4 Techniques for Removing Solder Mask

This technique is most effective when removing solder mask from copper planes or soldered surfaces. Masking tapes or other protective materials should be placed on the circuit board surface to isolate the area to be stripped. The chemical stripper is then applied with a brush or swab. Since the stripper is liquid, it is often difficult to control. Circuits Assembly Online Magazine - Solder Mask and Low The solder mask impacts the component standoff height. Of the three options solder-mask defined (SMD), non-solder-mask defined (NSMD), or no solder mask (NoSM) NoSM can increase the standoff height, which may enhance the cleaning process. Standoff height will vary depending on board design and component selection, so it is difficult to quantify standoff height for each solder mask selection
