Apr 17, 2020
& nbsp; & nbsp; & nbsp; We all know that in the process of PCBA production, the requirements for the production environment are very high, but the requirements for the storage of PCBA boards are also very high. Because after PCBA processing is completed, if the product is not assembled in time, then PCBA needs to be stored to prevent PCBA from being exposed to the air for a long time and affecting the performance of PCBA.
& nbsp; & nbsp; & nbsp; Let me introduce the main conditions of PCBA storage:
1 three Uch {anti - bo'yoqni qo'llang
& nbsp; & nbsp; & nbsp; Uzoq vaqt davomida ishlatilmaydigan PCBA taxtalari uchun namlikka, changga va oksidlanishga qarshi ta'sirga ega, PCBA saqlash vaqtini samarali ravishda uzaytirishi mumkin bo'lgan uchta - bo'yoq bilan qoplangan bo'lishi kerak.
2、Vacuum packaging
& nbsp; & nbsp; & nbsp; PCBA ombori havo va suv bilan aloqa qilmaydi. Birinchidan, PCBA taxtasini o'rash uchun vakuum sumkasidan foydalaning va qadoqlash paytida qabariq plyonkani o'rash kerak. Pufakchali plyonkaning suvga singishi yaxshiroq, bu namlikka chidamlilikda yaxshi rol o'ynaydi. Albatta, namlik - dan kam bo'lmagan kam bo'lishi mumkin. Keyin tasniflangan chiqindilarga etiketkalarni yopishtiring. Yopishtirilgandan so'ng, quti quruq va havalandırılan joyda, devor va zaminning tashqarisida saqlanishi kerak va uni quyosh nurlaridan himoya qilish kerak.
3、Control the temperature and humidity of the warehouse
& nbsp; & nbsp; & nbsp; When PCBA is stored in the warehouse, the temperature of the warehouse should be controlled at 23 ± 3 ℃, 55 ± 10% RH. The storage conditions should be less than 25 ° C, relative humidity less than 65%, with temperature control, and no corrosive indoor environment gas.
