A sharp knife and a steady hand. Sorry that is the only way I know because I have had to do it.

Several methods work well.

1. (Low Volume Method) Using an Xacto blade, scrape off the solder mask holding the blade flush being careful not to use the pointed part of the blade.

2. (High Volume Method)Tape off the area that you don't want the mask to be removed from, or make a stencil and sand blast the mask off using a small sand blaster.

3. (Messy and not so reliable method) Contact the manufacturer of the mask you are using and see if they make a removing solution for that mask.

4. (Fast & relaible method) Send it to the skilled professionals at Precision PCB Services, Inc. and we can provide you a written quote and free sample rework.
