EMP110 Laser Direct Imaging (LDI) Technology
EMP110 LDI incorporates the latest in photoinitiator and polymer technologies to provide a soldermask capable of low energy imaging by laser as well as standing up to the demands required of a soldermask:
- Low energy requirement (approx. 50-60 mJcm-2)
- Low tack surface during exposure
- Good resistance to ENIG and immersion Sn
- Compatible with lead-free soldering processes

EMP110 Spray Technology
Since 1993 Electra has been the market leader in the development and manufacture of soldermasks for application by electrostatic spray and conventional air-spray. Widely accepted by spray machine manufacturers as the spray soldermask benchmark; EMP110 is specially formulated and quality controlled to deliver exceptional track-edge coverage in combination with excellent cosmetics. These features allow EMP110 to give improved coverage, often at a reduced coating thickness and reliably provide our customers material savings over competitor materials.
- Excellent track encapsulation and coverage up to 400μm copper heights
- Fine pitch track and gap encapsulation without skipping or dewetting
- Smooth surface coatings without excessive ink loss
- 100% encapsulation of blind-vias
- No bubbles
- Increased yields and reduced cost-in-use

EPIC L SF60 LPI Soldermask
EPIC LSF 60 is a negative working, liquid photoimageable, two component soldermask which is designed for high volume aqueous processing of printed circuit boards and other high-end electronic applications. LSF60 has been widely used in Europe as well as Asia and carries large OEM acceptance, approval and specification.
- Suitable for screen-printing and curtain-coating applications
- Quick tack-dry cycle allowing rapid, high volume through-put on all types of dryer
- Excellent track-coverage without skipping or micro-bubbles
- Hard surface after tack-dry even in high deposit areas (i.e. from curtain-splitters)
- Very high resolution capability sub 50μm (2 mil) with clean developing of small via-holes
- Excellent resistance to immersion Sn chemistries
- High chemical and environmental resistance properties
- Latent image after exposure
- All versions are RoHS compliant, SM840 qualified and UL-94V-0 rated
Available in green with either a gloss or matt finish.
