Liquid Photoimageable Coverlay & Solder Mask
Black Liquid Soldermask for Flexible Fine Pitch Direct Imaging
- Ideal for demanding assembly conditions
- No cracking – durable and flexible
- Less than 10 microns of undercut
- High resolution
- Superior chemical resistance
TechniFlex LCL 1000F/423M is ideally suited for demanding assembly conditions, including hot-bar soldering or multiple lead-free reflows. Extensive testing of TechniFlex 423M has shown no cracking after multiple 180 degree bends, even when processing 12-micron polyimide substrate.
This product is RoHS compliant and free from bisphenol A, halogen, Sb, Be and phthalate.
TechniFlex LCL 1000F/423M provides exceptionally fine resolution in a matte black product. With less than 10 microns of undercut, TechiFlex LCL 1000F/423M consistently provides high resolution on 50-micron solder dams with excellent chemical resistance to ENIG, ENEPIG, Ag and Sn finishes.
TechniFlex LCL 1000F/423M is available in three versions:
- TechniFlex LCL 1000F/423M U6 - for direct imaging/manual exposure
- TechniFlex LCL 1000F/423M U7 - for either direct imaging/manual exposure or roll to roll coating operations
- TechniFlex LCL 1000F/423M U8 - Next generation black direct image high heat resistance flexible solder mask
