Bransonic CPX Ultrasonic Baths

Bransonic CPX ultrasonic baths feature digital controls with power tracking capabilities to adjust for light or heavy loads, high/low power control, degassing and sleep mode.

The CPX baths offer the following features:

• Sweep frequency eliminates standing waves and creates consistent cavitation throughout the tank.
• 40kHz rugged industrial transducers.
• 99-minute digital timer with continuous ultrasonic operation.
• Last stored parameters are recalled with unit is turned back on.
• Constant activity/power tracking automatically maintains the ultrasonic power by adjusting for changes in liquid level and temperature caused by a light or heavy load.
• Degassing and conditioning the solution: Degassing period can be set up to 99 minutes - extended degas time periods allow for "beyond" cleaning applications such as sample preparation, which includes degassing liquids, mixing and homogenization, dissolving solids, cell lysing and dispersion of particles.
• High/low power control: When cleaning delicate parts, the CPX allows the user to lower the amplitude of the acoustic energy in the bath: 100% power to the tank for normal applications, 70% power for delicate applications.
• Controls are located above and behind the cleaning tank in an easily accessible control tower panel and raised above the tank to avoid damage from cleaning solutions.
• Convenient built-in pour drains are featured on 0.5 and 0.75 gallon models. Tank drains with valves are incorporated on models 1.5 gallon and larger.
• Plastic body, chemical-resistant.

Isopropyl Alcohol

EWD Solutions offers two formulations of Isopropyl Alcohol (IPA) and one eco-friendly alternative to IPA, all from leading manufacturer Techspray.

99.8% Pure Anhydrous Isopropyl Alcohol is excellent for defluxing, stencil cleaning, tape head cleaning, other light cleaning and as a flux thinner. Avoid "bargain" alcohols for critical electronic cleaning. Cheap alcohols contain much more water, which slows drying and can cause oxidation, while "denatured" alcohols leave residues. Non-ozone depleting. Available in presaturated wipes, in an aerosol can, trigger spray bottle and in bulk quantities.

70% Isopropyl Alcohol, 30% DI Water is ideal for effective and economical stencil cleaning. Does not contain a denaturant and is non-ozone depleting. Available in presaturated wipes and in bulk quantities.

Eco-Stencil Manual Stencil Cleaner is an eco-friendly alternative to IPA. It effectively removes all types of solder paste (e.g. water­based, RMA, no­clean, lead-­free) and uncured adhesive from screens, misprinted boards and equipment. Completely safe on stencils, squeegees, and equipment surfaces. Ideal replacement for IPA cleaners, which are often prohibited because of safety and environmental restrictions on VOC emissions or waste disposal issues. Non-flammable, non-ozone depleting, low VOC, zero GWP and biodegradable.

Kester Lead-Free Wire Solder

EWD Solutions offers several types of Lead-Free Wire Solder from Kester.

Lead-Free No-Clean 275 Wire Solder: Kester® 275 No-Clean Flux for cored solder wire was developed to provide superior wetting performance for hand soldering in the electronics industry. The chemistry is based on some of the same principles that have been safely used for years in mildly activated rosin fluxes. The use of 275 No-Clean Flux results in an extremely clear post-soldering residue without cleaning. The unique chemistry in Kester 275 was also designed to reduce spattering common to most core fluxes. Kester 275 can be used for both lead bearing and lead-free soldering.

Lead-Free Activated Rosin 48 Wire Solder: Kester Activated Rosin flux is a very high activity rosin flux used for difficult to solder metals. It was developed for lead-free applications to enable soldering of most common metals and has performance characteristics far exceeding standard RA fluxes. It builds on the performance of its 44 Rosin Flux predecessor with instant-action wetting to provide fast and reliable solder joints.

Lead-Free Water Soluble 331 Wire Solder: Kester® 331 Organic Flux is a water soluble formula for use in flux-cored wire. This cored solder version of the popular 2331-ZX Neutral Organic Water Soluble Liquid Flux is more effective than rosin fluxes in soldering difficult metals. The same fast action and mild properties are exhibited with 331 Organic Flux as with the liquid 2331-ZX. This flux is more heat stable than most organic fluxes, resulting in minimal smoke and odor. The residue can be completely removed with a simple water rinse.

Many other Kester products are available at EWD Solutions including bar solder, solder paste and solder flux.

Kolver FAB Series Electric Screwdrivers

FAB series electric screwdrivers feature an advanced ergonomic design, ease of use, high accuracy and durability that have made these drivers the standard which all others are measured. They are lightweight, compact, powerful and come standard with ESD Safe housing certified to SP method 2472 (Ericsson approved).

The torque is set externally: an adjusting nut controls output torque by changing the clutch spring compression. A reference scale will indicate the torque setting. The low voltage 30 VDC rare earth motors combine high performances and long life. Replacing carbon brushes and regreasing gears every 400,000 cycles is all you need for maintenance.

The motor works in combination with a control unit, sold separately. The electronic control circuit cuts the power supply to the motor in response to the clutch action, as soon as the pre-set torque has been reached. In addition, the controller can be supplied with torque reached signal, lever signal, remote start and reverse and with ACE screw counter unit.

The drivers come standard with an ESD Safe body, 8' connection cable and suspension bail. The new heavy-duty cables and connectors, developed for robotic applications, are made of antistatic dissipative material for a safe use in ESD environment.
