My input are: i. To solve tape not pulling back if it is due to high per is better to use more feeders to minimize this issue. ii. To slow down printing speed. Hence, has proper line balancing which minimize board idling before pick and place process

Do you have the ability to add copper thieving or otherwise balance the design? We had a customer making LED boards with a terible inbalance. Some of the boards would "smile" so badly in the oven that the leading edge touched the top. They switche

Hi, for what purpose do you need this? Is it for line-balancing and/or eliminating down-time? Are you a a contract manufacturer or oem? How many lines? What's the budget? Regards, Tom.

I think this part has terrible thermal balance. I assume in reflow process the part is bending so much that it will cause the shorts you see. I would suggest you get one of these beautiful hi temp cameras and record the reflow process. This video sho

Warp depends on: * How close the board gets to its Tg during the solder cycle (the closer you get to the Tg the worse the warp gets) * Amount of copper on each side and the balance between the two * Thickness of the board * Overall length x width * T
