As far as screen printing is concerned, one has to mention the efforts for the preparation and maintenance of the screen, as well as the questions of its wear out and of the achieved thickness and accuracy of placement of the solder paste.
As time passes there will be a move away from screen printing and move towards solder paste printing by using SMD templates. The reasons for this change seem to be obvious. To state only some of a SMDs template’s advantages, one had to mention the uniformity of the print, the thickness of the transferred paste and the higher durability. But up to now there was one principal problem with templates: They were not easily available.
From now on, there is a quick, cheap and easy way to make your metal template on your own. With already existing machines and without interference of existing processes.
To do so we offer pre-sensitized metal templates in many dimensions, in different thicknesses and hardnesses. Negative working
Brass sheets are available in 500 x 500mm. Thicknesses: 0.2, 0.3, 0.4, 0.5, 0.8 and 1.0 mm. Other thicknesses by request are possible.
Being coated with a chemically resistant photoresist of high line resolution and steepness, these templates offer you all the advantages already known from the pre-sensitized laminates for PCBs. Silver is also available.
