Dave, By Mishandled OSP i meant that it had been touched by bare hands (including pads). Its not like I want to or I donot want to bake these boards. Its just that i want to be sure that the boards will be good to use. And I like your idea to apply

Sr. Assuming you are processing the garden variety 63/37 paste on FR4 substrates, a good starting point is to plan for 3.5 to 4.5 minutes of process time on the board. If you measure the total heated length of your oven and you use the range above,
