Multi-Seals offers a free engineering sample kit of Uni-form epoxy preforms. Includes a variety of epoxy preform configurations along with an information pack.  Free evaluation samples in specified dimensions and epoxy systems are also available for specific applications. The preforms are an alternative to liquid epoxy for high-volume epoxy sealing applications. 
 
Preforms are one-part epoxy resins that are solid at room temperature. When heated, they melt and cure, forming a consistent seal that protects components from dust, moisture, oil, flux, solvents, conformal coatings and other contaminants.  Close tolerances on preform configurations, consistent pre-mixed ratios of resin to catalyst and consistent viscosity from beginning to end of batch ensure uniform results. 
 
Can be dispensed at 200 to 600 parts/min. with little or no operator training.  Said to eliminate pot-life concerns and cleanup procedures.

LeadHound RoHS/Pb-Free Verification System will verify Pb-free or leaded components, sub-assemblies, PCBs and other items in as little as 15 sec.

Using micro-focus x-ray fluorescence (XRF), can detect the presence of lead, cadmium, mercury, chromium and bromine, as well as other elements, in a safe working environment and provide the percentage of each element found in a tested item. This enables shops to determine if an item complies with RoHS/WEEE directives or military and avionics specifications.

Can test several items in one session and generate a report for most requirements in 30 sec. Generates a report after each test that can be printed or stored as a file to meet applicable documentation needs.

In addition to testing boards and components, can detect lead in BGA spheres and solder paste in pots. 

Can identify which items pass/fail the test and take appropriate action for a facility’s production requirements. In-depth reporting capabilities can tell the percentages or ppm of specified elements in each item.

Runs on a stand-alone, Windows XP-based computer. The x-ray system can be standardized at lunch or dinner breaks midway through production shifts. Power-up automatically initiates a standardization which takes approximately 3 min.
