What equipment do you have? As well as the comments from others, another major influencing factor can be the residual heat in your PCB carrier. It takes more heat energy to warm a cold carrier than if it is already hot from the last cycle run. This

It's what the customer wants. remember the customer is always right and that IPC is only recommended guidelines the last time I looked. I also belive IPC shows examples of PTH parts being preped and lap soldered to SMT pads so common sense says what'
