Hi, Prakash. Properly conducted on appropriate substrates, both processes exhibit plenty of bond strength for virtually any application. If you are having problems with bond strength it is almost surely a problem in your process, such as inadequate cleaning or failure to remove scale, rather than a weakness in the selected technology. Further, you're generally not free to simply substitute one process for the other anyway since there are many potential limitations to each process.

Please explain your situation. Casting the question in an abstract way makes it difficult for to help you. Thanks!
