Quality-Driven Production Drives Inspection and Measurement in M2M Communication
Continued from previous page
BF2 software has a common user interface for all of the company’s 3D SPI, AOI and AXI systems. A newly developed coplanarity
inspection algorithm for Saki’s 3Si SPI system can be used to inspect the flatness of lower electrodes for components, such as BGAs, and parts that have narrower pitches and more pins. This prevents insuffi- cient contact of the solder when mounting the parts. The new algorithm inspects
individual parts instead of using the conventional method of inspecting pads. It visualizes the distribution of the solder per substrate with a newly developed SPC function, which achieves improved process quality and traceability. Three keys to Saki’s measure-
ment and tuning function are its offline debugging, warpage adjustment and Fujiyama algorithm. The operator can edit inspection data to check previ- ous good/bad images, or real-time defect images, off-line, without any production interruptions. Warpage is compensated automatically, and an accurate height map is made of the entire PCBA surface, enabling an extra component detection function to detect foreign material. The Fujiyama algorithm pro-
vides complete through-hole joint inspection in a single step. It simul- taneously inspects for copper expo- sure, pin detection, pin-holes, solder fillets, and bridges. A history man- agement system records the detailed data modification system in detail, and inspection accuracy is main- tained by checking the machine sta- tus and inspection conditions before starting auto operation.
Applied Technology The demand for Industry 4.0,
smart factory and M2M communica- tions has fostered collaboration, cooperation and some confusion among companies in the industry, regarding standards, protocols and a drive to be part of the conversation. Equipment manufacturers have set their own requirements for industry partners, and standards and proto- cols vary by organization and region. Saki has embraced them all. Saki’s BF-3Di 3D AOI systems
were the first to be recognized by Panasonic with its APC-MFB certifi- cate for true M2M communication. All 13 models of Saki’s fifth-genera- tion 3Di system have also achieved this certification. Saki is a member of the ASYS PULSE Community and networks its automated inspection and measurement systems with elec- tronic production equipment from other PULSE member companies. Besides Panasonic, Saki is an
integral part of the assembly process for manufacturers that include Fuji Machine Manufacturing and ASM. Saki is part of the Hermes Standard Initiative as well as the JARA-SMT equipment communication protocol standardization subcommittee, a Japanese manufacturing standard. Saki’s new 3D AOI and 3D SPI
systems meet or surpass all the requirements of these initiatives. The rigid structure of the hardware maintains a stable platform, so parameters are consistent and the

data that is fed to the surrounding equipment is accurate. Proprietary software translates the data, so it is usable. The inspection system actu- ally measures as it inspects. The data is communicated to
the adjacent systems and can be used to make course corrections and eval- uate the process in real time. Saki designs its systems to achieve an accuracy level that surpasses what is required for both printing machines and placement equipment. In conjunction with its 3D auto- mated X-ray inspection (AXI) system,
Saki both inspects and measures the entire assembly process, covering screen printing, dispensing, compo- nent placement, reflow, selective sol- dering, and conformal coating. QDP is designed for the smart
factory connection. Producing defect- free products using M2M communica- tion requires maintaining absolute accuracy in inspection, data collection and data transfer in volume manufac- turing environments. Just as the company led the way
with the development of automated recognition through robotic vision
technology, the company’s new fifth- generation 3D automated inspection and measurement systems, which have advanced data capture, intuitive programming, imaging software capa- bilities, and M2M connectivity, are driving quality and production effi- ciency.
