikhathi eside umswakama high, kuzobangela ukwehluleka kwenzeka, futhi CPUs ikhompyutha ibhodi uzobangela namachibi igolide umunwe imbangela ukwehluleka lokuxhumana.
I ukukhiqizwa kwemikhiqizo ngogesi ezimbonini kanye isitoreji imvelo imikhiqizo kufanele kube ngezansi 40% .Abanye izinhlobo idinga umswakama kancane.
KingSong Ubuchwepheshe njengoba omunye-stop PCB Umkhiqizi Assembly , unegunya esiqinile ngoba zikagesi, ukuqinisekisa ukusebenza yayo, njengoba kunjalo ukunikeza amakhasimende ethu nge quality.if ezinhle uneminye iphrojekthi PCBA, ukwamukela uxhumane nathi ngokukhululekile, ngiyabonga!
