3m *Green* Tape 233+. The most common size we use is the 3/4", p/n 26334.
Slightly stronger adhesion than the blue. We still stock the blue for
masking delicate components, like radial resistors, specifically because it
has low adhesion and there is less chance of damaging the components on
demask.
