4. Cot voc 6 PCB Fication 6 1 All models PCB s are placed on the base plate of the SP002 so the pads are almost in accordance with holes of the sccreens stencils Undepending the base plate type B V or G we strongly recommend that the surounding areas are also covered with empty PCB s or PCB material of the same thickness This is preventing during printing the damage of the screens or stencils at the edges of the PCB and ensures a long life of your screens stencils Example Baseplate Printer Surounding PCB material Squeegee length 6 2 Fixation on model B Flat Base Plate The easiest way is to fix the surounding PCB material with doublesided adhesive tape In this way you establish a kind of mask where you can simply lay into the PCB which has to be printed 6 3 Fixation on model V Vacuum table Same procedure as on model B Use also surounding PCB s for preventing damges on screens and stencils Additionaly the same material is used to cover the vacuum holes The vacuum plate is usually used for bended or flexible thin PCB s as they are hold properly into position due to vacuum suction The commection for the vacuum is below the printer Optional availble is an extemal vacuum pump 6 4 Fixation of PCB on model G Groove table With the within the groove slideable plates with fixing pins almost every position of a PCB can be defined by using the pinholes of a PCB Therefore no adhesive tapes are encessary on
