Ronascreen SPSR™ 5600 LPI Soldermask

Ronascreen SPSR™ 5600 is a liquid photoimageable soldermask which is applied by horizontal or vertical screen printing techniques and is designed for contact-exposure and development in aqueous sodium or potassium carbonate. Ronascreen SPSR 5600 delivers excellent resistance to electroless nickel and gold processes (ENIG). Use of Ronascreen SPSR HL-2 Catalyst with standard SPSR 5600 series inks gives a hard, non-tacky surface with easy artwork positioning and no sticking.

• High resistance to ENIG surface finish chemistry
• Fine solderdam resolution down to 50μm (2 mil)
• Clean developing of small via-holes
• Excellent screen-printing coverage without skipping or micro-bubbles
• Fast exposure speed for high through-put
• Rapid tack-dry cycle for high through-put without artwork sticking or marking
• All versions are RoHS compliant, SM840 qualified and UL-94V-0 rated

Available as gloss or matt finish in green, blue, red, yellow, white and black.
