Etch & Plate Resists

Description:

ETA 24 is a versatile Etch/Plating Resist used on high volume Print and Etch PCBs. Suitable for use with alkali Etchants in the pH range 8.0 to 9.5 it can also be used as an acid etch resist. ETA24 is an excellent Plating Resist, capable of withstanding up to 40 amperes and high pH solutions above a pH of 8.0.

• Excellent print definition on hand, semi and fully automatics print formats.
• Fast clean stripping.
• High acid and alkali resistance.
• Versions suitable for hydrofluoric acid etching processes.

Description:

ETAP240 is a contact exposure, negative working photoimageable etch and plate resist, formulated for use as a cost effective alternative to dry film-resist in the manufacture of high density multi-layer PCBs.

It can be applied by air-spray or screen-printing and is suitable for use with alkali and acid etchant solutions and plating solutions. After etching or plating it is easily removed in a sodium hydroxide solution or proprietary resist strippers.

• <25µm (1 mil) resolution capability. • Excellent adhesion and conformance to copper surfaces. • High acid & alkali etch resistance. • Screen print, spray, dip or roller-coat.

Description:

ETP240 is a contact exposure, negative working photoimageable etch resist, formulated for roller or dip coating as a cost effective alternative to dry film-resist in the manufacture of high density multi-layer PCBs.
After acid etching it is easily removed in a sodium hydroxide solution or proprietary resist strippers.

• <25µm (1 mil) resolution capability. • Fast drying speed for high through-put production • Hard tack-free surface after drying allowing layers to be 75° stacked without blocking. • Excellent adhesion and conformance to copper surfaces. • High acid etch resistance. • Roller or dip coat

Description:

Ronascreen 1400 etch resists are formulated to resist attack by acidic and ammoniacal etchants up to pH 9.5. Ronascreen 1400 is rapidly stripped by dilute sodium hydroxide and the resulting solution does not block filters or interfere with the operation of re-cycling systems.

• Cured films are easily stripped into fine particles by a range of inorganic and organic bases.
• Fast, low energy curing gives a dry surface permitting PCBs to be stacked without “blocking”.
• Strong colour gives good contrast against the metallic substrates for easy inspection.
• A range of viscosity and thixotropic index values are available to suit all printing requirements.

Description:

Ronascreen 1400/5160 Flex is a blue, acid resistant, flexible etch resist for use on flexible PCBs, membrane switches and printed electronics. Suitable as a resist over a number of substrates including copper, aluminium and ITO, it is rapidly stripped by solutions of alkali hydroxides or strong organic bases.
Ronascreen 1400/5160 is formulated to allow high squeegee speeds and cure rates with NO compromise on print definition, etch resistance or ease of stripping.

• Highly flexible, crack resistant film.
• Easy and fast stripping in sodium hydroxide as well as organic bases suitable for aluminium.
• Optimise viscosity and thixotropic index to give well defined print features.
