RBP Releases Circutek CC-720 PTH Acid Cleaner Conditioner
August 4, 2020 | RBP Chemical TechnologyEstimated reading time: Less than a minute
RBP Chemical Technology has recently released Circutek CC-720 PTH Acid Cleaner Conditioner.
Circutek CC-720™ is an acidic cleaner/conditioner for use in the electroless copper metallization process in the PCB industry. It is formulated to remove fingerprints, light soil and other contaminants from copper foil. It also conditions non-metallic surfaces including glass fiber fabric and multiple resin systems used in the construction of high-reliability rigid, rigid-flex and flexible printed circuit boards.
The Circutek CC-720 is formulated to affect maximum adsorption of palladium tin catalyst to insure uniform deposition of the subsequent electroless copper deposit.
Positive Customer Impact
Circutek CC-720 provides the fabricator with wide process latitude with respect to enhancing the chemisorption of the palladium-tin catalyst without building up a heavy conditioning film on the interconnect and resin-glass surfaces. The Circutek CC-720 is acidic in nature and is free-rinsing. Many competitive conditioners on the market often over-condition the resin, leaving it difficult to rinse film. This excessive film causes over adsorption of the catalyst that often leads to defects such as hole-wall pullaway (HWPA) and interconnect defect (ICD)
The Circutek CC-720 is another innovation in RBP’s Circutek PTH Process Technology portfolio.

Trump Copper Tariffs Spark Concern
07/10/2025 | I-Connect007 Editorial TeamPresident Donald Trump stated on July 8 that he plans to impose a 50% tariff on copper imports, sparking concern in a global industry whose output is critical to electric vehicles, military hardware, semiconductors, and a wide range of consumer goods. According to Yahoo Finance, copper futures climbed over 2% following tariff confirmation.
Happy’s Tech Talk #40: Factors in PTH Reliability—Hole Voids
07/09/2025 | Happy Holden -- Column: Happy’s Tech TalkWhen we consider via reliability, the major contributing factors are typically processing deviations. These can be subtle and not always visible. One particularly insightful column was by Mike Carano, “Causes of Plating Voids, Pre-electroless Copper,” where he outlined some of the possible causes of hole defects for both plated through-hole (PTH) and blind vias.
Trouble in Your Tank: Can You Drill the Perfect Hole?
07/07/2025 | Michael Carano -- Column: Trouble in Your TankIn the movie “Friday Night Lights,” the head football coach (played by Billy Bob Thornton) addresses his high school football team on a hot day in August in West Texas. He asks his players one question: “Can you be perfect?” That is an interesting question, in football and the printed circuit board fabrication world, where being perfect is somewhat elusive. When it comes to mechanical drilling and via formation, can you drill the perfect hole time after time?
The Evolution of Picosecond Laser Drilling
06/19/2025 | Marcy LaRont, PCB007 MagazineIs it hard to imagine a single laser pulse reduced not only from nanoseconds to picoseconds in its pulse duration, but even to femtoseconds? Well, buckle up because it seems we are there. In this interview, Dr. Stefan Rung, technical director of laser machines at Schmoll Maschinen GmbH, traces the technology trajectory of the laser drill from the CO2 laser to cutting-edge picosecond and hybrid laser drilling systems, highlighting the benefits and limitations of each method, and demonstrating how laser innovations are shaping the future of PCB fabrication.
