hi Mr.Pentu
you may try to upload again..maybe the server is busy or the line is going down when you upload it,,never mind pls try again...
anyway last night i was trying to clean another acer aspire 4520 bga pads for reball, as usual i put a little flux first, then set solder tip for about 350-400 C to swipe all solder balls on pad slowly,.after that i use "BAKKU" solder wick to clean the lefted solder balls carefully on pad,,
i used to clean it from right side to left for whole pads, until now i still hv a problem to fix it well, i can see some pads will be lefted ( take off by solder wick ) when i cleaned it, i hv run it slowly and carefully but some pads still going to lefted,,
all i want to know is..am i using a wrong solder wick or having a wrong direction to clean the pads?any tips for this pls guide me to the right way for doing this better as i hv tried for more than 10pcs of bga pad on boards and all with fails...
thank you...
