Very late but here's my 2 cents. Will require a custom fixture for every flex or semi-rigid flex. Depending on panel thickness; use 2 tooling hole to fixture on one axis, other tooling holes will have pullers to ensure proper placement. Even with the

It depends on the flux type. If it's water soluble, it should be cleaned soon after reflow because OA flux remains active after reflow. If it's rosin or no-clean (low-residue), then the only concern is the longer wait time, the more difficult it will

Depending on the volume of work, it may be less costly and more efficient to have the board vendor add "breakaway" panels to the board to increase it's overall size. This would move the parts away from the edge of the rail, yet would negate the expen

Look into an odd form placer. There are a number of manufacturer's out there, but it depends on the volumes that you are looking for to determine how cost effective. Odd forms can deal with bulk etc relatively easily....Buy a machine that is tailored

You are 100% correctamundo!!!! Those units are very operator dependent. $15k for a lousey gauge R&R doesn't make me want to stand-up and salute.

Depending on the designers pad size, I generally go for 0.010" aperture with 0.010" spacing - stencil thickness 0.005". This combo with metal squeegees and the "usual suspects" of printer set up and placement details should you you hassle free.

emmanuel, John's right, as long as there is support, nothing changes. Depending on the size of the board fixtures might be a better option over support pins. Unless the pins jump out of the machine and follow it into the reflow oven, You never know!!

We engrave a kind of 'dog tag' which we attach on to the frame.It's fairly visible. You need to put it on somewhere that doesn't get in the way - depends on your equipment. You can also use it to give the operators an orientation for loading the st
