We definately look forward to having you with us. Ideally, all of the toner would leave the paper and fuse to the circuit board, and would do so without running, smearing, or flaking. DON'T slide the iron over. The reason I say crappy is you won't get plated holes, finish over the bare copper, solder mask, or silk screen. Heating the circuit board to the correct temperature and then pressing the transfer image onto it would be the ideal, especially if the act of pressing the image on reduced the temperature by a few degrees, fixing the toner onto the circuit board. Printing the circuit without reflection only applies to the circuit placed on the bottom layer. The following is a step by step photo essay of how I made a toner transfer PCB. Ideally the temperature of the PC board would be exactly and uniformly the melting point of the toner, the pressure would be applied directly down, also uniformly, on the entire surface of the toner transfer paper.
