No-Clean Solder Paste has lead-free, synthetic formulation.

Press Release Summary:



Made with 100% synthetic poly adduct components and suited for SMT assemblies, SynTECH-LF is compatible with tin/silver and tin/silver/copper alloys. Synthetic, non-organic formula optimizes lot-to-lot and stencil printing consistency and offers 12 hr stencil life and 12-16 hr tack time. Product leaves removable, non-conductive, non-corrosive, post reflow residue that acts as protective coating and is also compatible with organic solderability preservatives without compromising SIR values.



Original Press Release:



SynTECH-LF(TM) is the World's First RoHS-Compliant Lead-Free, Synthetic, No-Clean Solder Paste



Branford, CT - AMTECH Inc., a leading supplier of solder powders, pastes, fluxes and associated products used in electronic assemblies, now offers SynTECH-LF, the world's first and only no-clean solder paste formula made with 100% synthetic poly adduct components.

Ideal for SMT assemblies, and compatible with tin/silver and tin/silver/copper alloys, SynTECH-LF synthetic solder paste offers the following productivity-enhancing benefits:
  • Higher production yeilds
  • Synthetic, non-organic formula for unparalleled lot-to-lot and stencil printing consistency
  • Wider process windows (12-hour stencil life and 12-16 hour tack time)
  • RELO flux designation
  • Exceeds IPC SIR testing requirements
  • 1.56% BONO copper mirror
  • ICT friendly, and compatible with organic solderability preservatives (OSPs)
  • 88.5% metal loading

    With lead content guaranteed at <200 ppm, SynTECH-LF conforms to the European Union's Reduction of Hazardous Substance (ROHS) directive requiring the elimination of Pb from use in PC board assemblies manufactured in Europe after July 1, 2006.

    SynTECH-LF features 12-hour stencil life and 12-16 hour tack time so PC board assemblers can change shifts or experience brief periods of downtime without the solder paste drying out or absorbing moisture. Other product benefits include superior stencil printing characteristics and ideal viscosity, grain size and particle sphericity (even at higher melting temperatures), resulting in higher quality solder joints at higher processing speeds with fewer solder balls or voids. SynTECH-LF also leaves a non-conductive, non-corrosive, post reflow residue that acts as a protective coating, and can easily be removed using Kyzen® or Petroform® solvent cleaners.

    SynTECH-LF is ideal for in-circuit testing (ICT) of fine pitch solder joints, as the residue from this unique lead-free formula flows off-filet to the solder mask, making pin testing simpler and more accurate because the testing can be done directly on the solder joint. SynTECH-LF is also compatible with organic solderability preservatives (OSPs) without compromising SIR values. SynTECH-LF lead-free synthetic solder paste comes in jars, cartridges, syringes and cassettes.

    AMTECH Inc. is an ISO-9001 certified supplier of advanced SMT solder pastes and companion products for the board assembly market, including liquid fluxes, bar solder, core wire, and assorted wipes and cleaners. AMTECH is known worldwide for product innovation and quality, competitive prices, excellent customer service and superior technical support.
