Solder-cream screensThe screens for solder-cream application are produced from bronze plates CuSn6 thickness 0.1 mm , maximum size 300x480 mm. The motif is taken from the Gerber data of the pcb. Generally the pads are on each side diminished by 0,075 mm / totaly by 0.15 mm/. The motif can be deliverd as an extra layer. In this case in will not be changed. After etching the galvanic tin is removed and the customer gets the blanc bronze plate. We can keep the galvanic tin if demanded. |
