PRO 2 Tdp is a tabletop assembly cell that may be used for low- to mid-volume manufacturing operations that require an LED component be picked, placed and soldered onto a PCB or substrate. The onboard dispensing head also can place a dot of thermal paste or silicon adhesive between the PCB and LED prior to attach. The robot selectively solders with twin irons attaching each side of the LED simultaneously. Dual automatic solder feeders, pre-heat plate and thermal loop feedback are standard.
 

 
Bench length and height depends on the specific process, but standard floor-to-tabletop height is 30 in. Standard widths are 2-1/2 in. over nominal 3, 4, 5, 6, 8 increments and the interior depth (interior table or working space) is 21.5 in. Overall cabinet width, depth and height will depend on the size of unit chosen.
 
Clean HEPA-filtered air flows outward from the cabinet. This horizontal laminar flow air washes out particulates and prevents contamination from entering the clean work zone. The cabinet features “clean edge” construction that puts the hood and tabletop in shear with the media edge of the HEPA filter to reduce turbulence along the sides of the hood, improve laminar flow and prevent contamination infiltration around the perimeter of the hood. 
 
Top and bottom front grills recirculate the air within the bench. Provides recirculating temperature control to within ± ½ºF.  Can operate at or above ambient using make-up air for cooling, or it can have an air conditioning unit with reheat for temperature control at or below ambient.

Model 2200-245-051 Tip-Seal dispense valve is for precision dispensing of low- to high-viscosity flowable materials. It is also used in high-speed stitching or repetitive on-off applications where short segments of material are deposited onto a surface.
 
The zero-cavity design helps dispense solvent-based, moisture-curing and stringy materials such as silicones or polyurethanes. Sealing at the tip prevents material from hardening in the nozzle, oozing or dripping. The valve opens and closes its material passage at the tip of the nozzle to precisely start and stop material flow.
 
Pneumatically actuated, the valve has a carbide tip, titanium-coated shaft, hardened seat and wear-resistant fluid seals to extend valve life. The stroke adjuster can set the needle opening to change material-flow rates and bead-profile sizes.
 
The valve’s precision dowel and screw holes allow easy and accurate mounting. The 0.125” orifice and short 0.32” tip length (8.1 mm) enables the valve to reach into parts and fixturing. Other orifices and tip lengths are available. Material is delivered to the valve by either a metering assembly or under regulated pressure from supply tanks or pumps.
 

ENVIRON provides web systems for managing WEEE compliance for business products, and the group has launched a new customer relationship module. 
 
Hosted on the company’s Website, the system enables companies to gain feedback from its customers on product satisfaction and after-sales service. Customers wishing to use the WEEE collection and recycling system are required to complete a marketing questionnaire which is emailed to the company.  As part of the questionnaire, customers are required to enter valid model numbers to use the system.
 
The WEEE web system:
Provides a single contract to manage producer registration, in-country recycling, and compliance reporting in all Member States;
Provides straightforward collection arrangements, which the company can communicate to business end-users through their own company website;
Offers a single corporate solution that can be expanded to cover other countries;
Includes the option to pass collection costs on to business end-users;
Provides flexibility and control of future WEEE recycling arrangements, enabling companies to ensure that recyclers continue to provide competitive rates for their services, and change recyclers in individual Member States to take advantage of new recycling technologies and techniques;
Demonstrates to customers that the company is compliant with the WEEE Directive and has addressed its environmental responsibilities.
