Aluminum board process-C

5.9.2 precautions:
A.by board member of the board must pay attention to check, for no good grinding can take to mill again, for chafed can pick out those with sand paper (2000 #), sand flat after grinding plate.    
B. in a discontinuous production condition, must strengthen the maintenance, to ensure clean, tank cleaning.   
5.9.3 must be confirmed by the captain after Aluminum circuiy board surface has been handle, can only flow down.   
5.10 impact
5.10.1 edge with both hands, pay attention to the aluminum surface protection.    
5.10.2 aluminum plate forming die adopts high-grade beer board, and punching and shape a rushed or separate, impact, in accordance with the requirements of the MI must be placed after a piece of white paper on the surface of the aluminum plate.
5.10.3 impact should strengthen the inspection, pay attention to the don't fall green oil and chafed board face.   
5.10.4 no washing board at the time of the final inspection, the board, board with board between every good white skin.
5.10.5 every flush plate factory mold with a brush to clean again. 
5.11 final inspection: according to the IPC comprehensive enterprise standard and so on for each test.   

5.12 the packing  
5.12.1 different period, different packaging material number plate should be classification.    
5.12.2 when packing, please put moistureproof paper insulation and bead, and in the smallest package labels model indicating the version number, after the production cycle () a month for a cycle, etc.
6. About the final inspection chafed, oxidation of aluminum board's final inspection rework method caused by in the process of production of oxidation and flower aluminum plate, rework processing as follows.    
6.1 aluminum surface oxidation of aluminum plate: first line up the aluminum plate and emissions in the desktop, the cover line with welan and compaction, and then a few welan with double-sided adhesive, with a piece of light copper stick on it, the same to compaction, and then you can get a deburring machine on grinding plate.Note that before the grinding plate must turn off the pickling and put this section of the road wheel with tap water rinse clean to prevent pollution of acid tin, or directly from pickling after washing section into the aluminum base face up, only to open the above grinding brush, after grinding plate, such as oxidation phenomenon, can be ground again.Good grinding plate monolithic monolithic, put in grinding machine drying on the drying period, place 5 ~ 10 min, also can be put on the tray in white paper, take to the oven drying, 100 ℃ by 5 ~ 10 min, be careful not to take to forming washing machine to dry, because of its low temperature, it will bring aluminum surface oxidation.  

6.2 aluminum surface brush flower aluminum plate:
6.2.1 aluminum surface slightly brush flower aluminum plate, according to the aluminum surface oxidation 6.1 rework method.
6.2.2 aluminum face serious chafed aluminum board, first of all, use 2000 # sandpaper will wipe brush flat take place, and then use 4000 # sandpaper gently brush again, then 6.2.1 aluminum surface oxidation of aluminum plate rework method for processing.
