Green vs Blue Soldermask | 3 September, 1998

Can any one tell me if there is a large difference between green soldermask and blue soldermask, in reference to sending the board through the IR reflow oven. - two PCB's (smc parts) are manufactured, the first has green soldermask, the second blue soldermask. - how much of a change is need to the IR oven settings between the two boards, if any?

None, provided you are not using a "true" IR oven or the solder mask types are the same but for color. Earl Moon
