Huntsman Advanced Materials has introduced two halogen-free laminating resins that comply with regulatory requirements for PCB manufacturing.
 
AZYRAL one- and two-component laminating systems combine versatile processing capabilities with good electrical characteristics and physical properties. Multilayer PCBs and other electrical components fabricated with the materials can withstand exposure to tough operating conditions.
 
Halogen-free AZYRAL XU8282-1 resin is RoHS compliant for Pb-free soldering operations.  This and two-component AZYRAL XTW8291/XTW8293 laminating systems feature easy-to-process, low viscosities for use with FR4 processing. Are nondicy-curing products, meet UL 94 V-O specifications.
 
Said to produce PCBs with a low dielectric constant, low dissipation factor, good surface resistivity and good volume resistivity.
 
Resins are high-temperature resistant materials with low moisture absorption, good thermal stability with glass transition temperatures from 320-482ºF, low coefficient of thermal expansion  and low shrinkage.

Surclean, a division of SMT, will showcase SMT USC400 at the upcoming Nepcon show and in Birmingham, U.K.
 
The portable ultrasonic contact type stencil cleaning system can remove difficult high tack residues such as those found with Pb-free solder materials.

Suitable for offline and on-printer cleaning operations. Stencil cleaning can be carried out on the printer without removing the stencil frame. Can be easily moved between work areas or printers.

An optional ultrasonic mini-bath cleans machine accessories such as placement nozzles, glue dispensing needles, test probes, etc.

Is lightweight for portability, has rugged industrial construction for long service life and is suitable for all stencil materials, even plastic. Suitable for cleaning all printable materials, including paste, inks, resists and SMD adhesives.
