Laser Cutting Residues

Substrate: Flexible Electronic Substrates Contamination Challenge: A Laser-based cutting process produces a conductive carbonaceous soot on the polymeric surfaces along the Laser cut pattern which must be removed prior to next steps in the device fabrication process. The soot is a potential cause of electrical shorts and interferes with subsequent electroplating operations. Solution Robotic CO2 Composite…

Fiber Optic Residues

Substrate: Fiber Optic Residues Contamination Challenge: During polishing , assembly, test, or day-to-day use of fiber optical devices, the various light-transmitting surfaces and interfaces become contaminated with particles, polishing compounds, adhesives, and fingerprints. This contamination must be removed from the light-transmitting surfaces to prevent obscuration or attenuation of light. If not removed, surface contamination can…

Resistive Residues (CRES)

Substrate: IC Test Socket Contacts Contamination Challenge: IC test socket contacts must be cleaned periodically to remove resistive residues (CRES) comprising a complex mixture of metals and oxides and organics from an chip test socket contacts. Maintaining low CRES prevents false negatives or other aberrations during automated electronic circuit testing. Solution Manual CO2 Composite Spray™ cleaning…

Magnetic Particles

Substrate: Magnetic Latches Contamination Challenge: During magnetic latch assembly operations, microscopic magnetic particles must be removed from strongly magnetized surfaces to meet a stringent particle cleanliness specification. Solution Manual CO2 Composite Spray™ cleaning process and system. Benchtop spray cleaning system with footswitch control Single CO2 composite spray applicator – pendant style Local exhaust plenum to remove…

Laser Welding Oxides

Substrate: Laser Welding Contamination Challenge: A Laser-based welding process causes the formation of a brown metallic oxide soot uniformly distributed on the exterior surfaces of the titanium alloy electrode surface. The oxide soot is produced during melting of the titanium alloy electrode and attachment to a mating connector body. The oxide soot is toxic to the…

Solder Flux Residues

Substrate: DC Power Supply Contamination Challenge: Following a soldering process, solder flux residues and metallic oxides must be removed from the various soldered terminal surfaces. Solution Manual CO2 Composite Spray™ cleaning process and system. Benchtop spray cleaning system with footswitch control Single CO2 composite spray applicator – handgun style Local exhaust plenum to remove contamination Sprayed…

Microscopic Particles

Substrate: Hard Disk Drive (HDD) Motor Base Assembly (MBA) Contamination Challenge: During HDD component rework and precision assembly operations, microscopic particles must be removed from surfaces and threaded features of a motor base assembly (MBA) with ferrofluidic spindle motor in place to meet a stringent particle cleanliness specification. Ferrofluidic spindle motor seals cannot be chemically or…

Laser Processing Residue

Substrate: Ceramic Chip Carrier Contamination Challenge: A Laser-based manufacturing process produces particle-based contamination on and around an L-shaped circuit pattern which must be removed prior to the next step in the proprietary fabrication process. Solution Robotic CO2 Composite Spray™ cleaning process and system. Benchtop Cartesian robot Robot has an end-of-arm spray tool (EOAT ) comprising a…
