AFA (Aromatic Free) conformal coatings are said to reduce operational hazards for operators due to Toluene and Xylene-free formulation. Consists of AFA, AFA-F, formulated for use in non-atomized film-coat applicators, and AFA-S, for use in atomized spray applicators and HVLP spray guns. Transparent AFA coating is for LED applications, providing clarity and UV resistance, and protection in humid and salt-mist environments, as well as ensuring efficient coating application with a fast touch dry time at room temperature. Is UL approved, meets UL94 V-0. Features UV trace to aid inspection and is reworkable.

DC100 digital precision dispenser adds programmable features, giving more functionality and control over dispensing applications. Alarms can be set to notify when material life has ended or fluctuations in dispensing pressure have occurred. Auto purge function prevents premature curing of material when dispenser is not in operation. Air output and vacuum are now digitally displayed and can be set with tolerances. Can save up to 10 programs; provides five different dispensing modes. Has an I/O connection and lockable programs.

Dow Corning EA-4600 hot melt room temp. vulcanization black adhesive is for assembly of consumer electronics and other high-volume manufacturing operations. Is formulated to dispense easily and achieve instant green strength. Is a reactive material that can be applied as a liquid melt in <0.5-mm-wide bonding lines. Cools quickly and cures at room temp. to become a viscoelastic polymer that provides adhesion to common plastic and metal substrates. Offers service temp. from -40° to 150°C. Softens when exposed to high temp.; reverts to typical properties after cooling. Incorporates UV markers to support automated UV inspection of finished parts. Can be reworked within 24 hr. of application. Is a solventless, one-component, moisture-cure silicone material.

No. 963 is a 250°F, electrically-heated, vertical conveyor oven currently used for curing epoxy. Workspace dimensions measure 30” x 65” x 83”. 30 kW are installed in Incoloy-sheathed tubular elements to heat the oven chamber, while a 6000 CFM, 5-HP recirculating blower provides vertical upward airflow to the workload. Features 4” insulated walls, aluminized steel exterior and interior, top-mounted heat chamber, two independent doors, and 25 product trays, each 24” x 6”, supported by roller chain and driven by a ¾ HP drive motor, controlled by a variable frequency drive. Controls include a digital indicating temperature controller, recirculating blower airflow safety switch, manual reset excess temperature controller with separate contactors, and a tower light to indicate machine status. Is built to JIC/NEMA 12 electrical standards.

Considus dry storage system offers protection for sensitive components and assemblies. Is used when storage under defined conditions of humidity or active component drying is required. Can be used for electronic components, partially assembled electronic modules, printed circuit boards, foils, wafers and components with oxidation-sensitive surfaces. Three dehumidification technologies are available: adsorption dehumidification; nitrogen dehumidification, and compressed-air dehumidification. Achieves <3% relative humidity less than one minute after door closed. Allows humidity-sensitive components in accordance with IPC/JEDEC-STD-033 to be stored indefinitely.
