br use liquid flux to solve this problem this will give the ic flows[when rehot it allows correct automatically place the ic& also withstands the heat]

I have been changing kepad and other light ics since 2005 even now Idint face sucha problem some tims brother u may not have fixed the IC s properly while fixing these kind of Ic dont use that much air and heat as we do in the case of normal bgas after fixing clean the area properly with propalyneand dry it.If it happens only to a particular set it may be a problem related with its cpu or do one thing remove the legs of the new ic and reball it this worked many timesor fix it withoutlegs pressing it all the best...........dont overheat the cpu

Use Amtech Original Flux (paste) Your Problem Will Be Solved. I Also Faced The Same Problem Few Months Ago But After Using The Paste There Is No Problem.

keep the heat low and use injection flux available now days
