A no-clean solder paste made from synthetic poly products is said to yield reliable solder joints on surface-mount circuit boards at higher processing speeds due to its superior stencil printing characteristics. With up to 18 hours of stencil life, circuit board assemblers can change shifts or experience brief down times without SynTECH solder paste drying out or absorbing moisture. Unlike organic solder pastes, the new no-clean solder paste requires no refrigeration. The paste leaves a non-conductive, non-corrosive post-reflow residue that acts as a protective coating. It can be used for in-circuit testing of fine pitch solder joints. The formula remains soft and pliable, enabling test probes to pass through the flux without clogging up the probe. The paste comes in jars, cartridges, syringes and cassettes. AMTECH INC., Branford, CT. (800) 435-0317.
