We haven't run a profile yet....probably because we're a-feared to. We can't do topside preheating here to any degree because we use an aluminum plate for aligning hundreds of top side through-hole components (pots, switches, buttons, LEDs) that te

It depends on your product requirements. We don't like to print off-pad, because: * Tough to control the amount of paste that squirts onto the board, because the aperture is not gasketed to the pad on the board. * Some paste that squirts between the

We fired an operator because he used to initial a whole sheet of reel change tracking sheet at the start of his shift "to save time!" Some people just don't get the picture. A whole reel of resistors (20,000) went through because he did not bother to
