Benchtop cleaner applies ultrasonics to PCBs
The TTC 2530 is a bench-mounted four-stage ultrasonic cleaning machine for printed circuit boards or electronic assemblies.
Optical inspection system sets industry standard
The innovative Ersascope optical inspection system is officially the world's industry standard system for visually inspecting BGAs, Micro BGAs, Flip chips etc.
A foam fluxer is fitted as standard to the base machine, but the Blundell "Target" spray fluxer with automatic PCB length and width sensing, can be fitted as an option.
Preheating is by long-wave infra-red and consists of an 800mm long hotplate with built in temperature graduation.
The preheating ramp is designed to match the requirements of lead free processing and there is no need for a time dwell over the preheat, so the machine is a continuous throughput system.
The solder bath holds approximately 230kg of lead-free solder alloy, and is vitreous enamel coated.
All the solder nozzles, ducting and the impeller are treated with a special tin erosion resistant material, ensuring complete safety for use with all grades of Pb-free alloy.
The machine can be supplied with a single laminar solder wave for through-hole soldering, or a chip wave and pump can be added for underside adhesive bonded SMT or mixed technology work.
To protect against dross and to reduce solder bath maintenance, the System 300 is fitted as standard with a localised argon inert gas system in the area around the solder pump shafts.
The argon is available in small cylinders at low cost and is claimed by Blundell to reduce solder bath maintenance by at least 50%.
It is unlikely that users will need to remove the solder nozzles for cleaning more frequently than once a year.
The extruded aluminium conveyor rails are chain driven.
Both rails have drive power and the adjustable soldering carriers have titanium fingers and are available with centre rails.
The full width of 300mm can be used, and there is no limit to the PCB length.
The System 300 is designed and built in the UK by Blundell Production Equipment.
