4.General features and advantages of the peelable solder mask are:
● Time and cost saving process compared to taping
● Protection of complex structures and shapes by efficient screen-printing
● Protection of selected areas on the PCB during various finishing or assembly processes
● Protection (tenting) of plated through holes (PTH)
● Overprinting of carbon inks
● Resistance in plating processes (e.g. electroless/electrolytic Copper or Tin plating)
● Protection during Flex or Flex-Rigid processing
● Easily removes and leaves no residue
● Non-contaminating, non-staining, and non-corrosive
● RoHS Compliant
● Used with lead-free or tin/lead processes
● Stable to 550°F (288°C)
● Phthalate-free, low toxicity and environmentally safe
● Compatible with rosin, no-clean, and water soluble flux types
● Can cover holes up to 0.120"
