for solder paste application
In SMD-Technology, the question of how to apply the solder paste is gaining more and more importance.
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 of the paste.
We think that the actual tendency is to go away from screen printing and move towards printing by templates.
The reasons for this change seem to be obvious. To state only some of a 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 both positive or negative pre-sensitized metal templates in many dimension, in different thicknesses and hardnesses.
Brass boards are available in 500 x 1000mm. Thicknesses: 0.2, 0.3, 0.4, 0.5, 0.8 and 1.0 mm. Other thicknesses on request possible.
German Silver (CuNiZn) board size 280 x 1000. Thicknesses: 0.1, 0.15, 0.2, 0.3, 0.4 and 0.5. Other thicknesses on request 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.
Thus, in alteration to an old slogan, one can once again resume:
Out of the plotter in the morning, just ready in the afternoon. With ORIGINAL BUNGARD metal templates.
