Data correction – printing

Print on solder pads

Does your design system generate prints (silkscreen) on solder pads or thin line labels? You need not waste your time with manual corrections. We do this for you while processing your PCB production data using an automated method.
This correction is necessary to utilize the option of a 100% electric test as a prevention of problems in PCB assembly with components.

Data correction – masking

Solder mask overhang

To prevent problems in PCB production and, mainly, in PCB assembly, solder mask should overhang the pads in adjacent layers (top and bottom) to a certain degree. Design systems, depending on their settings, mostly generate this overhang incorrectly, resulting in avoidable complications.
Therefore, we recommend generating solder mask pad size as 1:1 with solder pads. We then take care of this issue while processing your PCB production data in an automated manner.
If the width of a gap between SMD pads in the artwork is below 200µm, we are technologically unable to achieve the bridge in the solder mask. The smallest bridge width is at least 120µm.
