The actual phosphorus content in the deposit must be considered.
While the current focus in the electronics industry is chips, components and microelectronics, the printed wiring board (PWB) also plays a vital role. Continued miniaturization and environmental considerations, such Restriction of Hazardous Substances Directives (RoHS), have led the industry to create and improve surface finishes to meet current and future generations of electronic assemblies. Two PWB finishes have become very common: ENIG and ENEPIG. The industry trade association, IPC, released IPC-4552 in 20021 to help standardize the global printed circuit board industry around a specification for ENIG. IPC-4556 was released in 20132 to establish industry standards around ENEPIG surface finishes.
Following its acquisition of ACI, APCT head Steve Robinson is bullish on what's ahead.
APCT in February completed the acquisition of Advanced Circuits Inc. (ACI), a printed circuit board fabricator based in Aurora, CO, and with facilities in Chandler, AZ, and Maple Grove, MN. The acquisition nearly doubles APCT's annual revenue to $200 million, and makes the company the third largest among PCB fabricators in North America behind TTM and Summit Interconnect.
In March, Steve Robinson, president and CEO of APCT, joined PCEA president Mike Buetow on the PCB Chat podcast to discuss the acquisition, the pending integration, and APCT's new responsibilities as one of the largest North American PCB fabricators.

Exhibitors hope new products will keep the order books filled in 2023.
The good times of 2022 carried over into January as the industry turned out for one of the larger IPC Apex Expo trade shows in some time. The San Diego Convention Center show floor was humming for the better part of the first two days of the three-day event, and most of the more than 300 exhibitors seemed pleased with the attendance.
CIRCUITS ASSEMBLY in late January announced the 2023 New Product Introduction Award winners for electronics assembly equipment, materials and software.
The 16th annual NPI Awards recognized leading new products during the past 12 months. An independent panel of practicing industry engineers selected the recipients. The awards were presented during a ceremony in San Diego.
Not leaving enough clearance is a design oversight that can have costly consequences.
As PCB designers, fabricators and assemblers, we wear a lot of hats at Rush PCB. We're always working to design and build PCBAs that are the best they can be. But sometimes we are consigned product to assemble that wasn't designed by our team, and every so often we get boards that tempt us to say, "The designer clearly wasn't thinking about how we are going to build this!"
Taking the confusion out of determining appropriate data collection parameters.
In 1924, Dr. Walter Shewhart was working at Bell Telephone Laboratories. On May 16 of that year, Dr. Shewhart wrote a memorandum in which he presented and proposed the process control chart to his superiors. Bell Telephone Laboratories believed this memorandum gave it a competitive advantage and held this paper internally. In 1931, Dr. Shewhart published his book Economic Control of Quality of Manufactured Product. In this book, Dr. Shewhart explained in detail the fundamental concepts and benefits of statistical process control. This seminal work laid the foundation for the modern quality control discipline, and the process control chart became the bedrock of quality control systems.
